Kampar peat bog

(c) New Scientist

The bog barons: Indonesia's carbon catastrophe
01 December 2007
Fred Pearce

"Until five years ago, Kampar was a true bog with water at the surface, and it was covered by a rich rainforest ...

"Next week, the world's governments will assemble on the Indonesian island of Bali to discuss what should follow Kyoto. The fate of peatlands like Kampar will be an important topic. The Indonesian government is expected to argue that the very companies destroying the bogs should be awarded carbon credits for stopping the haemorrhaging of even more carbon. But can the region's great despoilers really become its saviours?"

"With or without fires, the draining of peatlands is causing massive emissions of CO2.

"The critical process here is oxidation. As long as peat stays wet, the acidity and lack of oxygen preserve organic matter, allowing the peat to build up. But when water levels fall and the peat begins to dry, the organic matter starts to break down. The loss of forest accelerates the process by exposing bare peat to the tropical sun. Emissions continue until any peat above the water table is gone.

"Where water is drained to a depth of a metre, typical for many palm oil plantations, about 10 centimetres of peat disappears every year. This emits between 130 and 180 tonnes of CO2 per hectare each year."

"The next steps to resolving Kampar's future could come during the upcoming negotiations in Bali. At the conference, Indonesia is planning to make the case that any successor to the Kyoto protocol should reward countries in the developing world with carbon credits for avoiding carbon losses from deforestation and drained peatlands."

Mauve Stinger offshore

Killer jellyfish salmon attack carries £1m sting in tail
[Pelagia noctiluca]

Swarm wipes out organic farm

Thursday, November 22, 2007

By Lesley-Anne Henry and Deric Henderson

The owners of Ulster's only salmon farm have said it may take two years to recover after billions of tiny jellyfish wiped out more than 100,000 salmon, causing damage over £1m.

The Department of Agriculture and Rural Development Minister, Michelle Gildernew, has been called in to devise a financial package to save the Glenarm Organic Salmon Company.

Last week's invasion of Mauve Stingers at Glenarm Bay and Red Bay, Cushendun, off the Co Antrim coast, lasted for nearly seven hours with the jellyfish covering a sea area of up to 10 square miles and 35 feet deep.

The Mauve Stingers, which can grow up to 10cm in diameter, stung and stressed the salmon which were being kept in cages about a mile out into the Irish Sea. The fish died of their injuries and the trauma of the attack.

At one stage staff in three boats tried to reach the cages, but such was the density of the jellyfish they struggled to get through before it was too late.

It could take at least two years for the owners to recover from the setback and the firm's future was in doubt.

"We are still assessing the full extent, but it's a disaster," said John Russell, managing director of Northern Salmon Company.

Mr Russell described last week's attack as unprecedented.

He said: "In 30 years, I've never seen anything like it. It was unprecedented, absolutely amazing. The sea was red with these jelly fish and there was nothing we could do about, it, absolutely nothing.

"It's touch and go if we can survive this. Our salmon is a premier product which fronts up the seafood industry in Northern Ireland and everything must be done to protect it. It's really important for the seafood industry that we get up and going again, because we've taken a huge financial hit. We need to keep this operation going and in order to do so we need financial aid."

Mr Russell from Fort William, Scotland, who took over as the company's new MD just three days before the attack, said: "I have never experienced such concentrations of jellyfish spread over such a wide area. The vastness was unbelievable.

"You cannot legislate for something like this."

Fish from Glenarm is sold to some of London's leading restaurants. The Queen had salmon cooked for her on her 80th birthday last year. It was also exported to France, Belgium, Germany and the United States.

Mauve Stingers are normally found in warmer waters.

Christine Maggs, Professor of Marine Biology at Queen's University in Belfast said the species is well-known for its population fluctuations which peak almost every 10 years.

"I would say this is the peak of the cycle," she told Radio Ulster.

Natural England

Natural England defends wildlife and beautiful places but has had a torrid first year.

Peter Marren reports on the government body that was set up to improve conservation but faces budget cuts and internal dissent

(c) The Guardian
7th November 2007

Nobody is suggesting that it has been an easy first 12 months for the government body that "works for people, places and nature". There are high expectations that Natural England (NE) - formed a year ago by the merger of English Nature, the Countryside Agency and the part of the Department for Environment, Food and Rural Affairs (Defra) concerned with environmental payments - will become rather more than the sum of its parts. Government expects benefits from efficiency and savings, and it also wants a strong, confident agency where nature, access and sustainable land use are key to a cleaner, greener future.

At its birthday party nine days ago, NE's chief executive, Helen Phillips, counted the early achievements. It has won a measure of agreement from all sides for the government's plan to extend public access to all parts of the English coastline, citing the project as a working example of the "holistic" approach with advantages for access, landscape and wildlife.

Another fresh idea is "green infrastructure"....

