Mitsubishi's all-electric car geared to power up environment-friendly drive in Singapore

Charge ahead with this nippy fella
Christopher Tan, Straits Times 3 Jul 09;

YOU will not hear it coming because it is completely silent. And when you see it, there is little that sets it apart from any other car.

But this is not just any old car: Behold the Mitsubishi i-MiEV, the first production, street-legal all-electric car to arrive in Singapore.

It is not cheap either, with an estimated price tag of a whopping $165,000 - the sticker price for a Mercedes- Benz E-class.

And that is after the green vehicle rebate, mind you.

Mitsubishi dealer Cycle & Carriage is not expecting any buyers, however.

The company brought in the car - unveiled in Japan last month - to take part in Singapore's recently announced $20 million electric vehicle trial.

The three-year trial, led by the Energy Market Authority (EMA), aims to examine the viability and robustness of electric vehicles in a hot, humid place like Singapore. It also aims to gauge the environmental impact of such cars, if any.

The i-MiEV is expected to be joined by other electric models from Nissan and Renault as early as the end of the year.

These might be joined by other models, such as the electric Mini and battery-powered Smart, later.

A spokesman for EMA said: 'We are happy to welcome Mitsubishi to be part of the trial.'

Based on the tiny but roomy Mitsubishi i city car, the i-MiEV is powered by lithium-ion batteries which can be fully charged from a garden variety power socket in about six hours.

If high-voltage fast-chargers, which Singapore's newly formed Electric Vehicle Taskforce will be setting up, are used, the car can be juiced up in 30 minutes.

A full charge is good for about 160km, claims the manufacturer.

However, a spokesman for Cycle & Carriage said that it would realistically do about 120km to 140km with air-conditioners running. But that should still be more than adequate for the average Singapore motorist, who covers 55km a day.

The car's lithium-ion batteries, developed by Lithium Energy Japan - a joint venture between Mitsubishi Motors, GS Yuasa Corp and Mitsubishi Corp - power a lightweight high-tech electric motor.

The car has brake regenerative power, meaning its batteries will be partially charged whenever the brakes are applied.

The i-MiEV's open-market value is estimated at $80,000 - more than six times that of a popular small Toyota.

The batteries and electric drive system are said to be largely responsible for the high cost of the car. Also, since such cars are produced only in small numbers, there are no economies of scale - yet.

Despite the hefty price tag, it is already beginning to look like a winner: Mitsubishi is ramping up production for corporate clients and the local authorities in Japan.

'The benefit is that the car is environmentally friendly,' the Cycle & Carriage spokesman said.

'And a full charge costs only $4. To cover the same distance in a petrol car will cost $30 or so.'

Meanwhile, despite the green attributes of petrol-electric hybrid cars, sales have been crawling. Making their debut in 2001, hybrids on our roads now number only about 2,300 - a mere 0.4 per cent of the total car population.

Newater exceeds quality standards, says expert panel

Amresh Gunasingham, Straits Times 3 Jul 09;

THE quality of Singapore's Newater exceeds standards for drinking water here and around the world, an external audit panel of water experts has found.

The panel, made up of both international and local water experts, put Singapore's own brand of reclaimed water to the test - more than 65,000 tests over six years, to be exact.

The seven experts - from a spectrum of disciplines such as toxicology, engineering and microbiology - were in Singapore for the 12th External Audit Panel Meeting, held in conjunction with the Singapore International Water Week last week.

The experts have met twice a year since November 2003 to perform independent audits and reviews on Newater, desalinated water, PUB tap water and reservoir water.

The panel's chairman, Professor Joan Rose from the Michigan State University's department of fisheries and wildlife, said the audit process has become more stringent over the years.

'Even with additional parameters to be monitored and lower levels of detection through more sensitive instrumentation, Newater still goes beyond the mark in all measures of quality,' she said.

From 190 types of tests conducted on water samples to detect chemical and microbiological parameters a decade ago, there are now 290.

PUB technology director Harry Seah said: 'The yardstick used worldwide to judge the quality of drinking water is around 130 tests. What Singapore has done is to track new emerging threats and constantly add to this.'

The panel has recommended to the PUB that it develop a management strategy to see how Newater can be used in times of emergency or prolonged dry weather.

Newater is now supplied to industries such as those in wafer fabrication, as well as to reservoirs. Under its existing plan, PUB will progressively increase the supply of the high-grade reclaimed water in Singapore's reservoirs to meet about 2.5 per cent of total daily water consumption by 2011.

The unpredictable effects of climate change and weather phenomena such as El Nino - which experts have predicted will strike in the region later this year - could bring prolonged spells of dry weather that affect water supplies, said Prof Rose.

In its report to the PUB, the panel noted that Newater can be used to meet Singapore's water needs 'without limits to its volume'.

It pointed to a rising acceptance worldwide of the use of reclaimed water as countries grapple with issues such as water scarcity and pollution.

Four Newater plants - in Bedok, Kranji, Seletar and Ulu Pandan - have the capacity to meet 15 per cent of Singapore's water needs. This is projected to double in two years' time, with the opening of a fifth Newater plant in Changi.

Thumbs up for NEWater
Channelnews Asia 2 Jul 09;

SINGAPORE: NEWater, Singapore's own brand of high-grade reclaimed water, continues to surpass international quality standards despite more rigorous audit process. This is the unanimous verdict of a panel of international and local water experts, after a week of extensive audit and review.

The so-called External Audit Panel concluded that "NEWater continues to be consistently of high quality and exceeds the Environmental Public Health's (EPH) and United States Environmental Protection Agency's (USEPA) drinking water standards as well as the drinking water guidelines established by the World Health Organisation (WHO) and is therefore, safe as a source of water supply."

The comprehensive sampling and monitoring programme was established in 1999 as part of the R&D for the development of NEWater and has been gradually expanded from 190 physical, chemical and microbiological parameters to more than 290 monitored today.

Professor Joan Rose, chairperson of the panel since its inception, said: "We are very pleased to note that the high quality of NEWater has remained consistent all these years. In tandem with the rapidly evolving water R&D sector, the audit process has become more rigorous over the years.

"Even with additional parameters to be monitored and lower levels of detection through more sensitive instrumentation, NEWater still goes beyond the mark in all measures of quality.

"This demonstrates that the quality of NEWater surpasses international standards, and it also stands up well against the criteria established in Singapore."

Professor Rose is also the Homer Nowlin Chair in Water Research, Department of Fisheries and Wildlife in Michigan State University, USA.

Formed in November 2003, the seven-member External Audit Panel comprises experts from various disciplines ranging from engineering, water chemistry, toxicology and microbiology.

The panel was in Singapore for the 12th External Audit Panel Meeting, which was held in conjunction with the recently-concluded Singapore International Water week.

Because of its ultra-clean quality, NEWater is supplied to high-tech industrial and commercial customers in Singapore, especially those that have high-end processes like wafer fabrication that require water of a higher quality.

In line with international practice, NEWater is mixed with raw water in the reservoirs before undergoing further treatment at the waterworks for supply as drinking water. The existing plan is to progressively increase the amount of NEWater in reservoirs.

Wildlife crisis worse than economic crisis – IUCN

IUCN 2 Jul 09;

Life on Earth is under serious threat, despite the commitment by world leaders to reverse the trend, according to a detailed analysis of the IUCN Red List of Threatened Species™.

The IUCN analysis, which is published every four years, comes just before the deadline governments set themselves to evaluate how successful they were in achieving the 2010 target to reduce biodiversity loss. The IUCN report, Wildlife in a Changing World, shows the 2010 target will not be met.

