Floristic tudy of Algae nder he Ice overs in the Alpine Lakes of Arunachal S U T C Pradesh, India (Eastern Himalayas)

Abstract

Algal flora of five high altitude alpine lakes of Arunachal Pradesh, India (Eastern Himalaya) was documented below the ice cover soon
after the winter. A total of 66 taxa were recorded belonging to Class Chlorophyceae (22 taxa of 13 genera), Xanthophyceae (3 taxa of 3
genera), Chrysophyceae (1 taxon of 1 genus), Euglenophyceae (3 taxa of 2 genera), Dinophyceae (1 taxon of 1 genus) and
Bacillariophyceae (36 taxa of 19 genera). Out of these, 15 taxa were new records from India. Further comparative distributional study was
made between the biota near the ice cover and the bottom.
