Food rate of Ptychadena mascareniensis, P. pumilio and Hoplobatrachus occipitalis, three Anura of degraded areas of Banco National Park, Côte d’Ivoire

Abstract

Food rhythms of Ptychadena mascareniensis, P. pumilio and Hoplobatrachus occipitalis were studied in Banco National Park (Cote d'Ivoire) during the dry and rainy seasons. The food intake of the species of Ptychadena genus takes place in the morning from 6h to 12h and in the evening between 18h and 24h with peaks located at 12h and 24 h respectively. Hoplobatrachus occipitalis feeds on 3h to 9h and from 15h to 21h with peaks located at 9h and 21h. Most of the food bolus in both species of Ptychadena genus corresponding to the peaks is composed of Insects. Hoplobatrachus occipitalis is mainly feeds on amphibians at 9h and molluscs at 21h.
