In the Funil reservoir, the dominant functional groups varied over the study years, with a higher contribution of groups C, F and MP (Navicula sp.) in the first year, group J in the second year and groups C and Ws (Chrysophyceae Synura sp.) in the third year of monitoring.
(2003) to include the Synura species, which are sensitive to high light radiation and tolerant to environments rich in organic matter from plant decay.
The Chryophyceae were maximally represented by Synura 40, Bacillariophyceae by Synedra 48 and Myxophyceae by Anabaena 60 individuals 5ml-1 in the treated pond, and were absent in reference pond.

Studies on the genera Mallomonas, Synura, and other plankton in freshwater by the electron microscope.
Twenty-seven silica-scaled synurophycean and chrysophycean taxa from five genera, Mallomonas (14 taxa), Synura (10 taxa), Spiniferomonas (two taxa), Paraphysomonas and Chrysosphaerella (one taxon each) were observed from the 35 samples.
In 1994, the pond without fish was dominated by chrysophytes (mainly Dinobryon and Synura) and dinoflagellates (Peridinium) until the large nutrient pulse, when chrysophytes declined and were replaced by Gonyostomum.
With respect to taste and odor control, there are a number of studies reporting on the successful use of chlorine dioxide in the treatment of musty odors, fishy tastes and odors from Mallonmonas, and taste and odor problems associated with Anabaena, Asterionella, Synura, and Vorticella, as well as actinomycetes which are a source of geosmin and 2-methylisoborneol (MIB).|3,4,5~ A 1986 study which compared chlorine dioxide, chlorine, ozone, and potassium for removal of five specific taste and odor compounds from drinking water found removals ranging from 30 to over 50 percent for practical Cl|O.sub.2~ dosages and contact times.|6~ Chlorine dioxide has also been shown to be effective for treating tastes and odors associated with phenol and phenolic compounds.|7,8,9~

According to Bird and Kalff (1987, 1989), this explains the maxima of several chrysophytes (Dinobryon, Uroglena, Synura) that are often below the euphotic depth.
Although there are clear qualitative indications of greater pH values, especially in the profiles of Mallomonas caudata and Synura spinosa, the two pH-circumneutral species in these assemblages, only one change of CIpH exceeds the RMSE of the transfer equation (= 0.37).
