THE SMALL MAMMAL FAUNA IN AN AGRICULTURAL LANDSCAPE IN SOUTHERN SWEDEN, WITH SPECIAL REFERENCE TO THE WOOD MOUSE APODEMUS-SYLVATICUS

Wood mice and house mice were found in cropped fields, the latter at least during summer and autumn, the former throughout the year. Yellow-necked mice, norwegian rats, field voles, bank voles, water shrews, common shrews, and pygmy shrews were only found in non cropped habitat islands. Wood mice burrow burrow systems and stores are not destroyed by ploughing and wood mice are found in cropped fields throughout winter. However, mice densities, in both autumn and spring, are highest in fields that are currently ploughed (following e.g. direct sowing).
