The study includes the epipelic algae in Hemren reservoir, for the period between Januarys to October 2000 .The samples were collected from three selected sites at north, middle and south of reservoir. A total of 96 taxa of epipelic algae were identified. The diatoms were the dominated by 82 taxa represented 85.4% of the total identified species, followed by blue-green algae (cyanophyta) of 6.3 taxa (6%), and then green algae (chlorophyta) of 5.2 taxa (5%). One species was recorded for each crysophyta, euglenophyta and pyrrophyta. The seasonal variation for the cell density showed two peaks during spring and autumn seasons. Few species were dominated during the most studied period such as Achnanthes minutissima, Navicula cryptocephala, N. cryptocephala var . veneta and Nitzschia palea .

1. The penetration of light into Windermere is dependent chiefly on the numbers of phytoplankton organisms in the epilimnion. 2. It appears that the greatest depth at which rooted aquatic plants can grow must therefore be affected by the abundance of phytoplankton. The rooted plants are most active during July and August. Observations show that at this time the presence of blue-green algae reduces the light intensity at the limit of submerged vegetation (4·3 metres) by more than 50 per cent.

The study includes the phytoplankton compositions in Alaaras Lake , in summer 2008 and winter , spring , summer 2009. Samples were collected from three selected sites at north , middle and south of lake. A total of 74 taxa of phytoplankton were identified . The diatoms were the dominated by 44 taxa represented 82.8% of the total indentified species, followed by green algae ( Chlorophyta ) of 20 taxa (8.5%), and blue green algae (Cyanophyta of 7 taxa (7.2%). Tow species were recorded of Pyrrophyta and one species of Euglenophyta .The seasonal variation for Diatoms density showed tow peaks during Autumn and summer. Few species were dominated during the most studied period such as Cocconeis placentula var. euglypta, Synedra fasciculata and Cymbell affinis .

In this paper, the taxonomy of the dinoflagellates found in Australian waters is given, and the species concept as applied to the group is discussed. It is suggested that the Linnaean species concept cannot be strictly applied to a group which has, as a whole, no known sexual process and of which the vast majority of forms has not been cultivated. The seasonal variation and fluctuations of dinoflagellates in Australian waters are considered. It is found that, as usual, the greatest number of species occurs in warmer waters. Dinoflagellates are regarded as excellent indicators of water masses, and in one example, i.e. west of Tasmania, subtropical dinoflagellates led to the postulation of a subtropical current flowing east from Cape Leeuwin to King I. This has recently been confirmed by the finding of warm-water turtles on the west coast of Tasmania. Dinoflagellates are not as important as diatoms or tropical blue-green algae in productivity, except on rare occasions, but do serve as food for certain groups, e.g. salps, tintinnids, etc. Some are halophytic, some holozoic, and some facultative. No single factor or set of factors can be adduced to explain dinoflagellate maxima. There is some evidence of a rhythm, which may be tidal, in Goniaulas digitale and also in G. catenella.
