Singapore 6.5 million population: Islandwide mega jam

Vehicles lined end to end will fill tightly every metre of main roads, espressways

Zhen Ming, The New Paper 15 Nov 08;

IMAGINE a nightmare day when every motorist in Singapore decides to travel at, say, 8am.

The vehicles clog up every main road and expressway bumper to bumper - such that none can move even a metre forward.

Yes, this can happen now.

By 2025, if all the projected 1.2 million motor vehicles we own by then were lined up, then they would occupy a total of 3.8 lanes of all our major roads.

That's when there'll be at least 6.5 million of us living on the island.

So, if all of us go out on the road at the same time, we'll have a mega jam.

Back in 1982 (when I first returned from America), when there were only 2.5 million of us, we were already close to gridlock with 3.2 lanes jam-packed.

Thankfully, a road expansion programme managed to keep pace with the rapid rise in car ownership in recent years, ensuring that the number of lanes occupied on a bumper-to-bumper basis was kept at 3.2 (to this day).

But this can't go on forever.

With 12 per cent of our land already allocated to roads, road expansion is slated to slow down to only 0.5 per cent yearly from 2009 onwards.

And while the vehicle population will still be allowed to grow at 1.5 per cent (that is, thrice as fast), the longer-term outlook for car ownership is definitely not too rosy.

Singapore's transport system must therefore be overhauled, yet again, if we are to soon realise our aspirations to be a thriving congestion-free global city.

A world-class global city of 6.5 million people will soon put us in a different league - not too far behind the likes of Paris (9.6 million), London (7.6 million), and Chicago (6.9 million) - but it will also mean a more crowded Singapore.

Faster than you may imagine, we will have to figure out how best to feed, shelter and move around 6.5 million people - instead of just the 4.8 million we now have.

Trust me, this target population will be hit - within the next 7-17 years - whether you think the country's population should continue to grow as fast as it did over the past three years (4.3 per cent a year, with the intake of more foreigners), or at a slower 'natural' rate (1.7 per cent a year, without new immigrants).

So, like it or not, whether it's mid-2015 (fast track) or end-2025 (natural pace), let's brace ourselves for 6.5 million of us - each with an average land area of only 109sqm (versus a more spacious 250sqm back in mid-1982).

This bigger population, in turn, calls for radical changes to vastly improve our existing land transport system, which must include enhanced measures to restrain the number of motor vehicles as well as our propensity to take them out for joyrides.

More ERPs?

With this in mind, expect Singapore motorists to face stiffer usage disincentives to ensure smooth-flowing traffic on our roads.

Expect the Electronic Road Pricing (ERP) system to play a more prominent role.

Expect ERP coverage to be more extensive and ERP charges to be much higher. And expect the so-called ERP II (the next generation ERP system) to soon make distance-based congestion charging possible.

That's because the Certificate of Entitlement scheme, blamed for failing to check the explosive growth in car ownership in recent years, is too dependent on the anticipated number of vehicles to be scrapped - a less-than-accurate forecast that requires fine-tuning.

Futile

Even with the lowering of our vehicle population growth rate to 1.5 per cent a year (from the present 3 per cent), with effect from Quota Year 2009, holding back the tidal wave of cars seems, to me, akin to King Canute's futile seaside attempt.

Given our land constraint, the projected increase in travel demand must be met largely by public transport.

A single-deck bus, for instance, can transport about 80 passengers at any one time, whereas the average occupancy of our cars is only about 1.5 persons per car.

Expect, therefore, more bus services and new roads built partly or wholly built underground.

However, these roads won't come cheap. So guess where we can expect the money to come from?

Prof Leo Tan: Nature lover returns to his roots

Leo Tan hopes to work on marine biology in his post as NUS special projects director
Tania Tan, Straits Times 15 Nov 08;

PROFESSOR Leo Tan was part of a small elite team that helped set up the National Institute of Education (NIE), when it was commissioned in 1991 by then-education minister Tony Tan.

He spent 13 years as director of the institute before stepping down in 2006, when he took on an advisory role as professor of biological sciences at the Nanyang Technological University (NTU).

The former National Parks Board chairman, an avid nature lover, has been a key figure in championing the conservation of Singapore's unique biodiversity. He helped ensure that Labrador Park - Singapore's only rocky coast - was gazetted as a nature reserve.

Now, he leaves NIE for his 'home' in the National University of Singapore (NUS), where he began his teaching career in 1973.

He will be the university's new director of special projects, which will include setting up a joint master's programme for science communications.

Prof Tan will also help to develop an integrated programme to foster the talents of promising science undergraduates who wish to pursue a multi-disciplinary PhD course.

He spoke to The Straits Times about his career and plans:

# How do you feel about leaving after 18 years?

I will miss the people. But I am not too sad because I like to think I am working for Singapore Inc. It does not matter where I am, because ultimately we are all working together towards the same goal - a better Singapore.

# Why the decision to move now?

NUS had made the offer previously, but I felt that I owed it to NIE to stay on and help. Now I think it's time I did something for myself. I want to be able to experiment and maybe try some things I have always wanted to do. I want to go back to my roots - marine biology. I hope to spend more time researching, helping out on projects relating to our coastal areas.

(Prof Tan will be lending his expertise to the newly launched Project Semakau - a three-year programme by the Raffles Museum of Biodiversity Research to document and record unique species of marine flora and fauna on Singapore's artificial landfill, Pulau Semakau. The project is funded by HSBC Bank and supported by the National Environment Agency.)

# You have accomplished a lot in your 64 years. Don't you think it is time to retire and enjoy life?

I don't think I will ever be able to retire completely. I cannot sit still. Plus I do not consider what I am doing as 'work' - I love what I do.

# How can our education system be improved?

We should not be closeted in our mindsets. We cannot make people study subjects based on whether the topic will be able to help them earn money in the future.

If a person wants to study astrophysics, we should not say tan bo jiak (Hokkien slang phrase for being unable to earn a lot of money). We should recognise that this person could be a successful venture capitalist, or financial analyst, because astrophysics requires an understanding of some very complicated mathematical calculations. I studied marine biology, which was so cloistered that everyone thought my future was doomed. But it fostered in me a love for the environment, and everything turned out okay in the end.

# What do you consider your biggest accomplishment at NIE?

I had hoped that we could make science something that even the layperson can enjoy. Bringing science to the masses has been a dream that has taken 25 years to bear fruit. Looking at the education system now, and the fact that science is taught in schools, and made fun through places like the Science Centre, it is a great feeling to see a dream realised.

# What other dreams do you have yet to fulfil?

Bringing science to the masses was one. Another is that the universities will one day consider offering an undergraduate environmental science degree. I think it could help equip young people with the right tools to benefit the environment. It is also the culmination of multi-disciplinary learning - science, history, geography.

We are too used to sticking to our disciplines, too used to our own fields. We should be schooled in different fields. No more working in silos.

The last dream I have is to one day set up a natural history museum, documenting all of Singapore's plants and wildlife. We have a unique biodiversity that all Singaporeans should be able to share and experience.

3-year census of marine life on Semakau

'Garbage of Eden' findings to be put online for free use
Tania Tan, Straits Times 15 Nov 08;

IT MAY be a wasteland but the Semakau Landfill is teeming with life.

Just how much life and what kind? Researchers have started a three-year census of marine species - including coral, crustaceans and fish - living near Singapore's first artificial landfill to find out.

Project Semakau, a project spearheaded by the National University of Singapore's Raffles Museum of Biodiversity Research, could also be the first steps towards making the landfill a marine conversation park.

Scientists plan to publish their findings in an online database as a free resource for nature enthusiasts and researchers alike.

Senior Parliamentary Secretary (Environment and Water Resources) Amy Khor launched the project yesterday at Pulau Semakau, which is about 8km south of Singapore.

The project will serve as a baseline for monitoring the island's rich biodiversity, which will help establish the ecological value of Semakau, said Dr Khor.

Another aim of the project is public education.

More than 200 volunteers will be recruited and trained by the museum to help conduct tours of the shores during low tide for schools and the public.

The volunteers will also help researchers document and record species of plants and animals on the island.

By getting schools and members of the public involved, the organisers are hoping for a 'multiplier effect', with more people spreading the message of conservation, said Professor Leo Tan, who helped conceptualise the project.

'Semakau highlights Singapore's ability to strike a delicate balance between the needs of an urban city and nature conservation,' said Prof Tan, who is also the director of special projects for NUS.

Created in 1999 by merging Pulau Semakau with the neighbouring Pulau Sakeng, the island has become a showpiece for eco-friendly urban waste management.

International magazine New Scientist called Semakau the 'garbage of Eden' in an article about the island last year.

Site visits for members of the public and foreign dignitaries are conducted regularly.

Despite being a landfill, Semakau has several well-defined habitats, including mangrove swamps, forests and coral beds, said Prof Tan.

'None of these has suffered severely from being sited next to a landfill,' he added.

The funding of $600,000 for outreach, research and conservation activities will be provided by London-based HSBC Bank.

