How forest management and deforestation are impacting climate

Coniferous (dark green) and broadleaved (light green) trees in summer in Alsace (France) exhibit differences in surface properties. This material relates to a paper that appeared in the Feb. 5, 2016, issue of <i>Science</i>, published by AAAS. The paper, by K. Naudts at Institut Pierre Simon Laplace in Gif-sur-Yvette, France, and colleagues was titled, "Europe's forest management did not mitigate climate warming."Two new studies reveal how altering the composition of trees in forests is influencing not only the carbon cycle, but air surface temperatures to a significant degree as well. The...

Discovery: Many white-tailed deer have malaria

In the lab of University of Vermont biologist and malaria expert Joseph Schall (back), Ellen Martinsen, a researcher at the Smithsonian and adjunct at UVM, helped confirm a discovery she and colleagues made: a malaria parasite that infects white-tailed deer. It's the first-ever malaria parasite known to live in a deer species and the only native malaria parasite found in any mammal in North or South America. Their results were published in the journal <i>Science Advances</i>.Two years ago, Ellen Martinsen, was collecting mosquitoes at the Smithsonian's National Zoo, looking for malaria that might infect birds--when she discovered something strange: a DNA profile, from parasites in...

Central Appalachia flatter due to mountaintop mining

Years of blowing away mountain ridges in search of coal and depositing the excess rock in nearby valleys have dramatically flattened the landscape in parts of Central Appalachia. This animation shows an elevation map of West Virginia's Mud River watershed before and after mountaintop mining became widespread. To see the impact on other West Virginia watersheds, visit <a target="_blank"href="http://www.minedwatersheds.com/">http://www.minedwatersheds.com/</a>.Forty years of mountaintop coal mining have made parts of Central Appalachia 60 percent flatter than they were before excavation, says new research by Duke University.
