Morphological variation and allometry of the baculum in stoats, Mustela erminea (Carnivora, Mustelidae) from Western Carpathians

In this study we investigated allometry and variation in the baculum of the stoat Mustela erminea and compared it with head-and-body length not involved in reproduction. The stoat is a species with pre-copulatory selection (manifested by the high degree of male-biased sexual size dimorphism) therefore we predicted that baculum allometry may be isometric or exhibited negative allometry. We also test the hypothesis that the baculum...
