The ecological behaviour of one Apodemus spp. population in the area of Villiago, Triva, Pasa (Belluno, Italy).

Aims: In this research the ecological behavior of a population of Apodemus spp. living in the East North of Italy (Veneto, Italy) is analyzed. In this specific instance, we tried to evalutate the activity of the animals as regards meteorological variabilities and the exact hour of capture of three congenerouses Apodemus agrarius (Pallas, 1771), Apodemus flavicollis (Melchior, 1834) and Apodemus sylvaticus (Linneus, 1758), with special reference to the component given by the wild Striped Field Mouse, in a purely agricultural area, situated in the commune of Sedico (Belluno, Veneto) and inserted in the phytoclimatic Esalpico district. Following the preliminary study which was intended to define the check-list of the microteriofauna living in the area of study in connection to the present environmental typologies, it has been decided to examine in the period March - December 2004 the fauna component given by the three kinds of Apodemus spp. in defined a sub-area of 1 ha surface, composed by particles with different soil and various vegetation coverage where the three species are coexistent.
