(AP) -- Four years after being placed on the Endangered Species List, the dwindling sea otters of southwest Alaska on Wednesday were given an important recovery tool. http://www.physorg.com/news174198176.html Biology Thu, 08 Oct 2009 06:30:01 EST news174198176 Many of Washington State's sea otters are exposed to the same pathogens responsible for causing disease in marine mammal populations in other parts of the country, according to a study published by researchers from NOAA's Olympic Coast National Marine Sanctuary, the U.S. Fish and Wildlife Service and their partners. http://www.physorg.com/news160833458.html Biology Wed, 06 May 2009 13:04:06 EST news160833458 (PhysOrg.com) -- UC Davis researchers trying to understand the sea otter's slow recovery in California have found an important clue: Some sea otters feed almost exclusively on animals that raise their risk of being infected with potentially deadly parasites. http://www.physorg.com/news153685029.html Biology Thu, 12 Feb 2009 18:17:59 EST news153685029 Sea otters living along the central California coast risk higher exposure to disease-causing parasites as a consequence of the food they eat and where they feed. http://www.physorg.com/news151607815.html Biology Mon, 19 Jan 2009 17:17:34 EST news151607815 Sea otters are known as a keystone species, filling such an important niche in ocean communities that without them, entire ecosystems can collapse. Scientists are finding, however, that sea otters can have even farther-reaching effects that extend to terrestrial communities and alter the behavior of another top predator: the bald eagle. http://www.physorg.com/news142227666.html Biology Fri, 03 Oct 2008 04:41:06 EST news142227666
