Male mating success in a population of Woodhouse's toad (Bufo woodhousei) with a lek mating system was studied over a period of 5 years. Size-related mating patterns indicated by analysis of male mating success on a seasonal or yearly basis resulted from demographic changes in the size distribution of the population within a season rather than from sexual selection. Multiple regression analyses of three male traits (call rate, male size and number of nights of participation in chorus activity) revealed that only call rate explained a significant amount of variation in male mating success in 2 of 3 years. These results are discussed in the light of previous investigations of sexual selection in anurans that relied on limited observations of breeding activity within a season.
