biology descriptiom

1. Flagellates and ciliates are the two major groups observed
during one year study
 Total of 52 species encountered of which 17 species
flagellates and 35 species ciliates
 Flagellates mainly cryptomonads, dinoflagellates and
euglenoids
Ciliates belonging to prostomatians, oligotrichs,
gymnostomatians
Numerically flagellates outnumbered ciliates
Species composition and abundance do not varied much
spatially.
Seasonally flagellates were numerically abundant during
pre-monsoon and post monsoon periods and ciliates
followed the flagellate abundance

2. • Cluster analysis revealed two assemblages of flagellates
and three assemblages of ciliates
• Flagellate assemblage 1. belongs to euglenoids and 2.
cryptomonads
• Ciliate assemblage mostly by Oligotrichs and
prostomatians. Halteria grandinella and strobilidium sp.
Are most abundant species observed during the study
• How ever the damside protozoan community differed from
catchment area with more existance of indicator species
like Coleps hirtus and vorticella natans at station 1 and
oligitrichs at catchment areas.
