HARRISBURG, Pa., March 13, 2014 /PRNewswire-USNewswire/ -- Governor Tom Corbett has proclaimed March 16-22 as Wildfire Prevention Week in Pennsylvania, noting drying March winds and warming temperatures quickly can combine to increase fire dangers across Pennsylvania's forests and brush lands. "Much of our state woodlands still may have snow cover but one only has to look back to last spring to see how quickly brush and forest fires can spring up when sun and wind prevail," Corbett...

HARRISBURG, Pa., March 12, 2014 /PRNewswire-USNewswire/ -- With the approach of spring and increased risk of forest and brush fires across the state, federal grants are now available to help Pennsylvania's rural communities better guard against the threat of fires in forested, undeveloped and unprotected areas. "Warming temperatures, sunny days and strong winds soon will usher in wildfire dangers that emphasize the value of having well-trained and well-equipped local firefighting...

Carbon Capture Increased From Predation On Invertebrates By Woodland Salamanders
2014-03-11 09:17:59

USDA Forest Service - Pacific Southwest Research Station Woodland salamanders perform a vital ecological service in American forests by helping to mitigate the impacts of global warming. Global warming occurs when greenhouse gases like carbon dioxide are released into the atmosphere. Woodland salamanders facilitate the capture of this carbon before it is released by feeding on invertebrates (beetles, earthworms, snails, ants, etc.) that would otherwise release carbon through...

A study of grasslands on six continents suggests a way to counteract the human-made overdose of fertilizer that threatens to permanently reduce their biodiversity: let grazing animals crop fast growing grasses. Grazers allow sunlight to reach ground level, encouraging other plants' growth, according to the study published online March 9, 2014 in Nature. College Park, MD (PRWEB) March 10, 2014 A comparative study of grasslands on six continents suggests there may be a way to counteract...

redOrbit Staff & Wire Reports - Your Universe Online By studying thousands of canopy tree species in the western Amazon, researchers from the Carnegie Institution for Science’s Department of Global Ecology have uncovered geographically nested patterns of chemical traits they say will help determine how the ecosystem will respond to changes in land use and climate. Writing in the March 3 edition of the Proceedings of the National Academy of Sciences (PNAS), the study authors set...

David Tenenbaum, University of Wisconsin-Madison MADISON, Wis. — Field ecologists go to great lengths to get data: radio collars and automatic video cameras are only two of their creative techniques for documenting the natural world. So when a group of ecologists set out to see how wind moves seeds through isolated patches of habitat carved into a longleaf pine plantation in South Carolina, they twisted colored yarn to create mock seeds that would drift with the wind much like native...

[ Watch the Video: Google Joins The Fight Against Deforestation ] redOrbit Staff & Wire Reports - Your Universe Online Google and several environmental organizations unveiled a new online forest monitoring system on Thursday that will help governments and corporations track deforestation in nearly real-time. The online forest monitoring system, dubbed Global Forest Watch, will show tree loss around the world in high resolution and with frequent updates, making it possible to...

Forest Model Predicts How Trees Compete For Canopy Space
2014-02-20 11:53:17

Brown University Out of an effort to account for what seemed in airborne images to be unusually large tree growth in a Hawaiian forest, scientists at Brown University and the Carnegie Institution for Science have developed a new mathematical model that predicts how trees compete for space in the canopy. What their model revealed for this particular forest of hardy native Metrosideros polymorpha trees on the windward slope of Manua Kea, is that an incumbent tree limb greening up a given...

Forest management is based on recommendations that are supposed to maximize economic revenues. However, in 40% of cases a better economic result would be achieved by neglecting some of the recommendations. This would also greatly benefit biodiversity. These results were obtained by a research group lead by Professor Mikko Mönkkönen at the University Jyväskylä. The group studied a production forest landscape encompassing 68 square kilometers of land and more than 30,000 forest stands in...

Rainforests
2013-04-19 19:33:20

Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...

Taiga
2013-04-19 18:21:46

Taiga, or otherwise known as boreal forest, is a biome that is characterized by coniferous forests made up mostly of spruces, larches, and pines. The taiga is the world’s largest terrestrial biome. In North America, it covers most of inland Canada and Alaska as well as portions of the extreme northern continental United States and is known as the Northwoods. It covers most of Sweden, Finland, much of Norway, lowland/coastal areas of Iceland, much of Russia, northern Kazakhstan, northern...

Environmental Science

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...
