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...

Earth’s Large Old Trees Are Dying Off
2012-12-07 14:14:00

Brett Smith for redOrbit.com - Your Universe Online According to a new study by a trio of Australian and American researchers, large, old trees, which provide shelter for a multitude of animals, are declining in record numbers around the world. “It´s a worldwide problem and appears to be happening in most types of forest,” said lead author David Lindenmayer, an environmentalist with the Australian National University. “It is a very, very disturbing trend. We...

While science has often focused on big-scale, global climate change research, a study recently released in the journal Bioscience suggests that long-term, integrated and site-specific research is needed to understand how climate change affects multiple components of ecosystem structure and function, sometimes in surprising ways. “Long-term ecological research is important to understanding the effects of a changing climate on our natural resources and so much more,” said Michael...

Revolutionary Biosphere Mapping Capability Announced At AGU
2012-12-04 17:15:55

Carnegie Institution Researchers from the Carnegie Institution are rolling out results from the new Airborne Taxonomic Mapping System, or AToMS, for the first time at the American Geophysical Union (AGU) meetings in San Francisco. The groundbreaking technology and its scientific observations are uncovering a previously invisible ecological world. To watch a video about how AToMS is helping researchers look at the world in a whole new way, click here. AToMS, which launched in June 2011,...

Around the world, the effects of global climate change are increasingly evident and difficult to ignore. However, evaluations of the local effects of climate change are often confounded by natural and human induced factors that overshadow the effects of changes in climate on ecosystems. In the December issue of the journal BioScience, a group of scientists writing on long-term studies of watershed and natural elevation gradients at the Hubbard Brook Experimental Forest in New Hampshire and 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...