“When governments take action to reduce biodiversity loss there are some conservation successes, but we are still a long way from reversing the trend,” says Jean-Christophe Vié, Deputy Head of IUCN’s Species Programme and senior editor of the publication. “It’s time to recognize that nature is the largest company on Earth working for the benefit of 100 percent of humankind – and it’s doing it for free. Governments should put as much effort, if not more, into saving nature as they do into saving economic and financial sectors.”

The report analyses 44,838 species on the IUCN Red List and presents results by groups of species, geographical regions, and different habitats, such as marine, freshwater and terrestrial.

It shows 869 species are Extinct or Extinct the Wild and this figure rises to 1,159 if the 290 Critically Endangered species tagged as Possibly Extinct are included. Overall, a minimum of 16,928 species are threatened with extinction. Considering that only 2.7 percent of the 1.8 million described species have been analyzed, this number is a gross underestimate, but it does provide a useful snapshot of what is happening to all forms of life on Earth.

An increased number of freshwater species have now been assessed, giving a better picture of the dire situation they face. In Europe, for example, 38 percent of all fishes are threatened and 28 percent in Eastern Africa. The high degree of connectivity in freshwater systems, allowing pollution or invasive species to spread rapidly, and the development of water resources with scant regard for the species that live in them, are behind the high level of threat.

In the oceans, the picture is similarly bleak. The report shows that a broad range of marine species are experiencing potentially irreversible loss due to over-fishing, climate change, invasive species, coastal development and pollution. At least 17 percent of the 1,045 shark and ray species, 12.4 percent of groupers and six of the seven marine turtle species are threatened with extinction. Most noticeably, 27 percent of the 845 species of reef building corals are threatened, 20 percent are Near Threatened and there is not enough data for 17 percent to be assessed. Marine birds are much more threatened that terrestrial ones with 27.5 percent in danger of extinction, compared with 11.8 percent of terrestrial birds.

“Think of fisheries without fishes, logging without trees, tourism without coral reefs or other wildlife, crops without pollinators,” says Vié. “Imagine the damage to our economies and societies if they were lost. All the plants and animals that make up Earth’s amazing wildlife have a specific role and contribute to essentials like food, medicine, oxygen, pure water, crop pollination, carbon storage and soil fertilization. Economies are utterly dependent on species diversity. We need them all, in large numbers. We quite literally cannot afford to lose them.”

The report shows nearly one third of amphibians, more than one in eight birds and nearly a quarter of mammals are threatened with extinction. For some plant groups, such as conifers and cycads, the situation is even more serious, with 28 percent and 52 percent threatened respectively. For all these groups, habitat destruction, through agriculture, logging and development, is the main threat and occurs worldwide.

In the case of amphibians, the fungal disease chytridiomycosis is seriously affecting an increasing number of species, complicating conservation efforts. For birds, the highest number of threatened species is found in Brazil and Indonesia, but the highest proportion of threatened or extinct birds is found on oceanic islands. Invasive species and hunting are the main threats. For mammals, unsustainable hunting is the greatest threat after habitat loss. This is having a major impact in Asia, where deforestation is also occurring at a very rapid rate.


"The report makes for depressing reading,” says Craig Hilton Taylor, Manager of the IUCN Red List Unit and co-editor. “It tells us that the extinction crisis is as bad, or even worse, than we believed. But it also shows the trends these species are following and is therefore an essential part of decision-making processes. In the run-up to 2010, the global community should use this report wisely to address the situation.”

Climate change is not currently the main threat to wildlife, but this may soon change, according to the report. After examining the biological characteristics of 17,000 species of birds, amphibians and reef building corals, the report found that a significant proportion of species that are currently not threatened with extinction are susceptible to climate change. This includes 30 percent of non-threatened birds, 51 percent of non-threatened corals and 41 percent of non-threatened amphibians, which all have traits that make them susceptible to climate change.

Red List Indices make it possible to track trends of extinction risk in groups of species. New indices have been calculated and provide some interesting results. Birds, mammals, amphibians and corals all show a continuing deterioration, with a particularly rapid decline for corals. Red List Indices have also been calculated for amphibian, mammal and bird species used for food and medicine. The results show that bird and mammal species used for food and medicine are much more threatened. The diminishing availability of these resources has an impact on the health and well-being of the people who depend on them directly.

“The IUCN Red List provides a window on many of the major global issues of our day, including climate change, loss of freshwater ecosystems and over-fishing,” says Simon Stuart, Chair of the IUCN Species Survival Commission and co-editor. “Unless we address the fundamental causes of unsustainability on our planet, the lofty of goals of governments to reduce extinction rates will count for nothing.”

Notes to editors

* In 2002, almost all governments committed to the 2010 biodiversity target “to achieve by 2010 a significant reduction of the current rate of biodiversity loss at the global, regional and national level as a contribution to poverty alleviation and to the benefit of all life on Earth”. The way the 2010 target was phrased highlights the reasons why we should care about nature: its utilitarian value and the fact that it is essential to human wellbeing, but also its intrinsic value (aesthetical, spiritual and recreational).
* Although only 2.7 percent of the world’s 1.8 million described species have been assessed so far, the IUCN Red List provides a useful snapshot of what is happening to species today and highlights the urgent need for conservation action.
* The IUCN Red List has a long established history as the world’s most comprehensive information source on the global conservation status of plant and animal species. It is based on an objective system of assessing the risk of extinction for a species. Species listed as Critically Endangered, Endangered or Vulnerable are collectively described as threatened. The IUCN Red List is not just a register of names and associated threat categories. It is a rich compendium of information on the threats to the species, their ecological requirements, where they live, and information on conservation actions that can be used to reduce or prevent extinctions.
* Wildlife in a changing world consists of a detailed analysis of The IUCN Red List and presents the results by groups of species and biomes (freshwater, marine, terrestrial). It also explains in detail what the Red List really is, how the assessments are conducted, emphasizing the great progress made in recent years to broaden the diversity of species included on the List. One chapter is dedicated to the growing threat represented by climate change. It also includes a section dedicated to the Mediterranean region, a biodiversity hotspot under threat, where our knowledge of biodiversity has greatly increased in recent years.
* Birds are the best known group with less than one percent of species classified as Data Deficient, meaning that we do not have enough information to say if they are threatened or not. However, for many groups, we cannot say what the situation is for a large proportion of species and many of them could well be threatened: 47 percent of 1,045 species of sharks and rays, 35 percent of marine mammals and 24 percent of amphibians are Data Deficient.
* It is not all bad news. Species can recover with concerted conservation efforts. In 2008, 37 improvements in status were recorded for mammals. An estimated 16 bird species avoided extinction over the last 15 years due to conservation programmes. Conservation does work, but to mitigate the extinction crisis much more needs to be done, and quickly. “Conservationists are often considered as alarmists but we need to continue to alert decision-makers to the risk of inaction and the need to give up short term political strategies solely based on economic results,” says Vié. “As shown by the economic and financial crisis, people who raise warning flags should be listened to. Wildlife needs an increased level of attention and our society needs to undertake major changes to safeguard its own future.”

Quote from Partners

BirdLife International “The IUCN Red List is the gold standard for identifying the most urgent conservation priorities, says Stuart Butchart. “This analysis is the most comprehensive published to date, and advances our understanding of the scale and complexity of the current biodiversity crisis, and the actions needed to tackle it.”

Zoological Society of London “Within our lifetime, hundreds of species of birds, mammals and amphibians could be lost as a result of human actions,” says Ben Collen. “Initial studies on the world’s smaller species such as dragonflies, corals and freshwater crabs indicate that threat levels may be similar or even greater. We must set clear goals to reverse these trends and ensure that our enduring legacy is not to wipe out the small things provide us with great benefits such as pollination, nutrient cycling, and climate regulation.”

World 'still losing biodiversity'
BBC News 2 Jul 09;

An unacceptable number of species are still being lost forever despite world leaders pledging action to reverse the trend, a report has warned.

