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…
Pines close to treeline have wider annual growth rings for the period from1951 to 2000 than for the previous 3,700 years, reports a University of Arizona-led…
Since 1985, surface water temperatures measured by lake buoys have climbed 1.2 degrees per decade, about 15 percent faster than the air above the lake and…
The pervasive incidence of arsenic poisoning in Bangladesh and its link to drinking water were first identified in the scientific literature in the early…
Polar 5 will be used in three research programmes in the season 2009/10 and it will logistically support the established Antarctic flight network DROMLAN…
“Climate change is making itself felt in terms of day-to-day weather in the United States,” says NCAR scientist Gerald Meehl, the lead author. “The ways these…
The valley was created by glaciers and over time filled with loose rock gradually disappearing from the landscape. There had already been extensive underground…
Mike Tice, a researcher in the Department of Geology and Geophysics at Texas A&M, says the findings could change current ideas about the earliest forms of life…
Sunspots, which rotate around the sun's surface, tell us a great deal about our own planet. Scientists rely on them, for instance, to measure the sun's…
The ratio of record highs to lows is likely to increase dramatically in coming decades if emissions of greenhouse gases continue to climb.”Climate change is…
This mass loss is equally distributed between increased iceberg production, driven by acceleration of Greenland's fast-flowing outlet glaciers, and increased…
Long-term variations in volcanism help explain the birth, evolution and death of striking geological features called oceanic core complexes on the ocean floor,…
The calculation of variations in the sea level is relatively simple. It is by far more complicated to then determine the change in the water mass. A team of…
A researcher from North Carolina State University has developed an innovative water management framework that would take advantage of these forecasts to plan…
Regulations and guidelines for tolerable concentrations of these potentially plant-toxic elements in soils are based on the assumption that the toxic effects…
With funding from National Geographic Society's Committee for Research and Exploration, and with support from Western Illinois' College of Arts and Sciences…
This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected. The results run contrary…
