Study shows that parasites form the thread of food webs
Scientists have discovered that parasites are suprisingly important in food webs and their findings appear in a report published this week in the Early Edition of the on-line version of the Proceedings of the National Academy of Sciences. view more (2006-07-13)
Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams. view more (2006-12-12)
Tiny Marine Organisms Reflect Ocean Warming
Sediment cores collected from the seafloor off Southern California reveal that plankton populations in the Northeastern Pacific changed significantly in response to a general warming trend that started in the early 1900s. view more (2006-01-06)
The Arctic and Global Warming
A warmer Arctic Ocean may mean less food for the birds, fish, and baleen whales and be a significant detriment to that fragile and interconnected polar ecosystem, and that doesn't bode well for other ocean ecosystems in the future. view more (2006-02-21)
Limpets reveal possible fate of cold-blooded Antarctic animals
A limpet no bigger than a coin could reveal the possible fate of cold-blooded Antarctic marine animals according to new research published this week in The Journal of Experimental Biology. view more (2007-07-24)
Two new lakes found beneath Antarctic ice sheet
The Earth Institute at Columbia University-Lying beneath more than two miles of Antarctic ice, Lake Vostok may be the best-known and largest subglacial lake in the world, but it is not alone down there. view more (2006-01-26)
Colombian Frog Believed Extinct Found Alive
Researchers exploring a Colombian mountain range found surviving members of a species of Harlequin frog believed extinct due to a killer fungus wiping out amphibian populations in Central and South America. view more (2006-05-19)
Global warming may have damaged coral reefs forever
Global warming has had a more devastating effect on some of the world's finest coral reefs than previously assumed, suggests the first report to show the long-term impact of sea temperature rise on reef coral and fish communities. view more (2006-05-16)
No safe ground for life to stand on during world's largest mass extinction
The world's largest mass extinction was probably caused by poisonous volcanic gas, according to research published today. view more (2005-12-02)
Grasslands won't help buffer climate change as carbon dioxide levels rise
Because grasslands and forests operate in complex feedback loops with both the atmosphere and soil, understanding how ecosystems respond to global changes in climate and element cycling is critical to predicting the range of global environmental changes-and attendant ecosystem responses-likely to occur. view more (2005-08-09)
Marine conservation organizations team up to conduct Indonesia coral reefs assessment
Three leading marine conservation organizations will complete an extensive survey next week along the west coast of Aceh Province, Indonesia, to determine the impact of last year's devastating earthquake and tsunami on the region's coral reefs. view more (2005-10-13)
Study casts doubt on 'Snowball Earth' theory
"Snowball Earth" proponents, who say that Earth's oceans were covered by thick ice, explain the survival of life by hypothesizing the existence of small warm spots, or refugia. view more (2005-09-30)
All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon species. In the June issue of Ecology Letters, Smith... view more... (2003-05-22)
Smithsonian scientists report new carbon dioxide study
Researchers at the Smithsonian Environmental Research Center report the results of a six-year experiment in which doubling the atmospheric greenhouse gas carbon dioxide (CO2) in a scrub oak ecosystem caused a reduction in carbon storage in the soil. view more (2007-03-13)
Overfishing puts Southern California kelp forest ecosystems at risk, report scientists
Kelp forest ecosystems that span the West Coast -- from Alaska to Mexico's Baja Peninsula -- are at greater risk from overfishing than from the effects of run-off from fertilizers or sewage on the shore. view more (2006-05-26)
New 150 Million-Year-Old Crab Species Discovered
Researchers from Kent State University and the University of Bucharest, Romania, have discovered a new primitive crab species Cycloprosopon dobrogea in eastern Romania. Previously unexamined, these ancient crabs from the Prosopidae family existed more than 150 million years ago during the Jurassic period. view more (2007-10-18)
Biodiversity conservation may help reduce the impacts of natural disasters - UNU
As ministers meet at the Eighth Meeting of the Conference of the Parties to the Convention on Biological Diversity (CBD COP-8), the United Nations University (UNU) urges governments to incorporate the Millennium Ecosystem Assessment (MA) findings in national planning processes and poverty reduction strategies to promote ecosystem services that may... view more...

Deep-sea species' loss could lead to oceans' collapse, study suggests
The loss of deep-sea species poses a severe threat to the future of the oceans, suggests a new report publishing early online on December 27th and in the January 8th issue of Current Biology, a publication of Cell Press. view more (2007-12-28)
Accelerating loss of ocean species threatens human well-being
An international group of ecologists and economists has shown that the loss of biodiversity is profoundly reducing the ocean's ability to produce seafood, resist diseases, filter pollutants and rebound from stresses such as overfishing and climate change. view more (2006-11-07)
Yellowstone ecosystem may lose key migrant
A mammal that embarks on the longest remaining overland migration in the continental United States could vanish from the ecosystem that includes Yellowstone and Grand Teton National Parks, according to a study by the Wildlife Conservation Society (WCS) and National Park Service. view more (2006-07-11)
