Geographic Variation Of Morphological Characteristics Of Rana Dybowskii And Rana Chensinensis

In this study,the morphological geographical variation of Rana dybowskii and R.chensinensis were studied by measuring the morphology and data analysis.It provided the basis for the study of the classification of R.dybowskii and R.chensinensis.The comparison of the female reproduction of the different geographical populations of R.dybowskii and R.chensinensis,it can be helpful for us to understand the reproduction of evolutionary significance of reproductive variation of different populations of R.dybowskii and R.chensinensis.The main contents of this study are as follows that the differences of male and female sexual size dimorphism and morphological indexes of R.dybowskii in different geographical populations,the differences of male and female sexual size dimorphism(SSD)and R.chensinensis in different geographical populations,and the comparision of difference of female fertility of R.dybowskii and R.chensinensis in different geographical populations.1.The largest SSD of R.dybowskii is Shangzhi population,and the SSD in Ji'an and Baishan population is close.The SSD of Yichun population is smallest and violates the Rensch's rule.R.dybowskii morphological characteristics of female performance for the Yichun population smaller than Shangzhi Baishan Ji'an population,Shangzhi population smaller than Ji'an Shangzhi Baishan and Yichun population in male,except Yichun population,in violation of Bergmann's law.The morphological characteristics of Yichun population were significantly different from those of the other three populations,and the females were significantly smaller than those of other populations,while the males were significantly larger than those of other populations.There were also sectional morphological and heterosexual geographical variations in different populations of the R.dybowskii.2.The SSD of Zhalantun population are bigger than Zhengzhou population,violate the Rensch's rule as well.The sizes of the two regions of the R.chensinensis are different that Zhalantun population are greater than the Zhengzhou population.It followed Bergman's law.There were also sectional morphological and heterosexualgeographical variations in different populations of the R.chensinensis.3.In addition to the Zhengzhou population of R.chensinensis,the female body weight and body length of the two species were positively correlated with the fecundity and there is geographic variation in reproductive output.
