Figure 4. — The Pearson correlation coefficient between the fitness of figs (viable seeds) and the fitness of pollinator wasps (offspring number) of cooperating species using a non-parametric estimation method. (a) Samples collected in the warm season (n = 218, March–October). (b) Samples collected in the cold season (n = 134, November–February). (c) Fitness correlation coefficient between seeds and wasp offspring as function of unused commons (vacant female flowers; n = 352, over years). (d) Fitness correlation coefficient between seeds and wasp offspring as function of wasp offspring (n = 352, over years). The bandwidth h is 400, which was obtained by cross-validation method.
