GARCIA R, JUAN CARLOS; LUCAS-VELASQUEZ, LEONARDO; CARDENAS HENAO, HEIBER  and  POSSO GOMEZ, CARMEN ELISA. Feeding Ecology of the Endemic Rain Frog Pristimantis jubatus (Craugastoridae) in Munchique National Park, Colombia. Acta biol.Colomb. [online]. 2012, vol.17, n.2, pp.411-420. ISSN 0120-548X.

We studied the diet of the rain frog Pristimantis jubatus based on stomach and intestinal contents of 29 individuals from three different localities at Munchique National Park, Colombia. The diet was composed exclusively of arthropods, comprising a total of 66 prey which were in 32 taxa. The most frequent dietary items were Diptera and Hymenoptera, 19.7 % and 16.7 % respectively, followed by Araneae (15.1 %) and Coleoptera (12.1 %). Plant consumption was considered incidental because of its low frequency. This species showed no preference for any type of prey, with a high value of niche breadth (0.68) indicating a generalist diet. Adults and juveniles occupy different perch height. Habitat use and the variety of items found show P. jubatus as a species that can consume any kind of arthropod available in the strata of the forest where it is foraging.

Keywords : Colombia; diet; Munchique National Park; niche breadth; Pristimantis jubatus.