IUCN Bear Groups

http://www.iucn.org/en/news/archive/2007/11/12_pr_bear.htm

Seventy-five percent of bear species threatened with extinction

Six out of the world’s eight species of bears are threatened with extinction, according to recent assessments by the IUCN Bear and Polar Bear Specialist Groups. Asia and South America are revealed as the areas most in need of urgent conservation action

Gland, Switzerland, 12 November, 2007 (IUCN) – The world’s smallest species of bear, the sun bear (Helarctos malayanus), has been classed as Vulnerable, while the giant panda (Ailuropoda melanoleuca) remains in the Endangered category on the IUCN Red List of Threatened Species.

The sun bear’s new status has been accepted for inclusion in the 2007 IUCN Red List. The sun bear lives in mainland Southeast Asia, Sumatra and Borneo and was previously listed as Data Deficient, meaning that not enough was known about the species to give it a status on the IUCN Red List.

Rob Steinmetz, co-chair of the IUCN Bear Specialist Group’s sun bear expert team, said: “Although we still have lot to learn about the biology and ecology of this species, we are quite certain that it is in trouble. We estimate that sun bears have declined by at least 30% over the past 30 years (three bear generations), and continue to decline at this rate.

“Deforestation has reduced both the area and quality of their habitat. Where habitat is now protected, commercial poaching remains a significant threat. We are working with governments, protected area managers, conservation groups and local people to prevent extinctions of the many small, isolated sun bear populations that remain in many parts of Southeast Asia.”

The only bear presently considered Endangered is the giant panda. That status remains unchanged despite enormous efforts in China directed towards its conservation, including the establishment of nearly 60 panda reserves, a ban on logging, and widespread reforestation programmes.

Dave Garshelis, co-chair of the IUCN Bear Specialist Group, said: “Quite a bit is now known about the ecology of giant pandas and substantial work and expense has been aimed at trying to estimate total numbers of these animals. However, these estimates are imprecise and prone to significant error.

“Even though some people have claimed that panda populations are on the rise, we still consider them Endangered because too much uncertainty exists to justify changing their status to Vulnerable. It would be unwise to assume that in less than 10 years under the new habitat improvement policies in China that panda populations could have dramatically increased.”

Although hunting bears is illegal throughout Southern Asia, bears suffer heavy losses from poachers, who risk the small chance of being caught against lucrative gains from selling parts. Bile from the bear’s gall bladder is used in traditional Chinese medicine and their paws are consumed as a delicacy. Additionally, bears are often killed when they prey on livestock or raid agricultural crops. Bears simply roaming near a village may be killed because they are perceived as a threat to human safety.

Dave Garshelis said: “Although we do not have any reliable population estimates for the sun bear, or any of the other Asian bears for that matter, we fear that bears in Southeast Asia are declining at a particularly rapid rate due to extensive loss of forest habitat combined with rampant poaching.”

The Bear Specialist Group concluded a meeting in Monterrey, Mexico, on November 10 and has updated the status of the seven species of terrestrial bears.

Vulnerable species include Asiatic black bears and sloth bears, both inhabitants of Asia, and Andean bears (formerly called spectacled bears) from the Andes Mountains of South America.

Sloth bears live on the Indian subcontinent, where habitat loss has been severe. They have found sanctuary mainly in reserves set up to protect tigers. The IUCN Bear Specialist Group indicated that this species might have disappeared entirely from Bangladesh during the past decade.

Brown bears, the most widespread ursid, are not listed as threatened globally because large numbers still inhabit Russia, Canada, Alaska and some parts of Europe. Nevertheless, very small, isolated, and highly vulnerable populations exist in southern Europe and central and southern Asia. Several brown bear populations are protected under national or provincial laws. Grizzly bears – brown bears living in interior North America – are considered Threatened under the U.S. Endangered Species Act outside of Alaska.

In 2006, the polar bear was listed as Vulnerable on the IUCN Red List. Technically a marine mammal, the polar bear is distinct from the other seven terrestrial bears and has a different specialist group.

Among the eight species of bears, only the American black bear is secure throughout its range, which encompasses Canada, the United States and Mexico. At 900,000 strong, there are more than twice as many American black bears than all the other species of bears combined. They are legally hunted in most parts of their range.

Bruce McLellan, co-chair of the IUCN Bear Specialist Group, said: “An enormous amount of effort and funding for conservation and management continue to be directed at bears in North America where their status is relatively favorable. It is unfortunate that so little is directed at bears in Asia and South America where the need is extreme. We are trying to change this situation but success is slow.”

Westminster's Green Plan

Heritage concern as MPs look at scheme to cut their carbon footprint

* Robert Booth
* The Guardian (c)
* Monday November 12 2007

A plan to slash the carbon footprint of the houses of parliament by almost a third using wind turbines, tidal power and underground boreholes is being considered by Palace of Westminster officials. A detailed study into the greening of the parliamentary estate, commissioned by MPs and peers shows how parliament could be partly powered by a 35m high wind turbine on the neighbouring Victoria Gardens and a field of tidal power turbines in the Thames next to the members' terraces.

