Heavily male-biased operational sex ratio and high male density characterizing explosively breeding anurans are expected to enhance the opportunity for sexual selection through large-male mating advantage brought about by severe male–male competition. However, our previous study on the temperate frog Rana chensinensis suggested that these two factors might restrict the opportunity under natural conditions...
Knowledge of how mating success is related to body size may provide insight into the evolution of social systems. This study investigated the mating system and relevant social behavior of a temperate anuran (Rana chensinensis) at three localities in northern China. During chorusing, males aggregated and persisted in the communal spawning ponds with a density of 10–26 frogs per m2 water area and operational...
