(07/28/2008) If we could turn back the clock about 200 years, one could watch as millions of whales swam along their migration routes. Around 150 years ago, one could witness bison filling the vast America prairie or a billion passenger pigeons blotting out the sky for days. Only a few decades back and a million saiga antelope could be seen crossing the plains of Asia.
Monster manta ray species discovered
(07/25/2008) Researchers have discovered a previously unknown species of manta ray. Previously there was believed to be only a single species of ray but genetic analysis now shows there are at least two, and possibly three, species.
Facing criticism, biofuels industry forms new lobby group to influence lawmakers
(07/25/2008) Under attack by politicians, aid groups, and environmentalists for driving up food prices and fueling destruction of ecologically sensitive habitats, some of the world's largest agroindustrial firms have formed a lobby group to influence consumers and lawmakers to support continued subsidies for biofuel production, reports Reuters.

New plan would pay tropical countries for saving forests, regardless of level of threat
(07/24/2008) Deforestation and forest degradation account for around a fifth of global carbon emissions from human activities, but new policy measures are focusing reducing such emissions as a cost-effective way to fight global warming. While the concept — known as REDD for "Reducing Emissions from Deforestation and Degradation" — has found wide support from politicians, scientists, and environmentalists, there are lingering concerns over how to compensate countries that have extensive forest cover and low rates of annual forest loss, since payments are based on historical deforestation rates. A new proposal seeks to get around this issue by factoring in all the terrestrial carbon in a tropical landscape — regardless of level of threat it faces — and packaging it as a tradable commodity.
Brazil to send more police into the Amazon to fight illegal logging
(07/23/2008) Brazilian President Luiz Inacio Lula da Silva signed two decrees Tuesday to rein in illegal forest clearing in the Amazon, reports the Associated Press (AP).

Leaf-cutter ants test theories about the Amazon's biodiversity
(07/23/2008) No one knows for certain how many insect species reside in the Amazon. One oft-quoted estimate is 30 million, but the actual number could be significantly lower or higher than this. Either way, biologists have long wondered why the richness of insect diversity in the Americas' tropical forests is exponentially higher than temperate forests. Three popular hypotheses have emerged—the theory of refugia, the marine incursion hypothesis, and the riverine barrier hypothesis. To test these theories a group of scientists, headed by Dr. Scott Solomon, studied three species of leaf-cutter ant species from the Amazon.
How to replant a mangrove forest: local, low-cost initiatives prove most successful
(07/23/2008) Mangrove replanting and rehabilitation has become a widespread and important environmental initiative worldwide. Mangrove forests play key ecological roles, including sustaining fish populations and other wildlife, preventing erosion along coastlines, and acting as an overall carbon sink. Furthermore, mangroves have received attention lately for their role in providing an effective buffer against typhoons. In light of the many replanting initiatives now occurring, researchers J.H. Primavera and J.M.A. Esteban conducted a study of the overall effectiveness of different mangrove rehabilitation schemes. Their findings show that small, local, and generally cheaper initiatives have a higher success rate over large costly government and international programs.
Biofuels can reduce emissions, but not when grown in place of rainforests
(07/22/2008) Biofuels meant to help alleviate greenhouse gas emissions may be in fact contributing to climate change when grown on converted tropical forest lands, warns a comprehensive study published earlier this month in the journal Environmental Research Letters. Analyzing the carbon debt for biofuel crops grown in ecosystems around the world, Holly Gibbs and colleagues report that "while expansion of biofuels into productive tropical ecosystems will always lead to net carbon emissions for decades to centuries... [expansion] into degraded or already cultivated land will provide almost immediate carbon savings." The results suggest that under the right conditions, biofuels could be part of the effort to reduce humanity's carbon footprint.
Population of critically endangered lemurs discovered in Madagascar

Coral susceptibility to bleaching due to small differences in symbiotic relationship
(07/22/2008) Coral reefs are now considered the second most threatened group of animals in the world, with nearly one-third of corals listed as endangered (amphibians retain the dubious honor of being number one). Although corals face many threats, the greatest is bleaching caused by warming oceans due to climate change. However, some coral populations are more susceptible to bleaching than others, even including corals of the same species. New research has uncovered that the reason lies in small differences in the symbiotic relationship between corals and their symbionts, small marine animals and protozoa. Such differences, however minuscule, have a huge impact on the likelihood of a coral's ability to survive warming oceans.
Shell Oil funds "open source" geoengineering project to fight global warming

Implementing a butterfly farm: Iwokrama reserve's latest sustainable initiative
(07/20/2008) Iwokrama, which lies in the heart of Guyana's rainforest, is known worldwide for its innovative approach to preserving tropical rainforests and creating livelihoods for local communities. Their focus has been to create programs that utilize the forest sustainably, allowing for a mutual benefit between the people and the forest itself. Currently, Iwokrama has a number of initiatives under its umbrella, including eco-tourism, sustainable forestry, on-going research projects, and training programs. Amid these bustling projects, a new one has emerged: butterfly farming.

