Abstract
In amphibians, theory predicts that male mate choice with respect to female body size can be expected to occur when female fecundity is related to body size and when the time and energy invested into one mating are relatively large. Based on experimental observations, we tested whether male mate choice occurs in a population of the Andrew’s toad (Bufo andrewsi), a species in which both assumptions are likely to be met. When a male B. andrewsi was placed with a gravid female and a non-gravid similar-sized female, the male did not discriminate between them. When two gravid females with distinct size differences were provided to a male, the male preferred the larger one. In an experiment in which two different-sized gravid females were put in two separate transparent cylinders to exclude potential chemical cues, males spent more time in proximity to the larger gravid females and jumped more frequently towards the larger gravid females than the smaller ones. These findings suggest that male B. andrewsi recognizes female body size, exhibits mate choice, and prefers to mate with larger females that provide greater reproductive potential.
