CASTRO-FRANCO, Rubén; BUSTOS-ZAGAL, María Guadalupe  and  TRUJILLO-JIMENEZ, Patricia. Diet composition of Sceloporus horridus horridus (Sauria: Phrynosomatidae) in tropical deciduous forest, Mexico. Acta Zool. Mex [online]. 2017, vol.33, n.3, pp.443-449. ISSN 2448-8445.

The diet composition of a population of the lizard Sceloporus horridus horridus in the wet and dry seasons was studied in central Morelos, Mexico. Analysis of diversity, variation between seasons, and dietary overlap between males and females were performed. The data were compared with other populations of Jalisco and Puebla, Mexico. The diet included 18 groups of insects; among the most important were coleopterans (69.3%), hemipterans (68.0%), formicids (38.7%) and larvae (37.3%). There were significant differences in the frequency of occurrence and percentage of food intake between wet and dry seasons. Dietary diversity differed significantly between females (H′ = 2.14) and males (H′ = 2.08) as did food intake. Generally, the diet of the studied population is similar to that observed in other populations of this species.
