Effect of geographical distance on beta diversity after controlling for environmental variables The observed partial correlation coefficients of beta diversity with geographical distance (coordination) after controlling environmental heterogeneity were significant for total bryophytes ( r = .1493, p < .001), total mosses ( r = .1432, p < .001), liverworts ( r = .090, p < .02), pleurocarpous mosses ( r = .1257, p < .005), and marginally significant for acrocarpous mosses ( r = .0471, p = .072) (Table 3 ).
