    <p>AIC values of the most likely models are shown in bold. Size, Abiotic, Biotic and All factors represent models with only tree size, tree size and abiotic factors, tree size and biotic factors, and all factors included, respectively. Very rare, rare, common, very common denote abundance classes with 1–100, 100–1000, 1000–5000 and >5000 individuals, respectively. Small, medium, and large tree size classes include individuals with 1–20 cm, 20–40 cm, and >40 cm dbh, respectively.</p

    <p><i>Circles</i> show the coefficient estimate for each parameter, with 2S.E. indicated by <i>horizontal lines</i>. “Ba” represents basal area. Asterisks represent the probability that the estimates are not different from zero: *<i>P</i><0.05, **<i>P</i><0.01, ***<i>P</i><0.001, ns not significant (<i>P</i>>0.05).</p
