Malaysia: 35 orang utan back in the wild

Muguntan Vanar The Star 16 Dec 12;

KOTA KINABALU: Thirty-five orang utans have been rehabilitated at the Shangri-La Rasa Ria Resort's Nature Reserve conservation centre since its inception in 1995.

Sabah Wildlife Department director Datuk Dr Laurentius Ambu said the rehabilitation programme was to complement efforts undertaken by the department's Sepilok Orang Utan Rehabilitation Centre in Sandakan.

“This is also to give an opportunity for the public and schoolchildren from the state's west coast to experience first-hand the rehabilitation process.

“The programme at the resort's nature reserve, however, is much smaller in scale compared to Sepilok,” he said, adding that all 35 rehabilitated orang utans had been returned to Sepilok for release into the wild.

Laurentius was responding to an “open letter” on the reasons they were reluctant to respond to a local NGO Friends of the Orangutans Malaysia regarding the treatment of orphaned orang utans at the Rasa Ria Resort.

Laurentius said the department had always explained the rationale for the initiation of an orang utan rehabilitation centre at the resort in Tuaran, about 35km from here.

He claimed that Friends of the Orangutans Malaysia were invited to attend an orang utan conservation workshop and also for a site inspection of Rasa Ria in November last year but they declined.

There were representatives from other NGOs who came and were happy with the conservation efforts, he added.

“We have nothing to hide. These orang utans only spend their first two parts of the rehabilitation programme at the nature reserve of the resort before being sent back to Sepilok for the last part of their programme.”

He said the Sepilok centre had strictly supervised the rehabilitation programme with a veterinarian on 24-hour call.

Medical checks were also done on all the orang utans in Rasa Ria, he added.

Indonesia: Plant Trees to Prevent Flooding From River

SP/Usmin Jakarta Globe 10 Dec 12;

Bengkulu. Authorities in Bengkulu have highlighted the importance of reforesting denuded river catchment areas in an ongoing effort to prevent flooding during the rainy season.

Sumarsono, the head of the provincial river catchment management agency (BPDAS), said on Saturday that over the past three years his office had planted saplings across 5,000 hectares of affected areas in the Sumatran province.

“We’re doing this to mitigate the impact of the flooding that occurs during the rainy season,” he said.

“We’ll continue to keep regreening critically deforested land in river catchment areas throughout Bengkulu so that we can restore the water-absorbing function of these areas.”

Sumarsono said that when a catchment area lost most of its vegetation, it also lost its ability to absorb high volumes of rainwater runoff. This, he went on, meant that excess amounts of rainfall not absorbed into the ground would keep flowing downhill as floodwater.

He added that planting more trees would also have a beneficial impact beyond the rainy season, with the extra vegetation helping the soil to retain more moisture during the dry season.

He said the BPDAS was working with the provincial military command to reforest critical areas throughout Bengkulu.

In Jambi, meanwhile, the Jawa Pos National Network reported that thousands of hectares of food crop were under threat from ongoing torrential rains that have already caused widespread flooding across the province.

Amrin Aziz, the head of the provincial agriculture office, said on Saturday that much of the farmland under threat lay within the catchment area of the Batanghari River.

“Given the sustained high intensity of the rainfall, thousands of hectares of farmland are at threat,” he said.

He added that many farmers, faced with the prospect of losing their entire harvests, were being forced to harvest their crops early to minimize their losses.

Most of the city of Jambi was paralyzed over the weekend by floodwaters reaching up to two meters in some areas after the Batanghari burst its banks, forcing residents to resort to using rafts and canoes to get around.

Amid Third Week of Floods, Locals Depart
SP/Radesman Saragih & SP/Barthel B. Usin Jakarta Globe 11 Dec 12;

Jambi/Palangkaraya. Facing a third straight week of widespread flooding, residents of Jambi in Sumatra finally began to evacuate their homes on Monday.

Residents living in affected areas along the banks of the Batanghari River had previously refused to leave stilt-supported houses, but with floodwaters now rising as high as three meters, many women and children have begun leaving for higher ground while the men stay behind.

