Abstract

The algal diversity of the Ganikere tank of Sagara town of Shivamogga district was studied for a period of six months from January to June 2007. During the period of investigation 79 species of phytoplankton representing five main taxonomic groups such as Chlorophyceae, Cyanophyceae, Euglenophyceae, Bacillariophyceae and Desmids were recorded. Relative abundance of phytoplankton in Ganikere tank showed maximum of Bacillariophyceae (34.17%), followed by Chlorophyceae (29.11%), Cynophyceae (17.72%), Euglenophyceae (12.65%) and Desmids (6.32%). Microcystis aeroginosa, Merismopedia glauca, Euglena gracilis and Scenedesmus quadricauda were the common pollution indicators.

... These phytoplanktons directly provide fabricating material for constructing the nests by the birds inhabiting there and indirectly provide food for them. [4] studied the phytoplankton diversity of lentic water bodies. [5] studied the monthlies variations in phytoplankton density and [6] performed the limnological studies in this Alwara lake. ...

Alwara Lake is located in Kaushambi district of Uttar Pradesh. This lake is one of the perennial wetland (water logged area), biota of which is influenced by several physico-chemical parameters. The said lake has a vast dynamic landscape which is created by annual flooding of adjacent river Yamuna. In this water ecosystem, phytoplankton is major producers which fix energy and transfers to the land. Present investigation is an attempt to assess some phytoplankton families and monthlies variations in their density. Present study will not only attract the biologists for further study but also help to frame appropriate strategy for the development of Wetland (Alwara Lake). ABSTRACT
... The higher values of oxygen are associated with rise of phytoplankton population (Bhatt and Negi, 1985). Since the occurrence of an indicator species can reflect either clean or polluted conditions; indicator organism cannot be sensitive to all types of pollution (Hosmani, 2010;Vasantha Naik et al., 2012;Sayeswara, 2014). ...

An attempt has been made to assess the phytoplankton diversity of Karamana and Neyyar rivers of southern Kerala, with special reference to nutrients. Studies revealed 23 genera of phytoplanktons from Neyyar and 20 from Karamana river. Members of Chlorophyceae were found to predominate in the two rivers. Genus representing Desmidiaceae, Bacillariophyceae and Cyanophyceae was also noticed in the two rivers. Species diversity was found to be higher in the upstream. The nutrients present in Karamana river ha positively influenced the growth and distribution of members belonging to Cyanophyceae. In Nayyar river, only nitrate had positively influenced the growth of phytoplankton belonging to Bacillariophyceae, Cyanophyceae and Desmidiaceae.

The physico-chemical parameters and planktonic composition of Hosahalli pond were studied for a period of twelve months from January to December 2010. The estimated water quality parameters were compared with standard values prescribed by the Bereau of Indian standard (BIS) and World Health Organization (WHO). The results of physico-chemical analysis revealed that water is polluted as it possess high BOD, free CO2 and phosphate. Conclusively these parameters along with other physico-chemical characteristics were found to be affected by surface run-off and other excessive human activities. A total of 60 species belonging to 43 genera of phytoplankton were recorded, of which chlorophycean and diatoms were found to be dominant among four classes. Eleven zooplankton were indentified.

No correlation was noted between physico-chemical parameters (ambient water temperature, pH, DO, free CO2, carbonate, bicarbonate and total alkalinity) and the plankton population. Highest phytoplankton numbers were observed during September-October, highest zooplankton in December-February. -from Authors

The present paper deals with abundance, periodicity and composition of phytoplankton in relation to physico-chemical factors of fish pond at Anjale, Dist. Jalgaon, Maharashtra. It was observed that members of Bacillariophyceae were dominant amongst other algal groups. This dominance was followed serially by Chlorophyceae, Myxophyceae, Euglenineae and Dinophyceae.

A study was carried out in Matthur tank near Shivamogga city on Physico-chemical characteristics and Planktonic composition. The results of physico-chemical parameters were compared with the standard values prescribed by the Bureau of India Standards (BIS) and World Health Organization (WHO). The study revealed that tank water is polluted as it possesses high BOD, CO 2, phosphate and nitrogen. A total of 55 species belonging to 38 genera of phytoplanktons were recorded, of which chlorophycean and diatoms were dominant. Nine zooplanktons and twelve macrophytes were also recorded.

The spatial and seasonal variations in phytoplankton species composition and abundance in relation to physico-chemical properties were studied during Jan.-Dec. 1992. During the course of investigation, Biddulphiaceae, Coscinodiscaceae and Chaetoceraceae among Centrales and Naviculaceae among Pennales emerged as floristically rich families. A considerable variation was noticed with respect to the species assemblages of different months. Population density of phytoplankton showed conspicuous seasonal variations. The cell counts varied between 9-759 × 103 cells I-1. Diatoms constituted the most dominant group followed by dinoflagellates. Occurrence of Asterionellopsis glacialis, bloom during April followed by the blooming of Peridinium sp. in May could be taken as the most striking feature of this study. Of the various environmental parameters studied, change in salinity and nutrient concentrations played major role in controlling the distribution and abundance of phytoplankton. Termination of bloom occurred due to depletion of silicate and nitrate from the water column.

In this note the Diatoms from the Gujarat College compound are systematically described and some notes or remarks are given on their occurrence, ecology and distribution in the region of Ahmedabad.While summarizing the results of the present investigation, the following could be stated:that with the exception of two small notes by the author there exists little information of the Diatomflora of Ahmedabad region.The diatoms of the present area are a special kind of biotopes characterised by small size. However, the causes leading to this nannism remain to be determined.The observations regarding Caloneis beccariana (Grun.) Cl. and Amphiprora paludosa W S m. v. subsalina Cl., found to be in close harmony with those of HUSTEDT and CLEVE, respectively and further it is confirmed that they are very variable species.The water of the present locality could be called somewhat brackish on the basis of a large number of salt-loving diatoms being found here. Moreover, they are all alkaliphilous even the new entities with the exception of two which are known to be indifferent for the pH.In light of the existing Halobion data and local observations some of the new entities and a few others are assigned their Halobion status. The spectrum relating to the same is also given.The distribution of these diatoms is indicated for the region of Ahmedabad.With regard to their periodicity recorded for over a year it was observed that almost all the species were perennials and a few among them showed slight rises any time from September to December.Lastly, in all twenty-three diatoms are recorded from the present area representing ten genera. Of these, six are new records for India and three species and one variety is considered to be new.

The phytoplankton samples were collected from the Veeranam lake for a period of one year from March-2005 to February-2006. The physico-chemical parameters of water such as air-temperature, water temperature, pH, salinity, dissolved oxygen, electrical conductivity and total dissolved solids were observed and their ranges were: 30.1-36.5 degrees C, 29.0-34.4 degrees C, 7.9-8.4, 1.2-2.5 mgl(-1), 7.6-9.2 microS and 2.5-5.2 mgl(-1). Totally 160 species of phytoplankton belonging to different taxonomic groups were identified. Among these 74 species to belong to Bacillariophyceae, 43 species to Chlorophyceae, 38 species to Cyanophyceae and 5 species to Euglenophyceae. The phytoplankton density was high (1705 cells l(-1)) during the summer season and low (760 cells l(-1)) during the winter season. Bacillariophyceae formed the dominant group. Species diversity index (H'), species richness (SR) and species evenness (J') were calculated.
