East European vole (Microtus rossiaemeridionalis) in Surgut

In 2013, East European vole was registered in the city of Surgut. This paper is aimed at assessing the current state of East European vole population inhabiting the northern border of the West Siberian area. In 2002-2015, the researchers studied the population of these small mammals in Surgut and registered about 3,000 voles belonging to 17 species, including 81 cpecimen sampled for study. We used trapping grooves, fences made of polyethylene film and trap lines to catch the voles, later subjected to the standard examination. during the examination the researchers measured the length and weight of each animal, identified its sex, age, reproductive state, evaluated the relative abundance of animals, and brushed each animal in search for ectoparasites. After studying the spatial distribution of East European voles in Surgut, we came to the conclusion that they are more often found in the gardens and in the country (compared to habitats of the undeveloped city territory)...
