Fig. 6. The novelty cycle in discontinuous panarchical systems is analogous to the taxon cycle described by Wilson (1961). Variability in resources (line above the x axis that represents the discontinuous body mass distribution of species) is highest at scale breaks, as in Figure 5. In time step one, novel behaviors or species (black) are added at scale breaks. As time progresses (time step two) the novel behaviors or species have ‘migrated’ towards the center of body mass aggregations where resources are less variable. By step three, this migration has completed. In time steps two and three new novelty is being introduced at the edges (grey). This diagram does not show the increased extinction rates also expected to be associated with scale breaks.
