Musculoskeletal mass and shape are correlated with competitive ability in male house mice (Mus musculus)

Amanda Cooper, Christopher Cunningham, Jeremy Morris, James Ruff, Wayne Potts & David Carrier
Intense physical competition between males for mating opportunities is widespread among mammals. In such agonistic encounters, males with combinations of morphological, physiological, and behavioral characters that allow them to dominate an opponent often have greater fitness. However, the specific physical traits associated with competitive ability are poorly understood. Larger body size is often correlated with fitness in mammals. Interestingly, fitness is maximized at intermediate body masses in male house mice (Mus musculus), a species with...
