Food web rewiring in a changing world

Climate change is asymmetrically altering environmental conditions in space, from local to global scales, creating novel heterogeneity. Here, we argue that this novel heterogeneity will drive mobile generalist consumer species to rapidly respond through their behaviour in ways that broadly and predictably reorganize — or rewire — food webs. We use existing theory and data from diverse ecosystems to show that the rapid behavioural responses of...
