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.... view more (2004-05-04)

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... 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... view more (2003-07-02)

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... view more (2003-10-08)

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)

Scientific design of GM farm-scale evaluations made public
The 40th anniversary issue of the British Ecology Society's Journal of Applied Ecology this month leads with two major papers describing the background, methodology and experimental design of the farm-scale evaluations of genetically modified herbicide-tolerant crops. In laying out the statistical... view more (2003-02-07)

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)

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)

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)

Ecosystem consequences of a single, genetically based plant trait
Climate is often touted as the most important regulator of decomposition and nutrient cycling processes in forest ecosystems, however, in the forthcoming issue of Ecology Letters, Schweitzer and her research team from Northern Arizona University and the University of Wisconsin, USA, demonstrate... view more (2004-02-05)

At the root of nutrient limitation, ecosystems are not as different as they seem
Anyone who has thrown a backyard barbecue knows that hot dogs are inexplicably packaged in different numbers than buns - eight hot dogs per pack versus 10 hot dog buns. Put in ecological terms, this means that weenie roasts are "hot-dog limited" - the extra buns are worthless without hot... view more (2007-11-09)

Biodiversity promotes evolutionary change
Evolutionary biologists at the University of East Anglia have discovered a new link between biodiversity and the evolution of new species.   view more (2005-04-18)

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)

From parasitism to mutualism: Partner control in asymmetric interactions
What prevents an exploitative individual from taking advantage of a cooperative partner? Most attempts to answer this question focus on reciprocity - exploitation may not pay, if it triggers retaliation. But in many encounters, only one individual can exploit the other. For example, when coral... view more (2002-09-09)

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)

Resilience concepts poised to aid management of coastal marine ecosystems
The January 2008 issue of BioScience includes a special section entitled "Managing for Resilience in Coastal Marine Ecosystems." The four articles in the section highlight different aspects of attempts to incorporate modern concepts from mathematical ecology into ecosystem-based... view more (2008-01-02)

UGA study reveals ecosystem-level consequences of frog extinctions
Streams that once sang with the croaks, chirps and ribbits of dozens of frog species have gone silent. They're victims of a fungus that's decimating amphibian populations worldwide.   view more (2008-10-17)

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... view more (2004-05-11)

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... view more (2008-05-19)

University of Kent course run in partnership with modern wonder of the world
The news that Kew Gardens is to join the likes of the Taj Mahal and the Great Wall of China as a modern wonder of the world has been welcomed by teachers on the University of Kent's MSc Programme in Ethnobotany. Together with the Durrell Institute of Conservation and Ecology (DICE), the Department... view more (2003-07-11)

Evaluating ecosystem services
Environmental conservation efforts have traditionally focused on protecting individual species or natural resources. Scientists are discovering, however, that preserving the benefits that whole ecosystems provide to people is more economically and environmentally valuable. At the Annual Meeting of... view more (2008-08-05)

Discovering an ecosystem beneath a collapsed Antarctic ice shelf
The chance discovery of a vast ecosystem beneath the collapsed Larsen Ice Shelf will allow scientists to explore the uncharted life below Antarctica's floating ice shelves and further probe the origins of life in extreme environments.   view more (2005-07-19)

Antarctic icebergs: unlikely oases for ocean life
Icebergs have long gripped the popular imagination, whether as relatively run-of-the-mill floating hazards that cause "unsinkable' ships to founder or, more recently, as enormous breakaway pieces of ice the size of states or small countries.   view more (2007-06-25)

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... view more (2006-03-30)
