Present Communication

The present communication is a part of survey being conducted to study the fresh water algal flora of Namchi, South Sikkim. Thirteen taxa of class Chlorophyceae, which include 8 genera, 10 species and 3 varieties, were identified from 6 samples. Spirogyra nitida (Dillw.) Link, Netrium digitus (Ehr.) Itzigs. and Roth. and Scenedesmus bijugatus (Turp.) Kuetz. were the dominant green algae followed by the remaining other rare species of Scenedesmus and Staurastrum. All these taxa constitute new records for the study area. Key words: Chlorophyceae, Fresh water algae, India, Namchi, Sikkim-Himalayadoi:10.3126/on.v3i1.334Our Nature (2005) 3: 50-55

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.

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.
