International Symposium "Marine fisheries, ecosystems and societies in West Africa: 50 years of change"Dakar, 24 - 28 June 2002Fisheries professionals and researchersfocus on the ecological and economic sustainability of fishing off West
The oceanic waters off the West coast of Africa, from Morocco down to South Africa, hold some of the world's most abundant resources of fish. Fish and other seafood are an essential part of populations' diet and of the economic and social development of these countries. Fishing fleets' catch capacities are growing, however, and the resources are... view more... (2002-07-09)
Science Prize for British-French Collaboration
Collaborative research based at NERC's Centre for Ecology and Hydrology (CEH) in Banchory, near Aberdeen, has led to a prestigious prize being awarded to a French researcher this week. Dr David Grémillet will be awarded the Prix Franco-Britannique 2003 prize of EUR5000 by the Science and Innovation Minister, Lord Sainsbury at an award... view more... (2003-09-16)
Shellfish face an uncertain future in a high CO2 world
Overfishing and disease have decimated shellfish populations in many of the world's temperate estuarine and coastal ecosystems. view more (2009-05-27)
Scientists say climate change mitigation strategies ignore carbon cycling processes of inland waters
In the paper, The Boundless Carbon Cycle, published in the September issue of Nature Geoscience, scientists from the University of Vienna, Uppsala University in Sweden, University of Antwerp, and the U.S. based Stroud™ Water Research Center argue that current international strategies to mitigate manmade carbon emissions and address climate... view more...

2-million-year-old evidence shows tool-making hominins inhabited grassland environments
In an article published in the open-access, peer-reviewed journal PLoS ONE on October 21, 2009, Dr Thomas Plummer of Queens College at the City University of New York, Dr Richard Potts of the Smithsonian Institution National Museum of Natural History and colleagues report the oldest archeological evidence of early human activities in a grassland... view more...

Big vegetarian mammals can play a critical role in maintaining healthy ecosystems, study finds
Removing large herbivorous mammals from the African savanna can cause a dramatic shift in the relative abundance of species throughout the food chain. view more (2007-01-17)
Global warming and your health
Global warming could do more to hurt your health than simply threaten summertime heat stroke, says a public health physician. view more (2006-10-24)
Gut check: Tracking the ecosystem within us
For more than 100 years, scientists have known that humans carry a rich ecosystem within their intestines. An astonishing number and variety of microbes, including as many as 400 species of bacteria, help humans digest food, mitigate disease, regulate fat storage, and even promote the formation of blood vessels. view more (2007-06-26)
Without disturbances in nature the world's forests will be impoverished
The forests of the world are not the stable and unchanging ecosystems they have been assumed to be. Without the occurrence of wide-spread disturbances in nature, such as forest fires, icing, or volcanic activity, forests will eventually be impoverished, owing to a lack of phosphorous. This is shown in a study reported in this week's issue of the... view more... (2004-06-21)
Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science. view more (2007-06-25)
Shifting baselines confound river restoration
Steep reductions in the abundance of fish, shellfish, and other aquatic fauna in recent centuries are not restricted to animals that live in the sea: historical records show that species in rivers and lakes worldwide also experienced sharp declines. view more (2009-09-01)
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)
Historical Photographs Expose Decline in Florida's Reef Fish, New Scripps Study Finds
A unique study by a scientist at Scripps Institution of Oceanography at UC San Diego has provided fresh evidence of fishing's impact on marine ecosystems. view more (2009-02-18)
ESA launches new project to protect biodiversity
The world's biodiversity is vanishing at an unprecedented rate - around 100 species every day - due to factors such as land use change and pollution. view more (2007-01-10)
California's Ancient Kelp Forest
The kelp forests off southern California are considered to be some of the most diverse and productive ecosystems on the planet, yet a new study indicates that today's kelp beds are less extensive and lush than those in the recent past. view more (2009-11-12)
Recovery from acid rain 'much slower than expected'
Acid rain was one of the world's worst pollution problems of the 1970s and 1980s, affecting large areas of upland Britain, as well as Europe and North America. view more (2007-09-28)
Scientists use lasers to measure changes to tropical forests
New technology deployed on airplanes is helping scientists quantify landscape-scale changes occurring to Big Island tropical forests from non-native plants and other environmental factors that affect carbon sequestration. view more (2009-01-26)
Exotic timber plantations found to use more than twice the water of native forests
Ecologists have discovered that timber plantations in Hawaii use more than twice the amount of water to grow as native forests use. view more (2009-09-16)
Biodiversity controls ecological 'services,' report scientists in comprehenisive analysis
Accelerating rates of species extinction pose problems for humanity, according to a comprehensive study headed by a biologist at the University of California, Santa Barbara and published in the journal Nature this week. view more (2006-10-26)
Amazon conservation policy working in Brazil, MSU-led study finds
Contrary to common belief, Brazil's policy of protecting portions of the Amazonian forest from development is capable of buffering the Amazon from climate change, according to a new study led by Michigan State University researchers. view more (2009-06-16)
