HERNANDEZ CORDOBA, Oscar Darío. Food Habits for a Population of Eleutherodactylus johnstonei in an Area on the Bank of River Melendez, South of Cali, Valle del Cauca. rev. cienc. [online]. 2014, vol.18, n.2, pp.153-160. ISSN 0121-1935.

Due to the ecological importance of knowing the variation in the diet of a species along its geographic range, the objective of this work was to establish the diet of Eleutherodactylus jhonstonei in a population located at south in the city of Cali. A total of 43 individuals were captured, and the food preferences and niche breadth were calculated by stomach content analysis. Finally, diet structure was compared between sexes and showed significant differences (p=0,017). Additionally, It was found that E. jhonstonei is a generalist species (Niche breadth=0,6) whose diet depends on the abundance of prey in the environment withouth showing a food preference, this is a reason why the species has become a successful colonizer

Keywords : food preference; diet; niche breadth; stomach content; trophic ecology.
