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...

Article in Science magazine by University of Nevada, Reno and University of Iowa shows research result New regulatory approaches may be needed to assess environmental risks of agricultural growth promoters, and similar human pharmaceuticals, following research that shows a newly found reversion mechanism allows unexpected persistence of the steroidal substances in aquatic environments. Results of the research will be published in an article in the renowned journal Science – the weekly...

Armageddon For Wildlife In Shrinking Rainforests
2013-09-27 04:31:22

April Flowers for redOrbit.com - Your Universe Online An international team of scientists reveals that species living in rainforest fragments could be far more likely to disappear than was previously thought. The scope of the two decade study, published in the journal Science, allowed the researchers to witness the near-complete extinction of native small mammals on forest islands created by a large hydroelectric reservoir in Thailand. "It was like ecological Armageddon," said Luke...

World's Forests Moving Uphill

Brett Smith for redOrbit.com - Your Universe Online A relaxing stroll through the woods is increasingly becoming an intense cardiovascular workout, as a new report from researchers at Aarhaus University in Denmark indicates that that the world’s forests are slowly being relegated to steep, mountainous slopes. According to study author Brody Sandel, the increasingly efficient removal of trees from flat areas around the world raises concerns about the biodiversity of the world's forests...

Peru Cloud Forests Threatened
2013-09-12 12:13:07

Brett Smith for redOrbit.com - Your Universe Online According to a new study from Wake Forest University published by the journal PLOS ONE, a confluence of climate change and ecological factors could threaten Peru’s cloud forests, which are nestled along the eastern slopes of the Andes Mountains. Home to one third of Peru's mammal, bird and frog species, the cloud forests are renowned for their biodiversity and high elevation. At altitudes between 6,500 and 11,000 feet, they are a...

NASA The Wallow Fire burned over 500,000 acres, making it the largest fire in Arizona history, to date. It is one of many large fires that fire managers and researchers have seen scorch forests nationwide since the early 2000s. "We have entered a new era where we're definitely seeing higher fire activity,” said Philip Dennison, a geographer at the University of Utah in Salt Lake City. With busy fire seasons, scientists and fire managers are interested in how and why fire frequency,...

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...
