花狭口蛙两性异形及其繁殖习性

Sexual Dimorphism and Multiplication of Kaloula pulchra pulhra Gray

本研究的81只(其中33雄,48雌)花狭口蛙(Kaloula pulchra pulhra Gray)成体标本采自肇庆北岭山地区,对其成体雌雄异形、繁殖行为和生境等进行研究.成年雌雄蛙的体长(t=38.882,df=79,P<0.01)、体重(t=11.299,df=79,P<0.01)、头长(F1,79=3.27,P<0.05)等形态特征差异显著.成年雌雄蛙的头长(F1,79=3.27,P<0.05)、平均耳径(F1,79=1.91,P=0.172)、吻长(F1,79=0.02,P=0.878)、眼间距(F1,79=0.003,P=0.957)等其他局部特征与体长皆呈正相关.花狭口蛙的繁殖策略为r-对策.

This study took 81 adult specimens（33 male and 48 female） of Kaloula pulchra pulhra Gray,col-lected from Zhaoqing Beiling Hill,and the adult sexual dimorphism,reproductive behavior,habitat were studied Adult male and female frogs’ body length（t=38.882,df=79,P0.01）,weight（t=11.299,df=79,P0.01）,head length F1,79=3.27,P0.05） and other morphological characteristics were significantly different.Head length of adult male and female frog（F1,79=3.27,P0.05）,the average ear diameter（F1,79=1.91,P=0.172）,snout length（F179=0.02,P=0.878）,eye space（F1,79=0.003,P=0.957）,and other local features and factors exhibited a positive correlation of body length.Breeding strategy of K.pulchra pulhra was rcountermeasures.
