Figure 3.
Community beta diversity and its components in Daiyun Mountain. (a) Displays the beta diversity (βsor), species turnover (βsim), and species nestedness (βsne) using presence-absence data. (b) Presents the Bray-Curtis distance (dBC), balanced variation (dBC-bal), and abundance gradient (dBC-gra) using abundance data.