The International Union for the Conservation of Nature (IUCN) says the commitment to reduce biodiversity loss by 2010 will not be met.

It warns that a third of amphibians, a quarter of mammals and one-in-eight birds are threatened with extinction.

The analysis is based on the 44,838 species on the IUCN Red List.

"The report makes for depressing reading," said co-editor Craig Hilton Taylor, manager of the IUCN's Red List Unit.

"It tells us that the extinction crisis is as bad, or even worse than we believed.

"But it also shows the trends these species are following and is therefore an essential part of decision-making processes."

The main policy mechanism to tackle the loss is the Convention for Biological Diversity (CBD), which came into force in 1993 with three main aims:

# To conserve biological diversity
# Use biological diversity in a sustainable fashion
# Share the benefits of biological diversity fairly and equitably

Currently, 168 nations are signatories to the convention, which set the target "to achieve by 2010 a significant reduction of the current rate of biodiversity loss at the global, regional and national level".

Jean-Christophe Vie, deputy head of the IUCN's Species Programme, warned that the scale of "wildlife crisis" was far worse than the current global economic crisis.

"It is time to recognise that nature is the largest company on Earth working for the benefit of 100% of humankind," he said.

"Governments should put as much effort, if not more, into saving nature as they do saving economic and financial sectors.

"When governments take action to reduce biodiversity loss, there are some conservation successes but we are still a long way from reversing that trend."

The assessment lists 869 species as Extinct or Extinct in the Wild. Overall, the report categorises at least 16,928 species as being threatened with extinction.

"All of the plants and animals that make up Earth's amazing wildlife have a specific role and contribute to essentials like food, medicine, oxygen, water," said Mr Vie.

"We need them all, in large numbers. We quite literally cannot afford to lose them."

2010 species pledge set to fail, warns conservation group
Yahoo News 2 Jul 09;

PARIS (AFP) – The world's paramount authority on species loss warned on Thursday that pledges to roll back the threat to biodiversity by 2010 were running into the sand.

The goal set by UN parties under the Convention on Biological Diversity (CBD) to reduce biodiversity loss by 2010 "clearly will not be met," Jean-Christophe Vie of the International Union for Conservation of Nature (IUCN) told AFP.

In its new report, issued on Thursday, the Swiss-based IUCN said Earth was hurtling towards a mass extinction.

Out of 44,838 species on the IUCN's famous "Red List", 869 are considered to be extinct or extinct in the wild, it said.

This tally rises to 1,159 if 290 critically endangered species that are tagged as possibly extinct are included.

Nearly one third of amphibians are at risk of being wiped out through habitat loss, fungal infection and other risks.

More than one in eight birds are threatened with extinction, with Brazil, Indonesia and oceanic islands spearheading the peril. Nearly a quarter of mammals, especially hunted species in Asia, face a similar threat.

"Overall, a minimum of 16,928 species are threatened with extinction," IUCN said in a press release.

"Considering that only 2.7 percent of the 1.8 million described species have been analysed, this number is a gross underestimate, but it does provide a useful snapshot of what is happening to all forms of life on Earth."

The IUCN analysis, Wildlife in a Changing World, was issued just before a deadline governments set themselves to evaluate their success in achieving the 2010 target.

Vie, deputy head of the IUCN's species programme, called on governments to tackle the biodiversity crisis with the same urgency with which they tackled its economic crisis.

"Economies are utterly dependent on species diversity. We need them all, in large numbers. We quite literally cannot afford to lose them."

He added: "Governments should put as much effort, if not more, into saving nature as they do into addressing the economic and financial sectors."

More than 800 wildlife species now extinct
Deborah Zabarenko, Reuters 1 Jul 09;

WASHINGTON (Reuters) - More than 800 animal and plant species have gone extinct in the past five centuries with nearly 17,000 now threatened with extinction, the International Union for Conservation of Nature reported on Thursday.

A detailed analysis of these numbers indicates the international community will fail to meet its 2010 goal of bolstering biodiversity -- maintaining a variety of life forms -- a commitment made by most governments in 2002.

Based on data released in 2008 in the union's Red List, the new IUCN analysis is being released now to precede the 2010 target year and to draw a connection between crises in the financial and environmental realms, said report editor Jean-Christophe Vie.

"We don't want to make a choice between nature and the economy; we just want to bring nature to the same level when you have to take a decision," Vie said by telephone from Switzerland.

"Jobs are important but not jobs to the detriment of nature," he said. "We have done that too much and look where we have arrived."

The new analysis shows 869 species became extinct or extinct in the wild since the year 1500 while 290 more species are considered critically endangered and possibly extinct.

At least 16,928 species are threatened with extinction, including nearly one-third of amphibians, more than one in eight birds and nearly a quarter of mammals.

By comparison, the 2004 Red List showed 784 extinctions since 1500.

PROSPERITY AND BIODIVERSITY

The report said this is not a comprehensive list with only 2.7 percent of the 1.8 million described species analyzed.

The number of extinctions is "a gross underestimate but it does provide a useful snapshot of what is happening to all forms of life on Earth," the study authors wrote.

"It's much more severe than the economic crisis or the bank crisis," Vie said. "You can lose a core industry but you can rebuild one. In nature, if you lose it, you lose it, and you're losing a lot of capital that cannot be replaced."

He said the notion that biodiversity is secondary to economic health is largely a view held by countries in North America, Europe and elsewhere, where the connection to natural products is less direct.

In less developed areas, there is a direct line between human prosperity and biodiversity.

In much of the world, Vie said, "The main problem every day is not to find a job, it's to find food ... and in most places this comes from biodiversity, from nature, from fish and plants."

For land-based species, the main threat is habitat destruction through farming, logging and development.

Climate change is not now the main threat to biodiversity but that could change, the report said.

In examining 17,000 species of birds, amphibians and reef-building corals, the report found a significant proportion that are not now threatened are susceptible to climate change, including 30 percent of birds, 51 percent of corals and 41 percent of amphibians that are not threatened now.

Group: World failing to halt biodiversity decline
Bradley S. Klapper, Associated Press Yahoo News 1 Jul 09;

GENEVA – Governments are failing to stem a rapid decline in biodiversity that is now threatening extinction for almost half the world's coral reef species, a third of amphibians and a quarter of mammals, a leading environmental group warned Thursday.

"Life on Earth is under serious threat," the International Union for Conservation of Nature said in a 155-page report that describes the past five years of a losing battle to protect species, natural habitats and geographical regions from the devastating effects of man.

IUCN, the producer of the world's Red List of endangered animals, analyzed over 44,000 species to test government pledges earlier this decade to halt a global loss in biodiversity by 2010.

That target will not be met, the Gland, Switzerland-based body said, describing the prospects of coral reefs as the most alarming. It also said slightly more amphibians, mammals and birds were in peril compared to five years ago, with species most prized by humans for food or medicine as disproportionately threatened.

"Biodiversity continues to decline and next year no one will dispute that," said Jean-Christophe Vie, the report's senior editor. "It's happening everywhere."

Vie told The Associated Press that biodiversity threats need to be highlighted and combatted, even at a time when many world leaders are preoccupied by economic recession and financial instability. Unlike markets and debts, animal extinction is an irreversible element of today's "wildlife crisis."

He urged governments to usher in major changes to society, such as reducing energy and overall consumption, redesigning cities and reassessing the environmental consequences of globalization — producing goods in one part of the world and sending them thousands of miles to be sold.

Vie said climate change only threatened to make the situation worse.

Governments pledged in 2002 at a meeting of the U.N. Biodiversity Convention and the World Summit on Sustainable Development to halt biodiversity decline by the end of the decade. European governments have set a similar goal among themselves.

