The studies were conducted in the laboratory of Mammalogy, Herpetology and Paleozoology of the Institute of Zoology of the Academy of Sciences of Moldova. The influence of the climatic conditions on the M. spicilegus species population was studied from 2008 to 2012 during spring, summer and autumn periods in agricultural ecosystems and fallow grounds from the central part of Moldova. The abundance of the species in the years with favorable climatic conditions was higher, while in 2010 and 2012 with unfavorable climatic conditions in summer, the number was significantly lower compared with the same period in the previous years, varying from 6.4% to 15.9%, and the ecological significance decreased to 3.69 - 4.2, the species becoming subdominant in its specific habitats. In autumn, the population restores its number and the species abundance reaches about 58.5%, the ecological significance index being 23.9. The mound building mouse is a characteristic or permanent species in agrocenoses. Unstable weather in late winter - early spring negatively affects the population of M. spicilegus, increasing individual mortality up to 35-67%.
