Establecimiento de cuatro especies de Quercus en el sur de la ...

Appendix S2. Means, standard deviations, ranges and aggregation indices (I a ) for the different variables related to growth and morphology for the four species in the
two plots. An aggregation index (I a ) less than 1 corresponds to a regular pattern and a near‐unity one to a random pattern. The spatial pattern is aggregated when I a
is significant and greater than unity (a P < 0.07, * P < 0.05, ** P < 0.01, *** P < 0.001, ns not significant). LMFa (leaf mass fraction aerial is the ratio of leaf mass to
aboveground biomass, RGR s (relative growth rate of stems), RGR a (relative growth rate of aboveground biomass), subscript t 1 and t 2 refers to spring and summer,
respectively. Different letters indicate significant differences (P < 0.05) across species at plot 1 (capital letters) and at plot 2 (lower case letters). No difference were
found between plots, except from stem height that was higher in plot 2 (P = 0.01). No letters indicate no significant differences.
