New NOAA report offers in-depth look at Northwestern Hawaiian islands marine life, ecosystems
A new NOAA report on the Northwestern Hawaiian Islands (NWHI), protected by the Papahānaumokuākea Marine National Monument, provides the sharpest picture yet of the region's marine life and ecosystems. view more (2009-05-22)
New study shows extent of harmful human influences on global ecosystems
More than 40 percent of the world's oceans are heavily impacted by human activities, including overfishing and pollution, according to a new study that will appear in tomorrow's peer-reviewed journal Science. view more (2008-02-15)
Nature can help reduce greenhouse gas, but only to a point
Plants apparently do much less than previously thought to counteract global warming, according to a paper to be published in next week's online edition of Proceedings of the National Academy of Sciences. view more (2006-04-11)
NOAA report states half of US coral reefs in 'poor' or 'fair' condition
Nearly half of U.S. coral reef ecosystems are considered to be in "poor" or "fair" condition according to a new NOAA analysis of the health of coral reefs under U.S. jurisdiction. view more (2008-07-08)
New Window Opens on the Secret Life of Microbes: Scientists Develop First Microbial Profiles of Ecosystems
Nowhere is the principle of "strength in numbers" more apparent than in the collective power of microbes: despite their simplicity, these one-cell organisms--which number about 5 million trillion trillion strong (no, that is not a typo) on Earth--affect virtually every ecological process, from the decay of organic material to the... view more...

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)
Plan to conserve forests may be detrimental to other ecosystems
Conserving biodiversity must be considered when developing plans to reduce greenhouse gas emissions from deforestation, researchers warn in today's edition of Science. view more (2008-06-13)
Scientists aim to bring indigenous people into climate change monitoring and policy
Scientists at the Missouri Botanical Garden are calling for the inclusion of indigenous peoples around the world in helping monitor the effects of global climate change and develop policy. view more (2009-05-13)
How fish species suffer as a result of warmer waters
Ongoing global climate change causes changes in the species composition of marine ecosystems, especially in shallow coastal oceans. view more (2007-01-05)
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... view more... (2003-07-02)
Spreading antibiotics in the soil affects microbial ecosystems
Antibiotics used extensively in intensive livestock production may be having an adverse effect on agricultural soil ecosystems. view more (2009-03-30)
Thawing permafrost increases greenhouse gas emission from subarctic mires
The permafrost in the mires of subarctic Sweden is undergoing dramatic changes. The part of the soils that thaws in the summer, the so-called active layer, has become deeper since 1970 and the permafrost has disappeared altogether in some locations. This has lead to significant changes in the vegetation composition and subsequent increase in... view more... (2004-02-24)
Marine researchers explore sediment highways
A European team of researchers has demonstrated that sediment is transported to the deep sea via canyons in the seabed. The sediment accumulates in the head of the submarine canyons. At the end of the canyons, mud avalanches disperse into the deep sea. Scientists from the Netherlands Institute for Sea Research (NIOZ) presented their findings at an... view more... (2002-04-18)
Industrial contaminants spread by seabirds in High Arctic, new Canadian study shows
Seabirds are the surprising culprits in delivering pollutants - through their guano - to seemingly pristine northern ecosystems, a new Canadian study shows. view more (2005-07-15)
Modest fisheries reduction could protect vast coastal ecosystems: UBC research
A reduction of as little as five per cent in fisheries catch could result in as much as 30 per cent of the British Columbia coastal ecosystems being protected from overfishing, according to a new study from the UBC Fisheries Centre. view more (2009-07-22)
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)
Overfishing puts Southern California kelp forest ecosystems at risk, report scientists
Kelp forest ecosystems that span the West Coast -- from Alaska to Mexico's Baja Peninsula -- are at greater risk from overfishing than from the effects of run-off from fertilizers or sewage on the shore. view more (2006-05-26)
"Acid rain" and forest mass: another perspective
A few years ago the study of the effects of atmospheric deposition on forest ecosystems reached beyond the scientific sphere and the term "acid rain" was coined. view more (2005-10-14)
Dramatic shift from simple to complex marine ecosystems occurred 250M years ago at mass extinction
The earth experienced its biggest mass extinction about 250 million years ago, an event that wiped out an estimated 95% of marine species and 70% of land species. New research shows that this mass extinction did more than eliminate species: it fundamentally changed the basic ecology of the world's oceans. view more (2006-11-27)
Beaver dams create healthy downstream ecosystems
Beavers, long known for their beneficial effects on the environment near their dams, are also critical to maintaining healthy ecosystems downstream. view more (2006-06-06)
