Isle Royale wolves were rebuilt from 19 animals, and one brother-and-sister pair produced at least 12 pups, yet a five-year study still gives the population a better than 80 percent chance of lasting 20 years
From Eco News:
Ten years ago there were just two Isle Royale wolves left, a father and daughter who were also half-siblings, and they weren’t having pups.
Now there are about 37 wolves on the island, and a new study says they have a better than 80 percent chance of making it another 20 years, even though they’re inbred.
