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…
