Field capture of small mammals in the northeast of Lesser Khingan and the Bureinsky range

The paper considers the results of expedition captures in Lesser Khingan and the Bureinsky range, for the period of 2010-2018. They have resulted in finding of eleven species of rodents. The representatives of the genera Apodemus (A. peninsulae), Myodes (M. rutilus), Craceomys (C. rufocanus), and Tamius (T. sibiricus) are widespread from the southern to the northern points of the territory. The Apodemus agrarius and two species of the East Asian voles (Alexandromys fortis and A. maximowiszii) are spread in the southern part of the Khingan-Bureya Highland. The northern boundary of the A. agrarius habitat stretches from the north of Lesser Khingan to the south of the Bureinsky Range. This boundary coincides with the northern edge of the A. fortis habitat. The A. maximowiszii moved the much further to the north along the Bureinsky range. Single specimen of the Mus musculus, Micromis minutes and Rattus norvegicus species occur in natural biotopes. The Alexandromys evoronensis was locally found in the north of the area.
