dc.description.abstract | Indirect interactions are central to ecological and evolutionary dynamics in pollination
communities, yet we have little understanding about the processes determining patterns of
indirect interactions, such as those between pollinators through shared flowering plants.
Instead, research has concentrated on the processes responsible for direct interactions and
whole-network structures. This is partly due to a lack of appropriate tools for characterising
indirect interaction structures, because traditional network metrics discard much of this
information. The recent development of tools for counting motifs (subnetworks depicting
interactions between a small number of species) in bipartite networks enable detailed analysis
of indirect interaction patterns. Here we generate plant-hummingbird pollination networks
based on three major assembly processes – neutral effects (species interacting in proportion to
abundance), morphological matching and phenological overlap – and evaluate the motifs
associated with each one. We find that different processes produce networks with significantly
different patterns of indirect interactions. Neutral effects tend to produce densely-connected
motifs, with short indirect interaction chains, and motifs where many specialists interact
indirectly through a single generalist. Conversely, niche-based processes (morphology and
phenology) produced motifs with a core of interacting generalists, supported by peripheral
specialists. These results have important implications for understanding the processes
determining indirect interaction structures. | en_GB |
