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)
Grazer diversity counteracts plant diversity effects on ecosystem functioning in seagrass beds
Several influential experiments have shown that high plant diversity enhances ecosystem productivity, animal diversity, and invasion resistance. Yet theory predicts that plant and herbivore diversity, which often co vary in nature, should have countervailing effects on ecosystem properties. In the July issue of Ecology Letters, Duffy, Canuel, and... view more... (2003-07-02)
EPA teams with National Geographic Society and World Resources Institute to map ecosystem services
The U.S. Environmental Protection Agency (EPA) is collaborating with the National Geographic Society and the World Resources Institute to develop tools that will help to fully account for the value of ecosystem services. view more (2008-10-30)
Catastrophic shift in species diversity and productivity of an ecosystem
Ecology and environmental management is largely predicated on the view that ecosystems respond to environmental changes in a smooth and straightforward way. However, in Ecology Letters, May, Schmitz reports on a long-term field experiment that may prompt a hard, critical look at this reigning view. In the experimental system, top predators... view more... (2004-05-04)
Gray wolves feed the masses while hunters feed the few
Gray wolves (Canis lupus) and human hunters both provide resource subsidies to scavengers in Yellowstone National Park, USA, by provisioning them with the remains of their kills. Carrion from wolf versus hunter kills is much more dispersed in both time and space. In the November issue of Ecology Letters, scientists from Berkeley and Yellowstone... view more... (2003-10-08)
Media invitation: How many species in Noah's Arc?
Scientists gather in Mallorca (Spain) to assess the role of biodiversity in ecosystem function. The remarkable increase, towards the end of 20th Century in the rate of species extinctions and the loss of biological diversities in the planet's ecosystems have generated considerable concern on the consequences that, beyond the severe damage of the... view more...

Integrating restoration and conservation within the ecosystem approach
The Society for Ecological Restoration International (SER) released its May 2008 Briefing Note on the "Opportunities for Integrating Ecological Restoration & Biological Conservation within the Ecosystem Approach" at the Convention on Biological Diversity's Ninth Conference of the Parties held in Bonn, Germany, May 19-30, 2008. view more (2008-05-19)
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...

Scientists to hand "crisis-hit" European fisheries a lifeline
Scientists from the University of Newcastle upon Tyne are leading an international programme aimed at handing European fisheries a lifeline. The University has just signed a Euro 1.5m. contract with the European Union for the development of a fisheries management framework that includes consideration of the wider ecosystem. It will also involve... view more... (2001-11-26)
Ecological restoration as a tool for reversing ecosystem fragmentation
Ecosystem fragmentation, along with many other global trends, is causing the natural world to undergo profound changes at all spatial scales from the micro-habitat to the continental. view more (2008-10-09)
Theory of oscillations may explain biological mysteries
New mathematical studies of the interactions between oscillating biological populations may shed light on some of the toughest questions in ecology, including the number and types of species in an ecosystem, according to an article in the December 2006 issue of BioScience. view more (2006-12-04)
Yale study offers new paradigm on ecosystem ecology
Predators have considerably more influence than plants over how an ecosystem functions, according to a Yale study published today in Science. view more (2008-02-15)
New study finds biodiversity conservation secures ecosystem services for people
Healthy ecosystems that provide people with essential natural goods and services often overlap with regions rich in biological diversity, underscoring that conserving one also protects the other, according to a new study. view more (2007-12-06)
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)
Human impacts and environmental factors are changing the northwest Atlantic ecosystem
Fish in U.S. waters from Cape Hatteras to the Canadian border have moved away from their traditional, long-time habitats over the past four decades because of fundamental changes in the regional ecosystem. view more (2009-09-01)
Frozen hair holds secrets of Yellowstone grizzlies
Locks of hair from more than 400 grizzly bears are stored at Montana State University, waiting to tell the tale of genetic diversity in the Yellowstone Ecosystem. view more (2007-12-19)
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)
Hareless: Yellowstone's rabbits have vanished, study says
A new study by the Bronx Zoo-based Wildlife Conservation Society found that jack rabbits living in the Greater Yellowstone Ecosystem have apparently hopped into oblivion. view more (2008-02-15)
Atlantic snails are increasing dramatically in size, Queen's researcher discovers
A Queen's University biologist has discovered that the shell lengths of northwest Atlantic Ocean snails - an important member of the Atlantic food chain - have increased by 22.6 per cent over the past century. Until now, this significant change in the marine ecosystem has gone unnoticed. view more (2009-03-25)
Oil palm research in context: Identifying the need for biodiversity assessment
Oil palm (Elaeis guineensis) cultivation has expanded dramatically in recent decades and is frequently cited as a major threat to tropical biodiversity. view more (2008-02-13)