In Europe, "about 50 percent of species are under threat or vulnerable," said Barbara Helfferich, a European Union spokeswoman. "Habitats are shrinking and a lot needs to be done. We are doing a lot, but it's not enough as promised to halt biodiversity loss."

Helfferich said a report last year suggested a number of steps for European governments to better protect biodiversity. They included expanding conservation sites, cutting down on overfishing, expanding protection to marine environments and better incorporating ecological concerns in government decisions.

Australia pledges millions for Great Barrier Reef

Yahoo News 2 Jul 09;

SYDNEY (AFP) – Australia on Thursday pledged 52 million dollars (42 million US) to improve water quality on the Great Barrier Reef, which is coming under increasing threat from toxic chemicals and climate change.

Environment Minister Peter Garrett said the money would go to conservation and agriculture groups to help local farmers reduce run-off of pesticides and other chemicals into the World Heritage-listed reef.

"This is the most significant investment any commonwealth government has put into our most important national treasure," said Garrett.

"It does face significant pressures, not the least of which is climate change."

Garrett said scientists, non-government groups and Aboriginal representatives would form an "extraordinary coalition of cooperative interests" to protect the reef.

"It's a very, very important and powerful partnership and we have really high expectations that we can really start to take great care of this important natural asset," he said.

The funding push follows new laws, passed in January, allowing for farmers to be fined if they allow pesticides and fertilisers to run off into the seas around the reef -- described as the world's largest living organism.

Coral growth has slowed markedly on the 345,000-square-kilometre (133,000-square-mile) attraction off Australia's northeast, with scientists blaming raised sea temperatures and higher acidity caused by global warming.

Another endangered elephant dies in Indonesia: WWF

Yahoo News 2 Jul 09;

JAKARTA (AFP) – An elephant calf has starved to death in Indonesia, the eighth endangered Sumatran elephant to have died in the wild since May, environmental group WWF said Thursday.

WWF spokeswoman Syamsidar said the calf was believed to be the offspring of an elephant which was poisoned to death recently in the latest sign of growing conflict between animals and people over land and forest resources.

"A young male elephant died on Wednesday. We suspect it was the offspring of the elephant who recently died because of poisoning," she said.

"It was about two years old and still needed its mother's milk."

The calf was found dead in Sumatra island's Lazuardi forest, Riau province, near a forest concession area owned by a company called Rimba Peranap Indah.

Five of the eight elephants have died near or inside the concession area. Three were killed for their tusks and four were poisoned after eating palm oil plants doused in toxic chemicals.

"Some people are trying to protect their palm oil crops in the area by pouring insecticides on the plants. Maybe it's not intentional but it has killed a few elephants," Syamsidar said.

Conflicts between wild animals and humans are on the rise on Sumatra, where legal and illegal logging is rapidly reducing the tropical jungle.

There are about 2,400 to 2,800 Sumatran elephants in Indonesia, of which 200 to 250 are in Riau, according to WWF.

Bangladeshi man arrested for beating tiger to death

Yahoo News 2 Jul 09;

DHAKA (AFP) – Police in southeastern Bangladesh arrested a man Thursday for beating an endangered Bengal tiger to death after it strayed into a village, a forest official said.

The tiger had entered the village in Satkhira, which is close to the border with India, and residents beat it with sticks because they feared for their lives, the head official for the Sundarbans mangrove forest told AFP.

"The tiger did not kill anyone, but some villagers were afraid so they decided to beat it to death with large sticks," Aboni Kumar Bhushan said, adding that the animal's corpse had been taken away by forest officials for an autopsy.

"Three villagers were injured as they tried to pin the tiger down," he said.

The official said police were preparing to lay charges against the man who was the "ring leader" of the attack, although dozens had helped to kill the animal.

Government figures show 18 people in Bangladesh were killed by tigers in the first six months of this year. All but one of the deaths were in Satkhira district.

Twenty-one people were killed during the whole of 2008, according to another forest official, Mihir Kumar Daw.

Conservationists say tiger-related human deaths are on the rise because a shortage of food in the Sundarbans is forcing them to abandon their traditional territory to look elsewhere for survival.

A cyclone struck the Sundarbans and neighbouring areas on May 26 this year, contaminating fresh water ponds that tigers drink from with salty water.

Forest officials had feared for the survival of the great cats in the area but no deaths were reported.

The Sundarbans, a UNESCO World Heritage Site, lies on the delta of the Ganges, Brahmaputra and Meghna rivers, straddling the border between India and Bangladesh.

The IUCN Red List estimates there are less than 2,500 Bengal tigers left in the world with as few as 200 of those in Bangladesh.

Amur tigers on 'genetic brink'

Matt Walker, BBC News 2 Jul 09;

The world's largest cat, the Amur tiger, is down to an effective wild population of fewer than 35 individuals, new research has found.

Although up to 500 of the big cats actually survive in the wild, the effective population is a measure of their genetic diversity.

That in turn is a good predictor of the Amur tiger's chances of survival.

The results come from the most complete genetic survey yet of wild Amur tigers, the rarest subspecies of tiger.

At the start of the 20th Century, nine subspecies of tiger existed, with a total world population of more than 100,000 individuals.

Human impacts have since caused the extinction of three subspecies, the Javan tiger, Bali tiger and Caspian tiger, and world tiger numbers could now have fallen to fewer than 3000.

The Amur tiger, or Siberian tiger as it is also known, is the largest subspecies which once lived across a large portion of northern China, the Korean peninsula, and the southernmost regions of far east Russia. The Amur tiger most likely derived from the Caspian tiger, recent research has shown.

During the early 20th century, the Amur tiger too was almost driven to extinction, as expanding human settlements, habitat loss and poaching wiped out this biggest of cats from over 90% of its range.

By the 1940s just 20 to 30 individuals survived in the wild.

Since then, a ban on hunting and a remarkable conservation effort have slowly helped the Amur tiger recover. Today, up to 500 are thought to survive in the wild, while 421 cats are kept in captivity.

However, the genetic health of the tiger hasn't improved, according to a new analysis published in Molecular Ecology.

Little variation

Michael Russello and Philippe Henry of the University of British Columbia, in Kelowna, Canada led a team drawn from universities in Canada, Japan and the US in a bid to analyse the genetic profiles of the remaining wild Amur tigers.

They sampled nuclear DNA found within the scat samples of an estimated 95 individuals found throughout the Amur tiger's range, likely constituting up to 20% of the remaining population.

The study sampled the amount of variation within the DNA from more tigers, across a broader geographic, than any previous research.

"Although the census population size of Amur tigers is closer to 500 individuals, the population is behaving as if it were the size of 27 to 35 individuals," says Russello.

That's the lowest genetic diversity ever recorded for a population of wild tigers.

The effective population of any group of animals will be lower than the number that actually exist, due to factors such as non-breeding individuals or a skewed sex ratio.

"However, what is remarkable about the Amur tiger is how much lower the effective population size is than the census size," says Russello.

Population split

Another important finding to emerge from the study is that the remaining Amur tigers are segregated into two populations that rarely intermingle.

The majority of Amur tigers live among the slopes of the Russian Sikhote-Alin Mountains, with 20 or fewer living separately in Southwest Primorye in Russia.

The two groups are separated by a corridor of development between Vladivostok and Ussurisk, and the genetic analysis showed that perhaps just three tigers had managed to cross the divide, reducing the effective size of the wild population further.

"There is little sharing of genes across the development corridor, suggesting that these two populations are fairly discrete," says Russello.

"In actuality, it seems that Amur tigers are residing in two, fairly independent populations on either side of the development corridor between Vladivostok and Ussurisk, further lowering the effective size for each from 26 to 28 for Sikhote-Alin and 2.8 to 11 for Southwest Primorye."

