Feeding Ecology of Kassina senegalensis in Cameroon (Amphibia, Anura, Hyperoliidae)

抄録

We studied the diet of a population of Senegal running frogs Kassina senegalensis, a ground dwelling hyperoliid. Prey inventories were collected in May by stomach flushing 27 male and 28 female frogs from one population from Bénoué National Park, Cameroon. Sexes did not differ in body size, or size or number of prey items. The most frequently taken prey item was Orthoptera (36%) and Hymenoptera (24%) and Aranae (10%) followed it. The proportion of the 1087 prey samples in the litter did not differ significantly from 625 samples from the frog stomach, indicating a low degree of prey electivity. The data suggest Senegal running frog to be a wide foraging generalist.
