Fig. 3

Observed O(r)-statistic estimates for univariate analysis of individuals of Phalaenopsis pulcherrima at each of the three sub-populations a YJM-A, b YJM-B, c YJM-C and d the whole population YJM. bLO(r) represents the slope of the linear regression of the O-ring statistic, O(r) against log spatial distance, ln(r). Envelopes defined by the 5% highest and lowest values generated from 999 Monte Carlo simulations under the null hypothesis of complete spatial randomness (CSR) are indicated by grey lines. The thin solid line indicates the first-order intensity (λ) of the point pattern within (sub-)populations: 0.0035 in YJM-A, 0.0027 in YJM-B, 0.0160 in YJM-C and 0.0018 for YJM as a whole. ***p < 0.001
