A test of Rensch's rule in greater horseshoe bat (Rhinolophus ferrumequinum) with female-biased sexual size dimorphism.

Sexual size dimorphism (SSD) is widespread within the animal kingdom. Rensch's rule describes a relationship between SSD and body size: SSD increases with body size when males are the larger sex, and decreases with body size when females are the larger sex. Rensch's rule is well supported...
