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

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.
