These pigments include compounds that allow discrimination of cryptophytes
(alloxanthin), diatoms (diatoxanthin), dinoflagellates (peridinin), cyanobacteria (zeaxanthin), filamentous cyanobacteria (myxoxanthophyll, oscillaxanthin), chlorophytes (lutein, Chl b, and derivatives), as well as chromophytes (chrysophytes, diatoms, some dinoflagellates; fucoxanthin, Chl c).
In his classification, there are five major classes, arranged according to increased protection of the regeneration buds: phanerophytes, chamaephytes, hemicryptophytes, cryptophytes
, and therophytes.
According to our findings, having some elements such as cryptophytes
and phanerophytes abundantly and in high percentage reveals the characteristics of temperate forests.
The presence of cryptophytes
and hemicryptophytes was the result of heavy grazing pressure that led the plants to reproduce and regenerate mostly through underground parts, irrespective of the climatic conditions acting there upon.
Hemiselmis virescens and Plagioselmis prolonga gave a negative relationship with TP and DIP and a positive relationship with temperature.
For example, the relative contribution of chlorophytes, cryptophytes
, and diatoms to the total chlorophyll a pool was strongly controlled by periods of elevated river flow (Figure 2).
Diatoms were the most abundant and diverse algal organisms (359 taxa), followed by chlorophytes (121), Cyanobacteria (42), euglenophytes (31), xanthophytes (14), chrysophytes (12), rhodophytes (6), dinophytes (6), and cryptophytes
Phylum 2 Cryptomonada (Cryptophyta, Cryptophytes
, Flattened Asymmetric Unicells, Usually Photosynthetic and Motile)
and dinoflagellates were rare throughout the experiment.
, chrysophytes, and dinoflagellates are usually rich in both EPA and DHA; diatoms are rich in EPA; and cyanobacteria and green algae contain no or little EPA and DHA (Naddafi et al.
This second group was dominated by Cryptophytes
(Chryptochrysis minor and Chroomonas sp.
Analysis of carotenoid alloxanthin allows for the distinguishing of the relative importance of cryptophytes

and other microflagellates as couplers in planktonic community dynamics.
3], Secchi, total suspended solids (TSS), and biomass of cryptophytes
(Bcry) were slightly negatively skewed, while specific conductivity (Cond) and number of species (Nsp) were slightly positively skewed.
