Canis lupus Conservation policy
a b s t r a c t The wolf (Canis lupus) population on Isle Royale, a remote island in Lake Superior, North America, is extre-mely inbred. Nevertheless, the consequences of genetic deterioration have not been detected for this intensively studied population, until now. We found that 58 % (n = 36) of I...
