Figure 1. Annual rate of increase (%) and final population size (initial population size 10,000) for simulations with constant parameters (no annual variation), berry crop failures 1 year in 10, double the normal harvest rate 1 year in 10, and a combination of berry crop failures 1 year in 10 and double the normal harvest 1 year in 10. Five different harvest scenarios were simulated: S30 – spring season with 30% of harvest females, S35 – spring season with 35% of harvest females, F35 – fall season with 35% of harvest females, F40 – fall season with 40% of harvest females, and F45 – fall season with 45% of harvest females. Minimum and maximum values were obtained from 100 repetitions.
