Models for Benthic Predation

Models for Benthic Predation - Figure 3

Figure 3. The ODE model predictions over a range of values of the predator attack coefficient, q. The remaining parameters have the values given in Table 1. S₁^* is the lower stable equilibrium, S₂^* the middle unstable equilibrium, and S₃^* the upper stable equilibrium. (A) Two stable equilibria are present when the predator attack rate is at an intermediate value (q = 1). (B) When the predator attack rate is low (q = 0.1), only the upper stable equilibrium S₃^* exists. (C) When the predator attack rate is high (q = 10), only the lower stable equilibrium S₁^* exists. See Donalson et al. (2003, 604KB) for details.