Suhartini, 45, a resident of the Legok ward in the Telanaipura subdistrict, said most of those leaving their homes had opted to go to the homes of relatives rather than to the temporary shelters set up by the authorities.

“It’s only the women and the young children who are going, while the men and the boys are staying put,” she said.

“Someone’s got to keep an eye on the houses so that our property doesn’t get looted while we’re away.”

Since late November, heavy rains have swollen the Batanghari River, raising the water level three meters above normal.

The water level on Monday at Jambi’s Taman Tanggo Rajo floodgate is measured at 13.15 meters, according to officials, up from the normal figure of around nine meters.

Dalmanto, the head of emergency response at the provincial Disaster Mitigation Agency (BPBD), said that if the water level reached 13.45 meters, the flooding there would be considered an emergency situation. “At that point, we would have to order a mandatory evacuation of all residents from the affected areas,” he said.

He added that some parts of Jambi have been inundated for two weeks now and were entering a third week of rising floodwaters.

“The worst-affected area right now is the Legok ward. There are some 264 stilt houses there that are flooded,” Dalmanto said.

“If the water level rises past the critical mark, we’ll have to evacuate roughly 1,370 people from 345 households in that ward alone.”

Rain-induced flooding is also taking a toll on Central Kalimantan, where the Barito and Kahayan rivers have burst their banks.

Aprian Noor, the legislative speaker in the district of North Barito, said on Monday that the district capital of Muara Teweh was now completely paralyzed by flooding, with the water level reaching two meters in some areas.

Bambang Edy Prayitno, the district secretary, said the flooding was the worst in a decade, and added that all residents living on the banks of the Barito River had evacuated their deluged homes while the floodwaters had wrought extensive damage to crops and livestock.

Authorities in Muara Teweh have also begun to register the extent of the damage in the flooded parts of town.

In the Gunung Mas district, the Kahayan River overflowed on Monday, the second time it has occurred since Saturday, cutting off road access into and out of the district.

9,000 Central Kalimantan Homes Inundated as Flood Waters Continue to Flow
Dessy Sagita Jakarta Globe 10 Dec 12;

Nearly 9,000 homes have now been inundated as flooding that began a week ago in Central Kalimantan’s North Barito district continues unabated.

Sutopo Purwo Nugroho, a spokesman for the National Disaster Mitigation Agency (BNPB), said on Sunday that 8,872 homes in the district were reported to have been affected by the flooding.

“The flooding there that began on December 3 is still continuing to spread,” he said. “Six of the nine subdistricts in North Barito are now inundated in around two meters of floodwater. In some places the water is as deep as four meters.”

He added that the problem was so severe that in some areas of the district, the water level was reported to be rising by as much as 30 centimeters a day.

In addition to the houses, the flood has also affected 11 schools, six community health centers, five mosques, a church and a Hindu temple.

The flooding, caused by the rain-swollen Barito River bursting its banks, has also swamped 2,700 hectares of rice paddies and thousands more hectares of other crops, as well as washed out 25 bridges and flooded 10 kilometers of roads.

District authorities declared a state of emergency there on Saturday, while disaster relief officials have set up temporary shelters and soup kitchens to cater to those forced to flee their homes.

Sutopo said relief supplies were being distributed by the district and provincial administrations.

He previously warned that rain-related disasters across the country were expected to continue until January. The BNPB noted that mudslides and floods in the past two months have killed at least 33 people and forced 35,000 to flee their homes.

90-year-old durian tree crushes Ubin kampung house

Two bedrooms in the three-bedroom house were wrecked, but the outdoor kitchen and generator were unaffected
Rennie Whang, Syahirah Anwar The New Paper 15 Dec 12;

SINGAPORE - The house was so special that it was featured in the National Parks Board's walking trail guide to the island.

Taxi driver Azman, 47, said he would take tourists inside if its owner was around.

"I'd say, this is what a kampung house is all about," he said.

But two weeks ago, the 40-year-old Pulau Ubin house was almost completely destroyed as a durian tree, estimated to be 90 years old by residents, fell on it.

Two bedrooms in the three-bedroom house were wrecked, but the outdoor kitchen and generator were unaffected.

Nobody was in at the time, as owner Madam Puasa Ahmad, 78, has mostly stayed on the mainland with a son since her husband died four years ago.

