SUMMARY:

The study investigates the variation in biodiversity dimension patterns in ant-following birds along the latitudinal gradient in the Neotropical region, a complex theme given the recognized greater biodiversity in low-latitude regions. The research challenges the conventional notion that species richness is synonymous with biodiversity, arguing that other dimensions, such as functional and phylogenetic, are crucial for a holistic understanding and for effective conservation. To understand this multidimensional variation, taxonomic and functional data from the assemblies of ant-following birds were collected and analyzed. The methodology involved a systematic literature review and in situ data collection, using platforms like Scopus and databases such as AVONET for functional traits of the species. Generalized Linear Models were applied to examine the relationship between latitude and biodiversity indices. The results of the study, which incorporated 32 relevant documents and information on 388 bird species, indicated that latitude is not a significant predictor of taxonomic and functional diversity. This suggests that the distribution of biodiversity is influenced by a range of other factors, potentially overshadowing the effect of latitude. The research also noted the presence of outliers, suggesting that unique ecological conditions or measurement errors may have affected the statistical analysis. The discussion of the work emphasizes that the effect of latitude on biodiversity is complex and cannot be simplified by a linear gradient. Biotic and abiotic factors, habitat heterogeneity, and the evolutionary history of the species are likely more impactful locally than latitude. Furthermore, the research highlights the need for a holistic approach to understand biodiversity patterns, considering multiple variables and the interaction among them. In conclusion, the study points to the importance of multifaceted and contextualized conservation strategies that consider the complexity of the Neotropical ecosystems. It reinforces that effective conservation requires an expanded understanding of biodiversity that goes beyond latitudinal gradients and includes the interaction of various environmental and biotic factors.