That means more work needs to be done to open up this barrier segregating the tigers.

If that doesn't happen, then it's likely that the Southwest Primorye population will continue to dwindle. That could also kill off the prospect of reintroducing Amur tigers to China, as those in Southwest Primorye are living closest to their former Chinese range.

Captive resource

The news is not all bad for the Amur tiger, however.

Russello and Henry's team also analysed the nuclear and mitochondrial DNA of 20 captive Amur tigers, to see if they retained any unique genetic features since lost by the wild tigers.

"There are gene variants found in captivity that no longer persist in the wild," says Russello, which suggests that the captive program has done a good job of preserving the genetic diversity of the subspecies.

"Now that it is known which individuals possess which gene variants, managers will be able to selectively breed to help preserve the unique and rare gene variants," says Russello.

"The implication is that this variation may be used to re-infuse the wild population sometime in the future if reintroduction strategies are deemed warranted."

Tropical Rainfall Moving North

livescience.com 2 Jul 09;

Earth's most prominent rain band, near the equator, has been moving north at an average rate of almost a mile (1.4 km) a year for three centuries, likely because of a warming world, scientists say.

The band supplies fresh water to almost a billion people and affects climate elsewhere.

If the migration continues, some Pacific islands near the equator that today enjoy abundant rainfall may be starved of freshwater by midcentury or sooner, researchers report in the July issue of the journal Nature Geoscience.

"We're talking about the most prominent rainfall feature on the planet, one that many people depend on as the source of their freshwater because there is no groundwater to speak of where they live," said Julian Sachs, associate professor of oceanography at the University of Washington and lead author of the paper. "In addition many other people who live in the tropics but farther afield from the Pacific could be affected because this band of rain shapes atmospheric circulation patterns throughout the world."

Water shortage?

While water is increasingly becoming a hot commodity around the globe, there is no global water shortage. Human demand for water has tripled in the past 50 years, by some estimates. Yet Earth has essentially as much water now as ever - about 360 quintillion gallons.

Rather, human populations put ever more pressure on local and regional water resources, which in some cases - such as the American Southwest - are dwindling with climate change. The water still exists, it just gets dumped elsewhere.

The band of tropical rainfall is created at what scientists call the intertropical convergence zone. There, just north of the equator, trade winds from the northern and southern hemispheres collide where heat pours into the atmosphere from the tropical sun. Rain clouds up to 30,000 feet thick dump as much as 13 feet (4 meters) of rain a year in some places.

The amount of rain in the zone actually increased between 1979 and 2005, this video shows.

The band is thought to have hugged the equator 350 years ago, during the planet's Little Ice Age (roughly 1400 to 1850).

From dry to downpours

The authors analyzed natural records of rainfall (including microbes and chemical ratios) left in annual layers of lake and lagoon sediments from four Pacific islands at or near the equator.

Washington Island, about 5 degrees north of the equator, is now at the southern edge of the intertropical convergence zone and receives nearly 10 feet (2.9 meters) of rain a year. But during the Little Ice Age it was arid. A similar arid past was found for Palau, which lies about 7 degrees north of the equator and in the heart of the modern convergence zone.

In contrast, the researchers present evidence that the Galapagos Islands, today an arid place on the equator in the Eastern Pacific, had a wet climate during the Little Ice Age.

"If the intertropical convergence zone was 550 kilometers, or 5 degrees, south of its present position as recently as 1630, it must have migrated north at an average rate of 1.4 kilometers - just less than a mile - a year," Sachs said in a statement. "Were that rate to continue, the intertropical convergence zone will be 126 kilometers - or more than 75 miles - north of its current position by the latter part of this century."

The work was funded by the National Science Foundation, National Oceanic and Atmospheric Administration and the Gary Comer Science and Education Foundation.

Plan to kill pelicans in the US hits obstacles

John Miller, Associated Press Yahoo News 1 Jul 09;

BOISE, Idaho – Federal officials have told the Idaho fish and game officials that their plan to halve the number of pelicans nesting in southern and eastern Idaho by 2013 to boost fisheries is an "eradication program" that needs more work.

The Idaho Fish and Game Commission in May approved a five-year plan to kill and haze American white pelicans in southeastern Idaho to protect sport fish and Yellowstone cutthroat trout populations. The plan calls for shooting some pelicans and applying oil to eggs to suffocate the embryos.

Pelicans are protected under federal law, so anything to cut their numbers requires U.S. Fish and Wildlife Service approval.

"We didn't feel the management plan had enough data in it right now to issue the permits required," said Brad Bortner, the Fish and Wildlife Service's migratory birds chief in Portland, Ore. on Wednesday.

Idaho wildlife officials took exception to characterizations of their proposal as a "pelican eradication program" by wildlife officials in Utah

"Absolutely not," said Jeff Gould, chief of Idaho's Bureau of Wildlife. "It's a management plan for pelicans, with the primary goal of reducing impacts to fish."

Gould expects to meet with federal Fish and Wildlife officials later in July to discuss their questions about Idaho's plan, as well as what additional scientific justification will be needed to obtain permits to proceed with management of the big birds.

Pelicans at the Blackfoot Reservoir colony have increased from 1,400 breeding birds in 2002 to 2,400 breeding birds in 2008, while a colony on Lake Walcott on the Snake River increased from about 400 breeding birds in 2002 to more than 4,000 breeding birds.

The agency's plan calls for reducing bird numbers by more than half, while still maintaining a viable population: 700 breeding birds at the Blackfoot Reservoir and 2,100 in Lake Walcott.

Two Fish and Wildlife Service offices — in Oregon and in Utah — panned Idaho's plan, saying that implementing the proposal would undo pelican conservation accomplishments from the last 25 years and any damage could be irreversible.

"Given the conservation status assigned by Idaho and other western states, and given the threats to the species, we believe it is unwise to begin a pelican eradication program," wrote Larry Crist, Fish and Wildlife Service's Utah field supervisor.

"Lethal take of pelicans would not be reversible and it could take years for the local population to recover," he wrote.

Federal managers suggested Idaho instead construct in-stream structures, permanent wire arrays and plant streamside vegetation to discourage pelicans that prey on Yellowstone cutthroat trout, especially in low water years when those swimming upstream are particularly vulnerable.

They also said Idaho's plan failed to take into account how historic water levels in the Blackfoot Reservoir played a role in reducing Yellowstone cutthroat trout numbers. More than 4,700 spawning cutthroats were counted in 2001; the number dropped to just 14 in 2005.

But federal officials pointed out the crash following 2001 came after river discharges during spawning, while trout increased substantially in 2008 after several years of higher river flows.

Pelicans likely arrived in Idaho before white settlers, though the creation of reservoirs for farm irrigation like on the Blackfoot River in the early 1900s produced ideal island habitat for the ground-nesting birds. Some anglers complain the birds eat too many sport fish, though Fish and Game's own plan concedes 90 percent of their diet is composed of non-game fish like chubs.

Idaho can continue to haze pelicans that may be eating cutthroat trout. And for a fourth year, Fish and Wildlife gave state managers permission to kill up to 50 pelicans, though only for scientific analysis of things like their diet, not to control their numbers.

Lebanon's struggling fishermen angling for a catch

Jocelyne Zablit Yahoo News 2 Jul 09;

TYRE, Lebanon (AFP) – Mustapha Shaalan yearns for the days when he would go out to sea and haul in 40 kilograms (88 pounds) of fish in the blink of an eye.

Nowadays, like most fishermen in this southern Lebanese coastal town and elsewhere in the country, he says he is lucky if he reels in one or two kilos on a good day.

Over-fishing, pollution and dynamite fishing have all but wiped out marine life in the Mediterranean waters off the 220-kilometer-long (136-mile-long) Lebanese coast, leaving many of the country's estimated 8,000 fishermen destitute.

