Seasonal Distribution of Phytoplankton In Laddia Dam In Sikar Disrict of Rajasthan
This paper reports on study carried out from January 2008 to December 2009 in Madhav Sagar pond. The study emphasizes the local and regional climatic influence on phytoplankton species composition, diversity and density variation in the pond ecosystem. In addition Nitrate, Inorganic phosphorous, Temperature, pH, Conductivity, Dissolve oxygen, Chloride, Total hardness, Calcium and Sodium were analyzed. The result obtained indicates that a significant difference in abundance of phytoplankton groups was found between year 2008 and 2009. Though the highest phytoplankton abundance was observed in July 2008 and February showed the highest number of taxa (highest diversity). Chlorophytes were the major dominant group in both periods.
