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...

Provides scientists and policymakers with insights for selecting and managing conservation areas How can a square meter of meadow contain tens of species of plants? And what factors determine the number of species that live in an ecosystem? Science journal has defined this as one of the 25 most important unresolved questions in science, both for its importance in understanding nature and due to the value of natural ecosystems for mankind. The value of goods and services provided by natural...

Amazon Deforestation Threatens Microbial Life
2012-12-25 05:22:39

April Flowers for redOrbit.com - Your Universe Online A troubling loss of diversity among the microbial organisms responsible for a functioning ecosystem is accompanying deforestation in the Amazon rainforest, an international team of microbiologists led by the University of Massachusetts, Amherst, has discovered. "We found that after rainforest conversion to agricultural pastures, bacterial communities were significantly different from those of forest soils. Not only did the pasture...

Climate Change Is Having Major Impact On Biodiversity
2012-12-20 14:38:33

redOrbit Staff & Wire Reports - Your Universe Online Global warming is causing plant and animal species to alter their geographic ranges and the timing of key life events such as migrating, flowering, or laying eggs -- a shift that could adversely impact biodiversity as well as ecosystems, a new government report has revealed. The range and timing-related changes are occurring faster now that they were just a few years ago, report the authors of "Impacts of Climate Change on...

As digital cameras become better and cheaper, ecologists are turning these ubiquitous consumer devices into scientific tools to study how forests are responding to climate change. And, they say, digital cameras could be a cost-effective way of visually monitoring the spread of tree diseases. The results — which come from 38,000 photographs — are presented at this week's British Ecological Society's Annual Meeting at the University of Birmingham. Because trees fix carbon dioxide...

Great Lakes Study Highlights Environmental Threats And Challenges
2012-12-18 09:46:53

April Flowers for redOrbit.com - Your Universe Online A research team, led by the University of Michigan, has developed a comprehensive map telling the story of human impact on the Great Lakes and identifying how "environmental stressors" stretching from Minnesota to Ontario are shaping the future of an ecosystem that contains 20 percent of the world's fresh water. The map, three years in the making, was a collaborative effort with the University of Wisconsin-Madison and a binational team...

Climate Change Threatens Cloud Forest Ecosystem
2012-12-14 08:32:14

April Flowers for redOrbit.com - Your Universe Online A research team from the University of California, Berkeley, has discovered that tropical montane cloud forest trees drink water from clouds, directly through their leaves. There is just one small problem with this fact, the clouds necessary for the trees survival are disappearing due to climate change. Declines and disappearances of cloud forest animals such as frogs and salamanders have already been correlated to changes in cloud...

Fish Have Huge Nutrient Impacts On Marine Ecosystems
2012-12-12 09:33:47

University of Georgia Fish play a far more important role as contributors of nutrients to marine ecosystems than previously thought, according to researchers at the University of Georgia and Florida International University. In a pair of papers in the journal Ecology, they show that fish contribute more nutrients to their local ecosystems than any other source-enough to cause changes in the growth rates of the organisms at the base of the food web. Jacob Allgeier, a doctoral student 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
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...
