Nl. Avenant et Jaj. Nel, PREY USE BY 4 SYNTOPIC CARNIVORES IN A STRANDVELD ECOSYSTEM, South African Journal of Wildlife Research, 27(3-4), 1997, pp. 86-93
The diet of four syntopic carnivore species (caracal Felis caracal, wa
ter mongoose Atilax paludinosus, small grey mongoose Galerella pulveru
lenta, and yellow mongoose Cynictis penicillata) over a 12-month perio
d in a coastal shrub ecosystem was examined using seat analysis. Use o
f prey by all four species fluctuated synchronously and tracked corres
ponding fluctuations in prey availability. This, as well as the use of
relatively small food items (e.g. beetles, scorpions and spiders), in
dicate an absence of dietary specialization and an opportunistic feedi
ng behaviour in the carnivores studied, Food niche breadth in all four
species changed seasonally, being widest during spring and contractin
g gradually towards winter. A considerable degree of food niche overla
p existed between species. Rodents (mainly Rhabdomys pumilio and Otomy
s unisulcatus) were the main prey items of all four carnivore species
and were used heavily throughout the year, despite marked declines in
numbers towards winter.
