As wild areas become more and more developed, roads and other structures fragment wildlife populations. Animals find it harder and harder to come across new mates that will keep genetic diversity high. Recently it has been found that bear populations, at least, are using wildlife crossings like underpasses to find new mates. Montana State University researchers compared genetics of bear populations in the Canadian Rockies. Their study resulted in the first proof that these crossings can maintain the genetic diversity. This is excellent news for wildlife and the humans that love them!
