Diet, activity patterns, microhabitat use and defensive strategies of Rhinella hoogmoedi Caramaschi & Pombal, 2006 from a humid forest in northeast Brazil
We studied the natural history of the leaf-litter toad, Rhinella hoogmoedi Caramaschi & Pombal, 2006, in a rain forest located in an altitudinal rocky remain within the Brazilian caatinga biome. Rhinella hoogmoedi was more abundant during the first half of the wet season, when recruitment of new cohorts was observed. Leaf litter was the most commonly used substrate and activity was mainly diurnal. There was a positive relation between maximum prey size (length/volume) and predator size; ants and mites were the predominant prey in adults and froglets, respectively. The following defensive strategies were registered: cryptic and polymorphic colour pattern, immobility, thanatosis, generation of distress calls and production of a foamy substance by the paratoid glands. The similarities in natural history aspects among members of the R. margaritifera species group indicate a case of ecological niche conservatism.

- The Herpetological Journal is an international scientific journal that publishes papers on the natural history of amphibians and reptiles. Experimental, observational and theoretical studies are published along with reviews and book reviews. Faunistic lists, letters and results of general surveys are not published unless they shed light on herpetological problems of wider significance.
