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…

There may be valid reasons to thin forests – such as restoration of forest structure or health, wildlife enhancement or public safety – but increased carbon…
One consequence of this is that the climate may be more sensitive to emissions caused by human activity than we have previously believed. Scientists at the…
When a plant encounters drought, it does its best to cope with this stress by activating a set of protein molecules called receptors. These receptors, once…
