Cape genet Genetta tigrina diet in the Albany Thicket Biome, South Africa

Abstract

The diet of the Cape genet Genetta tigrina is only well known in the coastal forests of South Africa, where either arthropods or small  mammals are their dominant prey. Here, we aimed to demonstrate this species’ opportunistic behaviour by investigating its feeding  habits in the Albany Thicket Biome (Great Fish River Nature Reserve, Eastern Cape). We analysed 61 scats collected across the four  seasons of the year deposited at 15 latrines by Cape genets, as confirmed through video-recordings. Small mammals were primary and  arthropods secondary prey, respectively. We recorded seasonal variations in both percentage occurrence and volume of food remains, with peaks in consumption of small mammals in winter, and arthropods in spring–summer. The consumption of supplementary food  items such as plant material was higher in spring and autumn, and particularly seeds/fruit in autumn. Reptiles and other food items  occurred as trace foods throughout the year, although birds reached a peak in winter. Intermediate to high diet diversity and low to  intermediate diet breadth indices were obtained for all seasons. Inter-seasonal diet overlap was intermediate to high depending on the  diet descriptor and pairs of seasons considered. Cape genet is therefore a generalist opportunist forager that likely adjusts its diet  according to seasonal variations in main prey availability, potentially leading to apparent seasonal or local “specialisms”.
