摘要: Recent genetic studies suggest that in northern Minnesota two species of wolves (Canis lupus L., 1758 or western wolf and Canis lycaon Schreber, 1775 (= rufus Audubon Bachman, 1851) eastern wolf) meet hybridize. However, little morphological information is available about these types Minnesota. We analyzed the mass 950 female 1006 males older than 1 year from across found it increased 26.30 ± 0.56 kg (mean ± SE) for females 30.60 ± 0.72 kg northeastern to 30.01 ± 0.43 kg 35.94 ± 0.45 kg northwestern (females: r2 = 0.79, P < 0.02; males: 0.63, P 0.06). These differences add identities support view ranges
