“…As a result we studied known localities as well as find new localities not only for algal diversity update but especially for charophyte macro-algae revealing. In present time we revealed 14 charophyte species (16 with ifraspecific variety) that known for Israel (Romanov and Barinova 2012;Romanov et al, 2015) from references and our studies. Last year research in Israel let us too includes few new localities, algal diversity of which has been never studied before (Barinova and Romanov, 2014a,b;2015a,b,c).…”

First study of new locality the Ga’aton River, the Lower Galilee, with charophyte algae, in semi-arid to temperate region of Israel has been implemented for revealing of algal diversity and ecological assessment of the water object environment by bio-indication methods. Altogether twenty species from five taxonomic Divisions of algae and cyanobacteria including one of them macro-algae Chara grovesii B.P. Pal were revealed in the Ga’aton River. This is the first species record for Israel and Mediterranean region. Chara was found in growth in the middle part of studied stream. Bio-indication and chemical variables characterize the charophyte sites environment as fresh, low alkaline, and low to middle organic pollution with mainly eutrophic state. Saprobity index S is fluctuated in small range (1.83-1.93) and reflect low to middle organic pollution, Class III of Water Quality. The river environment can be characterize as natural to anthropogenically impacted from the river basin with Aquatic Ecosystem State Index WESI about 0.50-0.57 and tendency of self-purification down the river. The Ga’aton River can be recommended for regularly monitoring of chemical and biological variables in purpose the watershed management and protection.

“…The charophytes (Charales, Streptophyta) as macroscopic autotrophic algae may be very important components of vegetation in several types of water bodies and may be used as a bio-indicator of ecosystem state, water quality, and ecosystem recovery and reservoir management efficiency. In present time we revealed 14 charophyte species (16 with ifraspecific variety) that known for Israel [3,4] from references and our studies. Last year research in Israel and Eastern Mediterranean let us too includes few new localities, algal diversity of which has been never studied before [5][6][7][8][9][10].…”

First study of new locality the Milkha Stream, the Lower Jordan River tributary, with charophyte algae, in semi-arid region of Israel has been implemented for revealing of algal diversity and ecological assessment of the water object environment by bio-indication methods. Altogether forty seven species from five taxonomic Divisions of algae and cyanobacteria including one of them macro-algae Chara gymnophylla A. Braun were revealed in the Milkha stream. Chara was found in growth in the lower part of studied stream but away from community in followed years. Bio-indication and chemical variables characterize the charophyte site environment as fresh, low alkaline, and low to middle organic pollution with mainly eutrophic state. Saprobity index S is fluctuated in small range (1.32-2.06) and reflect low to middle organic pollution, Class II-III of Water Quality. Statistical analysis divide environmental variables to natural and anthropogenic and found that charophyte-related species prefer natural, whereas diatom dominants prefer polluted waters which increased during present study. The Milkha Stream studied site is recommended for regularly monitoring of chemical and biological variables in purpose the watershed protection.

“…All these studies were based only on morphotaxonomic analyses and limited ecological data. Over the last five years, multifaceted studies on the Egyptian stonewort flora, based on freshly-sampled and herbarium specimens and including a combination of molecular, morphological, and ecological data, were initiated [42][43][44].…”

Present-day information available on the charophyte macroalgae in Egypt, including their phylogenetic affinities, remains largely incomplete. In this study, nine charophyte populations were collected from different aquatic biotopes across the Egyptian Western-Desert Oases and Sinai Peninsula. All populations were investigated using an integrative polyphasic approach including phylogenetic analyses inferred from the chloroplast-encoded gene (rbcL) and the internal transcribed spacer (ITS1) regions, in parallel with morphotaxonomic assignment, ultrastructure of the oospore walls, and autecology. The specimens identified belonged to the genera Chara, Nitella, and Tolypella, with predominance of the first genus to which five species were assigned though they presented some interesting aberrant taxonomic features: C. aspera, C. contraria, C. globata, C. tomentosa, and C. vulgaris. Based on our integrative study, the globally rare species C. globata was reported for the second time for the whole African continent. The genus Nitella was only represented by N. flagellifera, and based on the available literature, it is a new record for North Africa. Noteworthy, an interesting Tolypella sp., morphologically very similar to T. glomerata, was collected and characterized and finally designated with the working name ‘Tolypella sp. PBA–1704 from a desert, freshwater wetland’, mainly based on its concatenated rbcL+ITS1 phylogenetic position. This study not only improved our understanding on the diversity, biogeography and autecological preferences of charophytes in Egypt, but it also broadened our knowledge on this vulnerable algal group in North Africa, emphasizing the need of more in-depth research work in the future, particularly in the less–impacted desert habitats.
