Table 5 Results of linear effect models testing the effect of elevational distance for overall β-diversity (βsor) and the components turnover (βsim) and nestedness (βsne) performed separately for along elevation and stepwise β-diversity.

From: Species richness and β-diversity patterns of macrolichens along elevation gradients across the Himalayan Arc
