Boxplots display the median (thick bar), lower (0.25) and upper (0.75) quartile (gray box), minimum and maximum values (whiskers) and outliers of each dataset. Asterisks indicate significant differences between landscapes according to Tukey's posthoc test, significance levels as follows: *P < 0.05, **P < 0.01, ***P < 0.001.