The project has the support of the National Environment Agency, which is also looking into using the island as a testbed for clean energy technologies.

And with possibly several unique species of flora and fauna to be found on the island, a database could give policymakers concrete reasons to declare the island a marine park, said Prof Tan.

'It's a vision we all can be part of,' he said.

Updates on tiger attack at Singapore zoo

Tigers stressed by the incident
Straits Times 15 Nov 08;

THE two white tigers involved in Thursday's attack on a cleaner are exhibiting symptoms of stress.

Normally relaxed and languid, they are now on constant alert, zoo officials said yesterday. Their ears are pricked up, and they are breathing heavily.

Only Winnie and Jippie, the two female cats which carried out the attack, are showing these symptoms.

The other white tiger in the enclosure, Omar, a male, showed no interest in the cleaner, Mr Nordin Montong, 32, and stayed well away from him.

Omar is behaving normally.

The two other cats are stressed out because of the commotion that occurred during the attack, said the zoo's assistant director Biswajit Guha.

Onlookers screamed and keepers flung objects at the animals to try to distract them on Thursday.

The cats' heightened senses were thus thrown off-kilter, Mr Guha said, adding that they were probably traumatised because they had not experienced anything like it before.

It was also the first time they had come into close contact with a human being since they arrived in Singapore from Indonesia seven years ago, Mr Guha said, and their sense of smell was probably affected.

Even during feeding and cleaning, keepers stay well clear of the big cats.

When meal times roll around, a keeper lures the cats into a holding area behind the exhibit, places about 5kg of raw meat in the enclosure, then leaves it before letting the cats back in.

Mr Guha said: 'The rule is that no one is allowed to enter an enclosure in the presence of a potentially dangerous animal.

'All staff members know this.'

Over the next few days, zoo officials will try and calm the cats down by sticking to their usual routine.

This includes checks by keepers in the mornings to make sure the tigers' bodily functions are working well, raw meat feeding sessions once daily and 'enrichment classes' three times a week.

These classes involve hurling a fibreglass ball full of raw meat into the enclosure to encourage the tigers to exercise and to stimulate their brain activity.

The white tiger exhibit is currently closed, and the animals have been restricted to the den area.

If all goes well, the cats will be let out again on Monday, and the exhibit will be reopened, said Mr Guha.

He added that the tigers were not overly aggressive, and had merely shown behaviour that comes naturally to big cats.

In fact, he said, the zoo's tigers are conditioned to the presence of human beings and are likely to be less aggressive around them than their cousins in the wild.

He added: 'It is only when they feel threatened, feel their territory is intruded upon, or view an object as potential prey that they attack. Usually, they would keep away.'

Cleaner's family in shock
He sounded fine when he called home on Wednesday, says sister
Diana Othman & Kimberly Spykerman, Straits Times 15 Nov 08;

SINCE he arrived in Singapore in June, Mr Nordin Montong had called his mother three or four times a day.

He would ask her how the family was and if she had eaten. Little things, just to chat.

It was the same in his last call to her on Wednesday, the night before the 32-year-old cleaner from Sarawak climbed into a tiger enclosure at the Singapore Zoo and was mauled to death after he seemingly baited the big cats.

His family in Kuching is still reeling from the news.

'When we first heard the news, we were shocked and panicked as the last we heard from him, he was healthy and fine,' said his older sister, Madam Nora Montong, 38. 'We did not sense anything was wrong or that he had any problems.'

His 53-year-old mother had become worried on Thursday when her second of six children did not call her as usual.

Said Madam Nora: 'She has been crying now whenever she thinks about him.'

Unable to afford the flight to Singapore, they are awaiting his body, which will be flown home today.

But though his family had no inkling of the turmoil in his mind, his roommates and fellow workers noticed that he was not behaving quite like himself.

Mr Fabian Anak, 26, his colleague of two months who shared a Serangoon apartment with him and other workers, said that the usually jovial man was sombre on Thursday.

He said: 'He hadn't been able to sleep till 3am. He just sat in a chair.'

Another cleaner, Mr Clement Ijau, who lived next door, noticed that Mr Nordin seemed dazed and ignored the people around him.

Fifteen minutes before he went into the enclosure, he reportedly told colleagues they would not be seeing him again.

If he had problems, no one knew. Another colleague, Mr Mohd Rafiq Nasirin, said Mr Nordin was a quiet man who kept matters to himself.

The cleaner from Sarawak had worked at a hotel when he first arrived but left shortly after for a job at the zoo.

Mr Mohd Rafiq said that Mr Nordin had wanted to apply for a transfer to the Night Safari.

According to Madam Nora, her brother had planned to return home in February next year after he had saved enough cash to marry and start a family.

At the mortuary yesterday, Mr Nordin's body - wrapped in a simple white sheet - was received by his employer, Sun City Maintenance, which will bear all costs of embalming and transportation.

Undertaker Roland Tay, 51, will donate his payment of $3,000 to Mr Nordin's family.

They are now bereft of a son and brother as well as any clues which might have accounted for his death.

Madam Nora said: 'We are as confused as everyone. We were not able to be there with him so we could not fathom what he was going through.

'All we can do now is wait for his body to return to Kuching so we can see him again before we bury him.'

Zoo to beef up safety measures
Three steps being considered: alarm buttons, more patrols and CCTV cameras
Jessica Lim, Straits Times 15 Nov 08;

THE Singapore Zoo will be rolling out a series of new security measures to prevent a recurrence of the incident on Thursday, in which a cleaner who jumped into the white tiger enclosure was killed by the big cats.

Three measures are being discussed: Installing alarms in glass housings that the public can set off, deploying more patrols, and setting up closed-circuit television (CCTV) cameras near the exhibits of potentially dangerous animals.

The review of existing procedures was prompted by the death of cleaner Nordin Montong, 32, who managed to get into the enclosure and then provoked the white tigers into attacking him.

If implemented, the new measures aim to ensure a quicker response to similar emergencies.

In Thursday's incident, zoo staff were alerted to Mr Nordin's intrusion when visitors began screaming. They then raised an alarm over walkie-talkies to activate staff to the tiger enclosure. Though about 20 keepers arrived within minutes, they could not prevent the fatal attack.

Yesterday, zoo officials said current measures are sufficient to prevent visitors from getting into serious trouble.

At the white tiger enclosure, for example, thick wooden railings and a plant-bed overhang minimise the chances of a visitor falling into trouble.

The zoo's assistant director, Mr Biswajit Guha, 40, said: 'Even if there is a fall, if the person tries to avoid the tigers, we are confident that we can save him in time.'

What happened on Thursday, he said, was 'an extraordinary situation'.

Another official, Ms Isabel Cheng, the attraction's sales, marketing and communications director, echoed this.

'We cannot account for someone who intentionally scales the railing,' she said.

'We do what we can for careless visitors, but it will be difficult for us to be 100 per cent secure for someone who wants to break into the exhibit.'

She added that there are about 80 staff members patrolling the zoo premises daily, as well as 16 licensed shooters on hand in case of an emergency.

Eight bright green safety boxes full of tools - a gong, a loudhailer, clay balls and a life-preserver ring, among others - are also located across the zoo's grounds.

Keepers hurled some of these items at the white tigers on Thursday in an attempt to distract them from Mr Nordin, with little effect.

Meanwhile, the tragedy has not had an effect on the zoo's popularity.

There was an increase in the number of visitors yesterday. The zoo did not pinpoint the reasons for the rise, but one reason could have been a new exhibit - the 3ha RainForest KidzWorld children's discovery area, which was officially opened yesterday by Temasek Holdings chief executive officer Ho Ching.

Several visitors interviewed by The Straits Times said morbid curiosity was not the reason they were at the zoo.

Some, however, were disappointed that the white tiger enclosure was closed.

Driver Zailani Abdullah, 46, said the extremely rare cats were the main reason he had taken a day's leave to take his two children and wife to the zoo.

He said: 'The tigers are really special with their blue eyes, and my son was looking forward to it.'

Visitors were also unfazed by the attack. Chef Raymond Cheong, who was visiting with his two daughters and niece, said the incident was 'tragic, but a one-off thing'.

Singapore Zoo assures visitors that white tiger exhibit is safe
S. Ramesh, Channel NewsAsia 14 Nov 08;

It held a news conference on Friday to clear any doubts even as it opened its latest S$12 million attraction called the Rainforest Kidzworld.

Visitors streamed in to view the attraction, which opened in time for the school holidays.

Executive director and CEO of Temasek Holdings, Ms Ho Ching, who launched the new attraction, said: "The zoo has deepened its own knowledge and expertise through the years.

"I have full respect for the team at the WildLife Reserves for their hard work, passion and constant care. It is amazing how their dedication and imagination have created a natural and safe wildlife habitat only half an hour away from the city lights."

Meanwhile, the chairperson of Wildlife Reserves - which owns the zoo - took the opportunity to speak about Thursday's incident at the white tiger enclosure.

