摘要
测定五种分布于浙江的蝰科蛇类的体长和尾长,检测尾长的两性异形和种间差异。五种蝰科蛇的两性个体尾长均与体长呈显著的正相关,五种蝰科蛇间体长差异显著。协方差分析显示雄性的尾长显著大于雌性。除烙铁头、竹叶青之间其余相对尾长的差异显著。
We tested the sexual dimorphism and interspecific differentiation of tail length by measuring the snout-vent length and tail length in five adders (Viperidae) which distributed in Zhejiang Province. The tail length of both sexes was positively correlated with the snout-vent length in five adders (Viperidae) apparently. The interspecific differentiations of the snout-vent length between five adders (Viperidae) are significant. The ANCOVA showed that the tail length of adult females was significantly shorter than adult males'. The interspecific differentiations of relative tail length of each kind of adders were significant except Trimeresurus mucrosquamatus and Trimeresurus stejnegeri.