Gore launches second campaign... for Earth
(07/17/2008) In a speech Thursday, Al Gore challenged the U.S. to generate 100 percent of its electricity from zero carbon emission sources within 10 years. Speaking at Washington's Constitution Hall, Gore said America's security, environmental and economic crises are all related, and that measures to rein in greenhouse gas emissions will make the U.S. stronger, safer, and cleaner. "The survival of the United States of America as we know it is at risk," Gore said. "I don't remember a time in our country when so many things seemed to be going so wrong simultaneously."

First carbon map of America released by NASA
(07/15/2008) For the first time, one can have a whole view of America's carbon output: region by region, city by city. The Vulcan Project has undertaken a holistic inventory—including electricity, heat, transportation, and industry—of local carbon emissions across the nation to create the first carbon map of America. Texas leads the fifty states, and the county of Harris, Texas (encompassing Houston) records the nation's largest emissions by county. Although Texas is second in population after California, its massive industry puts it over the top.

Birds face higher risk of extinction than conventionally thought
(07/14/2008) Birds may face higher risk of extinction than conventionally thought, says a bird ecology and conservation expert from Stanford University. Dr. Cagan H. Sekercioglu, a senior research scientist at Stanford and head of the world's largest tropical bird radio tracking project, estimates that 15 percent of world's 10,000 bird species will go extinct or be committed to extinction by 2100 if necessary conservation measures are not taken. While birds are one of the least threatened of any major group of organisms, Sekercioglu believes that worst-case climate change, habitat loss, and other factors could conspire to double this proportion by the end of the century. As dire as this sounds, Sekercioglu says that many threatened birds are rarer than we think and nearly 80 percent of land birds predicted to go extinct from climate change are not currently considered threatened with extinction, suggesting that species loss may be far worse than previously imagined. At particular risk are marine species and specialists in mountain habitats.
Wal-Mart to ban sales of wood products from threatened rainforests

Tasmanian devil reproduction adapts to devastating, contagious cancer
(07/14/2008) Tragic circumstances have led to some astounding behvaioral changes in Tasmanian devils. A contagious form of face cancer has engulfed the population, causing the species to be listed as endangered in May. The cancer, which is characterized by large facial tumors, often leads to death by starvation. Casualty rates for infected areas are nearly 90 percent. However, a new study shows that the Tasmanian devils are not taking the disease lying down. The devils, which usually wait until two years for sexual maturity, have begun to breed within their first year of life.

1/3 of corals face extinction
(07/10/2008) Nearly one-third of reef-building corals are vulnerable to extinction, according to an assessment of 845 species of coral. Rising temperatures, increased incidence of disease, and human disturbance are driving the trend.
Pine beetles attack Canada, boosting GHG emissions
(07/10/2008) The mountain pine beetle, a small tree-devouring insect, has deforested an area of British Columbia the size of Louisiana — over 130,000 square kilometers. The 5 millimeter insect is a perfect tree-destroying machine. The beetles bore through the tree's bark to reach the phloem of the tree, which contains the tree's organic nutrients. The beetles then feed on these nutrients and lay their eggs. The trees defend themselves by secreting extra resin, but the beetles are often able to combat this by releasing a blue fungi. In about two weeks time, the tree turns a tell-tale red and essentially starves to death. The mountain pine beetles move on.
The global rich are eating the poor's fish: new report shows tropical fish catch gravely under-estimated
(07/10/2008) After a week of bad news regarding marine life — it was reported that half of U.S. coral reefs are in fair to poor condition and one-third of all coral species are threatened globally — there is still more: a study of twenty tropical islands showed that recreational and subsistence fishing has gone almost completely unreported from 1950 to 2004. In fifteen of twenty cases the fish take was at least doubled when local fish catches were added, and in the most extreme case, American Samoa, the amount of fish collected was 17 times what was previously recorded.
Palm oil industry moves into the Amazon rainforest
(07/09/2008) Malaysia's Land Development Authority FELDA has announced plans to immediately establish 100,000 hectares (250,000) of oil palm plantations in the Brazilian Amazon. The agency will partner with Braspalma, a local company, to form Felda Global Ventures Brazil Sdn Bhd. FELDA will have a 70 percent stake in the venture. The announcement had been expected. Last month Najib said Malaysia would seek to expand its booming palm oil industry overseas. The country is facing land constraints at home.
