Hot volcanic eruptions could lead to a cooler Earth
Volcanic eruptions may be an agent of rapid and long-term climate change, according to new research by British scientists. view more (2005-06-13)
MIT's ocean model precisely mimics microbes' life cycles
Scientists at MIT have created an ocean model so realistic that the virtual forests of diverse microscopic plants they "sowed" have grown in population patterns that precisely mimic their real-world counterparts. view more (2007-03-30)
Nitrogen - the silent species eliminator
Nitrogen pollution from agriculture and fossil fuels is known to be seriously damaging grasslands in the UK. A new European study is starting to show that the effect is Europe-wide, confirming that current policies to protect ecosystems may need a re-think. view more (2007-10-15)
Human impacts on coral reefs of Northwestern Hawaiian islands revealed
Results of a new study shed light on how threats to the world's endangered coral reef ecosystems can be more effectively managed. view more (2009-04-08)
Potentially harmful chemicals found in forest fire smoke
Researchers have detected common plant toxins that affect human health and ecosystems in smoke from forest fires. The results from the new study also suggest that smoldering fires may produce more toxins than wildfires - a reason to keep human exposures to a minimum during controlled burns. view more (2009-04-30)
Japanese beetle may help fight hemlock-killing insect
The eastern hemlock, a tall, long-lived coniferous tree that shelters river and streamside ecosystems throughout the eastern United States and Canada, is in serious danger of extinction because a tiny, non-native insect is literally sucking the life out of it. view more (2007-09-11)
Scientist Names Top Five Invasive Plants Threatening Southern Forests in 2009
U.S. Forest Service Southern Research Station (SRS) Ecologist Jim Miller, Ph.D., one of the foremost authorities on nonnative plants in the South, today identified the invasive plant species he believes pose the biggest threats to southern forest ecosystems in 2009. view more (2009-01-13)
Rising acidity levels could trigger shellfish revenue declines, job losses
Changes in ocean chemistry - a consequence of increased carbon dioxide (CO2) emissions from human industrial activity - could cause U.S. shellfish revenues to drop significantly in the next 50 years, according to a new study by researchers at the Woods Hole Oceanographic Institution (WHOI). view more (2009-06-18)
Global sunscreen won't save corals
Emergency plans to counteract global warming by artificially shading the Earth from incoming sunlight might lower the planet's temperature a few degrees, but such "geoengineering" solutions would do little to stop the acidification of the world oceans that threatens coral reefs and other marine life. view more (2009-06-17)
BYU study: How an Antarctic worm makes antifreeze and what that has to do with climate change
Two BYU researchers who just returned from Antarctica are reporting a hardy worm that withstands its cold climate by cranking out antifreeze. And when its notoriously dry home runs out of water, it just dries itself out and goes into suspended animation until liquid water brings it back to life. view more (2009-02-10)
Loss of top predators causing surge in smaller predators, ecosystem collapse
The catastrophic decline around the world of "apex" predators such as wolves, cougars, lions or sharks has led to a huge increase in smaller "mesopredators" that are causing major economic and ecological disruptions, a new study concludes. view more (2009-10-02)
Researchers discover forests of endangered tropical kelp
A research team led by San Jose State University and the University of California, Santa Barbara has discovered forests of a species of kelp previously thought endangered or extinct in deep waters near the Galapagos Islands. view more (2007-09-27)
Radar tracking reveals that butterflies follow decisive flight paths
The charming meanderings of butterflies are not as random as they appear, according to new research. Scientists at Rothamsted Research, a research institute sponsored by the Biotechnology and Biological Sciences Research Council (BBSRC) in Hertfordshire, have found that their seemingly irresolute flutterings are in fact decisive flight paths. The... view more... (2005-04-05)
Ocean acidification threatens cold-water coral ecosystems
Corals don't only occur in warm, sun-drenched, tropical seas; some species are found at depths of three miles or more in cold, dark waters throughout the world's oceans. view more (2006-04-03)
High human impact ocean areas along US West Coast revealed
Climate change, fishing and commercial shipping top the list of threats to the ocean off the West Coast of the United States. view more (2009-05-11)
Database shows effects of acid rain on microorganisms in Adirondack Lakes
Prior to the federal Clean Air Act, unhindered industrial emissions were released into the air throughout the Midwestern and Eastern United States for decades. Many of those harmful chemicals came right back down to earth in the form of acid rain, a chemical concoction that includes nitric and sulfuric acid. view more (2008-06-24)
New protocol tracks how land use influences the way streams work
Virginia Tech biology researchers have applied tools from geology, geography, and hydrologic modeling to determine the effect of different land uses on stream quality across 10 watersheds of the French Broad River in the North Carolina mountains. view more (2005-10-13)
Scientists map West coast areas most affected by humans
Climate change, fishing, and commercial shipping top the list of threats to the ocean off the West Coast of the United States. view more (2009-05-12)
Hold your breath; Plants may absorb less carbon dioxide than we thought
The world's land plants will probably not be able to absorb as great a share of the rising atmospheric carbon dioxide as some models have predicted. view more (2006-04-13)
New study shows fish respond quickly to changes in mercury deposition
Reducing atmospheric mercury emissions should quickly reduce mercury levels in lake fish, according to a three-year study published this week in the Proceedings of the National Academy of Science. view more (2007-09-20)