Claire Chiang, non-executive chairman, Wildlife Reserves, said: "Let me take a few minutes to address the unfortunate incident at the white tiger exhibit yesterday. Our sympathies and condolences go to Mr Nordin Bin Montong's family.

"I would like to reassure all visitors that the white tiger exhibit is very safe and is as safe as any part of the zoo. The safety measures we have implemented exceed the standards recommended by the Association of Zoos and Aquariums (AZA).

"AZA is the internationally recognised organisation that accredits only institutions that have achieved rigorous standards for animal care, education, wildlife conservation and science."

Visitors, too, seemed to agree that the white tiger exhibit does not pose any danger.

Aaron Tan, a visitor, said: "The enclosure is actually quite safe as long as you don't go... into the enclosure itself. So I can still bring my kid here."

At a news conference later, zoo officials addressed other concerns raised, including the five-minute response time it took the sharpshooters to reach the scene.

Biswajit Guha, assistant director, Singapore Zoo, said: "The five-minute situation is essentially sufficient to go to a hotspot in the case of an animal escape. This was an extraordinary situation whereby someone had actually jumped in.

"Even if it had been a fall and the person was trying very hard to avoid the tigers and had gone to the deep end, we are quite confident he would have been able to move in, in time."

He added that firing tranquilisers would not have saved the cleaner as it could have further provoked the animals.

He added: "Tranquilisers don't work instantaneously. So it will take about five minutes before having an impact on the animal. And to have such a sharp impact coming into contact with an animal, it could provoke the animal more and there might be a more drastic reaction."

Meanwhile, the Singapore Zoo said it will not be stationing armed officers at the enclosures which are deemed dangerous. But it will definitely be increasing its patrols by the zoo's keepers and operational staff.

Staff who witnessed the incident or need counselling will also be taken care of.

The zoo hopes to re-open the white tiger attraction within the next few days. - CNA/vm

'Closed', but still they came
Foreign and local visitors flock to closed white tiger exhibit
Hedy Khoo, The New Paper 16 Nov 08;

AMID a backdrop of lush green tranquillity, illuminated by sunlight streaming through the leaves of the overhanging trees, the enclosure was picture perfect.

Except that its star inhabitants - the three white tigers - were nowhere in sight.

A red sign hanging on a wooden gate, which barred access to the viewing gallery of the white tiger enclosure, bore the words 'Exhibit closed. Any inconvenience is regretted'.

It was a stark contrast to the scene only the day before in which horrified visitors screamed and watched helplessly from the viewing gallery as a cleaner who had jumped into the enclosure was mauled to death by the tigers.

The temporary closure of the exhibit was for investigation purposes and to allow the tigers to settle down following the incident, zoo officials said.

But that did not stop local and foreign visitors from stopping by the enclosure of one of the Singapore Zoo's key attractions yesterday.

Some were there hoping to view the extremely rare tigers, others out of curiosity to see for themselves where the incident had taken place. A number were disappointed tourists who were there specifically to see the white tigers.

Though the viewing gallery was closed, the enclosure area was still clearly visible from the sides.

Polytechnic student Gillian Chan, 19, wanted to check how the tigers, her favourite zoo exhibit, were doing after she heard about the incident.

'I am very concerned about the tigers and I hope they won't be put to sleep because it wasn't their fault,' Miss Chan, who visits the zoo almost yearly to see the white tigers, said.

Miss Jolin Chew, 25, a sales co-ordinator, and her friend, Miss Ng Li Xin, 25, a share registrar, had taken leave to visit the zoo.

They had planned their visit a few weeks before and yesterday's incident did not put them off. They headed for the white tiger exhibit first, hoping to see them.

Disappointed

Miss Ng said: 'I don't think the zoo is unsafe just because of the incident as the man jumped into the enclosure on his own.'

One Malaysian family was disappointed.

Mr Lee Hon Leong, 38, who arrived in Singapore with his family yesterday, said: 'We had come all the way from Kuala Lumpur because the white tigers are very rare.'

His crestfallen daughter, 13, and son, 9, had been excited about seeing the tigers.

'Perhaps we will drop by again after six months so that we can see the tigers,' Mr Lee said.

Several tourists from Australia were also disappointed at the closure.

Mrs Leanne Stummer, 40, and her husband were at the zoo for the first time with the main purpose of viewing the tigers because of their rarity.

'We read online that it was one of the main attractions of the zoo here and wanted to see them,' she said.

Although disappointed, she was sympathetic about the tragedy.

'People need to remember that these are wild animals,' she added.

Mr Mike Barnett, 57, and his wife, while disappointed, also understood why the enclosure had to be closed.

'The tigers need time and quiet to settle down after what happened,' he said.

A woman was seen gesturing and discussing in Mandarin with friends how the cleaner could have climbed into the enclosure. She declined to be interviewed.

The zoo opened the Rainforest Kidzworld, a new exhibit targeted at children, yesterday afternoon.

Ms Isabel Cheng, director of sales, marketing and communications, Wildlife Reserves Singapore, said it was not possible to reschedule the event at such late notice.

She said that Thursday's incident was an isolated case.

'The safety of our visitors and employees were not compromised, thus we decided to proceed with the grand opening,' she added.

Groups of kindergarten children trooped past the white tiger enclosure led by their teachers on their way to the Rainforest Kidzworld. Some stopped to look before moving on.

Teacher Chew May Ling, 31, said: 'We had hoped the children could see the tigers, but they are too young to know what happened. We are just here for the opening of Kidzworld.'

Tigers would have been shot if...
The New Paper 16 Nov 08;
CLEANER Nordin Montong's fatal mauling by two white tigers at the Singapore Zoo raised questions about safety. Yesterday, Mr Biswajit Guha, the zoo's assisant director of zoology, and Ms Isabel Cheng, the director of sales, marketing and communications of Wildlife Reserves Singapore, addressed such concerns. ARUL JOHN reports

Mr Biswajit Guha: The shooters' weapons are stored in an armoury, and the shooters have to get the weapons and then go to the scene (the location of the armoury could not be disclosed for security reasons).
16 November 2008

Q: Could the Zoo's licensed shooters have arrived sooner?

Mr Biswajit Guha: The shooters' weapons are stored in an armoury, and the shooters have to get the weapons and then go to the scene (the location of the armoury could not be disclosed for security reasons).

After collecting their weapons, the shooters arrived at the white tiger exhibit within five minutes.

But the tigers were already back in their dens by the time the shooters arrived.

If the tigers could not be lured back to their dens by then, the shooters would have shot and killed the animals.

Q: How far is the armoury from the white tiger enclosure?

Mr Guha: It is slightly less than 800m away. It can be reached within three minutes by running or buggy.

Q: What items are placed in the armoury?

Mr Guha: (Each armoury) contains our weapons and live rounds. The weapons are double-barrelled shotguns and 0.375calibre rifles.

Q: How many licensed shooters does the Zoo have and where are they positioned?

Mr Guha: We have a pool of 16licensed shooters between the Singapore Zoo and Night Safari.

As a standard operating procedure (SOP), upon collection of their arms, the designated officers will go to the front ofthe exhibit where the incident is takingplace.

Q: How many shooters were on duty and where were they positioned?

Mr Guha: At this time, we are not able to check how many out of our 16 licensed shooters were working on 13 Nov. However, on any working day, a minimum of four licensed shooters are on duty.

On 13 Nov, two licensed shooters were activated to collect their weapons. They then positioned themselves at the front of the white tiger exhibit.

Q: Witnesses said that they saw the keepers mainly throwing umbrellas and using a long pole to distract the tigers on Thursday. Could they have been better equipped?

Mr Guha: The keepers also used items from a nearby safety box to distract the tigers. All of the items and more were used to distract the tigets.

These included fire extinguishers, extensible poles, cymbals, loud hailers and clay balls.

Q: Can you tell us your standard operating procedures for handling the various dangerous animals, should a similar incident occur?

Mr Guha: These are confidential internal documents which we are unable to share with external parties.

Q: What happens to the tigers now?

Mr Guha: They are still being looked after and maintained by the Zoo. We have no plans to put them down.

The keepers have been told to keep an eye on them and we want to give them time to recover from the event.

But we are not having extra security measures for the tigers. We think that the white tiger exhibit should be back in action within less than a week.

The tigers are not dangerous to humans. They would not attack humans unless they were taunted, or they thought the humans were prey

Q: Did Mr Nordin have any history of mental illness?

Mr Guha: As far as we know, he was all right when he reported for work on Thursday morning. He was hardworking and there was no indication that he had any mental problems when he was working in the Zoo.

Q: Will the Zoo be reviewing the safety features in the white tiger exhibit and its other dangerous animal enclosures?

Mr Guha: We are looking into the possibility of installing alarm buttons, like those activated by pressing or breaking a glass, near the enclosures so that visitors and/or keepers can raise an alarm more quickly if something happens at these places.

We will increase the frequency of patrols by our keepers and ground staff, especially during lunch time.

The Zoo has 50 keepers and 30 ground staff walking or cycling around its premises daily.

