Invasive grass may impede forest regeneration
04-09-2007 · EurekAlert!The non-native invasive grass Microstegium vimineum may hinder the regeneration of woody species in southern forests. Chris and Sonja Oswalt (Forest Service Southern Research Station) and Wayne Clatterbuck (University of Tennessee) set up experiments on a mixed-hardwood forest in southwest Tennessee to study the growth of the invasive grass under different levels of forest disturbance. Study results were published online in the journal Forest Ecology and Management on March 27, 2007.

- Slow but sure -- Burned forest lands regenerate naturally
04-04-2007 · EurekAlert!
A new study of forest lands that burned in the 1990s in northern California and southwestern Oregon has concluded there is a "fair to excellent" chance that an adequate level of conifers will regenerate naturally, in sites that had no manual planting or other forest management. Whether lands should be planted and weed competition controlled is more a question of short-term timber production, tree species control and forest management goals than the regeneration of the forest, the study indicated.

- Predicting the perfect predator
02-13-2008 · EurekAlert!
Garlic mustard has become an invasive species in temperate forests across the United States, choking out native plants on forest floors and threatening ecosystem diversity. University of Illinois ecologist Adam Davis has created a computer model that in combination with quarantined research tests he believes will be able to predict the perfect predator -- a pest that can be introduced into a forested area that will help reduce the garlic mustard population.

- Rove beetles act as warning signs for clear-cutting consequences
06-12-2007 · EurekAlert!
New research from the University of Alberta and the Canadian Forest Service has revealed the humble rove beetle may actually have a lot to tell us about the effects of harvesting on forests species. Rove beetles can be used as indicators of clear-cut harvesting and regeneration practices and can be used as an example as to how species react to harvesting. It has been found that after an area of forest was harvested, the many forest species, including rove beetles, decreased dramatically.

- Mellow in Europe, crazy in America
02-26-2007 · EurekAlert!
Reed canarygrass stays put in Europe where it's native, but is aggressively expanding into wetlands across North America. Using this grass as a model, University of Vermont researchers have revealed a new way that some plants become invasive: Multiple introductions of the same species from numerous regions lead to new strains which grow more aggressively than the original plants. With climate change, this kind of invader may become increasingly successful.

- Refugia of the Brazilian Atlantic rainforest could be the basis for its regeneration
09-05-2007 · EurekAlert!
Changes that have occurred in Brasil tropical rainforest for more than 100 000 years were studied by a team of IRD researchers. They combined data from botany, palynology and genetics. Results indicated that this tropical. Such a finding should be useful for identification of such blocks of original forest, refugia that could be the basis for the forest's conservation in the face of climate change.

- Study shows radiofrequency ablation highly effective in treating kidney tumors
08-01-2007 · EurekAlert!
Radiofrequency ablation, a relatively new, minimally invasive treatment, was 100 percent successful in eradicating small malignant kidney tumors in a study of more than 100 patients, report researchers from Wake Forest University Baptist Medical Center. Of 95 tumors that were smaller than 3.7 cm, all were completely eradicated by a single treatment, along with 14 of the larger tumors. Total success rate for all tumors was 93 percent.

- Rising Temperatures Will Lead To Loss Of Trout Habitat In Southern Appalachians
10-05-2006 · ScienceDaily
USDA Forest Service research projects that between 53 and 97 percent of natural trout populations in the southern Appalachians could disappear due to the warmer temperatures predicted under two different global climate circulation models. In an article published Oct. 2 in the online version of the Transactions of the American Fisheries Society, Patricia Flebbe, research biologist at the FS Southern Research Station unit in Blacksburg, Va., maps out trout habitat in a future, warmer climate.

- Mode of seed dispersal greatly shapes placement of rainforest trees
11-28-2006 · EurekAlert!
The apple might not fall far from the tree, but new research shows that how it falls might be what is most important in determining tree distribution across a forest. This study of the seed dispersal methods of rainforest trees demonstrates that these methods play a primary role in the organization of plant species in tropical forests.
