Abstract
|
|
|
|
Age variation and secondary sexual dimorphism in four external and 27 cranial characters of 102 specimens of striped firld mice, Apodemus agrarius coreae Thomas, from Cheongju, Korea, were analyzed statistically. Specimens were classified as subadults, young adults, middle-aged adults, and old adults, and variation of morphometric characters among the four age classes was evident. Significant secondary sexual dimorphism among sexes of the same age class was not revealed. Teh specimens of the same age class have to be used in further analyses to clarify geographic variation of morphometric characters in Apodemus agrarius from Korea.
