Abstract

In the present study an attempt has been made to screen the algal samples from Nallacheruvu
located in Duddeda village of Medak district in Telangana state.The investigation was carried out
for a period of one year . In order to identify the algal groups, samples were collected every month
throughout the year during June,2013- July, 2014. The identified algal forms belonged to four
groups-Chlorophyceae, Cyanophyceae, Bacillariophyceae and Euglenophyceae. Growth of
Chlorophycean members was observed throughout the year, but luxuriant growth was recorded
during monsoon season. Cyanophycean members were found to be abundant during summer
season. Bacillariophycean members, the diatoms were dominant both during winter and summer
seasons. Members of Euglenophyceae showed maximum growth during rainy season and
Euglenophyceae was dominated by species of Euglena.
Key words: Algal groups, Algal forms, Aquatic Ecosystem, Lake waters, Lentic Environment.
