Abstract

It is generally accepted that high quality males are those that succeed inmale-male competition: in either aggression or rivalry to attract and be selected by females. Previous studies of amphibians have suggested that the main characters influencing male mating success include variation in call characteristics (e.g. call rate, call intensity), calling behaviour, body condition, age and chorus tenure. In the present paper, several of the characters influencing female mate choice (male body size, body condition, call rate, call frequency and chorus tenure) are investigated in two closely related, explosive breeding frog species Litoria chloris and Litoria xanthomera. Smaller males of both species are shown to be more successful than largermales and this success is attributed to the increased chorus tenure of smaller males in L. xanthomera. This increased chorus tenure was attributed tothe lower total energy used per call by a small male calling at a higher frequency. Whether increased chorus tenure explains female mate choice in L.chloris is uncertain but is highly probable given the strong similarity between the two species in both ecology and call characteristics.
