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…

The finding could help scientists predict when Hawaiian volcanoes are going to erupt. It also suggests that Hawaii holds great potential for thermal energy.Julie Ditkof, an honors undergraduate student in earth sciences at Ohio State, described the study at the American Geophysical Union Meeting in San Francisco on Tuesday, December 14….
“Our study shows that regardless of rainfall going up or down, forests in the Southwest U.S. are very sensitive to temperature –– in fact, more sensitive than…
Summer land surface temperatures of cities in the Northeast were an average of 13°F to 16°F (7°C to 9°C) warmer than surrounding rural areas over a three year…
