Arctic Marine Mammals Act as Ecosystem Sentinels Amid Changing Climate
2014-02-14 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Polar bears, walruses, seals and other Arctic marine mammals act as ecosystem sentinels, according to a new study, which suggests that the behaviors of the animals can be used to provide clues about how the ecosystem is responding to a changing climate. The news was presented this week at the 2014 meeting of the American Association for the Advancement of Science in Chicago. NOAA oceanographer Sue Moore presented the findings, highlighting how various Arctic marine mammals are responding to...

Arctic Biome Under Extreme Threat From A Changing Climate
2014-02-14 19:17:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: The Arctic as we know it may not exist as climate change is threatening the polar biomes unique biodiversity and landscape, according to a new report from a large international team of scientists. Conducted by the Conservation of Arctic Flora and Fauna (CAFF) under the Arctic Council, an international forum of Arctic nations, the new study found that climate change could shrink Arctic ecosystems, as advancing changes move north and butt up against the perimeter of the Arctic Ocean, a phenomenon...

Loss of Arctic Sea Ice Eliminates Major Barrier for Parasites in Marine Mammals
2014-02-14 18:12:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: The great Arctic thaw--up to 50 percent of sea ice by area and 75 percent by volume in the summer season--could be offering new opportunities for one of the planets most successful parasites. Toxoplasma gondii, an infection spread by almost all cat species, has been identified for the first time in the western Arctic Beluga whale. Toxoplasma is found almost everywhere that cats settle: domestic pets, ocelots, cougar, wild cats all carry and spread oocysts of the parasite (structures it uses to...
Cat parasite found in Arctic Beluga
2014-02-14 18:03:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: The cat parasite Toxoplasma gondii, which can cause blindness in people, has been identified in Beluga in the western Arctic. The discovery by University of British Columbia scientists has prompted a health advisory to Inuit people in the region who eat the whale's meat. Researchers say it is an example of how the warming of the Arctic is allowing the freer movement of pathogens. Icier conditions in the past acted as an obstruction to infectious agents. "Ice is a significant ecological...
