The acclimatized ( Ondatra zibethica L.) of Yakutia

Acclimatized in the thirties, the muskrat entered the fauna of Yakutia, repopulating all habitats suitable for the species. Later it was found that the burrowing animal activity adversely affects the state of alas biogeocenoses in the zone of permafrost, disrupting the shoreline and provoking increased thermokarst processes in areas close to water habitats. Reducing the negative impacts through improving of habitat conditions can be achieved by holding biotechnical measures aimed at improving the productivity of rodent populations by creating a favorable habitat type that would simultaneously and significantly slow down the process of destruction and swamping the shorelines and irrigation facilities.
