ABSTRACT Global change will create new species interactions and alter or eliminate existing ones, a process known as interaction rewiring. This rewiring can significantly affect how ecosystems function. To better predict the future structure of ecological networks, assessing their ability to adapt changes is crucial. Here, we introduce two concepts: ‘rewiring capacity’ single (the multidimensional trait space all its potential partners within region) potential’ local community total covered by at target trophic level locally). quantify capacity potential, apply methods for determining species' functional niches in novel way assess communities' form resilience networks global change. illustrate applicability these concepts, quantified between 1002 flowering plant 318 hummingbird across Americas. The metrics offer understand network resilience, allowing us map respond

Abstract Functional traits determine interactions between plants and pollinators, to increase pollination efficiency, many have evolved attract specific pollinator groups. However, biogeographical setting may influence trait evolution biotic interactions. For instance, pollinated by hummingbirds often ornithophilous traits, that is, flowers with elongated corollas, dilute nectar red colours, but—due colonization history, depauperate biotas unstable environmental conditions—it might be disadvantageous for species rely on mutualistic partners functional oceanic islands. Hummingbird‐visited islands are thus expected fewer functionally less diverse in their hummingbirds. We compiled an extensive dataset of plant—hummingbird (1030 plant 181 hummingbird species) associated traits. divided the data into four regions across American mainland Caribbean then tested whether differed proportion floral diversity found hummingbird‐visited communities displayed lowest typically a adaptation towards bird‐mediated pollination, average shortest highest concentrations largest non‐ornithophilous colours. Contrary our expectations, interacted were morphologically more distinct than regions. Overall, we document strong imprint insularity While support island theory, predicting systems islands, plant–hummingbird was higher mainland, possibly driven competition over resources.
