Influence of plant–pollinator interactions on the assembly of plant and hummingbird communities

摘要: Summary Understanding how ecological processes structure species assemblages is a central issue in community ecology. While the influence of plant-pollinator interactions on each other's evolution well recognized, their role assembly interdependent communities plants and pollinators still unclear. Using data from seven hummingbirds that they pollinate two tropical rainforest types (lowland montane), we evaluated phylogenetic relationships signal functional traits, over space time, to test predictions main (environmental filtering, facilitation or competition) are driving these hummingbird-plant assemblages. Our findings suggest varied between habitats, even among at same habitat. The non-conserved floral trait patterns (even random) give support hypothesis competition as regulating composition plant assemblages. Moreover, positive relationship fitness flowering synchrony suggests most important mechanism for montane communities. Distinctively, lowland communities, combination traits clustered may be result either adaptive radiation biotic filtering driven by particular pollinator plays organizer. Lastly, evidence conservatism, together with patterns, drive hummingbird despite predominance random patterns. Synthesis. Overall present pathway identify We show different related pollination vary time contribute pollinators. These highlight importance considering when evaluating processes.
