- Climate changes brews trouble for marine life in European Seas, Marine Board-ESF report says
03-02-2007 · EurekAlert!
There is no denying that climate changes have profound impacts on the world and especially on the marine environment. Recent research has shown that the Northern Hemisphere has been warmer since 1980 than at any other time during the last two millenniums. As a result the increase in temperature under climate change was generally higher in northern than in southern European seas.

- Smithsonian study concludes Caribbean extinctions occurred 2M years after apparent cause
03-12-2007 · EurekAlert!
Smithsonian scientists and colleagues report a new study that may shake up the way paleontologists think about how environmental change shapes life on Earth. The researchers summarized the environmental, ecological and evolutionary consequences for Caribbean shallow-water marine communities when the Isthmus of Panama was formed. They concluded that extinctions resulting when one ocean became two were delayed by 2 million years.

- Condition of bluefin tuna in gulf of maine is declining
08-23-2007 · EurekAlert!
The quality of giant bluefin tuna caught in the Gulf of Maine has declined significantly since the early 1990s, researchers at the University of New Hampshire have found by analyzing detailed logbooks from a commercial tuna grader at the Yankee Fisherman's Co-op. The findings, published this week in Fishery Bulletin, indicate potential changes in food sources, shifts in reproductive or migratory patterns, or the impact of fishing may be the cause of this decline.

- Connection between virus and Colony Collapse Disorder in bees
09-06-2007 · EurekAlert!
A team led by scientists from the Columbia University Mailman School of Public Health, Pennsylvania State University, the USDA Agricultural Research Service, University of Arizona, and 454 Life Sciences has found a significant connection between the Israeli Acute Paralysis Virus (IAPV) and Colony Collapse Disorder (CCD) in honey bees. The findings, an important step in addressing the disorder that is decimating bee colonies across the country, are published in the journal Science this week.