Ms Cheng: The white tiger exhibit is very safe. We have safety features to guard against someone who accidentally falls in the enclosure, like a planter bed below the railing and cable wires that the person can roll onto to prevent him falling into the moat.

In addition, fences on the left and right wings of the exhibit measure 8.5m, inclusive of the water moat wall. The exhibit is permanently surrounded by a water moat 10m wide from the shore to the overhang at the visitors' bridge, and 8.5m from the rock platform to the overhang at the visitors' bridge.

At its deepest, the water is 1.75m deep in the moat.

These enclosure measurements conform to international safety guidelines imposed by the Association of Zoos and Aquariums.

Our lion and polar bear exhibits are also well-protected. But we cannot completely secure against someone who intentionally enters the enclosure.

The incident on Thursday was such a case.

WHY?
Family says he planned to marry next year and talked about holiday in morning call to home
Teh Jen Lee and Tay Shi'an, The New Paper 16 Nov 08;

WITHIN a mere five hours, he snapped. But the trigger that caused Malaysian cleaner Nordin Montong to leap into a tigers' den on Thursday is still elusive.

We now know that he had a pleasant conversation with his family at 7am that fateful day. His sister said he gave no inkling of irrational behaviour or distress.

He had called his mother in Sarawak at 7am, as was his daily routine.

Mr Nordin, the second of six children and the eldest son, would call his family up to four times a day.

On Thursday, he spoke about wanting to return to Sarawak for a holiday in February. And he talked about the weather.

His 52-year-old mother did not suspect anything was amiss. She hung up soon after, thinking that he would call to speak to her again at lunch time.

But that call never came.

At 12.15pm, Mr Nordin, a contract cleaner at the Singapore Zoo, was mauled by two of the three white tigers in their enclosure.

He suffered a fractured skull and multiple bite wounds to his neck, and died soon after.

Zookeepers said Mr Nordin had appeared distressed and had said to them, 'Goodbye, I won't be seeing you again'. He was also seen throwing the contents of his wallet into the crocodile enclosure.

But his close-knit family refuses to believe that something was bothering him. They cannot believe that he deliberately jumped into harm's way.

When they first heard about the incident, their first thought was: Did someone push him into the tigers' enclosure?

In a phone interview with The New Paper from Kuching, Sarawak, his elder sister, Madam Nora Montong, 34, said: 'We don't know what happened. Maybe he got pushed? Maybe he was in a fight? We can't accept it.'

The housewife described her brother as a happy-go-lucky person who recently told them that he had found a girlfriend - his first.

She said in Malay: 'He said he would be back in February and that he was going to get married.'

He first told the family about the girlfriend last month on Hari Raya.

Madam Nora does not know the woman's name, only that she is from Sabah and works in Singapore.

He never mentioned any relationship problems in his frequent calls home.

Madam Nora said that in the four months her brother was in Singapore, he would call daily whenever he was free, taking turns to speak to his parents, siblings, nieces and nephews.

The day before he died, he was speaking to Madam Nora's 6-month-old son on the phone, saying he could not wait to see him.

'He joked with the baby and made cooing noises,' Madam Nora said.

In his Thursday morning call, Mr Nordin spoke to his mother about mundane things like how the weather had been cold recently, and whether she had eaten.

Now, instead of a happy homecoming, the family is preparing to receive his body, which is scheduled to be flown back by his employers, Sun City, this afternoon.

Mr Nordin used to clean at a hotel before being transferred to the zoo, Madam Nora said.

'We were quite worried that he was working with wild animals but he never mentioned tigers. He only talked about the monkeys and chimpanzees. He was assigned to clean those enclosures.'

Madam Nora said her mother was too distraught to be interviewed. Her mother was the last person in the family to speak to him.

'She is very emotional and can't sleep. Of all of us, she was closest to him because he was the eldest son.'

It was Madam Nora's husband who picked up the phone on Thursday and received the bad news from Mr Nordin's agent.

Madam Nora said: 'He was shocked. When he told us, we couldn't believe it.'

Their shock was made worse by the different versions of his death that they heard.

She said: 'The first time, the agent said he fell. We were able to accept that.

'But after that, the agent called again and said there was a video of him jumping. Until we see it, we won't believe it.'

Could it have been because of girlfriend problems?

Madam Nora was emphatic: 'No. When he had trouble, he would think positive. For example, when he had no money, he wouldn't get stressed. He would take the initiative to get help, like ask for money to buy cigarettes.

'He wouldn't see it as a big problem and he would discuss things with us.'

She said her brother worked in construction in his last job in Sarawak, earning RM550 ($230) a month.

Mr Nordin, who studied until Form 2 (Secondary 2), decided to move to Singapore four months ago to earn more money and gain new experiences.

He earned more than $1,000 a month in his job here.

He was a simple man, she said. He did not know how to use money transfers, so he told his family he would bring back his savings when he returned home in February.

Now, the family just wants to know what happened.

Madam Nora repeatedly asked The New Paper if we had a copy of the video, who the eyewitnesses were, and if we could help investigate his death.

She said: 'We all feel very unsatisfied. Where's the proof?

'We don't want people to speak badly of him. I can't think of any reason he would want to end his life.

Breeding of rare birds flying high

Shobana Kesava, Straits Times 15 Nov 08;

UP TO five rare Bali Mynahs could be flown from Singapore to the Indonesian island of their origin early next year.

This will be the largest number of the critically endangered birds to be bred and sent to Bali by the Jurong BirdPark since its programme to reintroduce them into the wild began in 1990.

Three were successfully bred and sent there in 1994.

Unlike the dark plumage of mynahs common in Singapore, Bali Mynahs are a striking white with a cobalt blue band across their eyes.

Their numbers have been decimated by illegal trapping and urbanisation, which have reduced their natural habitat.

The curator of the BirdPark, Dr Minerva Nuqul, said Bali Mynahs have found it harder than other Asian species to adapt to captivity and do not multiply as readily.

'We're on the right track because they are reproducing. If we cannot match the natural environment or the mix of insects and plants they look for in their natural range, they won't breed,' she said.

She was speaking ahead of her presentation at the second Aviary Congress Singapore.

About 45 avian specialists, mainly from Europe and the Asia-Pacific, have converged at the BirdPark to share success stories on breeding rare and wild birds in captivity.

The three-day congress ends today.

The Singapore spotlight is on its success with the crowned pigeon, a native of Papua New Guinea, whose fan of fine feathers on its head distinguishes it from other species.

The blue-grey pigeon, also the largest of the world's species, is threatened in the wild by poachers and hunters. Its success in captivity at the BirdPark is due to a combination of factors: the tropical climate, plenty of foliage and the right diet.

Other successes include the international award-winning work with the rare southern oriental pied hornbill, which has doubled in number on Pulau Ubin to 20 birds since work began in 2004.

Blue-green algae's healing power

Chemist finds compound that works against certain cancer cells
Grace Chua, Straits Times 15 Nov 08;

BLUE-GREEN algae is commonly considered a toxic nuisance, but to Dr Tan Lik Tong, it is a treasure trove of undiscovered medicine.

Dr Tan, a chemist specialising in marine natural products at the National Institute of Education, believes the blue- green algae could be key to the next blockbuster cancer drug.

He has found a compound from it that has toxic properties against breast and leukaemia cancer cells, and is working on accumulating a sufficient quantity for further testing.

Blue-green algae or cyanobacteria is a type of bacteria that produces energy from photosynthesis. The species he studies, Lyngbya majuscula, is common worldwide and can be found at Pulau Hantu.

Often known as fireweed, it can form poisonous algal blooms that smother coral habitats and give fishermen painful welts when they come in contact with them.

The algal blooms are caused by an excess of nutrients from sewage and litter. To prevent their growth, the National Environment Agency monitors cyanobacteria in our reservoirs and beaches. One difference in the cyanobacteria in Singapore is that it does not produce irritant toxins.

No one knows why, or what triggers cyanobacteria to produce toxins, but scientists believe the toxins to be a defence mechanism.

Dr Tan, 40, who obtained his PhD in medicinal and natural products chemistry from Oregon State University, is struck by cyanobacteria's range and variety of compounds. He says: 'It's a treasure trove of compounds.'

He has found at least a dozen chemicals - including six previously unknown to science - from Lyngbya majuscula here, and suspects there are at least 20 to 30 more to be discovered.

Lyngbya majuscula is plentiful in Pulau Hantu's lagoons and tidepools, Dr Tan says. On his annual collecting trips, he just wades into the lagoon at low tide, draws out clumps of the fibrous strands and fills his Nalgene bottles. He can collect up to six full bottles each time.

In his laboratory, individual chemicals are isolated from the algae and tests done to check for possible medical properties.

For instance, Dr Tan's lab found one compound - a cyclic peptide that he calls hantupeptin A, after its source - to be effective against breast cancer and leukaemia cells.

Worldwide, up to seven cyanobacterial compounds are currently undergoing anti-cancer clinical trials. For example, dolastatins are in Phase I and II clinical trials against lung and prostate cancer.

