Abstract:
:This study examines the idea that variation in forelimb length among male anurans influences reproductive success, and does so independently of body size. Analyses of covariance and multivariate analyses of morphological data for five species of explosives breeders are used to test the prediction that for species in which male-male displacements contribute to variation in male reproductive success, amplectant males have longer forelimbs than do non-amplectant males at any body length. The findings for four of five species are in agreement with expectation. The results lend support to the suggestion that for explosive-breeding anurans, the large-male mating advantage may not be a consequence of large body size per se, but rather is due to the fact that large males have longer forelimbs with which to grasp females securely during amplexus and thus resist displacements by competing males.
