Abstract : Investigated the population dynamics of a Microtus duodecimcostatus population by capture-recapture in Southern France during two years. The study was carried out in an apple orchard every three months on an 1 ha area. Numbers varied between 100 and 400 (minimum in summer). Reproduction occurred over the year and was lowest in winter. Renewal of the population occurred mainly in autumn. The population contained erratic individuals which did not take part in the reproduction. Resident individuals had a longer lifespan and home ranges always located at the same place. Mean adult body weight varied only among females in relation to the reproductive rate. The observed demography of M. duodecimcostatus could be explained by biological traits (litter size, longevity) and by features of the habitat (high and constant level of resources, low level of disturbance), suggesting that social behaviours are an important regulating factor of numbers.