"The sea back in the 1960s, 70s and 80s was thick with fish and we were the envy of the town," 68-year-old Shaalan wistfully recalls, sitting on the quay of the picturesque port of Tyre.

"Our reputation extended worldwide," brags the father of seven who began fishing at age 10 and has a deeply creased, suntanned face from years spent at sea. "My pockets were always full and I traveled a lot.

"Now, look at us."

Some 2,000 families live from fishing in Tyre, a city of 100,000 located near the border with Israel, says Khalil Taha, head of the local fishermen's syndicate.

In the city's heyday, a fisherman would easily earn 500 dollars a week, but that figure is now closer to 200 dollars for an entire month, well below the minimum wage of 333 dollars, Taha said.

"The fishermen of Tyre used to do so well that when they would be offered jobs elsewhere they would turn them down," he said. "My father used to earn enough from the trade that he was able to put me and my nine brothers and sisters through private school.

"We used to go and buy our clothes at 'Nouveautes Khater', an upscale department store," added Taha, 49, who has two children and is expecting a third. "Now even the cheapest place is expensive for us."

Taha partly blames the fishermen themselves for their plight but also consecutive governments, which he said have done nothing to protect the fishing industry or help develop it.

Compounding the problem is the constant political turmoil that has rocked Lebanon for years. There was the 1975-1990 civil war, there were Israeli troops in southern Lebanon -- including in Tyre -- between 1982 and 2000 and, most recently, was the devastating 2006 war between Hezbollah and the Jewish state.

"We have been sounding the alarm for more than 10 years about our disastrous situation but no one is listening and I don't think anyone ever will," Taha laments.

Experts say many species, including red mullet, grouper and small barracudas are facing extinction in Lebanon's waters, primarily because of bad fishing practices over the years.

"We are destroying our sea, completely and totally," said Imad Saoud, an aquatic scientist at American University of Beirut. "And the problem is that the people who benefit the most from the sea -- the fishermen -- are the people destroying it the most."

He said the illegal and destructive practice of dynamite or blast fishing, spear fishing and compressor fishing, has irreversibly damaged the marine ecosystem off the coast of Lebanon.

Compressors blow air into crevices or holes at the sea bottom, frightening fish out of their hiding places.

Sewage is also dumped at sea along with heavy metals from factories, including copper, zinc and vanadium -- a metallic chemical.

In addition, greedy developers have been invading the coastline and paying no heed to the environmental impact.

"The state of the Mediterranean in Lebanon is disastrous at all levels and what is coming is even more disastrous," warned Michel Bariche, a marine biologist at American University of Beirut.

"As far as the government is concerned, even if there is a will to do something, they lack the proper know-how," he added. "Even if we scientists draw up solutions, there is no chance they will be implemented."

Bariche said he has been working directly with fishermen to convince them to create marine reserves or protected areas or risk losing their livelihood.

"We need to convince them that these reserves are for their own good, otherwise there will soon be nothing left to fish," he said.

Most of the fish caught in Lebanon comes from Israel and Egypt as drifting larvae, since the currents flow north. Lebanon also imports seafood from Turkey, Egypt and countries in the Gulf region.

Ironically, Taha said, when Israel had its troops stationed in southern Lebanon, there were more fish to catch as fishermen were not allowed to go out to sea at night.

"After the Israelis withdrew, the fishermen went out day and night, leaving no room for the fish to breath," he said. "A fish can't lift its head out of the water here without having 20 fishermen go after it."

Dahej el-Mokdad, head of the department of fisheries and wildlife at the ministry of agriculture, acknowledged that new ground rules are needed on how fishing is conducted in Lebanon but said lack of funds and political bickering has hampered progress.

"We don't have the means to do our job," he said. "We don't even have patrol boats ... and no one considers our sea as a national treasure."

Mokdad said he had submitted a proposal three years ago calling for a new strategy for the fishing industry but it had fallen on deaf ears.

"The fishermen are aware of the gravity of the situation but when they tell you that they have to work to bring in three or six dollars a day to buy bread for their families, what can you do?

"They either starve or go on using illegal practices to fish."

Building a secure future in Bangladesh

BBC News 2 Jul 09;

Bangladesh is the most crowded place on Earth and will become even more impossibly packed in the next 30 years.

Approximately 20% of its land will be lost to the rising waters brought about by climate change.

Today's 150 million Bangladeshis also have to face cyclones and arsenic-contaminated water. About half of the population is illiterate and a third live on less than one US dollar a day.

While others make plans for overpopulation, global warming mitigation and sustainable development, in Bangladesh, it is time for action. And the leadership is coming from within.

BBC presenter Paul Rose has travelled to Bangladesh to meet Nobel Peace Prize winner Muhammad Yunus, the pioneer of micro-credit and visionary of hope for the world's poor.

He will also visit villages, field projects, and schools; and talk to the country's leading innovators to report on life at the "front line of sustainable development".

DAY ONE: SO MUCH WATER, BUT NOT ALWAYS THE RIGHT STUFF

"We must do everything we can to provide enough safe water for every Bangladeshi," says a representative of the environmental services firm, Veolia.

"Climate change has meant that our monsoon is no longer reliable and we are desperately short of water."

In the small village of Goalmari, about a hundred local people gathered to celebrate the opening of the first arsenic water decontamination plant built by Veolia.

It is the result of another successful partnership between Grameen Bank and big business. Professor Yunus set up Grameen Bank in the 1970s to provide financial services for the rural poor.

On the stage, Muhammad Yunus, Grameen Bank officials and local dignitaries all agreed enthusiastically with the opening remarks.

But at the exact moment we all applauded, the heavens opened with the mother of all thunderstorms.

The noise of the heavy rain on the tarpaulins overhead made it almost impossible to hear the presentations. When the fabric began to sag and leak there was a scramble to cover those on stage with umbrellas.

We all moved around to the dry spots, and young lads pushed up on the sags with long poles and drained the water to the sides. Then then the music started.

Girls danced on stage, everyone bopped to the music, while rain poured in through every seam.

There were no dry places now so we took photographs of our wet selves and had lovely laughing conversations with the villagers.

It didn't matter that I speak no Bangla or that their English was limited; we were having a great time.

And the event was worthy of a celebration; The Grameen and Veolia partnership means that these people will now have clean water to drink.

Throughout their lives so far, the only water that has been available to them was contaminated with arsenic.

Traditionally, people here have used rivers and ponds for drinking water. But by the 1970s, the lack of sanitation and water-borne disease was killing an estimated 250,000 children each year.

The solution seemed simple: Tube wells for every village. Millions of wells were sunk and the unlimited cool water and reduction in the child death rate seemed evidence of success.

But no-one had checked to see if the ground water was safe; in fact it contains large amounts of naturally-occurring arsenic.

It took over 20 years before testing of the well water over the border in West Bengal showed that it was contaminated, and that it was poisoning large numbers of people.

Early symptoms of arsenic poisoning include skin blisters and dark blotches. This is followed by internal organ damage and arsenic-induced cancers.

Solving this crisis is a huge task. It will take longer to test all of the tube wells than it took to drill them.

It will take longer still to set up decontamination plants. And even longer than that to communicate the problem to the millions of people who remember the well water as something marvellous that saved them from the surface water diseases.

In the meantime, over 50 million people are still drinking water that is poisoning them.

So we really did have something to celebrate at Goalmari. The innovative partnership of Grameen and Veolia started to save lives from the first batch of clean water.

The music stopped, the final messages of congratulations were sent from those on stage; and the rain stopped immediately. Surely a good omen for the success of this essential project.

