The genetic secret helping bats survive a deadly epidemic
Conservation biologists have identified genetic mutations in little brown bats that may help them survive white-nose syndrome. This discovery provides insights into how natural selection is responding to the deadly epidemic and could guide future conservation strategies.
Why it matters
Understanding the genetic basis of survival in wildlife can help prevent the extinction of species facing environmental threats.
We're easing you into Halloween season with an episode about bats . There's a silent serial killer decimating little brown bats as they hibernate. White nose syndrome has driven populations across the U.S. to almost the brink of extinction over the last decade. But recently, conservation biologist Giorgia Auteri and her team noticed several genetic mutations in the survivors. These mutations could explain how natural selection has shifted the existing population – and inform conservation efforts in the future.
