Figure 1
Prey categories in the diet of Pristimantis paulodutrai from a restinga area in the municipality of Mata de São João, state of Bahia, Brazil. (a) percentage of occurrence of each consumed alimentary category (number of stomachs with an alimentary category averaged for the total number of non-empty stomachs); (b) average percentage of prey categories; (c) average percentage of biomass contribution; and (d) IRI%, index of relative importance (Pinkas 1971). Numbers at the top of columns represent non-transformed values

Hierarchical clustering analysis (Ward's method) on the Index of Relative Importance (IRI %) (Pinkas 1971PINKAS, L., OLIPHANT, M.S., IVERSON, I.L.K. 1971. Food habits of albacore, bluefin tuna and bonito in California waters. Fish Bulletin 152:1-105.) calculated for alimentary categories eaten by Pristimantis paulodutrai in four different habitats of a restinga area in the municipality of Mata de São João, state of Bahia, Brazil. Reserva Sapiranga: habitat 1, forested environments containing springs, streams, and rivers; habitat 2, forested environments without bodies of water on the ground and with less than 20 tank bromeliads in a sample unit of 60 x 25 m. Praia do Forte: habitat 3, sandy soil covered by many shrubs and terrestrial tank bromeliads under direct sunlight (> 100 bromeliads per sample unit); and habitat 4, riparian forest that surrounds a lake formed by the freshwater Timeantube river, the latter filled with emergent vegetation

Table 1
Prey categories in the diet of Pristimantis paulodutrai within four habitats of a restinga landscape in the municipality of Mata de São João, state of Bahia, Brazil. Habitats are ordered following clustering structure resulted from Ward’s method solution (Figure 2). An empty cell indicates a non-available prey category in habitat. Values in parentheses correspond to non-transformed data. Reserva Sapiranga: habitat 1, forested environments containing springs, streams, and rivers; habitat 2, forested environments without bodies of water on the ground and with less than 20 tank bromeliads in a sample unit of 60 x 25 m. Praia do Forte: habitat 3, sandy soil covered by many shrubs and terrestrial tank bromeliads under direct sunlight (> 100 bromeliads per sample unit); and habitat 4, riparian forest that surrounds a lake formed by the freshwater Timeantube river, the latter filled with emergent vegetation.
