长白山中国林蛙肥满度及体尺指标分析

Analysis of the Relative Fatness and Its Body Ruler Index of Rana chensinensis in Changbai Mountain

对长白山中国林蛙的肥满度及体尺指标状况进行了调查分析,结果表明:长白山中国林蛙肥满度的变化范围为6.68～11.83,不同大小、性别的个体肥满度有一定差别,其总体变化规律为幼蛙>雄性成蛙>雌性成蛙.体质量与体长比随体长的增长而增大,最小(体长1.8 cm)0.28 g/cm,最大(体长8.0 cm)5.06 g/cm;雌蛙的体质量水平总体上小于雄蛙,但仅在较小成蛙样本间表现为差异显著.体质量与体长的增长呈幂函数相关,幼蛙、雌性成蛙和雄性成蛙分别具有不同b值(幂指数),其中幼蛙和雄性b<3,雌性成蛙b>3.

The relative fatness and its body ruler index of Rana chensinensis in Changbai Mountain was investigated.The results showed that the range of the relative fatness is from 6.68 to 11.83.The relative fatness has certain difference in sex and larvae and adults,which the general change law is of the larvaethe male adultsthe female adults.The body weight and length ratio increased while the body length grew,from the minimum（body length 1.8 cm） of 0.28 g/cm to the maximum（body length 8.0 cm） of 5.06 g/cm.The body weight level of the female adults is less than that of the male ones generally,but the significant difference is only showed among the samples of the smaller adults.The body weight and length growth present a power function correlation,in which the values of b are different for the larvae and the female and the male adults.For the larvae and the male adults,it is b3,while for the female adults,it is b3.
