Parasitic Arthropods of Small Mammals in the Subpolar Urals (Eastern Macro-Slope)

Abstract

Surveys of small mammals (insectivorous and rodents) and their ectoparasites were carried out in the Subpolar Urals (eastern macro-slope) near Mount Neroyka (Berezovsky district, Khanty-Mansi Autonomous Okrug Ugra) in different altitude zones (from 407 to 1018 m above sea level) in 2020 and 2021. A total of 15 species of parasitic gamasid mites, 1 species of ixodid ticks, 11 species of fleas and 1 species of lice were identified. Two counting methods, ditch with pitfalls and trap-lines, were used to better reveal the composition of small mammals (feeders of ectoparasites). Specific parasites of Eurasian water voles, Laelaps muris and Hyperlaelaps amphibius, dominated among gamasid mites regardless of the method of trapping insectivores and rodents. At the same time, the proportion of the Eurasian water vole in the small mammal community of the Subpolar Urals (eastern macro-slope) did not exceed 7%. The group of dominant species also included Laelaps algericus, which was recorded in only three species (of 16 small mammal species recorded in the Subpolar Urals): the Eurasian water vole, the field vole and the Middendorff's vole. Among rare species of gamasid mites, Haemogamasus dauricus is of particular interest, a species not previously recorded in the Urals and Western Siberia. Ixodes persulcatus is a single occurrence in the area. The find of this tick is one of the most northerly in the Asian part of the Russian Federation. Among representatives of flea and lice groups the share of specific species (shrews and red-backed voles) is high. This is probably due to the high mobility of shrews, their close contact with rodents, and the specificity of animal counting methods.
