| description | The diet of Lithobates zweifeli was studied by means of stomach flushing in a seasonal river of Morelos, Mexico. Diet was analyzed by season (wet and dry), development stages and by sex. Food items were classified by their habits in terrestrial or aquatic prey, and determined to order, family, genus and sometimes to species. The diet of L. zweifeli comprised 102 nutritional components, mainly land habits insects. Hemiptera (Cicadellidae), Lepidoptera (Noctuidae) and Megaloptera (Corydalus texanus) had the highest values of ingestion and frecuence in the diet. We found 54 nutritional components in the dry season, and 84 in the rainy season. The estimated amplitude of trophic niche by the Levin’s method revealed low values in both seasons. Diet was constituted by 63 nutritional components in females, 55 in males and 49 in juveniles. A Chi-squared test showed not significant differences in the diet by development stage, sex, and season. The overlap of the trophic niches estimated by the MacArthur and Levin index revealed low value in sex and season combinations. The floating and riparian vegetation as insects´ habit is important for the feeding of L. zweifeli. |

The floating and riparian vegetation as insects´ habit is important for the feeding of L. zweifeli. Por medio de lavado estomacal de 81 organismos se estudió la dieta de Lithobates zweifeli en un río estacional de Morelos, México. Los datos fueron analizados por épocas del año (lluvias y sequía), estadios de desarrollo y por sexos. Las presas fueron clasificadas por sus hábitos en terrestres o acuáticas, determinadas a nivel de orden, familia y género y algunas veces a especie. La dieta de L. zweifeli estuvo constituida por 102 componentes alimentarios, principalmente insectos de hábitos terrestres. Hemiptera (Cicadellidae), Lepidoptera (Noctuidae) y Megaloptera (Corydalus texanus) tuvieron los valores mas altos de ingestión y frecuencia en la dieta. Se encontraron 54 componentes alimentarios en la época de estiaje y 84 en la de lluvias. La amplitud del nicho trófico estimado a partir del método de Levin reveló valores bajos en ambas épocas del año. El alimento de las hembras estuvo constituido por 63 componentes, el de los machos por 55 y el de los juveniles por 49. Una prueba de Jicuadrada reveló que no existen diferencias significativas entre las dietas por estadio de desarrollo, sexos y épocas del año. El traslape de los nichos tróficos, estimado a partir del índice de MacArthur y Levin reveló valores bajos en todas las combinaciones por sexos y épocas del año. La vegetación flotante y riparia como hábitat de los insectos es importante para la alimentación de L. zweifeli.
