Inbreeding Depression in a Captive Wolf ( Canis lupus ) Population
Abstract. Uncertainty currently exists regarding the extent to which mammalian carnivores suffer from inbreeding depression. In particular, it has been proposed that wolves and species with a similar social structure are adapted to close inbreeding. Empirical data, however, are scarce. This paper pr...
