The endangered North Atlantic right whale faces increased odds because its main food supply has shifted due to ocean warming, according to new research. Scientists have been searching for an explanation for a precipitous decline in the North Atlantic right whale population, which has dropped from 482 in 2010 to about 411 today. As the food supply moved in response to ocean warming so did the whales, apparently putting them closer to shipping lanes and fishing locations that had been designed to avoid the whales’ usual feeding grounds. Whales also faced traveling farther for food and feeding earlier in the year, leaving them more hungry than usual before winter.
