Abstract

, 1979: Synurbization processes in a population of Apodemus agrarius. II. Habitats of the striped field mouse in town. Acta theriol., 24, 30: 405-415 [With 2 Tables & 5 Figs.] Trapping of Apodemus agrarius (Pallas, 1771) was carried out in 78 urban green areas of Warsaw during the period from 1976-1978. It as known that the species is not only the commonest, but also the most widely spread in town, of all the urban rodent community, occurring in 55% of the study areas. By means of a 0-10 point scale, proposed here, all the areas were classified in respect of 5 criteria: size of area, size of complex in which the area is included, distance from town boundaries , shelters and »quietness«. It was found that the most important factor for A. agrarius in urban green areas is a sufficient amount of shelters; and the »distance« is the least important one, since the rodents also occur in the city district. The habitat requirements of A. agrarius in town are discussed. [Res. Inst. Environ. Develop., Krzywickiego 9, 02-078 Warszawa, Poland].