New Zealand: Tongariro National Park

Vegetation reconstruction from soil phytoliths, Tongariro National Park, New Zealand

Vanessa C. Thorn


"Phytoliths are microscopic particles of opaline silica (SiO2.nH2O) formed by the accumulation and solidification of siliceous gel between and within the cells of many plants.

"Soil surface phytolith assemblages are assessed for their potential to accurately reconstruct the overlying vegetation community within the subalpine zone of Tongariro National Park, New Zealand. The results provide important new evidence that phytoliths are an under-exploited tool for reconstructing past vegetation patterns. A new technique has been developed to quantitatively compare phytolith supply with accumulation. From four study sites, plants and soil were collected for phytolith extraction, and vegetation height and canopy cover were surveyed. The results indicate that at three of the four sites, source vegetation could be satsifactorily reconstructed at a broad community level from the dispersed soil phytolith record implying similar expectations for the application of this technique to the fossil phytolith record."

New species, warm water and whales: the Antarctic's secrets revealed by melting ice

· Scientists research world sealed off for 12,000 years
· Marine life transformed by rapid climate change

(c) Alok Jha, science correspondent
Monday February 26, 2007
The Guardian (c)

"The seas around the Antarctic peninsula are among the most mysterious places on Earth - what life there is has remained largely a mystery, thanks to a thick cover of ice for the past few millennia. But the collapse of some of these ice sheets has given scientists a rare opportunity for access, and yesterday they revealed that they had found a thriving underwater world that is being transformed by climate change.

As well as new species, the Census of Marine Antarctic Life (CMAL) project found more common ones that were able to survive in the Antarctic because the temperature of the sea is rising. Minke whales were discovered in large numbers. The scientists also spotted a rare beaked whale off the coast of Elephant Island - the famous refuge of Ernest Shackleton's 21-man crew after a doomed attempt to cross Antarctica in 1916.


This pattern may not be repeated in future, however. Michael Stoddart, the leader of the CAML project, said one consequence of the rising global temperatures was a fall in plankton such as algae that grow underneath sea ice, which would have knock-on effects to animals higher up the food chain, all the way up to whales. "Algae is a source of abundant, high-quality winter food and is central to the health of the whole ecosystem," he said.


The Larsen shelf is a fringe of ice in the north-west of the Weddel Sea, extending along the east coast of the Antarctic peninsula. In 2002, scientists watched in shock as 3,250 square kilometres (1,255 sq miles) of 220-metre thick ice - the Larsen B shelf - fell into the sea. It had been stable for at least 12,000 years.

Only one type of bird more at risk

Growing genetically modified, herbicide-resistant crops has fewer negative consequences for birds than had been feared. This is one of the findings from a model developed by British researchers to assess the impact of agricultural methods on biodiversity. Simon Butler and his colleagues at the University of Reading present their model in the January issue of Science.

Risk assessment for Bt plants: two concepts

The approval of Bt plants involves complex ecological relationships. The question is: are separate tests required for each plant and the non-target organisms it may potentially affect? Or is it possible to develop suitable standard tests? The scientific community is currently discussing two different concepts.

http://www.gmo-safety.eu/en/maize/corn_borer/525.docu.html

Jörg Romeis: Ecosystems are highly complex and vary widely between regions. Nevertheless, the basic approach to the risk assessment of Bt plants is always the same. The approach has proved effective, even though it is possible that fewer species of butterfly are at risk when Bt maize is planted under Western European climate conditions than in the tropics. The procedure consists of several stages and is based on problem and risk analysis. This leads to targeted laboratory tests that are designed in such a way that they can answer a large number of the questions relating to possible risks. If the laboratory tests indicate that a particular species may be at risk, further tests are conducted in the greenhouse and, if necessary, in the field. In near-natural conditions, researchers investigate the risk in greater detail, studying for instance the probability of the particular non-target species coming into contact with the Bt protein .

http://www.gmo-safety.eu/en/maize/corn_borer/526.docu.html

Angelika Hilbeck: We can't model the diversity of ecosystems in the laboratory, but we can take individual key components of an ecosystem and examine them in the laboratory. Fundamental questions can be examined experimentally there, which is often difficult and more time-consuming and expensive to do in the field. For example, we can clarify the direct effects of the Bt protein on individual organisms. But even this is not always easy and largely depends on the chosen methodology. On the basis of findings in the laboratory or the climate chamber, we can then develop more specific questions and smarter test procedures for field studies.

Laboratory findings must ultimately be supplemented by studies in the field. It is widely known, particularly from the development of GM plants, that organisms can behave differently in the laboratory and greenhouse than they do in the wild.
