摘要
Native bee diversity is poorly documented for many regions of the globe, particularly in the Neotropics. The available structured inventories in this biogeographical region provide reliable data, but they lack a comprehensive interpretation due to the absence of an effort to relate diversity and composition data with environmental variables. We aimed to answer the following questions: (1) Do abiotic factors explain variations in the richness, diversity, and composition of bee assemblages? (2) If so, which abiotic factors explain each of these community descriptors? We used a database comprising 33 systematic surveys of bee assemblages along eastern Neotropics. We found significant effect of abiotic variables on biotic diversity parameters and assemblage composition. Temperature annual range was the main abiotic predictor affecting bee richness and diversity, while composition was explained by annual mean temperature, temperature seasonality, temperature annual range, and by annual precipitation.
