Abstract

SUMMARY - Investigations were carried out in the granite part of the Limousin to study almost twenty thousand pellets of Tyto alba and analyse the distribution of small Mammals found in these pellets. Their study showed the existence of twenty-two small Mammals and emphasized the diversity of the country. Several ecological factors such as the wet and closed or drier and open landscape, the number of days with frost, artificial meadows mainly acted on the distribution of species. Only Microtus subterraneus and Muscardinus avellanarius were in the southwestern limit of their areas of distribution. The gaps in the distribution of Apodemus flavicollis, Arvicola terrestris, Microtus arvalis, Myoxus glis and Neomys anomalus are discussed. The central European group and the southwestern European group of small Mammals contributed to the population of the Limousin.
