Abstract:
Ecological novelty, when conditions deviate from a historical baseline, is increasingly common as humans modify habitats and communities across the globe. Our ability to anticipate how novelty changes predator–prey interactions will likely hinge upon the explicit evaluation of multiple forms of novelty, rather than a focus on single forms of novelty (e.g., invasive predators or climate change). We provide a framework to assess how multiple forms of novelty can act, alone or in concert, on components shared by all predator–prey interactions (the predation sequence). Considering how novelty acts throughout the predation sequence could improve our understanding of predator–prey interactions in an increasingly novel world, identify important knowledge gaps, and guide conservation decisions in the Anthropocene.
