摘      要：Geographic variation of morphology is an important topic of evolutionary biology,and research on geographic variation can provide insights on the formation,evolution,and adaptation of species and *** vertebrate skull is a developmentally and functionally complex morphological structure with multiple functions,that is susceptible to vary according to selection *** this study,geographic variations in skull morphology of Batrachuperus karlschmidti from four different geographic populations(Shade,Gexi,Shangluokema,and Xinduqiao)were examined via geometric *** significant differences were found among these populations with regard to skull size;however,significant variation was found in skull *** most notable shape changes are the relative sizes and positions of the frontal,maxilla,pterygoid,and *** shape changes were not related to ***,due to limitation of sample populations and size,the results of this study need to be further verified by more sample populations and individuals in the *** results of this study contribute to our knowledge about these aspects of morphological variability in this species as well as in hynobiid salamanders.
