Figure 2.

log₂ of the mass of soil, plants, herbivores, and predators for four different models (“Control”= 3‐level no risk, “Risk” = 3‐level with risk, “Predation” = 4‐level no risk, “Risk & Predation” = 4‐level with risk). Panels on the left are for nitrogen and panels on the right are for carbon. Results are for 1000 random parameter (uniform distribution) sets that meet feasibility conditions (i.e., equilibrium stocks of N _i and C _i > 0) and risk models: α = 36, β = 6.5, no risk models: α = 36, β = 6.05.
