African elephants get 9-year reprieve
(06/14/2007) African countries have agreed to extend a ban on ivory exports for another nine years. In a deal reached Wednesday at the meeting of the UN Convention on International Trade in Endangered Species (CITES) in The Hague, four African countries will be allowed to sell their ivory stockpiles to raise funds for conservation and community development efforts. The ivory had been intercepted from black market transactions and the sale by Botswana, Namibia, South Africa and Zimbabwe had been previously approved. The four countries say their elephant populations are increasing thanks to conservation and law enforcement efforts.
U.S. bird populations plummet

10-20% of birds extinct by 2100 due to global warming, deforestation
(06/04/2007) Ten to twenty percent of the world's terrestrial bird species could be threatened with extinction by 2100 due to climate change and habitat destruction reports a study published in the June 5 issue of the journal PLoS Biology. The numbers are in line with estimates published last year in The Proceedings of the National Academy of Sciences. Combining future projections on global warming, agricultural expansion and human population growth from the global Millennium Ecosystem Assessment with current geographic ranges of the world's 8,750 species of terrestrial birds, researchers Walter Jetz, David Wilcove, and Andrew Dobson estimate that 950 to 1800 species may be condemned to extinction by 2100.
Colorful marine creatures discovered off Panama
(05/31/2007) Researchers have discovered five new species of sea slug off the coast of Central America. Surveys have found that the region, known as the Tropical Eastern Pacific, is characterized by large numbers of endemic and previously unknown species. The Smithsonian Tropical Research Institute (STRI) reports that recent expeditions have turned up 5 new species of nudibranchs--a group of mollusks lacking outer shells. The discoveries are important because nudibranchs have developed "sophisticated chemical defense mechanisms" which can help with the development of novel medicinal products.

Neon green gecko key to preventing Mauritian plant extinction
(04/17/2007) A vibrantly colored gecko plays a key role in a highly threatened ecological community in Mauritius reports new research published in American Naturalist. Studying plant-animal interactions in Mauritius, an Indian Ocean island famous for its extinct dodo bird, researchers found that a rare plant, Trochetia blackburniana, benefits from its proximity to Pandanus plants because they house high densities of geckos responsible for pollination. The findings, which unusually identify a lizard as a key pollinator, are significant because they provide "valuable management insights for ongoing conservation efforts to save the highly endangered flora of Mauritius.
Bad news for frogs; amphibian decline worse than feared
(04/16/2007) Chilling new evidence suggests amphibians may be in worse shape than previously thought due to climate change. Further, the findings indicate that the 70 percent decline in amphibians over the past 35 years may have been exceeded by a sharp fall in reptile populations, even in otherwise pristine Costa Rican habitats. Ominously, the new research warns that protected areas strategies for biodiversity conservation will not be enough to stave off extinction. Frogs and their relatives are in big trouble.

The news of extinction: western media's response to the demise of the Baiji
(04/01/2007) The news came and went with an alacrity that I found alarming, almost jolting. I waited for weeks, faithfully; I could not believe that the initial announcement would be followed by nothing but silence on the issue, no rationalizations, no opinions, no discussions, no outpourings of grief. Just silence.
Overfishing of sharks causing shellfish decline
(03/29/2007) Overfishing of large sharks is reducing the abundance of shellfish reports a study published in the March 30 issue of the journal Science. A team of Canadian and American biologists has found that population declines in large predatory shark species -- including bull, great white, dusky, and hammerhead sharks -- due to overfishing has led to a boom in their ray, skate, and small shark prey species along the Atlantic Coast of the United States. Now these smaller species are depleting commercially important shellfish.
Some corals may survive acidification caused by rising CO2 levels
(03/29/2007) Several studies have shown that increased atmospheric carbon dioxide levels are acidifying the world's oceans. This is significant for coral reefs because acidification strips carbonate ions from seawater, making it more difficult for corals to build the calcium carbonate skeletons that serve as their structural basis. Research has shown that many species of coral, as well as other marine microorganisms, fare quite poorly under the increasingly acidic conditions forecast by some models. However, the news may not be bad for all types of corals. A study published in the March 30 issue of the journal Science, suggests that some corals may weather acidification better than others.
Dinosaur extinction didn't produce current mammal evolution
(03/28/2007) A new Nature study argues that the demise of dinosaurs did not fuel the rise of mammals. Devising a new tree of life for 4,500 species of mammals using molecular evolutionary trees, an international team of researchers challenges the prevailing hypothesis that a mass extinction of dinosaurs 65 million years ago played a major role in the diversification of mammals.
Logging reduces abundance of rare mammals in Borneo
(03/27/2007) Selective logging profoundly reduces the abundance of rare forest species according to surveys of logged and unlogged rainforests on the island of Borneo, one of the most biodiverse parts of southeast Asia. The results, published in a trio of papers, have implications for biodiversity and forest conservation efforts in one of the world's most threatened ecosystems.
Climate change will cause biomes to shift and disappear
(03/26/2007) Many of the world's local climates could be radically changed if global warming trends continue, reports a new study published in the early online edition of the journal Proceedings of the National Academy of Sciences. The authors warn that current climates may shift and disappear, increasing the risk of biodiversity extinction and other ecological changes.
Sachs says biodiversity extinction crisis avoidable
(03/26/2007) In a Guardian editorial published Wednesday, Jeffrey Sachs called for action to stem mounting losses of global biodiversity. Sachs, director of the Earth Institute at Columbia University and Special Advisor to United Nations Secretary-General Ban Ki-Moon, says humans are the primary cause for depletion of the world's biological richness.
Extinction, like climate change, is complicated
(03/26/2007) Extinction is a hotly debated, but poorly understood topic in science. The same goes for climate change. When scientists try to forecast the impact of global change on future biodiversity levels, the results are contentious, to say the least. While some argue that species have managed to survive worse climate change in the past and that current threats to biodiversity are overstated, many biologists say the impacts of climate change and resulting shifts in rainfall, temperature, sea levels, ecosystem composition, and food availability will have significant effects on global species richness.
