Tactical dimorphism : the interplay between body shape and mating behaviour in the swordtail Xiphophorus multilineatus (Cyprinodontiformes: Poeciliidae)
Alternative reproductive tactics (ARTs) are characterized by dimorphism for reproductive phenotypes (i.e. tactical dimorphism). Tactical dimorphism often evolves as a response to differing phenotypic optima for a shared reproductive trait between members of the same sex in a species. We characterized dimorphism for body shape between ARTs in the swordtail fish Xiphophorus multilineatus and investi
