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…

Climate change has accelerated sea-ice retreat in the Arctic Ocean. This has various negative impacts including acidification of ocean water and potential…
The Amazon rainforest is the largest forest on earth. Its trees emit huge amounts of volatile substances that influence the chemical composition of the air….
The findings about past ocean changes could also have implications for how much atmospheric CO2 will rise due to fossil fuel burning.
Atmospheric derived mercury is transformed in the ocean to toxic methylmercury, which is enriched in fish. Large marine predators such as tuna are strongly…
The long-dormant Yellowstone super-volcano in the American West has a different history than previously thought, according to a new study by a Virginia Tech…
A new study shows that as those fires scorched a region of boreal forest the size of Maryland, they released half as much carbon back into the atmosphere as…
