Figure 3.5: Effect of plant-pollinator interactions on plant species richness with a high degree of
pollen carryover (B = 50). Boxplots show the proportional difference between species
richness with and without pollinators for 100 simulation runs. Species richness was defined
as the number of plant species with population sizes above the extinction threshold
(10 individuals) at equilibrium. Except for pollen carryover, the default parameter
values listed in Table 3.1 were used for this figure.

Figure 3.6: Effect of plant-pollinator interactions on plant species richness with a high amount of
nectar per plant (N = 4). Boxplots show the proportional difference between species
richness with and without pollinators for 100 simulation runs. Species richness was
defined as the number of plant species with population sizes above the extinction
threshold (10 individuals) at equilibrium. Except for the amount of nectar per plant,
the default parameter values listed in Table 3.1 were used for this figure.
