Figure 2: Box plots (median, quartiles, range and outliers) of pairwise similarities (Jaccard) between latitudinal bands in each year of the study.
From: Rapid biotic homogenization of marine fish assemblages

The trend line (OLS regression) is shown (r2=0.42, P<0.001). Years in which the mean pairwise similarity is below the overall mean are shown in red, and those above the mean in blue. (A similar pattern emerges if Bray–Curtis similarity is used. See Supplementary Figure 3).
