The Harsh-Furred Rat in Nyasaland

Abstract

An account is given of the distribution and biology of Lophuromys flavopunctatus Thomas in Nyasaland. Comparative study revealed differences between populations in the north and south of Nyasaland. The species was always found in areas which at one time supported broad-leaved evergreen forest, the favored habitat being dense undergrowth (bracken scrub) at the edge of forest. It may be active at all hours but is chiefly nocturnal. Population structure, seasonal fluctuations in numbers, reproductive condition and color change were analyzed for the period March 1962 through May 1963. Breeding took place only during the warm wet season between October and early May; litter size varied between one and 4, three being the most usual. Data on the feeding habits, disease rate and parasites are presented. Lophuromys feeds chiefly upon insects and worms and does not usually excavate tunnels. About 9% of the specimens trapped were diseased, the disease rate being highest during the wet season.
