2014-04-21 11:45:00

USDA Forest Service In the most densely forested and most densely populated quadrant of the United States, forests reflect two centuries of human needs, values and practices. Disturbances associated with those needs, such as logging and clearing forests for agriculture and development, have set the stage for management issues of considerable concern today, a U.S. Forest Service study reports. The report – Five anthropogenic factors that will radically alter forest conditions and...

Autumn Ending Later And Spring Starting Earlier In The Northern Hemisphere
2014-03-31 11:19:49

University of Southampton A study by the University of Southampton suggests that on average the end of Autumn is taking place later in the year and Spring is starting slightly earlier. A team of researchers examined satellite imagery covering the northern hemisphere over a 25 year period (1982 - 2006), and looked for any seasonal changes in vegetation by making a measure of its ‘greenness’. They examined in detail, at daily intervals, the growth cycle of the vegetation –...

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...

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...
