The architecture-environment-fecundity trajectories: effects of interactions between PC2abs1 - size (a) or PC1rel1 - crown proportions (b) or PCrel2 - slenderness (c) or PCabs2 - asymmetry (d), and percentage canopy openness (C_Open), on estimated fruit yield of rowan (F_mean); the lines show cross sections of the two-dimensional LOESS fits in Fig.\ref{682352}