And these are just anti-cancer compounds. Dr Tan also hopes to test the compounds for anti-malarial activity.

Ultimately, he would like to study the effect of hantupeptin A and other compounds on cancer cells.

National University of Singapore marine biologist Chou Loke Ming says Dr Tan's work highlights the local potential for marine drugs, thanks to the region's high marine biodiversity.

'Dr Tan's work emphasises that we don't have to go to exotic places to look for new species to work on,' he says.

'Cyanobacteria occurs in our waters... and it is significant that such a largely-ignored species harbours natural products that have biomedical applications.'

Marina Reservoir: Vital to keep our waterways clean

Straits Times Forum 15 Nov 08;

PUB, the national water agency, thanks Mr Peter Bird for his letter, 'Educate public not to pollute Marina Bay' (Nov 7).

We are heartened that Mr Bird shares our views that the public has a part to play in ensuring that water channelled into Marina Reservoir is clean.

Marina Reservoir is Singapore's 15th reservoir and the first in the city centre collecting water from areas such as Orchard Road, Ang Mo Kio, Bishan and Alexandra.

As Mr Bird has rightly pointed out, soapy water should be drained into the sewerage system, and not into the network of drains and canals which are part of our rainwater collection system. This is especially important for Singapore which has separate networks for the collection of rainwater and used water to ensure that the rainwater collected is not contaminated by used water.

Although advances in technology have enabled us to treat raw reservoir water to drinking water standards, every one of us can still contribute to keeping our catchments clean. To promote greater awareness of the importance of keeping Singapore's waterways clean, PUB has been working closely with various businesses and community groups on several initiatives. For instance, to tackle the problem of silty discharge from construction sites, PUB collaborated with the construction industry on a concerted campaign of public education and engagement, along with technology upgrading and the enforcement of good earth control measures.

PUB's catchment surveillance team visits households and commercial establishments, such as eating houses, to advise premise owners to discharge used water and food waste from washing activities into sewers and not roadside drains.

In addition, we have sewer rehabilitation programmes in place to ensure that the underground sewer system is free of leakages. We have also been actively encouraging individuals and organisations to adopt our waterways and keep them clean, so they learn to treasure and value this precious resource.

With the addition of three new reservoirs, including Marina Reservoir, Singapore's water catchments will increase from half to two-thirds by 2011. We hope all Singaporeans can help keep our catchments and waterways clean so we will have beautiful waterways that everyone can enjoy.

Members of the public can contact us on 1800-284-6600 if they see any pollution to the waterways.

Small but unusual rise in dengue cases in Singapore

Imelda Saad, Channel NewsAsia 14 Nov 08;

SINGAPORE: There has been a small but slightly unusual rise in the number of dengue cases in Singapore.

While incidence of the disease usually starts falling after its seasonal June-September peak, figures this year showed a 14 per cent rise over the same five-week period in September and October last year.

The National Environment Agency (NEA) attributed the rise to a small 0.2 degree Celsius increase in average temperature some 12 weeks ago.

It said warm temperatures have the effect of shortening the life cycle of the Aedes mosquito from seven to 10 days to five to seven days. The virus also replicates faster, resulting in more opportunities for the mosquito to transmit dengue.

NEA also found a 50 per cent rise in the number of breeding sites in homes in the same period over last year.

It identified 15 areas where dengue transmission has increased recently. They include Joo Chiat, Hougang Avenue 8 and Clementi West.

Intensive source reduction operations are being carried out in the affected areas.

NEA said some 20 to 40 per cent more staff have been sent to these areas. It added the cases are mostly sporadic and clusters small in size.

The agency said the best defence against Aedes mosquito-borne diseases is the removal of potential breeding grounds. It said residents should also regularly perform the 10-Minute Mozzie Wipe Out.

Belize reefs and mangroves contribute US$150-196 million

High-Value Assets: Belize's Coral Reefs and Mangroves
WRI website 14 Nov 08;

A new WRI/WWF Central America analysis finds that the coral reefs and mangroves of Belize make a substantial contribution to the country’s economy. Learn more about WRI’s work on Belize coastal ecosystems.

Belize’s coral reefs and mangrove-lined coasts provide critical protection against erosion and wave-induced damages from tropical storms. They have supported artisanal fishing communities for generations and they stand at the center of a vibrant tourism industry, drawing snorkelers, divers and sport fishermen from all over the world.

Despite these benefits, coral reefs and mangroves are frequently overlooked and underappreciated in coastal investment and policy decisions.

Indeed, unchecked coastal development, over-fishing and pressures from tourism threaten the country’s reefs and mangroves. Climate-related changes—such as warming seas, ocean acidification and fiercer storms—could mean that more destruction of coastline ecosystems looms on the horizon.

In a study released today, WRI and WWF Central America evaluate and quantify the economic benefits reefs and mangroves provide to tourism, fisheries and shoreline protection in Belize.

The study looks at only three of the many culturally and economically valuable services provided by these ecosystems in Belize. Nonetheless, even within this narrow scope, these coastal ecosystems clearly provide Belize’s economy with vitally important goods and services.

Coral reef- and mangrove-associated tourism contributed an estimated US$150-196 million to Belize’s economy in 2007, or 12-15 percent of GDP (see chart).

Reefs and mangroves also protect coastal properties from erosion and wave-induced damage, providing an estimated US$231-347 million in avoided damages per year. Additionally, reefs and mangroves provide substantial benefits to the culturally and economically important fishing community, at another US$14-16 million per year.

The full technical report and methodology are coming soon.
Action Needed to Save Belize’s Coastal Ecosystems

Belize’s government, NGOs and private sector are now beginning to recognize the importance of coastal ecosystems to the economy. Nevertheless, the amount currently invested in protecting Belize’s coral reefs and mangroves is very small when compared to the contribution of these resources to the national economy.

Belize’s Marine Protected Area (MPA) system, consisting of 18 protected areas managed primarily by the Fisheries and Forestry Departments along with local NGOs, is widely hailed as an example of forward thinking in marine conservation. The MPAs are an important draw for divers, snorkelers, and sport fishermen, and contain no-fishing areas that help to maintain stocks of key commercial species.

The MPA system is a good first step. However, the system is under-funded, and staff, fuel, and equipment limitations make it difficult to curb illegal fishing and monitor visitation in most of the reserves.

As these coastal and marine resources become increasingly threatened, it is critical to recognize the value they provide and to incorporate this value into policy decision-making.

The Coastal Capital study of Belize finds it is in the long-term economic interest of Belize to:

1) Invest in management, monitoring, and compliance. Greater investments in oversight and management are necessary to protect and preserve Belize’s reefs and mangroves, together with the material benefits they bestow. For instance:

* Reinvigorate the Coastal Zone Management Authority and Institute, whose mission is to support the sustainable use of Belize’s coastal ecosystems, and build capacity for monitoring the state and use of coastal resources.
* Tighten fishing regulations and invest greater resources in enforcement.
* Increase overall investment in MPAs and improve fee collection and monitoring of visitors.
* Build efforts to reduce coral bleaching into the management and expansion of the MPA network.

2) Plan and implement development sensibly. The value of coastal ecosystems must be taken into account when making development policy and management decisions that may adversely affect their health. Here is how they could do so:

* Enforce land-use and development regulations in the coastal zone.
* Minimize the loss of mangroves along the shoreline.
* Conduct and thoroughly evaluate Environmental Impact Assessments and subsequent compliance plans for development in sensitive coastal areas, such as the cayes.

Debate: Which is the world's most invaluable species?

Plankton, bats, primates, fungi and bees - which species would have the greatest impact on our planet if it were lost? Five experts set out their case public debate in London next Thursday

Jessica Aldred, guardian.co.uk 14 Nov 08;

Fungi

'It keeps the trees alive, recycles waste and helps us'
Professor Lynne Boddy of the Cardiff School of Biosciences

Fungi have a bad reputation, usually being thought of as poisoners, rotters of food and homes, causes of plant disease and human infections (eg athlete's foot). In fact, very few fungi cause a nuisance. Moreover, without fungi humans could not exist. Most terrestrial plants obtain their nutrients and water from soil through fungi associated with their roots. Furthermore, fungi are the main garbage disposal agents and nutrient recyclers of the natural world. They are hugely important as food for soil animals and in producing human food, eg Quorn, cheese, chocolate and soft drinks. Fungi produce many "wonder drugs" including penicillin and statins to control cholesterol.

Within this vast kingdom of organisms that is so crucial to our very existence, it is hard to single out just one species. However, my choice would be Amanita muscaria, the fly agaric. This fungus forms mycorrhizas with the roots of forest trees, providing them with water, mineral nutrients, protection from pathogens and some pollutants. It also recycles dead organic matter. It is used as a food source by some animals, and produces powerful chemicals that may turn out to yield novel pharmaceuticals.

