Shaking the myth: Body mass, aggression, steroid hormones, and social dominance in wild house mouse

Highlights • Body mass predicts social rank only in the more aggressive M. m. domesticus mice. • Less aggressive M. m. musculus mice invest more into accelerated sexual maturation. • Paradigm of direct causality testosterone → violence → stress may not be universal. • Limited aggression in M. m. mus...

Description
Summary:Highlights • Body mass predicts social rank only in the more aggressive M. m. domesticus mice. • Less aggressive M. m. musculus mice invest more into accelerated sexual maturation. • Paradigm of direct causality testosterone → violence → stress may not be universal. • Limited aggression in M. m. musculus is outweighed by prolonged stress period. • Closely related taxa differ significantly in establishing of social rank settings.
