Chicago Canal Poisoned to Keep Invasive Carp Out of Great Lakes

Thu, 03 Dec 2009 09:43:00 EST

State and Federal agencies have begun poisoning a nearly 6-mile stretch of the Chicago Sanitary Ship Canal to kill off invasive Asian carp while maintenance is performed on an electrical barrier intended to keep the fish out of Lake Michigan. The Lake’s ecosystem is already irreparably damaged by invasive species making the introduction of these new invasive fish a dire threat to the entire Great Lakes system. The fish can grow to 100 pounds in size and out-compete native species in an ecosystem.

Not Just the Polar Bear: Ten American Species Feeling the Heat from Climate Change

A new report, America’s Hottest Species, highlights a variety of American wildlife that is currently threatened by climate change from a small bird to a coral reef to the world’s largest marine turtle.

Mars Meteorite Reexamined for Signs of Life Using New Analysis

Mon, 30 Nov 2009 10:07:00 EST

A controversial Mars meteorite is once again in the spotlight as scientists use a new kind of analysis on the rock. The study is reminiscent of initial research, published in 1996, suggesting that tiny iron sulfide and iron oxide grains in the meteorite had biological origins, and that tiny, worm-shaped objects in the rock could be the fossilized remains of Martian microbes.

Global Salmon Study Shows 'Sustainable' Food May Not Be So Sustainable

Popular thinking about how to improve food systems for the better often misses the point, according to the results of a three-year global study of salmon production systems. Rather than pushing for organic or land-based production, or worrying about simple metrics such as "food miles," the study finds that the world can achieve greater environmental benefits by focusing on improvements to key aspects of production and distribution.

East Antarctic ice began to melt faster in 2006

East Antarctica's ice started to melt faster from 2006, which could cause sea levels to rise sooner than anticipated, according to a study by scientists at the University of Texas. In the study published in Nature's Geoscience journal, scientists estimated that East Antarctica has been losing ice mass at an average rate of 5 to 109 gigatonnes per year from April 2002 to January 2009, but the rate speeded up from 2006.

Asian carp may be near U.S. Great Lakes

There are signs Asian carp may have breached barriers designed to keep the prolific fish out of the Great Lakes, which could spell ecological disaster for the vital source of fresh water, authorities said on Friday. Concentrations of DNA discovered by Notre Dame University researchers may indicate the presence of bighead and silver carp upstream from two electrical barriers designed to bottle up the invasive fish.
