Figure 3. The relationship between A) Connectance, B) total species diversity, C) primary producer diversity and persistence for empirical webs.

Each point represents 100 replicated simulations with colonization rate c = 0.2 and extinction rates  = 0.05 and  = 0.05. The empirical webs are distinguished for the studies in which they were compiled: Cohen = ref. 49 Dunne = ref. 54 Havens = ref. 53.
