TY  - JOUR
AB  - A persistent challenge in ecology is to tease apart the in-fluence of multiple processes acting simultaneously and interactingin complex ways to shape the structure of species assemblages. Weimplement a heuristic approach that relies on explicitly defining speciespools and permits assessment of the relative influence of the mainprocesses thought to shape assemblage structure: environmental filtering,dispersal limitations, and biotic interactions. We illustrate ourapproach using data on the assemblage composition and geographicdistribution of hummingbirds, a comprehensive phylogeny and morphologicaltraits. The implementation of several process-based speciespool definitions in null models suggests that temperature—but not precipitationor dispersal limitation—acts as the main regional filter of assemblagestructure. Incorporating this environmental filter directly intothe definition of assemblage-specific species pools revealed an otherwisehidden pattern of phylogenetic evenness, indicating that biotic interactionsmight further influence hummingbird assemblage structure.Such hidden patterns of assemblage structure call for a reexaminationof a multitude of phylogenetic- and trait-based studies that did not explicitlyconsider potentially important processes in their definition ofthe species pool. Our heuristic approach provides a transparent wayto explore patterns and refine interpretations of the underlying causesof assemblage structure.
