摘要

分别于2007年6～10月采集了浙江金华、临安和丽水三个地区的虎纹蛙(Hoplobatrachus rugulosus)共102只进行肥满度研究,以期为我国唯一的国家二级无尾两栖类的保护提供一定的参考依据。本研究结果显示:浙江地区虎纹蛙的肥满度指标K在夏秋季节、雌雄个体以及成幼体之间均没有显著性差异(P>0.05);而重/长指标Kwl在夏秋季节和成幼体之间则存在着极显著的差异(P<0.01),而在性别间的差异性却并不显著(P>0.05)。通过对虎纹蛙样本肥满度指标K和重/长指标Kwl的比较,得知Kwl具有更高的灵敏度,并建议在无尾两栖类的肥满度研究中将两种指标结合使用,以便得到更为详尽的研究结果。

Abstract：

The relative fatness of 102 tiger frog (Hoplobatrachus rugulosus) in Jinhua,Lin'an and Lishui,Zhejiang province was studied from June to October in 2007.The results showed that there were no significant differences in different seasons,sexes or ages in the relative fatness(P>0.05).The indexes of mass/length(Kwl) showed more significant differences between summer and autumn,adult and subadult(P<0.01),but different sexes had no significant difference(P>0.05).Compared with the relative fatness,Kwl was more sensitive than K in statistics,and this suggested that two indexes should be used together in Anuran relative fatness research.The results are useful for the wild Anuran's conservation.

Key words： Zhejiang province tiger frog relative fatness mass/length
