When fish become extinct, the cycling of critical nutrients in ecosystems changes, Cornell study finds
Ecosystems are such intricate webs of connections that few studies have been able to explore exactly what happens when a species dies out. view more (2007-03-05)
Seeing the forest and the trees
With human emissions of carbon dioxide on the rise, there is growing interest in maintaining the Earth's natural mechanisms that absorb and store carbon. view more (2005-10-24)
Time to tap climate-change-combating potential of the world's ecosystems
Investing in restoration and maintenance of the Earth's multi-trillion dollar ecosystems - from forests and mangroves to wetlands and river basins - can have a key role in countering climate change and climate-proofing vulnerable economies. view more (2009-09-02)
Manipulating biotope space can enhance beneficial biodiversity effects
Using diverse plant mixtures instead of monocultures can increase yield and other ecosystem goods and services on which humans depend. Recent studies showed that such beneficial effects of biodiversity depend on complementarity between species in resource use, as is the case if species root in different soil depths. This knowledge led to the... view more... (2004-06-10)
Darwin and the world's first ecological experiment
Scientists examining the work that influenced Charles Darwin have rediscovered the details of what may be the world's first ecological experiment. Darwin, in his Origin of Species of 1859, referred to an experiment investigating the biology of grassland plants that showed how a greater diversity of grasses planted in experimental plots was... view more...

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)
Heavy metals in the Peak District -- evidence from bugs in blanket bogs
Bacteria that consume heavy metals have been found in some of the most contaminated parts of the Peak District in the Southern Pennines and may be changing the pollutants into more toxic forms that could leak out into reservoirs. view more (2008-04-02)
Actions of individuals key to saving biodiversity-and ourselves, Stanford biologists say
Even if you don't like the outdoors, you're probably pretty fond of air, clean water and food. That makes you a fan of biodiversity, because those essentials for life-human and otherwise-are maintained as a direct result of the Earth's biodiversity, the abundance and variety of species and populations on the planet. Preserving a substantial amount... view more... (2008-08-12)
A Closer Look at the Hudson Canyon Shows Why the Canyon is Critical for Fish
A series of newly discovered pits in the bottom of the Hudson Canyon, 100 miles southeast of New York Harbor, may be a key ingredient for the abundant and diverse marine ecosystem in and around the canyon. view more (2009-12-02)
Alpine rivers hold important clues for preserving biodiversity and coping with climate change
Marginal plants, particularly trees, play a crucial role in sustaining the biodiversity of Europe's big river systems, according to a recently held workshop organised by the European Science Foundation (ESF). view more (2008-11-18)
For carnivorous plants, slow but steady wins the race
Like the man-eating plant in Little Shop of Horrors, carnivorous plants rely on animal prey for sustenance. Fortunately for humans, carnivorous plants found in nature are not dependent on a diet of human blood but rather are satisfied with the occasional fly or other insect. view more (2009-09-15)
Early hominid first walked on two legs in the woods
Among the many surprises associated with the discovery of the oldest known, nearly complete skeleton of a hominid is the finding that this species took its first steps toward bipedalism not on the open, grassy savanna, as generations of scientists - going back to Charles Darwin - hypothesized, but in a wooded landscape. view more (2009-10-09)
Microbe understudies await their turn in the limelight
On the marine microbial stage, there appears to be a vast, varied group of understudies only too ready to step in when "star" microbes falter. view more (2010-01-12)
Elevated Carbon Dioxide Changes Soil Microbe Mix Below Plants
A detailed analysis of soil samples taken from a forest ecosystem with artificially elevated levels of atmospheric carbon dioxide (CO2) reveals distinct changes in the mix of microorganisms living in the soil below trembling aspen. view more (2007-12-20)
New study provides insight on energy development and sage-grouse habitat in the intermountain West
A study released October 14th in the current issue of the peer-reviewed journal PLoS ONE will shed new light on oil and gas development potential in the Intermountain West. view more (2009-10-16)
New Caledonia Lagoon: Sediment Transport Tracking And Prediction
Researchers have for several years now been using numerical modelling in the southwestern lagoon of New Caledonia to work out marine current circulation patterns and obtain detailed knowledge of its hydrodynamics. The lagoon has been subject to substantial sediment inputs generated by erosion and human activity. An IRD team has developed a... view more... (2003-09-24)
Your own private global warming
A group of researchers from the British Antarctic Survey have collected individuals from a wide range of species commonly found in Antarctic waters and subjected them to increasing levels of water temperature to learn how each species is prepared to cope with the conditions that they are likely to experience in the future. view more (2009-06-30)
Arctic Sediments Show That 20th Century Warming Is Unlike Natural Variation
The possibility that climate change might simply be a natural variation like others that have occurred throughout geologic time is dimming, according to evidence in a Proceedings of the National Academy of Sciences paper published today. view more (2009-10-26)
Damage to threatened Gulf of California habitats can be reversed
Once described by Jacques Cousteau as the "world's aquarium," the marine ecosystems of the Gulf of California are under threat. Destructive new fishing methods are depleting the sea's habitats, creating areas that are ghosts of their former existences (see Scripps explorations story "Threatened Gulf". view more (2010-02-22)
Ecological Changes in the North Sea as a Consequence of Biological Globalisation and Climate Change
Long-term monitoring studies at the 'Biologische Anstalt Helgoland' (BAH), part of the Alfred Wegener Institute for Polar and Marine Research, document rapid ecological changes in the North Sea. Scientists explain these changes primarily with the introduction of non-native species and global climate change. Investigations that have been carried... view more... (2005-01-31)
