Community metrics. Macroinvertebrate communities were sampled annually across New Zealand rivers over 30 years at 66 sampling sites. (a) Communities show overall a slight increase in richness through time. (b) Species evenness was also unchanged through time. (c) Species identity changes in communities were steady over time with relatively high turnover rates. (d) Species gains and losses were negatively correlated in each community (measured as the Spearman’s correlation) (e) with various levels of mutual dependence (dashed orange lines indicate the average value).
