Figure 2. Effects of A) connectance, B) diversity, and C) colonization rate on persistence for webs generated with the niche model and random structures.

Each point represents 100 replicated simulations. Parameters are: A) c = 0.2,  = 0.05,  = 0.05, total diversity = 75 species with 5 primary producers; B) c = 0.2,  = 0.05,  = 0.05, connectance = 0.1 and the proportion of primary producers over total diversity is 0.2; C)  = 0.05,  = 0.05, total diversity = 75 species with 5 primary producers and connectance = 0.01.
