   FIG. A1. Functions describing density dependence in prey fertility (a) and prey dependence (via number of predator kills) in predator fecundity (b). Here, upsilon and gamma are shape parameters describing the strength of density dependence, and fmax and Fmax are maximum fertilitiy values for the prey and predator, respectively.
