Inbreeding Depression in a Captive Wolf (Canis lupus) Population

摘要: . 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 close inbreeding. Empirical data, however, scarce. This paper provides strong evidence against contention natural populations of resistant We analyzed studbook data captive wolf population bred in Scandinavian zoos found negative effects expressed as reductions juvenile weight, reproduction, longevity. The occurrence an apparently bereditary form blindness is also associated Different can be attributed genes originating different founder pairs, thus indicating alleles deleterious homozygous state fairly common populations. Resumen: Actualmente hay incertidumbre en relacidn a1 nivel que los nuzmms earninnos sufren depresidn por la cruza consanguinea En lobos y las especies con una estructura han sido ppuestos como adaptados para el cruzamiento consanguineo cercano.
