A long-term study verifies multi-paddock grazing improves vegetation, soil health and animal production relative to continuous grazing in large-scale ranches, according to Texas AgriLife Research scientists. The study measured the impacts on vegetation and soils achieved by commercial ranchers who adapted management practices in response to changing circumstances to achieve desirable outcomes, said Dr. Richard Teague, AgriLife Research rangeland ecology and management scientist in Vernon. At...

An ecosystem is like a great organism in that the species in it behave in a manner similar to the manner in which cells behave within the human body: the group forms a permanent entity, although the entities that form it are constantly being substituted. This is the conclusion that can be drawn from a theoretical study carried out by researchers at the Universidad Carlos III de Madrid (UC3M "“ Carlos III University of Madrid). These scientists have developed a mathematical model that...

Researchers eavesdropping on complex signals from a remote Wisconsin lake have detected what they say is an unmistakable warning--a death knell--of the impending collapse of the lake's aquatic ecosystem. The finding, reported April 28 in the journal Science by a team of researchers led by Stephen Carpenter, an ecologist at the University of Wisconsin-Madison (UW-Madison), is the first experimental evidence that radical change in an ecosystem can be detected in advance, possibly in time to...

Researchers eavesdropping on complex signals emanating from a remote Wisconsin lake have detected what they say is an unmistakable warning "” a death knell "” of the impending collapse of the lake's aquatic ecosystem. The finding, reported today (April 29) in the journal Science by a team of researchers led by Stephen Carpenter, a limnologist at the University of Wisconsin-Madison, is the first experimental evidence that radical change in an ecosystem can be detected in advance,...

A new paper appearing in the Proceedings of the National Academy of Sciences (PNAS) suggests that people, governments, and institutions that shape the way people interact may be just as important for determining environmental conditions as the environmental processes themselves. "Tipping points," qualitative changes in an ecosystem that often result in reduced ecosystem health and are difficult and costly to reverse increasingly concern environmental scientists. The prevailing assumption...

Scientists studied the global influence of human population on corals reefs and were surprised to find that highly diverse reef fish systems are the most vulnerable to human threats In an unprecedented collaborative analysis published in the journal PLoS Biology, scientists from 49 nations demonstrated that the ability of reef fish systems to produce goods and services to humanity increases rapidly with the number of species. However, growing human populations hamper the ability of reefs to...

By Lily Whiteman, National Science Foundation Newly discovered ancient, mummified trees may reveal clues about future ecosystem responses to climate change When in Quttinirpaaq National Park in the Canadian Arctic, Ohio State University Earth scientist Joel Barker initially spotted some pieces of dead trees scattered on the barren ground near a glacier. Immediately, he knew he had found something akin to a looking glass peering into the Arctic's ecological past. The Hazen Plateau on Ellesmere...
