The diet of the wood mouse (Apodemus sylvaticus) was investigated over an annual cycle in three biotopes of Kabylie of Djurdjura, differing in the structure of the vegetation and the anthropic action (oak forest, maquis and cultivated zone). The analysis of 140 stomach contents was restricted to three main components: seeds, vegetative parts of plants and arthropod remains, expressed in dry weight and percentages of occurrence. Five independent variables were considered: habitat, sex, sexual activity, season and age. In the three biotopes wood mouse was primarily granivorous, seeds occurring in 99.3% of the stomachs, for 91.5% of dry weight; seasonal variations were significant, with higher occurrence of seeds in winter and summer. Vegetative items (leaves, stems and flowers) were overall rather frequent (occurrence: 19.3%; dry weight: 4.0%), mainly in winter and spring, in the cultivated zone. Arthropods, mainly insects, were frequently preyed by adults (occurrence: 26.4%; dry weight: 4,4%), particularly in the forest. This diet from Mediterranean habitats is discussed by comparing it with previous data in the same biome and in the northern part of the range.
Since the publication of “The Atlas of European Mammals” in 1999 plenty of new data have been collected on the distribution of Apodemus spp. in Lithuania. These data have changed our knowledge of the comparative distribution of ?A. sylvaticus and A. uralensis in the country. Essentially, A. uralensis is widespread in the north-western part of the country, whereas A. sylvaticus is found only in southern and eastern Lithuania. Both species reach the limits of their geographical ranges in Lithuania.