Bees
'Bees are irreplaceable. Their loss will be catastrophic'
Dr George McGavin of the Oxford University Museum of Natural History
Honeybee

The partnership between flowering plants and pollinating insects, especially bees, is one of the most widespread and significant symbiotic interactions on Earth. This 100m-year-old collaboration has spawned a rich diversity of species and promoted the rise to dominance of humans.

Now the need to feed our burgeoning population, coupled with the agricultural means to that end – a plethora of pesticides, the unabated loss of natural habitat and the translocation of alien species and diseases - are driving wild and managed bee populations into a very steep decline. Seventy percent of the crop species eaten by humans depend wholly or partly on pollination and recent estimates put the economic value of insect pollination at over £121 billion ($192bn) - representing at least 10% of the value of the world's agricultural production.

Bees are irreplaceable and the debate about what might happen if they disappeared is no longer academic. We have set in motion processes that may lead to the extinction of the planet's most important pollinators along with countless other species that depend on them. Not only will the world be a much less colourful place, it will also be poorer in every other way imaginable. The effects will be nothing short of catastrophic.

Plankton
'Plankton are the base of the whole food web'
Professor David Thomas of the School of Ocean Sciences, University of Bangor
Earthwatch debate: Plankton

Plankton is a collective term for a myriad of bacteria, viruses, plant-like microbes and small animals that drift at the mercy of the winds and the ocean currents and wind. They are the base of the whole food web that lives in just about any body of water you care to imagine: from your bird bath in the garden up to the vast oceans that cover most of the planet.

Temperature extremes hold no bounds and plankton survive being encased in ice in our Arctic and Antarctic oceans and can survive near boiling waters in hot springs. Not only that, but plankton cells can be carried large distance in aerosols in the wind, and some people even believe they can survive in space. They not only fuel aquatic ecosystems, but some release gases that can influence cloud formation and therefore global climate.

But apart from how vital the plankton are to running planet Earth, they are simply beautiful to look at. Plankton have been an inspiration to artists and designers ever since the first microscopes were invented, and plankton inspired design can be found on a whole range of scales from buildings to wheel hubs.

Bats
'Bats provide a number of these essential services'
Dr Kate Jones of the Zoological Society of London
Earthwatch debate: Bats

We are in the midst of a mass extinction of this planet's life brought about by humans monopolising global resources and changing global climate patterns. Many species provide essential services eg, disease control, clean water, pollination and insect regulation, and we are now faced with an agony of choice. Given finite amounts of conservation dollars, which species can we not do without? I present the case for bats.

Bats provide a number of these essential services; for example without bats many commercially important crops such as bananas, mangoes, dates and tequila would fail. Insects consumed by bats translate to millions of dollars saved on pesticides. Bats are also indicators of general ecosystem health and monitoring their populations provides us with early warning systems of irreversible damage.

Bats also have many irreplaceable traits, they are the only mammals to use powered flight, can hunt and navigate in the pitch darkness using only sonic echoes, provide the imagery of Dracula and the flying creatures of Halloween. Perhaps some of us couldn't cope with fewer fungi in our lives, green goo in our rivers, bees to sting and annoy, and primates that one day might rise to overthrow us, but to me a world without bats is unthinkable.

Primates
'Primate habitats provide ecosystem services we all depend upon'
Ian Redmond, chief consultant of the great apes survival project
Earthwatch debate: Gorilla

Monkeys, apes and lemurs must be saved, not just because they share so much DNA with humans (although blood is thicker than water, so this convinces many people), not because they are fascinating research subjects (though clearly they are), not because they are intelligent social mammals who have every right to exist (though arguably they do); not even because primate-watching can form the basis of multimillion-pound tourist industries, creating jobs and lifting rural communities out of poverty.

Any one of these would be reason enough to fight for the survival of our zoological next-of-kin, but I would argue that their ecological role as keystone species in tropical and sub-tropical forests is more important.

Primate habitats provide ecosystem services we all depend upon – especially absorbing carbon while releasing oxygen through photosynthesis and pumping water into the atmosphere through evapo-transpiration, which drives global rainfall patterns. What most people fail to recognise, however, is that primates sow the trees of tomorrow by dispersing seeds in their dung.

If we want these forests to be a permanent carbon store, a source of clean water and to regulate our climate in future, we had better not kill the gardeners of the forest today.

• The Earthwatch debate Irreplaceable - the world's most invaluable species, takes place from 7-9pm at the Royal Geographical Society in London on Thursday November 20.

The animals and plants we cannot live without
From the Amazon rainforests to the frozen ice fields of the arctic, animals, plants and insects are disappearing at alarming rates from pollution, habitat loss, climate change and hunting.

Richard Gray, The Telegraph 15 Nov 08;

Nearly 17,000 species are now considered to be threatened with extinction and 869 species are classed as extinct or extinct in the wild on the International Union for Conservation of Nature's Red List. In the last year alone 183 species became more endangered.

Now, in the face of the growing threat posed by environmental changes around the globe, five leading scientists are to argue whether there is a single type of plant or animal which the planet really cannot afford to lose.

The debate, titled Irreplaceable – The World's Most Invaluable Species, will see five experts present the case for the world's most important animals and plants from a shortlist of five: primates, bats, bees, fungi and plankton.

Primates, which are among the most threatened of animals, are likely to win hearts due to their cuddly exterior while those with a sweet tooth for honey will doubtless sympathise with the bees, which are suffering near catastrophic declines.

Fungi are among the most abundant organisms on the planet and include amongst their numbers the Earth's biggest living organism, a giant fungus known as Armillaria ostoyae which stretches for 2,384 acres in Oregon's Blue Mountains.

Bats are the biggest family of mammals and the only one that can fly, but are threatened by habitat loss and persecution by humans.

Plankton provides food for some of the smallest and biggest animals on the planet, including the Blue Whale.

Here we examine the contenders in detail and asks if we can afford to lose any of them at all.

PRIMATES

Number of different species: 394

Weight: 1 ounce to 440 pounds

Strength in numbers: 400,000 great apes, around a billion other primates

Threats: 114 species are threatened with extinction. Bushmeat hunters and habitat loss are the main threats

PRIMATES are our closest cousins. By studying them and watching their behaviour, humans have been able to gain a remarkable insight into our own beginnings and how our complex cultures have developed.

Primates share more than 90 per cent of our DNA. For Chimpanzees, our closest relatives, the similarities in our genetic code has surprised even the experts.

They are also of great economic importance in many countries – in Rwanda and Uganda the Mountain gorillas are now the number one source of foreign currency income through tourism.

Ian Redmond, chairman of Ape Alliance, an international coalition of organisations and individuals working for the conservation and welfare of apes, said: "Primates are a keystone species in tropical rainforests. They are major dispersers of seeds as they eat fruits and then dispense the seeds in little packets of fertiliser around the forest.

"We need to protect primates today in order to have forests tomorrow that can absorb carbon dioxide from the atmosphere and prevent the erosion of soil."

BATS

Size: 2 grams (0.07 ounces) to 1.5kg (3 pounds)

Number of different species: 1,100

Strength in numbers: billions

Threats: 1 in five species are threatened from habitat loss and persecution

Legends of Dracula and tales of vampire bats have done little to enhance these creatures' reputations. Only one species is the notorious blood sucker, while most feed on insects and fruits.

Bats are the only mammal capable of flying and are so highly evolved to be capable of pinpointing a single insect flying in the pitch black and plucking it out of the air using echo location.

For this reason they are a major predator of insects and play a key role in controlling insect numbers. They are also the most abundant mammal on the planet – one in five mammals is a bat.

"Bats have an extraordinary diversity, which makes them an essential part of the ecosystem," said Dr Kate Jones, a bat expert from the Zoological Society of London. "They are also a key indicator species that can provide information on the health of an ecosystem.

"They occupy a wide range of habitats from urban areas to caves and forests.

"Most crucially, bats are major agents of pollination and seed dispersal. Without them many crops would fail because they play such an essential part of the ecosystem."

BEES

Size: Around half an inch

Number of different species: 20,000 known species of bee

Strength in numbers: Billions of individuals – a single honey bee hive can contain 40,000 bees

Threats: Disease and climate change have seen populations plummet by up to 80%

Without bees, humans would starve. These industrious little insects are the world's greatest pollinators, carrying a dusting of pollen from flower to flower as they gather nectar for their hives. Millions of years of evolution has seen many plants become almost entirely reliant upon bees to help them breed.

Crops such as almonds, peaches, avocados and apricots are totally reliant upon bee pollination.

The total worldwide economic value of pollination has been estimated to be around £130 billion a year, and that is without the honey and wax that bees also produce.

Bee numbers have, however, fallen by up to 80% in some parts of the world due to disease, climate change and pesticide use. The situation has grown so critical that beekeepers are warning there will be no British honey left in the shops by Christmas.

George McGavin, an honorary research associate at Oxford University's Museum of Natural History, said: "The planet could go on functioning quite happily without any large animals such as primates.

"We rely upon bees for just about every vegetable, flower and fruit around. They are a crucial terrestrial group and we would face mass starvation without them."

