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…

“It is surprising to have large, potentially complex fossils that far back,” said Christopher H. House, professor of geosciences, Penn State, and lead author.However, the researchers not only showed that these inclusions in the rocks were biological in origin, but also that they were likely planktonic autotrophs — free-floating, tiny ocean organisms that produce energy from their environment. …
