These species cannot be used as indicator for clean water quality as commonly believed. The protozoa can be actively participating in the energy transfer chain between nano-planktonic and higher plants in polluted wetlands. © 2017 Elsevier LtdIndicator; Pollution; Protozoa; Wetland[SDGs]SDG6[SDGs]SDG15Energy transfer; Indicators (instruments); Plants (botany); Pollution; Protozoa; Water quality; Wetlands; Higher plants; Tolerant species; Chemical oxygen demand; bioactivity; bioindicator; chemical oxygen demand; contaminated land; pollution monitoring; pollution tolerance; protozoan; water quality; wetland; Article; chemical oxygen demand; Cryptomonas; Cryptomonas erosa; Epistylis lacustris; Euglena; Euglena acus; Euglena axyuris; Euglena caudate; Euglena gasterosteus; nonhuman; pollution; priority journal; protozoon; Vorticella campanula; Vorticella convallaria; wetland; biochemical oxygen demand; Oligohymenophorea; water pollutant; water quality; Cryptomonas erosa; Embryophyta; Epistylis lacustris; Euglena; Gasterosteus; Lepocinclis acus; Protozoa; Vorticella campanula; Vorticella convallaria; water pollutant; Biological Oxygen Demand Analysis; Oligohymenophorea; Water Pollutants; Water Quality; Wetlandsjournal article10.1016/j.biortech.2017.02.0512-s2.0-85013428267https://www.scopus.com/inward/record.uri?eid=2-s2.0-85013428267&doi=10.1016%2fj.biortech.2017.02.051&partnerID=40&md5=4b17814a965900fbdfb258508c1dce79
