From: Long-term trends in stream benthic macroinvertebrate communities are driven by chemicals
Annual trends of macroinvertebrate taxonomic and trait metrics at four study sites in springs (a, c, e, g, i, k, m, o, q) and summers (b, d, f, h, j, l, n, p, r) from 2007 to 2021 using Generalized Additive Models. Abundance—total abundance, Shannon diversity metric, FRic—Functional Richness, FDis—Functional Dispersion, FRed—Functional Redundancy, LIFE—Lotic-Invertebrate Index for Flow Evaluation, KLIWA—water temperature preference metric, BMWP—Biological Monitoring Working Party. Significant temporal changes of metric values at each study site are represented by solid lines