FUNGI

Size: a single cell to 2,300 acres

Number of different species: Up to 1.5 million

Strength in numbers: millions of billions

Threats: Probably the least threatened group and the cause of threat to many other species in the form of disease

FUNGI are a much maligned group of species. They include pests that can kill gardeners' plants, diseases that are responsible for ailments such as athletes foot and moulds that leave unsightly stains in our houses.

But without fungi we would not have gardens, houses or even feet at all. It was fungi that first allowed plants to move out of the oceans and on to land by establishing a symbiotic relationship that still exists today.

It is a fungi, known as mycorrhiza, that allows plants to obtain nutrients and water from the soil. Rather than directly sucking these essential building blocks of life into its roots, plants have to rely upon the fungi to gather it for them from the surrounding soil.

"It was fungi that allowed plants to move onto land around 600 million years ago," explained Professor Lynn Boddy, a mycologist at the Cardiff School of Biosciences. "Without fungi we would still be living in the ocean."

The other main role that fungi perform is as nature's recyclers. They clean up remains of dead plants and animals by decomposing them and returning the nutrients they hold back to the environment to be used again.

"They are involved in the production of many foods too," added Professor Boddy. "Mushrooms are fungi, but also bread, beer, cheese and chocolate all rely upon fungi to be produced. Many drugs such as penicillin come from fungi too."

PLANKTON

Size: 10 micrometres (0.0004 inches) to 1 millimetre (0.04 inches)

Number of different species: 50,000 in the light zone of the ocean alone

Strength in numbers: Billions of trillions

Threats: Pesticides and pollution can damage plankton blooms

It is hard to feel too attached to plankton. A drifting soup of microscopic algae, creatures and bacteria, they are not even one group of species but bridge entire taxonomic kingdoms. Plankton is essentially anything living in water that is too small to swim against the current, including krill and algae.

But despite its small size, blooms of plankton are visible from space and can sustain billions of marine creatures. The plant-like organisms in plankton, known as phytoplankton, are found close to the surface of the water where there is sufficient light to allow photosynthesis.

"Half of the world's oxygen is produced by these organisms," explained Professor David Thomas, from the school of ocean sciences at the University of Bangor. "If you took that away you would lose the basis of life on the globe. There simply wouldn't be enough oxygen to support life."

The bacteria also provide a vital role by breaking down organic material in the water and recycling dead organisms. The zooplankton, which encompass a wide range of little organisms from single-cell protozoa to creatures such as jellyfish, krill and copepods, provide the basic link in the ocean food chain.

Professor Thomas said: "If you go back far enough in time, life started in the plankton, so we owe it a remarkable debt."

The Irreplaceable debate is being organised by environmental research charity Earthwatch and is being held at the Royal Geographical Society in London on Thursday 20 November. Entry is free and doors open at 6pm.

For tickets and information please call 01865 318856 or email events@earthwatch.org.uk

Giant clams make come back in Philippines thanks to science

Karl Wilson Yahoo News 13 Nov 08;

BOLINAO, Philippines (AFP) – Marine biologist Suzanne Licuanan leans over the side of her battered blue and white motor boat to collect another bag of her precious cargo -- giant clam sperm.

Holding up the bag containing eight litres (14 pints) of the cloudy liquid, she says: "It looks like buko (coconut) juice, doesn't it."

The world's largest shell fish weighing up to 230 kilos (507 pounds) and measuring up to 1.4 metres (4.5 feet) in length, the Tridacna gigas was once a common sight in waters around the Philippine islands.

Highly prized for its meat and decorative shell the giant clam had virtually disappeared from the Philippines, fished out by local and foreign fishermen.

Shocked by the depletion of giant clam stocks marine biologist Edgardo Gomez decided to do something about it.

In 1985 when he was head of what is now the Marine Science Institute of the University of the Philippines he began an ambitious programme to breed and restock the bays and inlets around this southeast Asian archipelago nation of 7,000 islands.

"It really was a shock," he told AFP. "Giant clams are essential to coral reefs and so it was a race against time to build stock up."

Licuanan joined the programme around the same time, when she was a young marine biologist taking a four-year break in 1986 to complete her PhD on giant clams at Australia's James Cook University.

Married to a marine biologist who specialises in coral reefs and with three children she divides her time between her work and being a wife and mother.

On this particular Saturday she was collecting sperm and eggs from clams resting on the seabed off a small island in the Lingayen Gulf, six hours drive northwest of Manila.

Of the 10 known species of clams in the world the Philippines has seven and of that number Licuanan says it is the largest giant clam that is most at risk.

"Saving the giant clam has been a long process that has involved not only breeding and restocking but educating local fishermen that they are worth saving," she says.

"Clams form an integral part of a coral reef's ecosystem. At the same time they can also be farmed as a sustainable livelihood," she added.

Already reefs and bays in many parts of the Philippines are being restocked with mature giant clams from the project's protected ocean nursery areas off Bolinao in the Lingayen Gulf.

"Sometimes you feel like an expectant mother," Licuanan said, tapping a syringe containing serotonin.

"Serotonin is a neurotransmitter that induces the clam to adduct its valves to expel the sperm and eggs," she says. "Sometimes you have to give nature a hand in these things."

Below the boat divers are busy selecting 20 adult clams ranging in age from seven to 10 years, number them and place them in a circle in less than two metres of water.

The thick shells are scrubbed with a nylon brush before the divers return to the boat to collect their syringes and begin to inject the clams.

Within 15 minutes the bivalves start to release clouds of sperm which is collected by the divers in plastic bags and delivered to the boat.

The bags are bought up and less than a litre of sperm is collected in a plastic container bearing each clam's number.

The rest, litres of it, is dumped back into the sea.

Giant clams spawn through an opening known as the excurrent siphon which looks like a miniature volcano on the underside of the clam.

As the clams start to spawn a plastic bag is placed over the outlet to collect the sperm.

Clams number 8 and 13 produce nothing. Then a diver appears calling out: "Eggs from number 8." Then another with: "Eggs from number 13."

"There is a scientific method of mixing sperm to eggs," Licuanan said as she poured the eggs into numbered plastic bags containing sperm.

"We tend to use too little of the sperm according to new data coming to hand."

Within two hours the collection is over and Licuanan is delighted with the day's efforts.

The best part for Licuanan is that the two clams that produced the eggs were young, only eight years old. She says this is close to the transition stage where clams produce both sperm and eggs.

"Clams are male when they are young, enter a transition stage when they are around eight producing eggs and sperm before crossing over and becoming female," she says.

Back at the laboratory peering down a microscope Licunanan estimates they had collected about 16 million fertilised eggs.

"If one percent make it past the hatchery stage you are doing pretty well," she says.

"The last clam spawning in May we managed to get 12 million fertilised eggs (and) from that we now have 200,000 clams in tanks in the hatchery measuring one centimetre in length.

"How many of them will survive the transfer to the ocean nursery where they will be put in cages suspended off the ocean bed we don't know. It's just up to nature."

Rich collection of Costa Rican flora hits the web

Yahoo News 14 Nov 08;

SAN JOSE (AFP) – Costa Rica's National Herbarium announced Thursday it had launched a website with information on 95 percent of the country's plant species -- some 220,000 specimens.

The site collects scientific data on 5,600 types of fungi, 2,000 lichens and tens of thousands of other larger plants and moss, ferns and algae.

The encyclopedic collection is the product of over 120 years of research, said the institute in a statement.

The site represents an "invaluable wealth of information on the biological riches of the country," said the Herbarium, which began collecting and identifying Costa Rican flora in 1887, when the country's National Museum was created.

A key component of the site is the historic collection, which showcases specimens collected and identified between 1887 and 1910.

The 9,624 specimens are of particular interest, and "huge cultural and historical value," said the Herbarium, because they highlight the original flora in areas that are currently under great environmental strain, including deforestation.

Biologist Armando Estrada, from the Herbarium, said the institute's objective was to contribute to the public's knowledge of the country's rich biodiversity, and to promote conservation in the central American nation.

Farne sea birds buck breeding trend

Internationally important colonies of sea birds on the Farne Islands bucked the trend and enjoyed a successful breeding season, according to the National Trust.

Paul Eccleston, The Telegraph 13 Nov 08;

The birds were bolstered by an ample supply of their staple food – sand eels – and managed to raise their young despite poor spring and summer weather.

The islands, two miles off the Northumberland coast between Bamburgh and Seahouses, are looked after by the National Trust (NT) whose wardens collect breeding success data as part of the UK Seabird Monitoring Programme.

They found that in terms of the number of fledged chicks during the 2008 season four of the six key species surveyed on the islands – shags, eider ducks, guillemots and razorbills – had an excellent year.

Further north on the Isle of May and on the Orkney and Shetland islands, which contain a high proportion of British sea birds, there was a poor breeding season, particularly for the kittiwake whose numbers continue to tumble.

The kittiwake population on the Farnes also had a poor year and numbers have dropped to their lowest levels since 1981.

Counts on two of the UK's largest puffin colonies, on the Farnes and Isle of May, had previously shown that numbers are down by about one-third compared to five years ago due apparently to a poor winter survival rate.

