摘要：We present a conceptual framework that explores some of the forces creating innovationand novelty in complex systems. Understanding the sources of variability and novelty may help us betterunderstand complex systems. Understanding complex phenomena such as invasions, migration, andnomadism may provide insight into the structure of ecosystems and other complex systems, and aid ourattempts to cope with and mitigate these phenomena, in the case of invasions, and better understand andor predict them. Our model is broadly applicable to ecological theory, including community ecology,resilience, restoration, and policy. Characterizing the link between landscape change and the compositionof species communities may help policymakers in their decision-making processes. Understanding howvariability is related to system structure, and how that generates novelty, may help us understand howresilience is generated. We suggest that there are three primary opportunities for the generation of noveltyinto complex systems. These sources of novelty are inherent in the cross-scale structure of complex systems,and are critical for creating adaptive capacity. Novelty originates from the inherent variability present incross scale structures, within scale reorganization associated with adaptive cycles, and whole-scaletransformations resulting from regime shifts. Although speculative, our ideas are grounded in research andobservation, and they may provide insight into the evolution of complex systems
