Some factors influencing the breeding season of Praomys natalensis

C.M. Swanepoel

Abstract


As part of a demographic study of Praomys natalensis in an agricultural area on the Rhodesian highveld, a preliminary investigation was carried out into some of the factors which might be of importance in determining the timing of its breeding season. Information on breeding and nutrition was obtained by both live and snap trapping. Breeding was confined to the late summer months in natural grassland areas but occurred in winter in wheat fields. Availability of nesting sites was adequate at all times. Analysis of stomach contents indicated that the protein content of the diet was adequate for breeding in all seasons. The possible influence of green grass and insects in the diet is discussed.
