Fig. 2. Boxplots of ALF (left) and UDF (right) grouped by ecological status, ω, and ecoregion. (A) ALF for all RWBs in Germany. (B) ALF for ecoregion Alps. (C) ALF for ecoregion Central highlands, (D) ALF for ecoregion Central plains. (E) UDF for all RWBs in Germany. (F) UDF for ecoregion Alps. (G) UDF for ecoregion Central highlands, (H) UDF for ecoregion Central plains. Dotted circles indicate median values. Vertical grey bars indicate significant differences between groups based on the non-parametric Kruskal-Wallis test. If there are no bars (e.g. 2C, ω>3)) there is no statistically significant difference between mean ranks of groups.
