Fig. 1: Distribution of community temporal trends per decade across sites.

a–f, Total abundance (a), species richness (b), proportion of non-native total abundance (c), proportion of non-native species richness (d), Simpson temporal dissimilarity (e) and Jaccard turnover (f). Temporal trends per decade were estimated from a hierarchical Bayesian model including time as sole fixed predictor and using a random slope to estimate temporal trends at each site (Methods). The histograms show the best linear unbiased predictor estimated at each site and the dots below the histograms represent the average posterior distribution with labels depicting the Bayesian CI at 95%. The dashed lines denote no temporal trend. N = 46,932 sampling events across 4,476 sites.
