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...

Google's New Mapping Tool Fights Deforestation
2014-02-21 06:36:11

[ 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...

Naturally regrowing woodlands in the subtropics can help to reduce declines in Australia’s reptiles, scientists have proposed. Research at the National Environmental Research Program’s (NERP) Environmental Decisions Hub has found that woodlands in the Australian subtropics can be restored as a haven for native reptiles if cleared areas are left to regrow. In turn, reptiles such as skinks, dragons, and geckos help restore the woodland ecosystems by providing links in the food chain....

Researchers Reveal Nine Steps To Save Waterways
2014-01-31 13:55:37

The University of British Columbia The key to clean water and sustainable fisheries is to follow nine guiding principles of water management, says a team of Canadian biologists. Fish habitats need ecosystems that are rich in food with places to hide from predators and lay eggs, according to the framework published today in the journal Environmental Reviews. Humans have put key freshwater ecosystems at risk because of land development and the loss of the vegetation along rivers and...

Predictions For Climate Change Effects On Savanna Vegetation Best Done By Continent
2014-01-31 08:05:48

North Carolina State University A "one-size-fits-all" model to predict the effects of climate change on savanna vegetation isn't as effective as examining individual savannas by continent, according to research published in Science this week. Savannas – grasslands dotted with trees – cover about 20 percent of the earth's land and play a critical role in storing atmospheric carbon, says Dr. William Hoffmann, associate professor of plant and microbial biology at North Carolina State...

Population Size Of Salamanders Helps Predict Forest Ecosystems Health, Inform Forest Management Decisions
2014-01-23 08:09:00

Jeff Sossamon - University of Missouri Researchers suggest a balance between timber harvest and conservation biology Woodland salamanders are small, lungless amphibians that live in moist, forest habitats throughout the US and the world. Salamanders often serve as vital links in forest food chains; their population size and recovery from major disturbances can help predict the health of forest ecosystems. Now, researchers at the University of Missouri have determined that...

Prices for forestry lands in Uruguay have more than doubled since 2006 BOSTON, Jan. 16, 2014 /PRNewswire/ -- In 2013, more than three quarters of all Latin American plantation forests owned by overseas financial investors, were in just two countries, Brazil and Uruguay. As prices for agricultural land soar in those countries, timberland investors are exploring other Latin American countries to invest in. The future investment prospects for Latin American Plantation Forests are the subject of...

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...