More comfortable

The couple have six children in their 40s and 50s. Up till the Nov 30 incident, said Madam Puasa, she has been visiting once a week, usually alone, to clean the house - which was built by her husband.

"Sometimes I think of the place. It's more comfortable living at the village. You don't have to worry about bills," she said.

"It's old, but holds memories."

Madam Puasa was informed of the accident by her brother-in-law, Mr Ahmad Kassim, 78, whose 50-year-old house overlooks hers.

He said he was praying when he heard a crash at around 6pm.

He went outdoors only to see the house in ruins.

"We're all very sad. There's nothing we can do about it," he said, adding the house was not insured.

Mr Ahmad Kassim said it was the third time he has seen a tree damage a house in all his years on the island. His kitchen was destroyed in 1977, when large branches of another durian tree fell.

He was sleeping in his bedroom at the time.

With the help of other people in the kampung, repair works took just three weeks.

"It's not like now, there are not so many people. If the kampung people were still around, we could each take an axe to the tree and it'd be gone," he said.

The house is on state land and the family is waiting for the tree to be removed by the authorities.

A spokesman for the Singapore Land Authority would only say that it is "aware of the fallen tree and will be removing it."

She continued: "We understand that the tree fell after a heavy storm."

An arborist at DP Green, Mr Edwin Lim, 30, said the stability of the tree trunk could also have been weakened by insects, like borers.

"(The possible decay and presence of borers) and the heavy (winds)... resulting from the current monsoon season are likely the causes of (trunk) failure," he said.

Mr Lim added that unless the trunk showed signs of fungal structures or obvious borer holes, it would be difficult to tell when there will be trunk failure.

Mr Tan Kim Teik, 49, a senior engineer at DPC Consulting Engineers, said rebuilding would most likely involve demolishing the existing foundation.

"Old houses usually don't have good foundations and verification needs to be done if this has eroded."

Framed by coconut trees, the house once made for a pretty picture, said Mr Azman.

Now, it just invites questions as people stop by Mr Ahmad Kassim's to ask what happened.

"A lot of people knew this house," said Mr Ahmad Kassim.

Scientists identify pesky midges

Two different species plaguing Bedok and Pandan reservoirs, but reason for outbreaks still not known
Grace Chua Straits Times 15 Dec 12;

THE researchers studying Bedok Reservoir's midge nuisance have solved a pesky ecological whodunnit.

They now know that two different non-biting species of the tiny insects are the ones responsible for the swarms that have plagued residents around Bedok and Pandan reservoirs for the past couple of years.

But they have not yet worked out the how or why, or how to prevent future outbreaks.

"The first thing you have to know is who's causing the problem, then you can start addressing the issue," said National University of Singapore biologist Rudolf Meier, who is leading a study of the midge problem. The three-year project is part-way through its first year.

The culprit at Pandan is one called Polypedilum nubifer, a common nuisance species that dominates ecosystems almost everywhere it is found.

But at Bedok, the culprit is a fly called Tanytarsus oscillans, a minuscule green species. It has previously been found in Sumatra, India and Japan - but is not known to cause problems anywhere else in the world, said Professor Peter Cranston, the Australia-based midge expert helping with the study.

Identifying the midges is not as simple as looking at stripes or spots, researchers said. It involves staring at the insect's rear end and mouth parts under a microscope to work out whether they really are different from other species.

Prof Cranston said of the Bedok issue: "We don't know what the environmental trigger is yet."

These midges live in the reservoir year-round, but their numbers explode only at the end and beginning of the year. Elsewhere, triggers for a midge swarm can be natural, such as water that goes from flowing to still. Or they can be man-made. For instance, nutrients flow into waterways from deforestation, construction or changing agricultural practices, Prof Cranston said.

But water agency PUB said the water quality in Bedok Reservoir, which is more than 25 years old, is the same as it was before the midge swarms started last year.

Seven ponds in the area collect rainwater from Bedok, Tampines and Tanah Merah, and flow into the reservoir.

Another explanation is that the small fish that feed on midge larvae might have been eaten by larger non-native fish that live in the reservoir.

