Main hypotheses, applied point pattern analyses, and related figures and tables used in this study

Hypotheses	Point pattern analyses and null models	Related figures and tables
(1) The spatial patterns and spatial distributions of congeneric species are similar	CSR and HP with g(r) function and RL within a case–control design with the g 21(r) − g 22(r) using species 1 as the control and species 2 as the case and with g′21(r) − g′22(r) using species 2 as the control and species 1 as the case	Figures 3, 4, 5, 6
(2) Interspecific competitions between congeneric species are weak	HP with bivariate g 12(r) function	Figure 7
(3) The interspecific correlations of each congeneric species with the noncongeneric species are similar on the same scales	RL with g 13(r) − g 23(r): 1 = one congeneric species, 2 = one of the other congeneric species, 3 = one of the noncongeneric species	Tables 2, 3, 4

CSR, complete spatial randomness null model; HP, heterogeneous Poisson's process null model; RL, random labeling null model.
