abstract
The present study was carried out in Waribok stream of West Garo Hills, Meghalaya. The algal flora of this region is unexplored. The stream ecosystem harbors a diverse group of algae. Maximum numbers of species were recorded from downstream (121 species) as compared to upstream (78 species). In both the study sites species richness was high in Bacillariophyceae and Zygnematophyceae member during spring and winter seasons. Primary Productivity and phytoplankton chlorophyll a content were maximum in downstream during winter season with 1.09 gC/m³/h and 0.35 mg/l respectively and showed strong positive correlation with cell abundance and N:P ratio and negative correlation with water current.
