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…

Tembin moved through the Myeongnyang Strait and made landfall on Aug. 30, 2012 at 0000 UTC (Aug. 29 at 8 p.m. EDT) in the southwestern tip of South Korea. NASA's Aqua satellite's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a visible, true-color image of Tropical Storm Tembin around the time of landfall in southwestern South Korea. The image was captured at 04:45 UTC (12:45 a.m. EDT) on Aug. 30, and showed an elongated storm stretching from southwestern South Korea, over North Korea and into the Sea of Japan. Southwesterly wind shear has also taken its toll on Tembin as the storm has become elongated. When a storm is no longer circular, it loses its energy….
