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. © 2011 by The Herpetological Society of Japan.

Fire is a frequent feature of African grasslands because agriculture is often used as a management tool in conservation areas. Richness, diversity, and abundance of amphibians were compared in four areas of montane grassland subjected to different fire regimes in Nyika National Park (Malawi, southeastern Africa). The surveys were performed using drift fences and pitfall traps randomly set in four areas (12 sites) subjected to the following fire regimes: (A) no fire for at least 15 years; (B) no fire for at least 10 years; (C) no fire for at least 6 years; and (D) annually burned. We also measured the vegetation cover and vegetation height. We collected 370 amphibians from 17 species and six families during 50 days sampling period. The lowest value of abundance was found in areas C and D. The amphibian species Hyperolius marmoratus and H. nasutus were most abundant in the control area A. Arthroleptis xenodactyloides, Amietophrynus gutturalis and Am. maculatus were found in all areas. There was a strong correlation between vegetation height and species richness. Vegetation structure, which is affected by fire, appears to be a key factor impacting amphibian assemblages in montane grasslands. © 2013 by The Herpetological Society of Japan.
