Following a recent spike in Bering Sea killer whale entanglements, a simple addition to fishing nets has delivered positive early results for keeping the big marine mammals out of deep-water flatfish trawls. The net modification was developed through a collaboration between University of Alaska Fairbanks researcher Hannah Myers and the Alaska Seafood Cooperative, which coordinates […]
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 […]
By evaluating historical climate records, observational and projection data, an international team of researchers found a “pushing and triggering” mechanism that has driven the Arctic climate system to a new state, which will likely see consistently increased frequency and intensity of extreme events across all system components – the atmosphere, ocean and cryosphere – this […]
