Abstract

Food resources and population density are key factors influencing spatio-social organisation. We compared the space use of two dormice Glis glis (Linnaeus, 1766) populations differing in density, one high and the other low, in a breeding year 2002 (when trees masted) and in a non-breeding year 2001 (with reproductive failure and a total lack of mast). In the low-density population males always had larger home ranges and travelled longer distances than females. In the high-density population such differences between sexes became significant only in the breeding year. Home ranges and distances travelled each night were larger in the low-density population, but only for males.
