Concerns Over Tree Pests And Diseases On The rise
2013-11-15 12:57:15

University of Southampton New research has found that the number of pests and disease outbreaks in trees and forests across the world has been increasing. The review "The consequences of Tree Pests and Diseases for Ecosystem Services" by scientists from the universities of Southampton, Cambridge, Oxford and St Andrews is published today (15 November) in the journal Science. The research shows that the experience of widespread death of trees, similar to that seen from Dutch elm...

Google Aids Researchers In Mapping Global Forest Gain And Loss
2013-11-15 11:45:08

Ranjini Raghunath for redOrbit.com – Your Universe Online A team of researchers from the University of Maryland, Google and the US government has put together the first comprehensive, high-resolution map of changes in global forest cover over the last 12 years. The study, published online on November 14, in the journal Science, shows that the world lost nearly 900,000 square miles of forest cover and gained less than half that number between 2000 and 2012. The map was developed...

WASHINGTON, Nov. 14, 2013 /PRNewswire-USNewswire/ -- The ravages of deforestation, wildfires, windstorms, and insects on global forests during this century are revealed in unprecedented detail in a new study based on data from the NASA-U.S. Geological Survey Landsat 7 satellite. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The maps resulting from the study are the first to document forest loss and gain using a consistent method around the globe, at high resolution....

How Plants In Arid Lands Gain Nutrients To Survive
2013-11-06 11:48:07

Marine Biological Laboratory The vast sagebrush landscapes of the western United States are one of the largest ecosystems in North America.  Long, cold winters and hot, dry summers characterize these cold desert ecosystems and create bone-dry soils during seasonal droughts. New research published this week from MBL (Marine Biological Laboratory) senior scientist Zoe Cardon, John Stark (Utah State University), and their two former students, sheds light on how desert plants gain nutrients...

EILEEN FISHER, Quiksilver, prAna, Patagonia, and lululemon athletica join forces with Canopy to stop the world's endangered forests from being logged for clothing NEW YORK, VANCOUVER and LOS ANGELES, Oct. 31, 2013 /PRNewswire/ - An exciting and innovative development in global forest conservation and fashion sustainability is being unveiled today in North America's style capital. Visionary fashion industry leader EILEEN FISHER and award winning environmental organization Canopy...

Pragmatic Approach To Saving What Can Be Saved
2013-10-17 10:45:55

Technische Universität Darmstadt How can biodiversity be preserved in a world in which traditional ecosystems are increasingly being displaced by “man-made nature”? Biologists at the TU Darmstadt and ETH Zurich have developed a new concept for conservation measures that incorporates current landscapes formerly considered ecologically “of little value”. Numerous experiences from islands have shown that this concept has a positive effect on biodiversity. Now the authors are...

Using Animal Behavior Data To Better Inform Mathematical Models Of Animal Movements
2013-10-16 15:31:44

Max-Planck-Gesellschaft Many animals are adapting to human encroachment of their natural habitats. Carnivores in particular require territories of sufficient size and so are often forced to move between numerous small habitat patches. To date, scientists often use mathematical models to predict these important routes, but fishers fitted with GPS sensors are now showing that their calculations may be missing the mark if they ignore animal behavior. Corridors are spaces that receive too...

Climate Change Produces Complicated Consequences For North America's Forests
2013-10-15 11:35:58

Dartmouth College Dartmouth-led study is the most comprehensive review of warming's impacts on forest pests, diseases Climate change affects forests across North America – in some cases permitting insect outbreaks, plant diseases, wildfires and other problems -- but Dartmouth researchers say warmer temperatures are also making many forests grow faster and some less susceptible to pests, which could boost forest health and acreage, timber harvests, carbon storage, water recycling and...

Temperature Increase Puts Terrestrial Ecosystems At Risk Of Major Shifts
2013-10-08 11:39:45

European Geosciences Union Over 80% of the world's ice-free land is at risk of profound ecosystem transformation by 2100, a new study reveals. "Essentially, we would be leaving the world as we know it," says Sebastian Ostberg of the Potsdam Institute for Climate Impact Research, Germany. Ostberg and collaborators studied the critical impacts of climate change on landscapes and have now published their results in Earth System Dynamics, an open access journal of the European Geosciences...

Trees Might Store More Carbon Than Thought
2013-10-03 07:03:41

DOE/Pacific Northwest National Laboratory Examining a long-lived forest, researchers have found that Black Spruce trees, which dominate the northern forests of North America, succumb about five years after being weakened by environmental stresses. Without rejuvenating fire, the dead trees aren't being replaced by new ones. The result will help researchers better understand how climate change affects the health of forests, and how forests affect the severity of climate change. The study...

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
2014-01-12 00:00:00

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...
