The large-male advantage in brown antechinuses: female choice, male dominance, and delayed male death
Male-biased dimorphism in body size is usually attributed to sexual selection acting on males, through either male competition or female choice. Brown antechinuses (Antechinus stuartii) are sexually dimorphic in size, and heavier males are known to sire more offspring in the wild. We investigated four possible mechanisms that might explain this large-male reproductive advantage. We tested if there is a female preference for large males, a female preference for dominant males, if larger males...[Show more]
