A computer simulation tool that predicts the influence of forest clearings on soil fertility
The process of clearing consists of cutting down trees in such a way that those remaining have more resources and can grow more. The question was if too many had been cut down, with the concomitant removal of nutrients, and the manner, therefore, in which this process might affect long-term soil... view more (2004-09-08)

Soil nutrition affects carbon sequestration in forests
On December 11, USDA Forest Service (FS) scientists from the FS Southern Research Station (SRS) unit in Research Triangle Park, NC, along with colleagues from Duke University, published two papers in The Proceedings of the National Academy of Science (PNAS) that provide a more precise understanding... view more (2006-12-14)

Medieval diaries aid scientists ascertain increase in hot spots due to global warming
The study finds that the number of 'hot spots' has increased dramatically in the Northern Hemisphere in the last century compared to the past 1200 years ¬®C adding to the growing evidence of wide-scale global warming.   view more (2006-02-10)

Elvis the mystery bird has searchers scouring Arkansas habitats for signs of roosts, nests or stripped bark
Elvis. That is the nickname that Larry Mallard, refuge manager for the White River National Wildlife Refuge in southeastern Arkansas, uses for the ivory-billed woodpecker (Campephilus principalis), now being sought in Mallard's woods by Cornell Lab of Ornithology staffers and volunteers.   view more (2005-12-27)

Mode of seed dispersal greatly shapes placement of rainforest trees
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... view more (2006-11-29)

Fears raised over link between human growth hormone and CJD
Further cases of Creutzfeldt-Jakob (CJD) disease could arise as a result of human growth hormone treatment, even after low doses, suggests research in the Journal of Neurology Neurosurgery and Psychiatry.   view more (2002-05-20)

Study shows new method of growth hormone dosing improves height
A randomized UCLA study found that a new dosing paradigm can improve height outcomes in the treatment of children who have short stature due to growth hormone deficiency and idiopathic short stature.   view more (2005-06-07)

Challenges remain in reintroducing American chestnut

Predicting growth hormone treatment success
Growth hormone treatments work better on some children than on others, but judging which candidates will gain those vital inches in height is no simple task.   view more (2007-12-13)

Plants can be used to study how and why people respond differently to drugs
While prescription medications work successfully to cure an ailment in some people, in others the same dose of the same drug can cause an adverse reaction or no response at all.   view more (2007-09-27)

The science behind why leaves change colour in the Autumn
Autumn is marked out by spectacular changes in leaf colour as the greens of summer change into the yellows and reds of autumn. In parts of North American whole tourist industries are based on this change, but why do leaves turn these bright colours before falling off the trees?   view more (2004-10-04)

Ecosystem consequences of a single, genetically based plant trait
Climate is often touted as the most important regulator of decomposition and nutrient cycling processes in forest ecosystems, however, in the forthcoming issue of Ecology Letters, Schweitzer and her research team from Northern Arizona University and the University of Wisconsin, USA, demonstrate... view more (2004-02-05)

New CU-Boulder study shows diversity decreases chances of parasitic disease
A new University of Colorado at Boulder study showing that American toads who pal around with gray tree frogs reduce their chances of parasitic infections known to cause limb malformations has strong implications for the benefits of biodiversity on emerging wildlife diseases.   view more (2008-10-22)

The kapok connection -- Study explains rainforest similarities
Celebrated in Buddhist temples and cultivated for its wood and cottony fibers, the kapok tree now is upsetting an idea that biologists have clung to for decades: the notion that African and South American rainforests are similar because the continents were connected 96 million years ago.   view more (2007-06-18)

Emphasis on conifer forests places multiple species at risk
The traditional emphasis on dense, fast-growing, conifer-dominated forests in the Pacific Northwest raises questions about the health of dozens of animal species that depend on shrubs, herbs and broad-leaf trees, a new analysis by Oregon State University and the U.S. Geological Survey suggests.   view more (2007-08-24)

DO NOT HIDE FROM RAIN UNDER A FIRTREE
Russian scientists have found out that industrial contamination of atmosphere has more impact on flora and soil under the trees and the trees as such than on the space between the crowns. The study has been funded by the Russian Foundation for Basic Research and the President~s grant. We normally... view more (2000-12-15)

Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers
A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today.   view more (2007-03-29)

FSU biologist says new dinosaur is oldest cousin of Tyrannosaurus rex
Tyrannosaurus rex, meet your newest -- oldest -- cousin. Florida State University paleobiologist Gregory M. Erickson sliced up some ancient dinosaur bones uncovered in China to help an international team of scientists identify a new genus and species.    view more (2006-02-10)

Ginkgo biloba extract: More than just for memory?
Researchers at Georgetown University Medical Center say they now have a clearer picture of how an extract from the leaves of the Ginkgo biloba tree reduces the risk of aggressive cancer in animal experiments.   view more (2006-02-24)

Tropical forests leak nitrogen back into atmosphere, say scientists
In findings that could influence our understanding of climate change, a Princeton research team has learned that tropical forests return to the atmosphere up to half the nitrogen they receive each year, thanks to a particular type of bacteria that lives in those forests.   view more (2006-05-23)

UK Study Suggests Possible Link Between Colorectal Cancer And Human Growth Hormone Therapy (p 273)
Authors of an observational study in this week's issue of THE LANCET highlight a possible link between human growth hormone therapy and an increased risk of colorectal cancer. The investigators comment that further evidence is required before firm conclusions can be made, and stress that there is... view more (2002-07-24)

Pine Is Ten Times As Sensitive As Maple
Coniferous trees are widespread in Russia, especially in Siberia, where taiga extends over tens of millions of hectares. Cedars and pines grow also in the environs of cities and in city parks and suffer from human-induced changes in environment.         Of... view more (2002-05-07)