At Pandan Reservoir, plant roots that dangle from floating wetlands provide a place for these small fish to hide, said PUB biologist Michelle Sim.

Now, the research team breeds midges in the lab and collects data on environmental variables like temperature and water quality to work out possible causes.

Three times a week, the PUB also counts the overall number of midge larvae (of all species) in the water; if it gets above a threshold number, it knows a swarm of adult midges is about to occur.

At Bedok, general preventive measures such as fogging larvicides and scrubbing algae off rocks where midges might lay their eggs are used, and these target all midge species, said Mr Goh Chong Hoon, a deputy director of catchment and waterways at PUB.

In the past few months, there have been only isolated complaints, he said. And he said that currently, there are no warning signs yet of another midge outbreak. "So far, we've been able to keep the numbers low."

Singapore's record on water and built environment provides a lesson for Asia

The tiny island nation proves that good environmental policies – and public-private partnerships – are also good for business
Kishore Mahbubani Guardian Professional 14 Dec 12;

In Southeast Asia, there is an island called Sumatra. On Sumatra there is an extinct volcano. On that extinct volcano, there is a small lake, Lake Toba. In the middle of Lake Toba, there is a tiny island. This tiny island in a volcanic lake is, however, the same size as Singapore.

David Bellamy, the famous British environmentalist, has said that tiny Singapore has more tree species than the continental 48 states of the US. Amitav Ghosh, a famous Indian novelist, echoed this observation: "What is remarkable about Singapore is, despite all the buildings and developments, it remains so green."

This is not a result of accident or good fortune. It is the result of a comprehensive matrix of environmental policies that reinforce each other, providing a model of environmental management that is worth studying in detail.

The world also needs to study it urgently. In 2008, for the first time in human history, more people lived in cities than in rural areas. Urbanisation is accelerating. By 2050, it is estimated that nearly 70% of the world will be urban residents. Of the 25 most densely populated cities in the world, 17 are in Asia, and by 2025, 21 of the world's 37 megacities will be in Asia.

Sadly, few of these cities are managing their environments well. The lessons from Singapore are clearly relevant to Asian megacities. Ghosh says: "A lot of people I interviewed [in 1997] told me, 30 years ago, Singapore was just like Calcutta or Karachi. The transformation of this city in such a short time is a truly stunning thing."

Just look at the water dimension. Projections from the 2030 Water Resources Group suggest that the global gap between water demand and supply could be as large as 40% by 2030.

While the world is running out water, Singapore – which is one of the most densely populated countries in the world – is moving towards water self-sufficiency. Good public policies – including those that preserve water catchment areas, and develop advanced desalination plants as well as plants that utilise modern membrane technology – have led to this success story. This is why the Singapore Public Utilities Board (PUB) won the Stockholm Industry Water Award in 2007.
Private sector dynamism meets public needs

Significantly, many of these projects are provided through public-private partnerships between the PUB and private Singaporean companies, such as Keppel Engineering and SingSpring. The dynamism and innovation of the private sector has been harnessed to help meet public needs.

Singapore's success in environmental management is also influencing its neighbors in Southeast Asia. Kuala Lumpur also began a greening program after watching Singapore's success. The late distinguished former Indonesian foreign minister, Ali Alatas, once told me privately that Jakarta's urban planners used to despair about improving their city. However, after studying how Singapore went from third world to first world in one lifetime, they began to believe that they too could succeed.

And there are other remarkable Southeast Asian success stories. Cambodia is one of the poorest countries in the world, and has experienced the worst genocide of recent times. Yet its capital city, Phnom Penh, has a water authority that expanded the city's water output by 600% in just 10 years. It also manages its water supply better than most British water authorities.

Given Singapore's environmental track record, it is appropriate that it plays host to two global, and increasingly influential, conferences that bring together major stakeholders from the public, private and non-profit sectors: the biennial Singapore International Water Week and World Cities Summit. These two conferences signify the international community's recognition that Singapore's successes in managing the scarcity of space and resources will help many other cities which will experience similar challenges in coming decades, if they are not already experiencing them now.
Eco-city for the future

Singapore is also sharing its experience directly with other cities. The Sino-Singapore Tianjin Eco-city, due for completion in 2020, is one such example. Together, the Singapore and Chinese governments are trying to build a sustainable city for the future, which will serve as a laboratory for the green technologies and public policies that we will need in the 21st century and beyond. Already, more than 600 companies have moved to the Tianjin Eco-city and 4,000 homes have been purchased.

