Herb production in plot 2 was associated to light availability and to
establishment success for Q. pyrenaica in July (Fig. 4), i.e. this species was especially
successful in zones with an abundant herbaceous cover.

Non spatial analysis of growth
Interspecific and site differences
Stem height varied across species and plot, being in general higher in plot 2 (P =
0.01) (Appendix S2). Q. suber seedlings were the tallest. Abovegroung biomass and
RGR a showed significant differences across species. Q. faginea had the highest
aboveground biomass and Q. pyrenaica the lower. RGR a was higher in Q. faginea and
Q. suber. Leaf area, LMF a and RGR t were similar in different species and plots
(Appendix S2).
Factors affecting growth and morphology
Seed mass was one of the best predictors for growth and morphology as it
appears in 39 % of the 48 models fitted (six variables per species and plot), being
practically the only factor selected in models of plot 1 (Table 5) (see also Appendix 3).
Figure 5 shows seed mass – aboveground biomass relations in plot 1.
