The algal samples belonging to Chlorophyceae
are collected from intertidal zones, Phaeophyceae from subtidal zones and Rhodophyceae from intertidal to subtidal zones.
Therefore, independently of substratum type, we verified the predominance of Zygnemaphyceae (desmids), followed by Bacillariophyceae (diatoms), Chlorophyceae
and Cyanophyceae (Table 1, Figure 4).
was found to be the most dominant class qualitatively and ranked second quantitatively.
Species richness was 31 taxa, with the classes Florideophyceae constituting 10 species, Phaeophyceae 9 species, and Chlorophyceae
10 species (Table 1).
Correlation coefficient between the total contents of the benthic pigments and characteristics of the corresponding water column indicated that it was positively correlated with Chlorophyceae

Diatoms predominated (30-50% of taxa richness) together with Chlorophyceae
(20-30%) and Chrysophyceae (15-25%).

A further distinction was found in the systematic distribution of the specific urea-utilizing enzyme (Al-Houty & Syrett, 1984; Syrett & Al-Houty, 1984); Charophyceae and land plants possess Urease; Chlorophyceae
and Ulvophyceae have urea amidolyase (UAL-ase).

During winter, Bacillariophyceae dominance was recorded, but density of other groups, such as Cyanophyceae, Chlorophyceae
and Zygnemaphyceae, was, in general, higher than densities registered during summer, mainly in intermediate and lower zones.
In Upper Lake bacillariophyceae species was found dominant while in Lower Lake chlorophyceae
species was found dominant in Lower Lake in almost all season (Bajpai et.
Most of the sandstone surface in this site is covered by epilithic lichens, with a dominance of those with Chlorophyceae
as phycobiont; cyanophilous lichens grow as well.