Singapore has also discovered that good environmental policies are good for business. As a result, Singapore is rapidly becoming a hub for the development and manufacturing of sustainable energy sources. Large international firms that specialise in renewable energy – such as Denmark's Vestas Wind Systems and Norway's Renewable Energy Corporation (REC) – have set up shop here. The Solar Energy Research Institute of Singapore (SERIS) is home to 160 leading researchers from across the globe, thanks in large part to a S$130m (£66.1m) government grant, and it collaborates directly with multinational solar companies such as Trina Solar and REC in research and development, as well as personnel training.

These industries are becoming increasingly important to Singapore's economy: by 2015, the cleantech sector is expected to contribute S$3.4bn (£1.7bn) to Singapore's GDP and employ 18,000 people.

In a world that is devoid of good news on the environmental front, Singapore's success provides a lot of hope to many. There is one critical statistic that explains the metaphysical significance of Singapore's success. If the world's seven billion people were to live in a single city as densely populated as Singapore, the entire world would only need an area the combined size of Texas, Oklahoma and Louisiana to live in.

Kishore Mahbubani is dean of the Lee Kuan Yew School of Public Policy at the National University of Singapore, and author of the forthcoming book The Great Convergence: Asia, the West, and the Logic of One World.

Reservoirs can make local flooding worse, says study

Matt McGrath BBC News 14 Dec 12;

Researchers say that large man-made reservoirs can increase the intensity of rainfall and could affect flood defences.

The scientists found that rain patterns around bodies of water in Chile were much higher than in similar areas without them.

This "lake effect" could overwhelm flood defences which are often built without taking it into account.

The study has been accepted for publication in the journal Hydrology.

Stormy edge

Previous research in this field has focused on the impact of dams on local climates. There is evidence that standing bodies like reservoirs and lakes can alter rain patterns by increasing the amount of water that evaporates.

Some experts believe that you also get circulating air patterns in the atmosphere above the boundary between the water and the land and this can initiate thunderstorms and showers.

The impact can be significant. One study showed that extreme precipitation increased by 4% per year after dams were built.

In this latest work, researchers from the University of Talca, Chile, examined data from 50 rain gauges near reservoirs in different parts of the country.

Chile has a large variety of climates ranging from areas that get 0mm of annual rainfall to places that get more that 4,500mm. The scientists found that the most intense rainfall was measured at weather stations located near water bodies, especially in drier climates.

One of the authors, Dr Pablo Garcia-Chevesich from the University of Arizona told BBC News that the work had important implications for flood defences.

"If you install a water reservoir that will change things totally and that will lead to flooding," he said.

"Engineers get fired when there's flooding because they didn't do a good design, but in reality they did good work but someone else installed a water reservoir and the climate changed."

"The bigger the water body, the greater the effect."

Dr Garcia-Chevesich said this area of research was controversial because changing the design of flood defences was very expensive.
Dam boosters

Other scientists took a more measured view of the study.

Dr Faisal Hossain, from Tennessee Technological University, said the Chilean study was purely observational and that while the lake effect changed rainfall patterns, the jury was still out on whether it increased or decreased the amounts.

However, he said that he was hoping to bring the research to the attention of dam builders around the world.

"We have modified the weather patterns in such a way that we didn't anticipate before building these reservoirs, and yes in the global context it might have serious ramifications," he said.

Prof Richard Harding from the UK Centre for Ecology and Hydrology (CEH) said several studies had now pointed to the impact of reservoirs particularly in dry areas.

"The physics says that it will happen, but I'm struggling a little to know how big an impact it is, and quite whether it is strong enough to change the design of flood defences," he said.

Dr Harding suggested that the new study might provide ammunition for those who oppose the building of large-scale new reservoirs.

The authors argue that they want engineers and designers to take this new work into account in planning new flood barriers.

