Niche overlap and resource partitioning among five sympatric bufonids (Anura, Bufonidae) from northeastern Argentina. The niche overlap and resource partitioning were analyzed for five sympatric bufonids from Northeastern Argenti- na: Rhinella schneideri, R. bergi, R. fernandezae, R. granulosa, and Melanophryniscus cupreuscapularis. The primary objectives were to analyze the diet and pattern of coexistence relative to the microhabitats among species. The bufonids, which are primarily terrestrial, exhibited a preference for small, hard prey such as formicids or coleopterans. The smallest species preferably consumed ants, while R. schneideri preferred beetles. Significant differences were detected for the diets of these five species. In addition, significant overlap in the trophic niche was noted for all species except between R. granulosa and R. schneideri. Studying the diet behaviors and trophic parameters of sympatric species provides important data for understanding the community and for the development of conservation guidelines.read more

Helminth communities in the burrowing toad, Rhinella fernandezae, from Northeastern Argentina
TL;DR: The main goals of this study were to determine the richness and diversity of helminth parasites of Rhinella fernandezae at the component and infracommunity levels and determine the ecological implications of different biotic and abiotic factors.

TL;DR: This study performs a global-scale literature analysis to build up a database of interactions between anuran communities and their preys, from a wide range of geographical areas, using a network approach and finds that anuran–prey networks are not nested, exhibit low complementary specialization and modularity and high connectance when compared to other types of networks.

TL;DR: The results indicate similarities in the diet composition and foraging behavior of P. lisei and P. gracilis, which have similar trophic niche breadth and a high diet overlap.

Dietary Asymmetry in Leaf Litter Frogs and Lizards in a Transitional Northern Amazonian Rain Forest
TL;DR: Frogs may have evolved relatively larger gut storage capacity to offset extended food shortages associated with prolonged inactivity during drought, and differences in consumption of ants by frogs and lizards may relate to differences in defense strategies between the two groups.

Prey selectivity and size-specific diet changes in bufo cognatus and b. woodhousii during early postmetamorphic ontogeny
TL;DR: Graves et al. as mentioned in this paper quantified ontogenetic differences in the diets of toads over a range of sizes that occur within the first month after metamorphosis, and compared prey consumption to prey availability for several prey types consumed by juvenile toads during early ontogeny.

TL;DR: The results of morphological, cinematographic, and muscle stimulation studies reveal that Rhinophrynus has a mechanism of tongue protrusion basically distinct from that of other frogs that project their tongues by means of a lingual flip.

TL;DR: Niche complementarity was observed between these species; although they exhibit high overlap in food, they tended to have low overlap in microhabitat use.
