Seasonal changes in zooplankton community structure in relation to physico-chemical factors at Kurnur Dam Dist. Solapur (MS)
Patil Sahebagouda S and Dr. Vitthal R More
In several studies it found that seasonal variation in physico-chemical factors has great influence on population density, diversity as well community structure of zooplactons. The similar study was made at Kurnur dam in Solapur district to know whether the locational factors influence the physico chemical thus affecting the Zooplankton community structure. Various physico chemical parameters like temperature, transparency, TDS, water hardness, nutrient load like phosphate, nitrate, sulphate etc were considered to correlate seasonal variation in zooplankton community structure. Of the Zooplanktons Rotifera dominated throughout the year over Copepoda, Cladocera and Ostracoda. Overall zooplanktons dominated in month of May and October and they were counted less in October and December. October low can be compared with habitat dilution with external runoff in the reservoir while temperature is important factor for winter low in December. Thus temperature is the important physical factors that govern the community either directly by influencing the population growth rate or indirectly that is by influencing other physicochemical parameters. Besides rainfall and quality of runoff influx influence the zooplankton community structure.
