The modern fauna of semi-aquatic rodents of Central Yakutia was formed in the middle of the 20th century. after the acclimatization of the muskrat (Ondatra zibethica L.) on the territory of the Yakut Autonomous Soviet Socialist Republic (1939-1956). The native species are the water vole (Arvicola terrestris L.) and the root vole (Microtus oeconomus Pallas).
Human intervention to enrich the commercial fauna contributed to the formation of new interspecific relationships. All of the above species live and feed mainly in water bodies and adjacent biotopes.
It is known that invasive species, coming into contact with populations of native species, significantly transform the structure of biogeocenoses, and their appearance has ecological, economic significance, and sometimes social consequences.
The article presents the ecology of semi-aquatic rodents of the Central Yakut Lowland, as a genus competing for resources and ecological niches, the limitation of which is a direct factor limiting the dynamics of their populations.
A comprehensive analysis of the existing biocenotic relationships that arose in the process of food and spatial relationships among the group of rodents under consideration in the form of competition, in floodplain and taiga-alas ecosystems. Impact of the introduced species on the native fauna in aquatic and semi-aquatic biocenoses of Central Yakutia. Allows you to use specific examples to assess the state and stability of populations of these species.