"In the US, they are very rigorous about taking climate change into account when talking about storm water management design," said Dr Garcia-Chevesich, "but this is new and should be taken into account too."

While Singapore is sleeping, this group is sweeping

Charissa Yong Straits Times 14 Dec 12;

IT MAY be 6.30am on a Sunday but the Pang family is up and about, sweeping and picking up other people's litter.

Fund manager Pang Cheng Duan, 49, his wife Theresa Wee and their 11-year-old daughter Sze Ann are armed with brooms and dustpans, hunting down stray pieces of trash at the public carpark outside Eunos MRT station.

They attract curious stares from onlookers and have even been mistaken for offenders doing community service.

The Pangs are part of a group of volunteers from Shinnyo-en Singapore. For nearly 30 years, this religious organisation - a 4,000-strong local chapter of a Buddhist order in Japan - has been cleaning public spaces early in the morning. Every fourth Sunday of the month, between 60 and 100 of its volunteers clean up MRT carparks around the island.

Keeping the environment clean is their contribution to society, said volunteers, including 63-year-old retiree Tan Yen Seng, a litter-picker for 10 years.

Agreeing, entrepreneur Michael Tasrif, 29, said: "As people living in Singapore, we have the responsibility to keep our country clean,"

The group first began cleaning Clifford Pier once a month in 1983. Six years later, it started cleaning the void decks of HDB flats in Farrer Road.

Since 1994, with approval from the National Environment Agency, it has been cleaning the surrounding areas of the Clementi, Ang Mo Kio and Eunos MRT stations, because many of its members were living around there. They keep each session short so as not to get in the way of residents and commuters, said Madam Wee, a 47-year-old housewife.

Public reactions vary. Most people stare, some ask what they are up to, while others thank them for their work.

Madam Wee's daughter Sze Ann, a Tao Nan pupil, said it is a meaningful task and she is happy to do the cleaning. They sometimes collect several bags full of rubbish and salvage recyclables.

Said Madam Wee: "We hope our little effort can go some way towards changing Singaporeans' mindset and attitudes, and that Singapore will one day become a clean city because our people take pride in keeping it clean."

The volunteers, mostly in white shirts with the Shinnyo-en logo, gladly go about their labour despite having to sacrifice sleep each last Sunday of the month.

"I'm not an early bird," admitted civil servant Han Fei Ni, who is in her late 30s. "But it's gradually become a habit I enjoy because it's a good cause."

NTU team invents 'eyes and ears' for underwater vessels

Blind fish inspire creation of sensors that detect changes in water pressure
Feng Zengkun Straits Times 14 Dec 12;

A BREED of blind cave fish has inspired new "eyes and ears" for underwater robots and vessels such as submarines.

The creatures, which are found in the caves of Mexico, rely on a strip of sensitive skin on their sides to detect changes in water pressure caused by predators or obstacles.

Scientists at Nanyang Technological University (NTU) have studied them and come up with similar water pressure-based sensors that could help submarines and underwater robots to navigate their environment.

The new sensors are currently undergoing testing in Singapore waters and could be commercialised within two years.

Currently, underwater robots and vessels usually use sonar sensors or cameras to gather data about their surroundings.

But cameras can be thwarted by murky water, while sonar or soundwave technology is expensive and can harm marine life.

Like the cave fish's organic sensors, the NTU invention relies on water pressure changes to locate and identify obstacles.

When swimmers pass each other, for example, they can feel changes in the water pressure on their skin. The NTU sensors work in the same way.

"To mimic nature, our team created microscopic sensory pillars wrapped in hydrogel," said Associate Professor Miao Jianmin, from NTU's School of Mechanical and Aerospace Engineering.

Each sensor is 1.8mm by 1.8mm. They are clustered in groups of 20, with each cluster costing less than $100 to make. They also require little power, meaning they are cheaper and more environmentally friendly than the conventional sensors.

The NTU invention could also be used for defence, as it can detect nearby submarines without using sonar, which gives away the user's location.

Its only drawback is its limited range, since water-pressure changes weaken with distance. The researchers estimated that vessels equipped with the sensors would detect obstacles only less than one body length away.

