Anuran Assemblage Structure in the Serra Da Capivara National Park, Piauí State, North‐Eastern Brazil

Research on the anuran assemblage of Serra da Capivara National Park, Brazil, reveals that while these species do not exhibit spatial or trophic niche partitioning, their habitat preferences are strongly influenced by phylogenetic history. The study analyzed microhabitat use and diet data from 551 individuals across 16 species, employing null models to assess niche dimensions. Findings suggest that spatial patterns in resource use are constrained by evolutionary factors, whereas dietary patterns reflect local ecological adaptability. This dual influence highlights the complex organization of anuran communities in semiarid environments, offering insights into species coexistence mechanisms.
