Redundancy analysis (RDA) showing the relationships between CWM values (red arrows) and environmental parameters (blue arrows) among control (C) and restored (N) sites for the one-month immersion period. Abbrevations: N = nitrites; COD = chemical oxygen demand; OM = organic matter; IM = inorganic matter; CHL = chlorophyll a concentration; FSB = food source “bacteria”; FSPPSM = food source “phagotrophic protists, small metazoans”; EPLF = ecosystem preference “lentic (freshwater)”; EPLLF = ecosystem preference “lentic and lotic (freshwater)”; EPS = ecosystem preference “soil”; HPBP = habitat preference “benthos, periphyton”; HPB = habitat preference “benthos”; HPP = habitat preference “planktonic”; MLFS = mode of locomotion “free-swimming”; MLC = mode of locomotion “crawling”.
