Rodent communities and a population of A. agrarius (Pallas, 1971), subjected to different degrees of urbanization were studied. A park in the center of a city, a suburban tree stand and woods outside the suburbs were selected sites. Differences in the composition and variety of the rodent community and in the structure and population processes of the field mouse, were: age structure, sex structure, weight of adult individuals, maturation rate of females, length of the reproduction season and survival of the population during winter. The different pressure of the rodent community (which becomes increasingly impoverished along the urbanization gradient) and environmental factors specific to urban areas are discussed as reasons for the changes in the field mouse population.
