Louisiana Pine Snakes Released In Kisatchie National Forest
2012-05-08 03:30:25

On May 1, USDA Forest Service, U.S Fish and Wildlife Service, Louisiana Department of Wildlife and Fisheries, the Memphis Zoo, and other partners released seven young Louisiana pine snakes on a restored longleaf pine stand in the Kisatchie National Forest in Louisiana. The release is the fourth in 2 years, part of a plan to restore a very rare snake to its range in Louisiana. Last year the partners released 20 newly hatched snakes; this year´s snakes are 6 months old and about 3 feet...

American Forests Releases the 2012 National Register of Big Trees, which recognizes more than 760 of the country's biggest trees. Washington, D.C. (PRWEB) April 27, 2012 Today, on National Arbor Day, American Forests released the 2012 National Register of Big Trees, which shows that despite the extreme weather in the U.S. over the last year, most of the nation´s champion trees endured. The new register recognizes more than 760 of the country´s biggest trees, many of which lived...

Scientists at the University of Guelph have found a way to successfully clone American elm trees that have survived repeated epidemics of their biggest killer – Dutch elm disease. The breakthrough is the first known use of in vitro culture technology to clone buds of mature American elm trees. "This research has the potential to bring back the beloved American elm population to North America," said Prof. Praveen Saxena, a plant scientist who worked on the project with Professor...

New research reveals Artemisia tridentata seeds can form a persistent seed bank, ensuring its survival in an invasive, fire-prone system Big sagebrush (Artemisia tridentata) is a key foundational species in an ecosystem that is threatened by invasion of cheatgrass and the subsequent increase in fire frequency. Critical to the conservation, reestablishment, and restoration of the sagebrush steppe ecosystem (which comprises 63 million hectares of the Great Basin of North America) is...

Computer Model Optimizes Biofuel Operations
2012-01-18 05:00:56

Research into biofuel crops such as switchgrass and Miscanthus has focused mainly on how to grow these crops and convert them into fuels. But many steps lead from the farm to the biorefinery, and each could help or hinder the growth of this new industry. A new computer model developed at the University of Illinois can simplify this transition, researchers say. The model can run millions of simulations, optimizing operations to bring down costs, reduce greenhouse gas emissions or achieve...

Maximizing greenhouse gas savings Scientists examined current knowledge about the potential contributions of bioenergy production from switchgrass to limit greenhouse gas emissions. Their findings, published in GCB Bioenergy, conclude that the use of switchgrass bioenergy can contribute to reducing greenhouse gas emissions but encourage further research to address the significant sources of uncertainty, such as what type of land is converted to switchgrass. According to the leading...

Joint BioEnergy Institute (JBEI) Researchers Reach Milestone on the Road to Biofuels A milestone has been reached on the road to developing advanced biofuels that can replace gasoline, diesel and jet fuels with a domestically-produced clean, green, renewable alternative. Researchers with the U.S. Department of Energy (DOE)´s Joint BioEnergy Institute (JBEI) have engineered the first strains of  Escherichia coli bacteria that can digest switchgrass biomass and synthesize its...

Climate Change Could Be Fatal For Walnut Trees
2011-11-30 05:00:56

Warmer, drier summers and extreme weather events considered possible as the climate changes would be especially troublesome - possibly fatal - for walnut trees, according to research at Purdue University. Over five years, Douglass Jacobs, a professor of forestry and natural resources, and Martin-Michel Gauthier, a former doctoral student under Jacobs who is now a research scientist in the Ministry of Natural Resources in Quebec, studied the physiology of walnut trees, which are...

The best fall foliage colors can be seen by spending several days in the Blue Ridge Mountains and the Shenandoah National Park, and driving around each of those days. Choosing to stay in a cabin rental in Virginia provides a great base from which to explore. Waynesboro, VA (PRWEB) September 17, 2011 âœWhen should I come to see the peak colors?â This question causes the phones at Cabin Creekwood to ring off the hook as the days get shorter and the...
