Ordination plots of canonical axes 2 vs. 1 from the RDA of periphyton FA composition for all samples from 17 study streams over two seasons in 2016 in the Ybbs catchment, Austria. (A) Ordination plots with FA responses; (B) Position of study streams in each season on the first two axes (RDA1 and RDA2); (C) Position of study streams relative to riparian canopy on the first two axes (RDA1 and RDA2).