On the Farnes there are about 36,500 pairs compared to 55,674 in 2003 but those that did nest enjoyed an 86 per cent success rate.

At the height of the breeding season the Farnes plays host to more than 80,000 pairs of breeding sea birds which include four internationally important species – Arctic terns, sandwich terns, roseate terns and shags – all of whom had an average breeding season.

More than 43,000 people visit the islands every year between April and the end of September to see the wildlife.

David Steel, National Trust head warden on the Farne Islands, said: "Many sea bird colonies have suffered badly this year with the cold spring and wet summer and through a lack of sand eels, the staple food of the seabirds, which can be catastrophic for any seabird colony.

"It's been a reasonably trouble-free summer for the Farne Islands with a good supply of sand eels around the Islands and the seabirds have managed to come through the poor weather conditions."

He added: "The islands witnessed a year-on-year increase in the population of several species but more importantly eider and shag numbers. Both species reported their best breeding seasons in over ten years."

Matt Parsons, coordinator of the UK Seabird Monitoring Programme for the Joint Nature Conservation Committee, said: "Sea birds around the UK had a mixed breeding season in 2008. While European shags bred very successfully, many species fared poorly, especially kittiwakes, Arctic terns, Arctic skuas, guillemots and fulmars."

Japan will not hunt humpback whales this year

Japan officials say that pressure from environmentalists and the governments of Australia and New Zealand means that humpback whales are safe for another year.

Julian Ryall, The Telegraph 14 Nov 08;

The whaling fleet is scheduled to put to sea in a matter of days and has set a target of 850 minke whales and 50 fin whales, according to Shigeki Takaya, a spokesman for the Ministry of Agriculture's Far Seas Fisheries Division.

Last year, Tokyo announced that it would also take 50 humpbacks for the first time since the sixties, provoking outrage from anti-whaling nations. That plan was dropped and plans to hunt the species this year have again been cancelled.

"We received a lot of pressure from around the world, but particularly Australia and New Zealand, so we will not be catching humpbacks as part of the research programme," said Mr. Takaya.

Japan exploits a loophole in the rules of the International Whaling Commission that permits "lethal research." Critics say Tokyo's programme is little more than disguised commercial whaling as the meat ends up in supermarkets and restaurants in Japan.

Mr. Takuya would not reveal the exact date when the whaling fleet will put to sea out of concerns for the safety of their crews.

The radical environmental group Sea Shepherd disrupted last year's hunt and has been widely criticised for threatening the safety of the whalers. On one occasion, environmentalists hurled packages of rancid butter onto the deck of the Nisshin Maru; the Japanese retaliated with flash grenades.

This year, Sea Shepherd has unveiled a new weapon the war against the whalers, with Hollywood mermaid Daryl Hannah - star of the 1984 film "Splash" - scheduled to be aboard the group's flagship, the MV Steve Irwin.

U.S. to Kill Wild Horses as Upkeep Costs Rise?

Maryann Mott, National Geographic News 14 Nov 08;

Thousands of wild mustangs kept in U.S. government holding pens may have to be killed as costs escalate for their upkeep, according to a new federal report released this week.

The report, issued by the Government Accountability Office—the watchdog agency for the U.S. Congress—examined long-term options for successfully managing unadoptable horses.

About 30,000 animals removed from western rangelands are currently being cared for by the U.S. Bureau of Land Management (BLM)'s Wild Horse and Burro Program.

This year, with adoptions dwindling and hay prices rising, holding costs are expected to exceed U.S. $27 million, or about 74 percent of the program's budget.

This level of funding is not enough to control wild populations while keeping older, unadopted animals alive, BLM officials said.

The report comes at a critical time: A decision regarding the fate of thousands of mustangs is expected on Monday when BLM's National Wild Horse and Burro Advisory Board meets in Reno, Nevada.

Slaughterhouse Fear

About 33,000 mustangs, often called wild horses, roam the dusty open plains of ten western states, with about half of the population in Nevada.

With few predators, wild horse herds nearly double every five years. To make room for livestock and farming operations on public lands, government-hired cowboys round up about 10,000 mustangs annually.

Horses are then put into holding facilities to be adopted or sold, or to live out the remainder of their lives. Some animals can live for 15 years in pens.

The 1971 Wild Free Roaming Horses and Burros Act calls wild horses "living symbols of the historic and pioneer spirit of the West."

The legislation ensures that "wild free-roaming horses and burros shall be protected from capture, branding, harassment, or death."

Though the law does allow for euthanasia to achieve "appropriate management levels," public and congressional reaction to the large-scale slaughter of thousands of healthy horses has led the BLM to avoid using these options—despite its recent budget troubles, the GAO report said.

To quell such concerns, Congress gave BLM an alternative to euthanasia in 2004 by allowing the agency to sell horses "without limitation,"—for example at auctions or livestock sales—if the animals have been unsuccessfully offered for adoption three times or are at least ten years of age.

The agency, however, continued to impose sale limitations on buyers, in part, because it feared horses sold for low prices might be resold to slaughterhouses, the report said.

The report also cited job loss as a reason.

"Various BLM officials at different levels of responsibility also told us that the agency has not complied with these provisions," the report said.

Doing so would cause draw negative reaction from the public and Congress and cause an "immediate threat" to the careers of BLM officials involved, it added.

Alternatives

Other alternatives to selling horses exist, the report pointed out.

One would be providing private individuals or organizations with financial incentives, such as tax breaks, to care for unwanted wild horses. (Learn how you can support wild animals through adoptions in Green Guide.)

Another possibility is releasing mustangs on public and private lands outside of areas where they were originally caught, although this would require a legislative change to the horse and burro act.

BLM spokesperson Tom Gorey agreed with the report's findings.

"The GAO report correctly depicts the difficult situation that the BLM finds itself in with regard to maintaining unadopted or unsold animals in holding facilities," he said.

Set Them Free

Horse advocates from around the country are expected to attend the public meeting in Reno in hopes of persuading the agency not to euthanize the horses.

Karen Sussman is president of the International Society for the Protection of Mustangs and Burros.

The nonprofit cares for three wild horse herds in South Dakota, both for conservation and the study of herd dynamics.

Sussman said the BLM caused its own problem by rounding up too many horses in recent years.

Now, to reduce the agency's skyrocketing costs, she suggests sterile horses should be put back on public land to live out the remainder of their lives.

"It would cost nothing to the federal government, and it would resolve the problem."

Europe sits on damning bluefin tuna report

WWF website 14 Nov 08;

Barcelona, Spain: A European fisheries report demonstrating continuing widespread infringements by bluefin tuna fleets despite increased fleet surveillance in the Mediterranean has been delayed until after the conclusion of next week's key international tuna commission meeting to decide on a new management regime for the fishery.

The existence of the report, revealed today by The Economist, undermines Europe's promise of support for strong action possibly including temporary closure of the fishery at the International Commission for the Conservation of Atlantic Tunas (ICCAT) meeting in Marrakech, Morocco.

It also undermines European claims that it is bringing rampant bluefin overfishing under control, with a summary hurriedly produced after repeated demands from the European Parliament noting that extensive consultations with fishers and improved surveillance and inspections had little effect on the low priority industry gave to ICCAT rules.

“After decades of ignoring the science, ICCAT and member states are now trying to outdo each other in rhetoric about how much the science must matter,” said Dr Sergi Tudela, Fisheries director for WWF Mediterranean.

“The information gathered by Europe’s Community Fisheries Control Agency provides unprecedented data on the Mediterranean bluefin tuna fishery that would have been extremely precious for ICCAT scientists to make appropriate management recommendations.

“Shockingly, this valuable information has been kept hidden from scientists, thus undermining the quality of fisheries management advice – and the European Community, representing all EU Members States at ICCAT, must be held responsible for this.”

Earlier this year, WWF welcomed Europe's promise of vastly improved inspection and surveillance of the bluefin fleet and fattening farms by the CFCA, based in Vigo, Spain.

The Economist claims that a comprehensive CFCA report - the product of a €20 million investment in seeking to reign in the bluefin fishery - went to the European Commission in August and that an abbreviated version only was provided to the European Parliament’s Fisheries Commission earlier this month.

The abbreviated version is alarming enough, noting that “the level of apparent infringements detected in the tugs and the purse seiner fleet is considerable”, “the (illegal) use of spotter planes for searching bluefin tuna concentrations is still wide spread” and “as regards the recording and reporting of bluefin tuna catches . . . the ICCAT rules have not been generally respected”.

European Fisheries Commissioner Joe Borg has said that the last management rules for this beleaguered fishery – agreed at a previous ICCAT meeting in Dubrovnik in 2006 – would work, as long as there was compliance with the rules.

“This latest evidence of widespread non-compliance, information that has been hidden from ICCAT scientists and decision-makers, should be case enough that the only solution now is to close the Mediterranean bluefin tuna fishery – pending a complete overhaul of the fiasco,” Dr Tudela said.
