Size distributions of uninfested (solid line) and infested (dashed line) crinoids from one simulation of the neutral scenario (growth rate infested = growth rate uninfested). In this simulation, there were 37 infested (average size = 4.12 mm; SD 0.61; solid, vertical line) and 143 infested (average size = 3.35 mm; SD 0.52; dashed, vertical line) specimens. Values used in simulation: m = 0.1; i = 0.025; von Bertalanffy parameters S∞ (asymptotic size) = 6; b (scaling factor) = 0.67; K (rate at which asymptotic size is approached) = 0.05. See “Appendix” for details of the von Bertalanffy equation
