dc.description.abstractClimate conditions that favored vegetation growth made up an important prerequisite for the increase of M. arvalis population density from 2-4 colonies per hectare in April on the lucerne fields in the Center region up to 80 colonies per hectare in September and even 200 – in October. The highest levels in agrocenoses have been registered in July and October – 23% and 29,6% respectively. The index of anthropic adaptation (Ii) of the studied species of small mammals has also been determined. The highest values of this parameter have been recorded in M. arvalis (14.3) and M. rossiaemeridionalis (12,5). This is explained by the adaptive peculiarities, their individuals being primary consumers of vegetable food (lucerne, clover, etc.). The equation of multiple linear regression was developed and it reflects the correlation between the number of M. arvalis individuals expressed in colonies per hectare and the monthly Martonne aridity index D=-15.67 + 2,88*Ia, that allows the forecast of the number of microtine species.en
