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...

Overgrazing Is Turning Parts Of Mongolian Steppe Into Desert
2013-09-06 13:27:48

Oregon State University Overgrazing by millions of sheep and goats is the primary cause of degraded land in the Mongolian Steppe, one of the largest remaining grassland ecosystems in the world, Oregon State University researchers say in a new report. Using a new satellite-based vegetation monitoring system, researchers found that about 12 percent of the biomass has disappeared in this country that’s more than twice the size of Texas, and 70 percent of the grassland ecosystem is now...

Researchers Identify Unprotected Regions That Harbor The Majority Of Life On Earth
2013-09-05 16:23:48

American Association for the Advancement of Science Can the separate international commitments of protecting 17% of the planet's terrestrial surface and of conserving 60% of the world's plant species within these protected areas be met simultaneously by 2020? A new study suggests that they can—but only if researchers and conservationists do more to safeguard particularly hot spots of biodiversity. According to Lucas Joppa from Microsoft Research in Cambridge, England, and colleagues...

Understanding Desert Plant Migration
2013-08-30 13:24:31

Michael Harper for redOrbit.com - Your Universe Online New research shows that greater plant density allows more water to seep into the ground. This means that people living in dry climates where water is a limited resource could do well to plant dense patches of vegetation to allow more water into the ground. This research also explains why plants in semiarid and dry climates often grow in tight clusters and long bands across the soil. In his paper, which was published last month in...

Dragonfly Study Shows How Ecosystem Changes Affect Biodiversity
2013-08-14 07:22:29

April Flowers for redOrbit.com - Your Universe Online Rice University researchers have found that communities in nature are likely to be a lot more sensitive to change than previously thought. The study findings, published in Nature Communications, points to a need for scientists concerned with human impact on the biosphere to take a different look at the consequences of altering the dynamics of a population. One example of such alteration would be removing large members of a species...

FLAGSTAFF, Ariz., Aug. 6, 2013 /PRNewswire/ -- Forests have a limited capacity to soak up atmospheric carbon dioxide (CO2), according to a new study from Northern Arizona University. The study, available online in the journal New Phytologist, aimed to explore how rising atmospheric carbon dioxide could alter the carbon (C) and nitrogen (N) content of ecosystems. By performing tests on subtropical woodland plots over an 11-year period, the researchers found that ecosystem carbon...

New System For Early Detection Of Plant Spread In Bodies Of Water
2013-08-01 10:23:09

Technical University Munich As a result of climate change, certain undesirable aquatic plants are starting to invade German water bodies. Even popular recreation areas like Lake Starnberg have been affected, leading to a growing need to monitor the spread of these plants. Up to now, regular monitoring has proven to be a costly process. But in a new approach, researchers at Technische Universitat Munchen (TUM) have developed a quicker and less expensive method. Taking a dip in a...

Wildlife Conservation Society study finds impending economic growth and climate change impacts require long-term adaptation efforts to conserve Myanmar's unique biodiversity Long isolated by economic and political sanctions, Myanmar returns to the international community amid high expectations and challenges associated with protecting the country's great natural wealth from the impacts of economic growth and climate change. In a new study, scientists from the Wildlife Conservation...

New research from the University of Guelph, published Tuesday in the journal Biodiversity and Conservation, says that allowing industrial extraction in a northern Ontario old-growth red pine forest – the largest remaining in the world – would significantly threaten biodiversity in Canada. The study says Wolf Lake Forest Reserve is a “scientifically irreplaceable system.” “Wolf Lake Forest deserves intensive study, monitoring and full protection from future development,” said...
