| Sumario: | Melanophryniscus species from the Selva Paranaense exhibit explosive reproductive strategies and larger males might have greater reproductive success in direct competition for females. The goal of this contribution was to analyze whether there is a difference in body size between males captured amplexing and non-amplexing, in the three Melanophryniscus species (M. atroluteus, M. devincenzii and M. Krauczukii) of Paranaense Forest (27°29'25.00 ‘S, 55°40'7.30 ’W), Misiones, Argentina. For this, the following body traits were considered: snout-vent length, arm length and body mass. The differences were evaluated using Type III General Linear Models. In general, males in amplexus showed equal or lower mean values for the three body traits compared to non-amplexing males. Our findings suggest that body size is not under selective pressure and may not play a significant role in mating success in the studied population. |
