Diet of Rhinella scitula (Anura, Bufonidae) in the Cerrado, Brazil: the importance of seasons and body size
The aims of this study were (1) to analyze the diet of Rhinella scitula in different seasons (dry and rainy), and (2) to examine resource partitioning among sexes and body-size categories. Individuals were collected during active searches along a riverbank in the Serra da Bodoquena National Park, Br...

| description | The aims of this study were (1) to analyze the diet of Rhinella scitula in different seasons (dry and rainy), and
(2) to examine resource partitioning among sexes and body-size categories. Individuals were collected during active
searches along a riverbank in the Serra da Bodoquena National Park, Brazil. Formicidae, followed by Coleoptera and
Isoptera, had the highest importance index values for males, females, and all individuals combined. Diet composition
was similar between males and females. Larger individuals consumed larger prey, although they fed on small prey as
well. Similar-sized individuals had high dietary overlap. Smaller individuals had a diet as broad as larger individuals,
although composed of different items. Formicidae was the most common prey item for animals collected in both the
dry and rainy seasons, but was more important in the rainy season. During the dry season, R. scitula remained closer
to the edge of the water bodies and showed the widest dietary niche, represented by similar importance index values. |
