多疣狭口蛙昆明种群雌雄配对行为及形态适应选择

测量和比较采自昆明东北郊的24对抱对多疣狭口蛙(kaloula verrucosa)标本,同时野外观察其繁殖行为.配对雌雄蛙的体长、体重和头宽3个形态特征的Pearson相关系数大于0.5;择体长和体重作回归分析,结果表明,雌雄蛙体长选择和雌雄蛙体重配对都呈良好的线性关系.雌蛙选择雄蛙体长为自身体长的(81.8±5.7)%、体重为自身体重的(53.1±10.7)%的个体为最适配偶.雌蛙选择体长较长而体重较轻的雄蛙作为配偶,这样有利于形成较好的空间(雄性胸腹部皮肤腺长度,雌雄抱对时泄殖孔位置等)配对关系.多疣狭口蛙属于雌性选择模式,即雄蛙鸣叫,雌蛙受吸引,主动接近雄蛙,如果雄蛙条件适合则形成配对.
Behavior and Morphologic Adaptive Selection of Sexual Partnership in a Population of Verrucous Digging Frog ( Kaloula verrucosa ) from Kunming
Forty-eight mated verrucous digging frogs (Kaloula verrucosa), 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.
