In his classification, there are five major classes, arranged according to increased protection of the regeneration buds: phanerophytes, chamaephytes, hemicryptophytes, cryptophytes
, and therophytes.
In the inflows, planktonic cryptophytes
from the genera Cryptomonas and Rhodomonas dominated in the biomass for most of the year.
The rest was taken up by cryptophytes
, mainly Cryptomonas spp.
Availability of cryptophytes
(only geophytes) and therophytes confirms the anthropogenic disturbance of the substrate.
and Phanerophytes life forms were dominated in the herbal and regeneration layers, respectively (Table 1).
Cyanobacteria, Euglenophytes, Chrysophytes and Cryptophytes
were present at the three sampling sites.
They also found cyanobacteria, chrysophytes and cryptophytes
were dominant at times while dinoflagellates, chlorophytes and euglenoids appeared occasionally abundant, but were relatively minor components on an annual basis.
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).

, 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., 2007).
