 en Behavior and Morphologic Adaptive Selection of Sexual Partnership in a Population of Verrucous Digging Frog ( Kaloula verrucosa check for this species in other resources ) from Kunming

Abstract

Forty-eight mated verrucous digging frogs ( Kaloula verrucosa check for this species in other resources ), collected from the suburb of northeast Kunming City, were compared and measured. Meanwhile their mating behavior was observed in the field. Pearson correlation coefficients of snout-vent length (SVL), body weight and head width were bigger than 0.5. Regression analysis of SVL and body weight was made among variables. The results showed that the selection of body length and the mating relationship of individual weight between male and female submitted good linear relation. Female of K. verrucosa often chose the most suitable male whose SVL was (81.8±5.7)% in its SVL and body weight was (53.1±10.7)% in its body weight. Female chose male who had longer SVL and lighter weight, which would help creating a better dimension for mating relationship, including the male skin derivative length and cloaca position between male and female while mating etc. K. verrucosa belonged to the pattern of female selection. Female was attracted by male's calling and positively moved to male. They would mate if the cases of male were suitable for female.
