Evaluation of the “Bottleneck” Effect in an Isolated Population of Microtus hartingi (Rodentia, Arvicolinae) from the Eastern Rhodopes (Bulgaria) by …

2022

An integrative analysis of an isolated population of Harting’s vole (Microtus hartingi) from the Eastern Rhodope Mountains (Bulgaria) was carried out by morphological and morphometric methods, computed tomography, Cytb variation data, and experimental hybridization. Substantial changes in the development of the skull and teeth were found. Nevertheless, those voles can live to the senex stage. A phylogenetic reconstruction based on Cytb sequences showed that M. hartingi from the Eastern Rhodopes forms a separate clade, which is a sister clade to the voles from Northeastern Greece (also from the foothills of the Rhodopes). M. hartingi from the Rhodopes is mostly isolated reproductively …
