Endangered orcas are losing their unborn babies because they’re starving, study finds

A unique group of killer whales is miscarrying at an astronomical rate, and it’s because humans have wiped out most of their food supply.   A recent study in the journal PLOS ONE found that as high as 69 percent of Southern Resident killer whale pregnancies end in failure. These famous whales, which frequent the Salish Sea off Seattle and Vancouver, rely on Chinook salmon for the lion’s share of their diet. Once abundant, Chinook are now rare and the whales are going hungry. The study is the first to demonstrate a clear link between orca miscarriage and poor nutrition brought on by the scarcity of their main prey. Scientists at the University of Washington collected orca feces between 2008 and 2014 to measure hormones that regulate hunger, stress and reproduction. DNA profiling let them track the stages of pregnancy for individual orcas, and figure out when a female became pregnant and at what...

Rising temperatures are cooking baby sea turtles in their nests

Baby sea turtles face a famous gauntlet. The little reptiles are vulnerable to predators, poachers, fishing gear and plastics. And now with climate change, there’s one more hurdle on that list: unusually hot sand. Scorching sand heats up turtle nests, which are buried in pits on beaches. Those elevated temperatures can cook developing embryos. “In some places the nests are getting so hot that there’s no survival,” says marine biologist Kristin Mazzarella of Mote Marine Lab in Sarasota, Florida. “The eggs don't hatch.”   In the short term, most turtle species can cope with a little extra warmth. But in the long game, overheating nests could be a serious burn for these ancient ocean reptiles. Turtles in trouble Lately beaches have been getting hotter, thanks to man-made climate change. Warming is projected to continue into the next century, heating up beaches around the world. Sea turtles will keep nesting along...
