Taxonomic, functional, and phylogenetic diversity of anuran assemblages across habitats and seasons in a Neotropical savanna
Differences between habitats and seasonal changes in climate are some of the main factors responsible for shaping diversity patterns and biological community structures. In this context, anurans are considered excellent models for ecological studies due to their high sensitivity to environmental changes. This study analyzed how differences between open and forested formations and seasonality influence the taxonomic, functional, and phylogenetic diversity of anuran assemblages in an area of Neotropical savanna. Parameters of taxonomic (species richness—SR), functional (functional diversity—SES.FD, functional dispersion—FDis, and functional redundancy—FR), and phylogenetic diversity (phylogenetic species variability—PSV and phylogenetic species richness—PSR) were used to quantify spatiotemporal changes in the anuran assemblages. Sampling was carried out over 15 months, using pitfall traps and active searches. In total, we recorded 598 individuals belonging to 21 species and seven families. Species composition, SR, and PSR differed between habitats and seasons, the latter two being higher in open formations during the rainy season. SES.FD differed seasonally and was higher in the dry season. FDis, FR, and PSV did not differ between treatments. Anurans from forested formations were functionally and phylogenetically clustered during the rainy season, while those from open formations were functionally clustered during the same season. Habitat type and seasonal variation were important in determining the taxonomic, functional, and phylogenetic diversity of the anuran assemblages. However, changes in climate and land use are expected to negatively impact the ecological and evolutionary diversity of these organisms in the Cerrado, reinforcing the importance of conservation policies and actions.

期刊介绍:
Ranked by the ISI index, Biotropica is a highly regarded source of original research on the ecology, conservation and management of all tropical ecosystems, and on the evolution, behavior, and population biology of tropical organisms. Published on behalf of the Association of Tropical Biology and Conservation, the journal''s Special Issues and Special Sections quickly become indispensable references for researchers in the field. Biotropica publishes timely Papers, Reviews, Commentaries, and Insights. Commentaries generate thought-provoking ideas that frequently initiate fruitful debate and discussion, while Reviews provide authoritative and analytical overviews of topics of current conservation or ecological importance. The newly instituted category Insights replaces Short Communications.
