Ecosystem Chemistry Better Predicted By Plant Species
2013-04-09 09:49:55

Carnegie Institution Carnegie scientists have found that the plant species making up an ecosystem are better predictors of ecosystem chemistry than environmental conditions such as terrain, geology, or altitude. This is the first study using a new, high-resolution airborne, chemical-detecting instrument to map multiple ecosystem chemicals. The result, published in the April 8, 2013, Early Edition of the Proceedings of the National Academy of Sciences, is a key step toward understanding how...

Forest Soil Traps More Carbon Than Thought
2013-04-01 14:02:36

Brett Smith for redOrbit.com — Your Universe Online The planting and expansion of forests not only allows for the trapping of carbon in the trees themselves, it also fosters carbon absorption in the soil where the trees are rooted. Previous studies have shown that more carbon is sequestered in forest soils that in the trees, but according to new research in“¯the“¯Soil Science Society of America Journal, newly forested lands show a marked increase in carbon...

Decreased Water Flow May Allow For More Productive Forest
2013-03-25 16:22:39

Northern Research Station - USDA Forest Service Bubbling brooks and streams are a scenic and much loved feature of forest ecosystems, but long-term data at the U.S. Forest Service´s Hubbard Brook Experimental Forest suggests that more productive forests might carry considerably less water, according to a study published today in the journal Proceedings of the National Academy of Sciences. Mark Green, a research hydrologist with the Forest Service´s Northern Research Station...

A new forum paper suggests bridging two important fields of ecological research It is increasingly recognized that protected areas alone are not sufficient for successful biodiversity conservation, and that management of production areas (e.g. forestry and agricultural land) plays a crucial role in that respect. Retention forestry and agroforestry are two land management systems aiming to reconcile the production of human goods with biodiversity conservation. The retention forestry...

Jurassic Records Warn Of Risk From Global Warming On Marine Life
2013-02-19 14:08:45

Plymouth University Researchers at Plymouth University, UK, believe that findings from fieldwork along the North Yorkshire coast reveal strong parallels between the Early Jurassic era of 180 million years ago and current climate predictions over the next century. Through geology and palaeontology, they've shown how higher temperatures and lower oxygen levels caused drastic changes to marine communities, and that while the Jurassic seas eventually recovered from the effects of global...

Plant Biodiversity Protects Ecosystems From Human Perils
2013-02-07 08:59:14

April Flowers for redOrbit.com - Your Universe Online A new study led by integrative biologists at the University of Guelph warns of the perils inherent in an ecosystem breakdown. The findings of the study, which appeared as the cover story in today´s issue of the journal Nature, suggest that resource managers and farmers should not rely on single crop monocultures, no matter how stable they may appear to be. The team suggests instead that farmers should cultivate the growth of more...

There Is A Limit For How Long Plants Can Adapt To Drought
2013-01-23 13:50:15

University of Arizona Plants can adapt their demand for water depending on how much is available - However, this resilience has a limit, and prolonged drought conditions threaten the survival of plant communities, especially in more arid areas Scientists with the U.S. Department of Agriculture, or USDA, and their partners have determined that water demand by many plant communities can fluctuate in response to water availability, indicating a capacity for resilience even when changing...

A research team involving several scientists from the University of Colorado Boulder has found an unexpected silver lining in the devastating pine beetle outbreaks ravaging the West: Such events do not harm water quality in adjacent streams as scientists had previously believed. According to CU-Boulder team member Professor William Lewis, the new study shows that smaller trees and other vegetation that survive pine beetle invasions along waterways increase their uptake of nitrate, a common...

Australian Wildfires Continue Despite Cooler Temps
2013-01-09 08:53:36

redOrbit Staff & Wire Reports - Your Universe Online Despite cooler conditions across southeastern Australia on Wednesday, the threat of wildfires remained a concern throughout the states of New South Wales, Victoria and Tasmania, according to various news reports. Record heat and dry conditions sparked bushfires throughout several regions in recent days, destroying buildings throughout all three Australian states, according to BBC News. The Associated Press (AP) notes that there...

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...
