New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…
“It used to be very difficult to detect which chronic effects occur,” explains Dr Matthias Liess, head of the UFZ's System Ecotoxicology Department. In their…
In order to foresee the appearance of desertification processes, defined by the United Nations as the “degradation of the land into arid, semi-arid and…
Kudzu, the fast-growing vine that has gobbled up some 10 million acres in the Southeast, may prove to be a valuable dietary supplement for metabolic syndrome,…
The international study, led by Northern Arizona University and the National Center for Atmospheric Research (NCAR), will be published in the September 4…
High northern latitudes have experienced a long-term, slow cooling trend for several millennia, the result of a wobble in Earth's rotation that has been…
An international team of scientists, led by Darrell Kaufman, a Northern Arizona University professor of geology and environmental science, recently completed a…
Topology and weather are also factors. Regarding the Station fire in California, Zedaker said that because of the 40-years of buildup of tinder dry fuel, “If…
Conservation biologists based in four countries gathered for an emergency meeting in Vientiane, Lao PDR, August 19, to address the peril of extinction facing…
One way to maximize the eco-friendly factor of a structure is to include a green roof—and this doesn't refer to the paint color. “Greening” a roof, or covering…
While growers have used soil moisture probes to aid in irrigation management in the past, earlier probes required maintenance or were expensive or inadequate. New electronic sensors have been developed that require minimal maintenance and are more affordable. This study evaluated and developed calibration information for one of the newer probes. These probes can be placed at different depths in the soil and show growers how deep water has moved….
Europe's first farmers replaced their Stone-Age hunter-gatherer forerunners: Analysis of ancient DNA from skeletons suggests that Europe's first farmers were…

Warming from greenhouse gases has trumped the Arctic's millennia-long natural cooling cycle, suggests new research. Although the Arctic has been receiving less…
An MIT paper appearing in the Journal of Geophysical Research online Aug. 29 elucidates how this underground methane in frozen regions would escape and also…
Researchers from the Helmholtz Centre for Environmental Research (UFZ) have developed a tool that can estimate the harmful effect of pesticides, such as those flushed into rivers and streams from agricultural land, within minutes. "It used to be very difficult to detect which chronic effects occur," explains Dr Matthias Liess, head of the UFZ’s System Ecotoxicology Department.In their new approach, the Helmholtz researchers exploit the fact that pesticides cause characteristic changes to the composition of the life community that is…