NTU is working with the Singapore-MIT Alliance for Research and Technology to outfit autonomous underwater vehicles with the sensors, and will present two papers on the work at a prestigious conference next month.

These craft could be fitted with chemical sensors and used to detect pollution in Singapore's waters.

New slow loris found in Borneo

Matt Walker BBC Nature 13 Dec 12;

A new species of small nocturnal primate has been discovered by scientists in Borneo.

The primate is a type of slow loris, a small cute-looking animal that is more closely related to bushbabies and lemurs than to monkeys or apes.

Uniquely among primates, they have a toxic bite, belying their appearance.

Two previously known subspecies of slow loris have also been accorded full species status.

Details of the discoveries are published in the American Journal of Primatology.

The new species of slow loris, named Nycticebus kayan, has gone unrecognised until now, in part due to its nocturnal lifestyle.

Animals that are active by night often rely less on visual clues, and can therefore appear more similar to one another.

So the scientists had to look hard to discover the differences between the new species.

An international team of researchers, led by Professor Anna Nekaris of Oxford Brookes University in the UK, and Rachel Munds from the University of Missouri in Columbia, US, surveyed slow lorises living in the forests of Borneo and the Philippines.

They focused on studying the primates' facial markings, which take the appearance of a mask, with the eyes being covered by distinct dark patches and the heads by varying patterns.

Part of Prof Nekaris's research was filmed by the BBC programme Natural World, which followed members of the team as they conducted surveys.

This research has revealed there are actually four species of slow loris in the Philippines and Borneo, each with their own, subtly different but distinct head markings.

Originally there was thought to be just a single species, called N. menagensis.

Two of these new species, N. bancanus and N. borneanus, were previously considered subspecies of N. menagensis.

While, N. kayan, is new to science.

"In Borneo in particular, from where three of the new species hail, this will mean that three new lorises will be added as threatened to some degree on the IUCN Red List of threatened species," says Prof Nekaris.

"With more than 40% of the world's primates already threatened with extinction, this brings the toll even higher."

Outside of Borneo and the Philippines, four other slow loris species are known, living across south and southeast Asia.

All have a difficult relationship with humans.

They are the only primates with a toxic bite, secreting the toxin from glands in their elbows.

Slow lorises lick this toxin, and mix it with their saliva. They then use it when they bite, or to coat the fur of their offspring, possibly as a way to deter predators from attacking their young.

The toxin is powerful enough to potentially cause fatal anaphylactic shock in people.

But the slow lorises' cute appearance also makes them a favoured target of the pet trade.

Captured animals often have their canine and incisor teeth pulled out before being sold on as pets, in a bid to protect their potential owner.

Harming the animals this way, though, can quickly lead to their death, as the toothless primates are unable to feed properly.

The discovery that more slow loris species exist also has implications for their survival.

"Well-meaning groups rescue lorises and rarely follow proper guidelines when releasing them back to the wild," says Prof Nekaris.

"That means that the wrong species of loris has found itself in many a new place throughout Asia, if they have survived the traumatising practice of hard release to the wild in the first place."

Video Reveals Rare Tiger Cubs in Sumatran Forest

Douglas Main LiveScience.com Yahoo News 14 Dec 12;

A camera trap caught video of a mother tiger and her two cubs in a protected Sumatran forest, the first evidence of breeding in this location, conservationists say.

The footage was captured in Sumatra's Sembilang National Park. Scientists from the Zoological Society of London (ZSL) have documented evidence before of the endangered species in nearby Berbak National Park.

The video of these big cats shows the mother and her two youngsters walking past the camera. Scientists said they estimate the cubs are less than a year old, according to a ZSL release.

"This is the best early Christmas present, and we are absolutely delighted to find the first evidence of breeding in Sembilang," said Sarah Christie, ZSL head of regional conservation programs, in a statement. "We will continue working with leaders of both national parks as well as the government to ensure the areas are better protected and well patrolled."

The finding gives scientists some hope; there are only 300 Sumatran tigers, the smallest of the tiger species, estimated to be in the wild, according to the release. Camera traps have also caught video of tapirs and sunbears in the nearby Berbak forest.

Sembilang and Berbak National Park are some of the only places in the world where these tigers remain, according to the release.
