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…

Last year, for instance, China restricted the export of neodymium, which is used in wind generators. The move was ostensibly to direct the supplies to toward a…
Snaggle-toothed ichthyosaurs larger than school buses swam at the top of the Triassic Period ocean food chain, or so it seemed before Mount Holyoke College…
While the cause of the mass extinction that occurred between the Permian and Triassic periods is still uncertain, two University of Rhode Island researchers…
The three-year study will determine what specific conditions and fishy behaviors are supporting the goliath grouper’s population recovery in the Atlantic Ocean…
Cultivars of popular ornamental woody plants that are being sold in the United States as non-invasive are probably anything but, according to an analysis by…

The eleventh tropical depression quickly grew into Tropical Storm Irwin this morning, as strong convection surged around its center of circulation. That…
The wind shear lessened, and Philippe became a hurricane today, after 12 days of moving across the Atlantic Ocean. NASA's TRMM satellite saw towering…
Not far from the ancient shore of Lake Agassiz, University of Cincinnati Professor of Geology Thomas Lowell will present a paper about the lake to the…
This finding, made onboard the NOAA ship Okeanos Explorer in the Gulf of Mexico, will lead to more effective mapping of these gas seeps and, ultimately,…
Scientists of the Potsdam Institute for Climate Impact Research (PIK) have now identified the scale of danger for animals and plants in a worldwide analysis.For that purpose, they developed a novel measure that for the first time systematically quantifies the impacts of changes in CO2 concentration in the air as well as in temperature and rainfall on terrestrial ecosystems. Computer simulations show that global warming could lead to an expansion of the Kazakh steppe but also lets forests grow in the presently treeless tundra….
This longstanding mystery is addressed in a review by the University of Zurich’s Michael Schmidt, Susan Trumbore from Max Planck Institute of Biogeochemistry…
After the oceans, the humus is the largest carbon reservoir. If the humus decreases, additional CO2 gets into the atmosphere. A research team headed by the…
TRMM measured the rainfall rates in Nalgae on October 4, 2011 at 0624 UTC (2:24 a.m. EDT). The rainfall analysis from TRMM's Microwave Imager (TMI) and…
