Algal Dynamics in Relation to Physico-Chemical Factors in a High Altitude Pond of Shillong,India

A one year phycological study of a high altitude pond has been made with a view to studying the algal dynamics as affected by physico-chemical characteristics of the water. This has revealed the presence of 34 genera of algae belonging to Chlorophyta, Bacillariophyta, Cyanophyta, and Euglenophyta. Chlorophytes were the most dominant and diatoms the most frequent representatives of algae. The community diversity along with water chemistry are indicative of the oligotrophic nature of this pond.
