In the past few years considerable attention has been paid to the distribution of the microflora of the salt marshes at Gibraltar Point, Lincolnshire (National Grid reference TF 555576). During these studies it was observed (Turner, personal communication) that blue-green algae (Myxophyceae) were of frequent occurrence in soil samples from the region, but no analyses of the algal flora were carried out. It is well established, however, that blue-green algae are generally present in salt marsh regions (Chapman, 1960 a). Previous studies on the blue-green algae of British salt marshes are few, although detailed investigations have been carried out at Canvey and Ynyslas (Carter, 1932, 1933 a, b) and Scolt Head Island (Chapman, 1939). Some difficulty is experienced, however, in attempting to correlate these results with present day studies, mainly because of the widespread colonization of salt marsh regions within recent years by Spartina townsendii H. & J. Groves, and by the fact that few quantitative data are available. It is hoped that the present communication which is concerned with the blue-green algal flora of the New Marsh at Gibraltar Point, a region dominated by Spartina townsendii, will allow an assessment to be made of the flora prevailing in a developing salt marsh under present-day conditions.

The marine green algae were collected from Apor Seik, Pashyu Chaung, Chaytoryar Pagoda, Alè Seik, Auk Sei, and Kyunn Pyet or Cavendish Island along the Kalegauk Island from September 2016 to January 2017. In the study areas, salinity range and temperature regimes seawater were 26-27 ‰ and 29° C to 31° C, respectively. Mainly the present study had been made to know the diversity and distribution of marine green algae along the Kalegauk Island. Marine green algae were identified based on their internal and external morphological characters. The total 14 species could be recorded in Kalegauk Island. Of these species, almost all species were first new records for Kalegauk Island.Alson, it was concluded that all species would be the most diverse and abundant in Apor seik. Moreover, the present study could provide evaluating the impacts of marine green algae resources caused by infrastructures in the future.

The purpose of the study was to determine the degree of saprobity of the artificial extension of the Vytravki riverbed (left tributary of the Dubna river) in the Sergiev Posad district of the Moscow region, based on the taxonomic composition of the pelagial and littoral algal flora. For this purpose, the systematic position of algae was determined using a number of domestic and foreign sources, as well as using the electronic database AlgaeBase. The most attention was paid to common indicator types, according to the literature data. Algological samples were taken in accordance with generally accepted methods; the main part of the samples was processed immediately after collection on site, the rest of the material was fixed with a formalin solution and Prat medium for detailed study in laboratory conditions under a microscope. According to the results of the study of hydrobiological samples, the composition of algal flora in the summer-autumn period was determined. There is a large species diversity of algae, represented by most of the divisions characteristic of the Central part of Russia. The green, diatomaceous, and blue-green algae divisions were the most represented. Maximum species diversity was observed for the genera Scenedesmus (9 species) and Pediastrum (10 species). Diatoms are the second group in terms of frequency of occurrence of species that live both in standing water and in rheophilic conditions. Blue-green algae were represented by pelagic forms, with a small frequency of occurrence. Among them, the genera Anabaena (5 species) and Microcystis (3 species) are notable for their high species diversity. The algal flora of the pond was marked divisions, dinophyceae and kropotova, typical for oligotrophic and distrophic reservoirs, indicating a high quality water environment. The established hydrochemical parameters of the reservoir were normal and were similar to the reservoirs of Central Russia at the end of the growing season, which were not exposed to anthropogenic impact.

In this last instalment of the series, 78 desmid taxa belonging to four genera, namely Xanthidium (8 taxa), Arthrodesmus (3 taxa), Staurodesmus (11 taxa) and Staurastrum (56 taxa) have been recorded from different aquatic habitats located within the tea gardens at Srimangal, Maulvi Bazar. Of these, nine are described as new records for Bangladesh. An overall assessment of the algal flora of the study area reveals desmids as the single largest group consisting of 230 taxa out of 421 recorded algal taxa. The paper comments on the conservation potentials of the studied aquatic habitats as monitoring tools of land use pattern like tea-gardening.

<p>Algal flora of five high altitude alpine lakes of Arunachal Pradesh, India (Eastern Himalaya) was documented below the ice cover soon<br />after the winter. A total of 66 taxa were recorded belonging to Class Chlorophyceae (22 taxa of 13 genera), Xanthophyceae (3 taxa of 3<br />genera), Chrysophyceae (1 taxon of 1 genus), Euglenophyceae (3 taxa of 2 genera), Dinophyceae (1 taxon of 1 genus) and<br />Bacillariophyceae (36 taxa of 19 genera). Out of these, 15 taxa were new records from India. Further comparative distributional study was<br />made between the biota near the ice cover and the bottom.<br />Key words: Algae, Ice cover, Lake, Arunachal Pradesh</p><p> </p><p><span>DOI: </span><a id="pub-id::doi" href="http://dx.doi.org/10.21756/cba.v1i1.11021">http://dx.doi.org/10.21756/cba.v1i1.11021</a></p>
