The role of traditional nomadic pastoralism in the spatial and genetic subdivision of the distribution of populations of small mammals in mountain areas and their sanitary and epidemiological significance (on the example of Tuva)

Abstract

The data on the genetic and spatial subdivision of populations of synanthropic species of small mammals, their dependence on the intensity with the territories of distant-pasture cattle tending are presented, and some patterns of indicators of ectoparasite infestation of their communities are revealed. The factor determining the genetic and spatial differentiation of populations of small mammals can be attributed to the relationship of small mammals with ungulates that has long historical roots (Neogene, Anthropogen). At present, these relations have been preserved with domestic ungulates, which, along with physical and geographical ones, determine the genetic and biotopic differentiation of populations of small mammals. The assumption is made about the deep historical roots of the establishment of such relationships by pasture ungulate animals from the neogene and pleistocene.