Incredible shrinking sheep blamed on climate change

Michael Marshall, New Scientist 2 Jul 09;

Sheep living on a remote island off the coast of Scotland have been shrinking for 20 years. Now it seems shorter winters caused by climate change are responsible.
Soay sheep are a primitive breed of domestic sheep, which live on the island of Hirta, in the St Kilda archipelago, without human interference. From 1955 onwards, the population has been closely studied.

Over the last 20 years, the average size of the sheep has been getting smaller, but it has been unclear why – particularly as natural selection would tend to drive the development of bigger bodies.

Sheep stats

To explore the effects of environmental change and natural selection, Timothy Coulson of Imperial College London and colleagues modified the Price equation, which is used to describe how natural selection changes a population from one generation to the next.

Coulson's team extended the equation so that it could reproduce the effects of a variable environment: how weather and seasons have changed from one year to the next, for example. They also modified it so that they could split the population up into different age groups, and describe changes in them separately.

This modification allowed them to pin down the factors that have affected the size of the sheep.

Natural selection pushes the sheep to get bigger, as the smallest individuals tend not to survive through hard winters to reproduce, they found.

However, this size increase is largely offset by the so-called "young mum effect" – the tendency for female sheep in their first breeding seasons to have offspring that are smaller than they themselves were at birth. The study is the first to take this effect into account.

Dearth of deaths

Over and above these factors, the modelling revealed that one of the most powerful influences on size was the gradual warming of the climate, driven by changes to the North Atlantic Oscillation ocean current, which has led to shorter winters on the island. As a consequence, the vulnerable smaller sheep were more likely to survive the winter, pushing average size down over successive generations.

"Because fewer sheep are dying, I think that means the environment is getting better for them," says Coulson. "The winters are less harsh than they used to be."

Kaustuv Roy, an evolutionary biologist at the University of California San Diego, who was not involved in the study, is impressed. "Their results are really useful, because they tease apart the different processes. It's a really nice study," he says.

Roy adds the team's modification of the Price equation could be used widely. "They've come up with a new approach, which people will definitely apply to other systems," he says.

Climate change is shrinking sheep
Victoria Gill, BBC News 2 Jul 09;

Climate change is causing a breed of wild sheep in Scotland to shrink, according to research.

Scientists say milder winters help smaller sheep to survive, resulting in this "paradoxical decrease in size".

Classic evolutionary theory would predict that wild sheep gradually get bigger, as the stronger, larger animals survive into adulthood and reproduce.

Reporting in Science journal, the team says this shows the "subtle interplay" between evolution and the environment.

Scientists first began studying Soay sheep, on the island of Hirta in the St Kilda archipelago, in 1985.

Since then, the sheep have decreased in size by 5% - their legs getting steadily shorter and their body weight decreasing.

This strange phenomenon was first reported in 2007, but the reason for it remained under debate.

'A natural laboratory'

The lead researcher in the study, Tim Coulson from Imperial College London, said the island provided an ideal opportunity to tease apart the factors driving the sheep's physical change.

"The island is almost like a natural laboratory - there are only the sheep and the vegetation there," he said.

He and his team had access to detailed information about the sheep that had been collected over more than two decades.

"We have so much great data," said Professor Coulson, "that we were able to write a ledger of how much of an effect each of the different factors had on the sheep."

They used a formula called the "Price equation", which was designed by evolutionary theorist George Price to predict how a physical trait, such as body size, will change from one generation to the next.

With all of this data, the team was able to "rearrange the equation" and use it to work out how much of a contribution each driver made to the sheep's body size.

They found that the local environment had a stronger effect on the animals than the evolutionary pressure to grow larger.

"In the past, only the big, healthy sheep and large lambs that had piled on weight in their first summer could survive the harsh winters on Hirta," said Professor Coulson.

Because of climate change, he explained, grass for food is now available for more months of the year on the island.

"Survival conditions are not so challenging - even the slower growing sheep have a chance of making it, and this means smaller individuals are becoming increasingly prevalent in the population," he said.

The team also found that younger sheep tended to give birth to smaller lambs - a phenomenon they termed "the young mum effect".

This effect, said Professor Coulson, combined with environmental changes had "overriden what we would expect through natural selection".

As for the future of the sheep, the team believes that they are still shrinking.

"The next step is to extend our description of past change into a predictive model," said Professor Coulson.

"But it's too early to say if, in 100 years, we will have chihuahuas herding pocket-sized sheep."

Climate change: Bye-bye, black sheep?
Yahoo News 21 Jul 09;

PARIS (AFP) – Another clue has been found in the Case of the Shrinking Sheep, an animal mystery in which climate change features as the principal culprit.

The tale of scientific sleuthing is unfolding on two Scottish islands, Soay and Hirta, in the remote Outer Hebrides.

Their sole inhabitants are wild sheep which probably arrived there with the first human settlers some 4,000 years ago.

The sheep's isolation and lack of predators make them terrific candidates for studying the impact of weather, food and genetics on a wild animal population. The flock, suffering occasional surges and crashes in numbers, has been closely scrutinised since the 1950s.

Two years ago, researchers came across a strange thing: The average size of the Soay sheep was progressively falling.

That finding ran counter to Darwinian intuition. Evolutionary theory said that, given the cold, rough winter on the islands, bigger sheep had the better chance of survival, so their genes should progressively dominate the flock.

The solution to this enigma, suggested Imperial College London scientists earlier this month, lies in global warming.

Milder winters in recent decades have enabled smaller lambs, which otherwise would have died after birth, to survive into adulthood and then reproduce, they said.

The climate whodunnit has now been backed by a trio of Australian experts, who have matched weather and population records with the colour of the sheep's coats.

The smaller sheep that now dominate the flock are also lighter-haired ones, a link that has been proven by gene analysis. Bigger sheep tend to be darker.

Why would coat colour make a difference?

The answer, suggests the team led by University of Western Australia's Shane Maloney, is that, in colder times, sheep with darker coats have an advantage.

Mammals with darker coats absorb more solar radiation and thus need to expend less food energy to keep warm than do their lighter counterparts.

But, as the climate has warmed in the North Atlantic, this advantage has diminished, which gives more of a chance for lighter-haired (and smaller) rivals in the struggle to survive.

"If environmental effects are the cause of the decline, then we can expect the proportion of dark-coloured Soay sheep to decrease further," the fleece police add soberly.

The study appears on Wednesday in Biology Letters, published by the Royal Society, Britain's de-facto academy of sciences.

Plastic Not-So-Fantastic: How the Versatile Material Harms the Environment and Human Health

Jessica A. Knoblauch and Environmental Health News Scientific American 2 Jul 09;

The chemical building blocks that make plastics so versatile are the same components that might harm people and the environment. Greener solutions, however, are becoming available

From cell phones and computers to bicycle helmets and hospital IV bags, plastic has molded society in many ways that make life both easier and safer. But the synthetic material also has left harmful imprints on the environment and perhaps human health, according to a new compilation of articles authored by scientists from around the world.

More than 60 scientists contributed to the new report, which aims to present the first comprehensive review of the impact of plastics on the environment and human health, and offer possible solutions.

“One of the most ubiquitous and long-lasting recent changes to the surface of our planet is the accumulation and fragmentation of plastics,” wrote David Barnes, a lead author and researcher for the British Antarctic Survey. The report was published this month in a theme issue of Philosophical Transactions of The Royal Society B, a scientific journal.

As the scrutiny of the environmental toll of plastic increases, so has its usage, the scientists reported.

Since its mass production began in the 1940s, plastic’s wide range of unique properties has propelled it to an essential status in society. Next year, more than 300 million tons will be produced worldwide. The amount of plastic manufactured in the first ten years of this century will approach the total produced in the entire last century, according to the report.

