Conserving biodiversity could benefit the world's poor
Land areas that are a priority for wildlife conservation provide relatively high levels of ecosystem services such as pollination, water purification, food production, and climate regulation, so safeguarding them is expected to benefit people. View News Article (2012-01-12)


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 and Knapp show that with a more realistic... View News Article (2003-05-22)


Researchers analyze 'the environmentalist's paradox'
Global degradation of ecosystems is widely believed to threaten human welfare, yet accepted measures of well-being show that it is on average improving globally, both in poor countries and rich ones. View News Article (2010-09-01)


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 Richardson provide experimental support for this... View News Article (2003-07-02)


NOAA report reviews ecosystem management in national marine sanctuaries
A new NOAA report assesses the role National Marine Sanctuaries play in helping implement ecosystem-based management practices in U.S. waters. View News Article (2010-08-03)


The grass is always greener
As biodiversity declines worldwide, there is concern that this will lead to declines in the services that ecosystems provide for people, such as food production, carbon storage, and water purification. View News Article (2011-08-22)


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 News Article (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 instrumentally control species diversity and productivity... View News Article (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 estimated the total amount of carrion consumed over... View News Article (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 losses themselves, these losses may have on the...
