[Sawf News - Lifestyles] Return of predatory crabs poise threat to Antarctic sea life: "Nowhere else than in these ecosystems do giant sea spiders and marine pillbugs share the ocean bottom with fish that have antifreeze proteins in their blood," says Rich Aronson, professor of biological sciences at Florida Institute of Technology in Melbourne, Fla. "The shell-cracking crabs, fish, sharks and rays that dominate bottom communities in temperate and tropical zones have been shut out of Antarctica for millions of years because it is simply too cold for them."

[PARTHA DAS SHARMA's Weblog on "Keeping World Environment Safer and Greener"] Ozone layer - Effective checking of its thinning would reduce ...: - Human activity is by far the most prevalent and destructive source of ozone depletion, while threatening volcanic eruptions are less common.  Human activity, such as the release of various compounds containing chlorine or bromine, accounts for approximately 75 to 85 percent of ozone damage.  Perhaps the most evident and destructive molecule of this description is chloroflourocarbon (CFC).  CFCs were first used to clean electronic circuit boards, and as time progressed, were used in aerosols and coolants, such as refrigerators and air conditioners.  When CFCs from these products are released into the atmosphere, the destruction begins.  As CFCs are emitted, the molecules float toward the ozone rich stratosphere.  Then, when UV radiation contacts the CFC molecule, this causes one chlorine atom to liberate.  This free chlorine then reacts with an ozone (O3) molecule to form chlorine monoxide (ClO) and a single oxygen molecule (O2).  This reaction can be illustrated by the following chemical equation:  Cl + O3 –> O2 + ClO.  Then, a single oxygen atom reacts with a chlorine monoxide molecule, causing the formation of an oxygen molecule (O2) and a single chlorine atom (O + ClO –>

[Outdoor and Andinia News] Food Choices and Location Influence California Sea Otter Exposure ...: "Recovery of the sea otter in California has been especially sluggish at the center portion of its range, where sea otter densities are highest and where most of the reproduction occurs," said Tim Tinker, a U.S. Geological Survey (USGS) sea otter expert at Santa Cruz, Calif., and co-lead of a new study led by the University of California-Davis and USGS. "Where food resources are limited, individual sea otters tend to become diet specialists, and the specific skills used to secure food are passed on from mother to pup."
