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…

Tropical Cyclone 16S has already powered up into a tropical storm, and is headed in the direction of Port Louis and Reunion Island in the next couple of days.At 10 a.m. ET (1500 UTC) on February 16, Tropical Storm 16S (TS 16S)) had maximum sustained winds near 52 mph (45 knots). It was about 575 nautical miles north-northeast of La Reunion Island, near 13.1 South and 60.6 East, so it has a good way to go before affecting the island. It was moving south at 9 mph (8 knots). …
