Localized neighborhood species mingling is correlated with individual tree size inequality in natural forests in South China

Table 2 Summary structure characteristics of the 22 observational natural forest plots. dbh, diameter at breast height; \({\widehat{\overline{M}} }^{(k)}\) and \({\widehat{\overline{T}} }^{(k)}\)—species mingling and size differentiation indices; and \({\widehat{\Psi}}^{(k)}\) and \({\widehat{\Upsilon}}^{(k)}\)—species segregation and size segregation indices. \(k\) = 4 was used to compute the nearest neighbor indices
