Biologists determined that short-term, seasonal exposure to pesticides in rivers and basins may limit the growth and size of wild salmon populations. In addition to the widespread deterioration of salmon habitats, these findings suggest that exposure to commonly used pesticides may further inhibit the recovery of threatened or endangered populations. http://www.physorg.com/news180182664.html Biology Wed, 16 Dec 2009 10:45:54 EST news180182664 (PhysOrg.com) -- For thousands of years, humans have bred pigs for desirable traits, such as more muscle and less fat in the meat. Domestication makes animals ideal models for studying how genes control physical traits because when humans selectively breed animals for the best physical features, they are also selecting for the genes controlling those traits. http://www.physorg.com/news180087491.html Biology Tue, 15 Dec 2009 08:40:02 EST news180087491 Sweden will this winter allow its first wolf hunt in 45 years following a decision by the Scandinavian country's parliament to limit their number, authorities said on Wednesday. http://www.physorg.com/news179003923.html Biology Wed, 02 Dec 2009 19:19:01 EST news179003923 (PhysOrg.com) -- Cotton growers will be better able to keep an eye out for two common pests because of a comprehensive survey by Agricultural Research Service (ARS) scientists at College Station, Texas. http://www.physorg.com/news178912351.html Biology Tue, 01 Dec 2009 18:10:04 EST news178912351 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. http://www.physorg.com/news178297283.html Space & Earth Tue, 24 Nov 2009 15:16:35 EST news178297283 (PhysOrg.com) -- Over 45 million turkeys are eaten by Americans each Thanksgiving, according to the U.S. Department of Agriculture. Hunters provide some -- last autumn, about 24,000 wild turkeys were harvested in Pennsylvania. Vegetarians might serve up a soybean-based alternative, like Tofurky. However, most holiday tables feature a Broad-Breasted White, the breed that makes up over 99 percent of grocery-store turkeys. But with the trend in locally raised food, the "heritage turkey" is experiencing a surge in popularity. http://www.physorg.com/news177860968.html Biology Thu, 19 Nov 2009 14:00:03 EST news177860968 (PhysOrg.com) -- Many of us will sit down with our families to a wonderful turkey dinner this Thanksgiving.

However, ever since the worldwide surge in genetically modified corn, critical consumers' appetites have abated somewhat. After all, it was not clear precisely how wild animals digest transgenic corn and whether or not residues actually accumulate in meat, for example. Molecular biologists from the Technische Universitaet Muenchen (TUM) have shown that there is no need for concern - also with regard to the inadvertent dispersal of genetically modified corn via wild animal feces. http://www.physorg.com/news175792791.html Biology Mon, 26 Oct 2009 17:10:01 EST news175792791 Botanists at Britain's Kew Gardens have collected seeds from 10 percent of the world's wild plants, their first goal in a long-term project to protect all endangered species, they said Thursday. http://www.physorg.com/news174815972.html Biology Thu, 15 Oct 2009 09:00:56 EST news174815972 (AP) -- ViaSat Inc. is acquiring WildBlue Communications Inc., a provider of high-speed Internet access via satellite, for $568 million in cash and stock, the companies said Thursday. http://www.physorg.com/news173591516.html Technology Thu, 01 Oct 2009 05:15:27 EST news173591516 Wild salmon and farmed salmon can now be distinguished from each other by a technique that examines the chemistry of their scales. http://www.physorg.com/news173532203.html Chemistry Wed, 30 Sep 2009 12:50:02 EST news173532203 A new study into the social networks of Tasmanian devils may help prevent the further spread of an extinction-threatening disease.

The reason is related to dogs` 10,000-year history of hanging around human food refuse dumps, she suggests. http://www.physorg.com/news166808234.html Biology Tue, 14 Jul 2009 16:50:05 EST news166808234 Wild birds of several species are dying in large numbers from a paralytic disease with hitherto unknown cause in the Baltic Sea area.
