Long-term dynamics analysis of small mammals in the Republic of Mordovia is given in this paper. Ecological studies on the small mammals at Republic of Mordovia were made during the years 2006-2019.There are altogether 17 species. Among the 23,780 captures. A 3-4-year cycle in population fluctuations was revealed for the conditions of this region. It is shown that in unfavorable years under the conditions of temperature and humidity (2010 and 2012), small mammals recovered their population numbers by the end of the growing season due to the existing areas of settlement and concentration centers. The sex ratio of most species over the research average period is almost always biased in the direction of males.
