The range of the red wolf used to extend from Mexico into the eastern US. But decades of hunting by humans, habitat loss, and other factors nearly wiped them out, and wild red wolves were declared extinct in 1980. Yet surprisingly, part of their genome is preserved in a pack of canines living on Galveston Island in Texas, researchers reported December 10 in the journal Genes.
“It’s incredibly rare to rediscover animals in a region where they were thought to be extinct, and it’s even more exciting to show that a piece of an endangered genome has been preserved in the wild,” says one of the study’s authors, Elizabeth Heppenheimer, in a statement.
In the 1970s, the US Fish and Wildlife service captured wild red wolves to start a captive breeding program. After red wolves were declared extinct in the wild, some of the animals bred in captivity were reintroduced ...
