Interspecific associations of Quercus serrata var. brevipetiolata (QS), Q. variabilis (QV), and Q. aliena var. acutiserrata (QA) in Plot 1 (a and b) and in Plot 2 (c, d, and e). The g ₁₂(r) and heterogeneous Poisson's process null model are used to calculate interspecific associations of Quercus species. To generate 99% confidence envelopes (gray solid lines), 199 Monte Carlo simulations are used. The black solid line indicates the observed value, and the black dashed line indicates the theoretical value
