Macroalgal indicator species and non-reproducing “morphospecies”, evaluated using indicator species analysis for stream bioassessment in California, which require qualitative sampling and large amount of material for species identification. Indicator classes are defined for total dissolved phosphorus (TP low <10 μg·L-1high >100 μg·L-1), total dissolved nitrogen (TN low <0.2 mg·L-1, high >3 mg·L-1), dissolved organic carbon (DOC low <1.6 mg·L-1, high >8.3 mg·L-1), dissolved copper (Cu low <0.3 μg·L-1, high >1.7 μg·L-1) and “reference” conditions (algal taxa selected from Fetscher et al., 2014).
