Wenchuan earthquake mudslides emit greenhouse gas
Mudslides that followed the 12 May 2008 Wenchuan, China earthquake, ranked by the US Geological Survey as the 11th deadliest earthquake ever recorded, may cause a carbon-dioxide release in upcoming decades equivalent to two percent of current annual global carbon emissions from fossil fuel combustion, a new study shows. view more (2009-03-03)

Greenhouse ocean may downsize fish
By 2100, warmer oceans with more carbon dioxide may no longer sustain 1 of the world's most productive fisheries, says USC marine ecologist. view more (2008-01-14)
New Approach Needed if Fish Stocks are to Survive
A new approach to fisheries management, taking into account the full range of human impacts on the ecosystem, is needed if fish stocks are to survive, according to Professor Chris Frid of the University of Newcastle upon Tyne, speaking at the EurOCEAN European Conference on Marine Science and Ocean Technology in Galway today. "Fishing is... view more... (2004-05-11)
University of Toronto study shows climate change will lead to less ultraviolet radiation over northern high latitudes
Physicists at the University of Toronto have discovered that changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet (UV) radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada. view more (2009-09-16)
Global changes alter plant growth schedule
Any gardener knows that different plant species mature at different times. Scientists studying natural plant communities know this phenomenon allows species to co-exist by reducing overlap so there is less competition for limited resources. view more (2006-09-05)

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)
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)

Researchers offer new theory for dogfish and skate population outburst on George's Bank
New research by scientists at the University of Maryland Center for Environmental Science Chesapeake Biological Laboratory questions the long-held belief that a lack of predators and competitors was the primary cause for the increase of skates and dogfish observed in Southern New England's George's Bank following overfishing of commercially... view more...

Decades of accumulated change court ecosystem catastrophe
Subjected to decades of gradual change by humans, many of the world’s natural ecosystems – from coral reefs and tropical forests to northern lakes and forests – appear susceptible to sudden catastrophic ecological change, an international consortium of scientists reports Thursday October 11 in the journal Nature. “Models... view more...
