THE CURRENT DISTRIBUTION OF THE STRIPEDFIELD MOUSE ( <i>APODEMUS AGRARIUS</i> PALLAS, 1771) WITHIN THE EASTERN TRANSBAIKALIA: NEW FINDINGS IN THE DISJUNCTION AREA
Materials on the new findings of striped field mouse ( Apodemus agrarius ) within the Transbaikalia are presented. Earlier, the territory in the basins of the rivers Onon and Ingoda was the area of the species range disjunction. Some possible options for the appearance of striped field mouse in this territory are discussed. We consider the delivery of the species from the Argun River basin with a cargo of agricultural products to the lower reaches of the river Onon or the upper reaches of the river Shilka as the most likely event. Currently, striped field mouse is a common species of floodplain shrub in the lower reaches of the rivers Onon and Ingoda.
