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…
Using little more than PVC rings, a trashcan, and a scale, students can literally get a feel for soil water retention and field capacity, concepts that are…
Agricultural Research Service (ARS) physiologist Marta D. Van Loan and other researchers learned more about these compounds in a 3-year study–the longest of…

The theory suggests that the energy necessary to produce the magnitude 7-7.5 earthquakes came from stored stress built up in the Earth's crust long ago. Rapid…
In this time of global change, understanding the basics of animal behavior and environmental interactions is just as important as predicting and planning for…
Black carbons — arising from such sources as diesel engine exhaust and cooking fires — are widely considered a factor in global warming and are an important…
Using a statistical analysis of chemicals found in walleye ear bones, the researchers were able to calculate the percentage of walleye hatched in the Sandusky…
The study shows that soot is second only to carbon dioxide in contributing to global warming. But, climate models to date have mischaracterized the effects of…
“One of the great longstanding mysteries about hurricanes is how they form,” says Christopher Davis, a scientist with the National Center for Atmospheric…
The Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association for the first time sent its Autonomous Underwater Vehicle (AUV) on an…
Switchgrass is now grown as a cattle feed and to restore depleted soils. But interest in using it as a biofuel has intensified in recent years because it can…
Experts from the university's School of Agriculture, Food and Rural Development have shown for the first time that a pig's mood mirrors how content he is,…