“Plastics are very long-lived products that could potentially have service over decades, and yet our main use of these lightweight, inexpensive materials are as single-use items that will go to the garbage dump within a year, where they’ll persist for centuries,” Richard Thompson, lead editor of the report, said in an interview.

Evidence is mounting that the chemical building blocks that make plastics so versatile are the same components that might harm people and the environment. And its production and disposal contribute to an array of environmental problems, too. For example:

• Chemicals added to plastics are absorbed by human bodies. Some of these compounds have been found to alter hormones or have other potential human health effects.

• Plastic debris, laced with chemicals and often ingested by marine animals, can injure or poison wildlife.

• Floating plastic waste, which can survive for thousands of years in water, serves as mini transportation devices for invasive species, disrupting habitats.

• Plastic buried deep in landfills can leach harmful chemicals that spread into groundwater.

• Around 4 percent of world oil production is used as a feedstock to make plastics, and a similar amount is consumed as energy in the process.

People are exposed to chemicals from plastic multiple times per day through the air, dust, water, food and use of consumer products.

For example, phthalates are used as plasticizers in the manufacture of vinyl flooring and wall coverings, food packaging and medical devices. Eight out of every ten babies, and nearly all adults, have measurable levels of phthalates in their bodies.

In addition, bisphenol A (BPA), found in polycarbonate bottles and the linings of food and beverage cans, can leach into food and drinks. The U.S. Centers for Disease Control and Prevention reported that 93 percent of people had detectable levels of BPA in their urine.
The report noted that the high exposure of premature infants in neonatal intensive care units to both BPA and phthalates is of “great concern.”

Money flows into green transport despite recession

Colin Barras, New Scientist 2 Jul 09;

A new generation of mean, green electric machines is shifting attitudes to the electric car. Most large automobile companies are pouring money into electric vehicle programmes, and a new report shows venture capitalists are hot on their heels.

Despite the financial recession, venture capital investment in green technology rose, for the first time in six months, during the second quarter of 2009 – and the biggest winner was transport-related technology, according to the report, issued this week by the Cleantech Group and Deloitte.

The problems faced by the traditional automobile industry, particularly companies in the US, are well documented. But for many investors, now is an "historic opportunity" to take a chunk of the market themselves by supporting new clean transportation options, says Brian Fan, senior director of research at Cleantech.
Chock full

Those investors were perhaps buoyed by government initiatives to support green technology, including President Obama's high-profile multi-trillion-dollar budget request for 2010, which was chock full of funding for US science and technology ventures.

Over the past three months, venture capital invested $600 million in green transportation – biofuels, and new vehicle and battery technology. The big winners include V-Vehicles, a San Diego based startup that raised $100 million to build fuel-efficient cars in Louisiana.

Reyer Gerlagh, an economist with a specialism in environmental policy at the University of Manchester in the UK, thinks the new trend is good news. "Venture capitalists not only shape their own future by their self-fulfilling beliefs – they're probably also very influential in shaping other's beliefs," he says.

That's important, because venture capitalists are far too small to make a difference alone. "The amount of funds required to turn our energy system around are beyond the scale of venture capitalists," says Gerlagh.
Solar slump

Andrew Simms, policy director at New Economics Foundation (nef) agrees. "The big technological changes almost never happen without substantial injections of public money," he says. Despite government rhetoric, he thinks the amount spent on green technology is lower than it could be.

The boost in transportation spending is likely a hangover of last year's oil crisis as much as a result of government cash injections, he says. "That sent out a profound message about the need for the next generation technology."

Although green technology was up 12 per cent on the first quarter of 2009, rising to $1.2 billion, that's still 44 per cent down on a year ago – and venture capitalist investment in some areas continues to fall.

Solar power has been particularly badly hit. Investment dropped from £1.2 billion in the third quarter of 2008 to $114 million by the second quarter of 2009.

But Mark Jensen, managing partner of the Venture Capital Services Group at Deloitte, and a co-author of the new study, remains positive. He says solar power investment is down because companies are investing in smaller and less expensive projects – including improvements to solar chips to boost efficiency – rather than focusing on thin-film solar or concentrated solar-thermal technologies.

Spain backtracks on nuclear power phase-out

Yahoo News 2 Jul 09;

MADRID (AFP) – Spain's government said Thursday it would allow the country's oldest nuclear reactor to operate beyond its intended 40-year lifespan, reversing a policy of gradually phasing out nuclear power.

Industry Minister Miguel Sebastian said the Garona plant in northern Spain, which had been designed to function only until 2011 and whose operating permit expires on Sunday, would now be allowed to operate until July 2013.

"This was not an easy decision but it is a thought-out decision," he told a news conference, adding the decision would allow for the preservation of jobs in the region at a time of high unemployment.

Socialist Prime Minister Jose Luis Rodriguez Zapatero had vowed during general elections in 2004 and 2008 to gradually phase out nuclear power when the lifespan of the country's six nuclear plants expired.

He pledged the country would focus instead on the development of renewable energy like solar and wind power.

Greenpeace said Garona has been "suffering from severe cracking and corrosion" and the decision to extend its life "means the continued exposure of the population and the environment to an increased risk of a nuclear accident from this dangerous plant."

"Zapatero?s failure to live up to his electoral promise is also a big step back in Spain?s goal of achieving a sustainable energy model based on 100 percent renewable energy and energy efficiency," Aslihan Tumer, the group's international nuclear campaigner, added in a statement.

Last month Spain's nuclear watchdog recommended that the government renew Garona's licence for another decade, saying the plant could safely operate during that time if certain upkeep works are carried out.

Garona began operating in 1971 in the final years of the right-wing dictatorship of General Franciso Franco and it provides about 1.4 percent of Spain's electricity, according to government figures.

Spain generates around 20 percent of its electricity from nuclear power while in neighbouring France the figure is around 80 percent, the highest proportion of any country in the world.

The country's first nuclear plant in Almonacid de Zorita near Madrid was closed in 2006 and is currently being dismantled.

Earlier Thursday, Zapatero told public radio RNE his government's decision regarding Garona would be "reasonable, reasoned, balanced and responsible" but would be criticised by both sides of the debate over the use of nuclear power.

Support for nuclear energy waned in Europe after the 1986 Chernobyl nuclear power plant accident in Ukraine raised safety concerns over the energy source.

But oil-price volatility and growing concerns over the environmental impact of carbon emissions has led many nations like Britain and Germany to ease their anti-nuclear stance in recent years.

Garona is run by Nuclenor, which is jointly owned by Spain's two biggest utilities, Iberdrola and Endesa.

China blasts US climate bill

Yahoo News 2 Jul 09;

BEIJING (AFP) – China said on Thursday that it was "firmly" opposed to provisions in a new US clean energy bill that will make it easier to impose trade penalties on nations that reject limits to globe-warming pollution.

"China is firmly opposed to such measures," vice foreign minister He Yafei told reporters in Beijing.

"We are firmly against such attempts to advance trade protectionism under the pretext of climate change. It is not conducive to world economic recovery. It serves nobody's interests."

On Friday, the US House of Representatives narrowly passed legislation to limit pollution blamed for global warming, handing President Barack Obama a hard-fought major victory.

Lawmakers voted for the first time in US history to limit heat-trapping carbon emissions and shift the US economy to cleaner energy.

However, after the House of Representatives passed the legislation, Obama said he did not want the bill to be used to impose trade penalties on countries in the interest of curbing global warming, The New York Times reported.

The newspaper said Obama had told reporters at the White House that at a time when the global economy is still deep in recession, he thought "we have to be very careful about sending any protectionist signals out there."

The US Senate has still to vote on the energy bill.

China has shown increasing concern in recent years about the consequences of global warming.

But as part of ongoing global negotiations to replace the Kyoto Protocol when it expires in 2012, China has said the bulk of the responsibility for emissions cuts lies with developed nations.
