Snowy owl -- a marine species?
Wildlife satellite studies could lead to a radical re-thinking about how the snowy owl fits into the Northern ecosystem. view more (2008-12-11)
Brown Scientists Say Biodiversity Is Crucial to Ecosystem Productivity
In the first experiment involving a natural environment, scientists at Brown University have shown that richer plant diversity significantly enhances an ecosystem's productivity. view more (2008-04-25)
Scientists find grass yield, carbon storage not affected by creepy-crawlies in the soil
New results from experiments at a unique ecology facility show that plant communities are dramatically altered by changes to the type of animal species living among their roots, but that key ecosystem measurements such as overall agricultural yield or the amount of soil carbon stored are unaffected. According to the results of a three year study... view more... (2002-10-18)
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 dogs to fill them. view more (2007-11-09)
Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams. view more (2006-12-12)
Global curbs on overfishing are beginning to work
Australian Beth Fulton, a fishery ecosystem scientist from the CSIRO Wealth from Oceans Flagship, was among an international team of 19 co-authors of a report on a two-year study, led by US scientists Dr Boris Worm of Dalhousie University and Dr Ray Hilborn of the University of Washington. view more (2009-07-31)
MODELKEY - The key to clean surface waters
Analysing and evaluating chemical pollution - that is the goal of the new European large-scale project MODELKEY, starting in February. Under the management of the Centre for Environmental Research Leipzig-Halle, Germany (UFZ) researchers in 13 countries will be developing methods to identify so-called key chemicals and their effect on the water... view more...

International team shows mercury concentrations in fish respond quickly to increased deposition
A joint Canadian-American research team have, for the first time, demonstrated that mercury concentrations in fish respond directly to changes in atmospheric deposition of the chemical. view more (2007-09-18)
Wildlife variety is the spice of life, say scientists
Strictly embargoed for release 19:00 BST / 14:00 EST Wednesday 4 July 2001 Biodiversity is more than just a pretty face - it has an important role in the workings of the living world say results published in Nature today by scientists in the UK and France. They find that the specialisation of different plant species to different roles... view more... (2001-07-02)
NOAA bans commercial harvesting of krill
The National Oceanic and Atmospheric Administration (NOAA) today published a final rule in the Federal Register prohibiting the harvesting of krill in the Exclusive Economic Zone (EEZ) off the coasts of California, Oregon, and Washington. view more (2009-07-14)
Perennial vegetation, an indicator of desertification in Spain
A team of scientists has analyzed 29 esparto fields from Guadalajara to Murcia and has concluded that perennial vegetation cover is an efficient early warning system against desertification in these ecosystems. The study has been published in the Ecology magazine. view more (2009-09-04)
Loss of just one species makes big difference in freshwater ecosystem, study finds
Researchers at Dartmouth, Cornell University, and the University of Wyoming have learned that the removal of just one important species in a freshwater ecosystem can seriously disrupt how that environment functions. This finding contradicts earlier notions that other species can jump in and compensate for the loss. view more (2006-08-21)
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)
XIVth International Colloquium on Soil Zoology and Ecology
Soils provide humans with a whole range of irreplaceable ecosystem services the production and maintenance of which are largely dependent on the actions of the animal communities which inhabit them. Apart from the substantial agricultural production made necessary by humanity's demand for food, soils filter and store water, holding back erosion... view more... (2004-08-30)
Wolf reintroduction proposed in Scottish Highland test case
Researchers are proposing in a new report that a major experiment be conducted to reintroduce wolves to a test site in the Scottish Highlands, to help control the populations and behavior of red deer that in the past 250 years have changed the whole nature of large ecosystems. view more (2009-07-21)
Grasslands won't help buffer climate change as carbon dioxide levels rise
Because grasslands and forests operate in complex feedback loops with both the atmosphere and soil, understanding how ecosystems respond to global changes in climate and element cycling is critical to predicting the range of global environmental changes-and attendant ecosystem responses-likely to occur. view more (2005-08-09)
Novel living system recreates predator-prey interaction
The hunter-versus-hunted phenomenon exemplified by a pack of lionesses chasing down a lonely gazelle has been recreated in a Petri dish with lowly bacteria. view more (2008-04-14)
Experts Warn Ecosystem Changes Will Continue to Worsen, Putting Global Development Goals At Risk
A landmark study released today reveals that approximately 60 percent of the ecosystem services that support life on Earth - such as fresh water, capture fisheries, air and water regulation, and the regulation of regional climate, natural hazards and pests - are being degraded or used unsustainably. Scientists warn that the harmful consequences of... view more... (2005-03-30)
Asphalt flows from deep-sea volcanoes
New kind of volcano discovered in the Gulf of Mexico Underwater volcanoes that spew asphalt instead of lava: they were discovered in the Gulf of Mexico during an expedition of the research vessel SONNE, led by Prof. Gerhard Bohrmann of the DFG Research Center Ocean Margins. On these volcanoes the multinational team of scientists encountered a... view more... (2004-05-17)
New Study To Investigate Demise Of Coral Reef Ecosystems
Scientists are embarking on a project which will explore how global warming is devastating one of the world's most diverse ecosystems. One sixth of the world's coral reefs died due to bleaching in 1998, and the situation is getting worse. Bleaching occurs when tropical seas heat up above there normal maximums, killing the corals. These events... view more... (2004-07-30)
