Scientists address climate change effects on ecosystems from grasslands to forests to open ocean Human activities such as burning of fossil fuels and land use change have increased atmospheric carbon dioxide by 40 percent since the start of the industrial revolution, researchers have found. The result is a hotter Earth, with warmer average temperatures around the globe and a future climate system that will be more variable, and with more extreme events, says Scott Collins, a scientist at the...

When engineers restore rivers, one Kansas State University professor hopes they'll keep a smaller engineer in mind: the North American beaver. Beavers are often called ecosystem engineers because they can radically alter stream or valley bottom ecosystems, said Melinda Daniels, an associate professor of geography who recently studied the connection between beavers and river restoration. Beaver dams create diverse river landscapes, she said, and can turn a single-thread channel stream into a...

Discoveries spanning five continents and three oceans cap the United Nations' International Year of Biodiversity Global biodiversity surveys over the past few years have provided increasing evidence that our planet is in the midst of its sixth mass extinction. Plants, animals, and microorganisms are disappearing thousands of times more rapidly than they have for more than 65 million years, and for the first time in Earth's history, human activity is the predominant force behind this mass...

Unique open-air laboratory enables study of a complete ecosystem in the making How do ecosystems develop? No one really knows, yet. There is however one project, unique in the world, seeking to answer this question. In a former open-pit coal mining area in Brandenburg, Germany, a surface of six hectares was partitioned off and then left to its own resources. Scientists from the Technische Universitaet Muenchen (TUM), in collaboration with researchers from other institutions, are studying the...

Region urged to invest in sustainable use of key sectors to lead world's ecosystem services markets Mar del Plata, Argentina (Vocus/PRWEB) December 02, 2010 An extraordinary array of goods and services provided by the rich plant and wildlife of Latin America and the Caribbean hangs in the balance unless governments in the region take hold of their full potential as biodiversity superpowers, according to a new report from the United Nations Development Programme (UNDP). The report,...

Ecologists say prior studies underestimated the specific dietary needs of most species Children aren't the only youngsters who are picky eaters: More than half of all species are believed to change their diets -- sometimes more than once -- between birth and adulthood. And a new study by ecologists at Rice University and the University of California, Santa Barbara, finds this pattern has major implications for the survival of threatened species and the stability of natural ecosystems. With...

Inaccurate conclusions may have been reached in many ecosystems The most widely adopted measure for assessing the state of the world's oceans and fisheries led to inaccurate conclusions in nearly half the ecosystems where it was applied. The new analysis was performed by an international team of fisheries scientists, and is reported in this week's issue of the journal Nature. "Applied to individual ecosystems it's like flipping a coin; half the time you get the right answer and half the time...

The most widely adopted measure for assessing the state of the world's oceans and fisheries led to inaccurate conclusions in nearly half the ecosystems where it was applied according to new analysis by an international team led by a University of Washington fisheries scientist. "Applied to individual ecosystems it's like flipping a coin, half the time you get the right answer and half the time you get the wrong answer," said Trevor Branch, a UW assistant professor of aquatic and fishery...

On the rocks just beneath the tides, the faster the water is moving in an area, the greater the variety of invertebrate creatures that will live there. Understanding that water flow is a strong predictor of diversity could be a huge boon to efforts to manage coastal ecosystems. One of biggest factors promoting the diversity of coastal ocean life is how fast the water flows, according to new research by ecologists at Brown University. Experiments and observation in Palau, Alaska, and Maine...

A first-of-its-kind red list of globally threatened ecosystems has the potential to complement the policy successes of the IUCN Red List of Threatened Species, according to a recent article led by EcoHealth Alliance's Jon Paul Rodriguez NEW YORK, Nov. 9, 2010 /PRNewswire-USNewswire/ -- A recent article by a group of 21 scientists led by Jon Paul Rodriguez, a local conservation partner of EcoHealth Alliance, formerly known as Wildlife Trust, sheds light on the urgent need for...
