Contribution to the Knowledge of M1Crotus Guentheri Hartingi from Thebes, Greece
A study was made on the individual variation in a series of Microtus gnentheri hartingi collected near Thebes, Greece during the winter of 1960 to 1961. On the basis of body and cranial measurements no statistically significant differences can be observed between males and females. The mean values and the limits of variation of the body and skull dimensions of the Greek subspecies are compared to those of subspecies of Asia Minor literature and on the basis of them M. g. hartingi is one of the smaller subspecies.An outbreak of the gunther's vole was taking place in Thebes during the present study, and it was easy to observe the specimens during the day. The ratio of the two sexes was 1.69: 1 females more than males. Approximately one fifth of the females were pregnant and the average number of embryos was 5.6 with a range of variation from four to eight.The structure of the upper and lower molar teeth, the variation of the third upper molar tooth, and the construction of the burrow systems are given. © 1965, Walter de Gruyter.
