Beyond neutral and forbidden links: morphological matches and the assembly of mutualistic hawkmoth–plant networks

Summary A major challenge in evolutionary ecology is to understand how co‐evolutionary processes shape patterns of interactions between species at community level. Pollination of flowers with long corolla tubes by long‐tongued hawkmoths has been invoked as a showcase model of co‐evolution. Recently, optimal foraging models have predicted that there might be a close association between mouthparts' length and the corolla depth of the visited...
