North East (NE) India, represented by seven sister states of Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland and Tripura, is a biodiversity hotspot and is ecologically represented by the Eastern Himalayan biome. This region is rich in diversity of a number of endemic flora and fauna. Noted level of biodiversity is present in the rivers and lakes of this region, and the valuable ecosystem provides livelihoods to millions of people. These water bodies harbour many species of microalgae, including cyanobacteria, some of which are beneficial while some others are harmful as they are known to produce cyanotoxins, which are injurious to humans and animals. Though this biodiversity-rich region comes under Indo-Burma hotspots (except Assam), its algal diversity record is minimal and there are no substantial data available on the assessment of toxicity of the cyanobacterial population of the region.

Abstract


North East (NE) India, represented by seven sister states of Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland and Tripura, is a biodiversity hotspot and is ecologically represented by the Eastern Himalayan biome. This region is rich in diversity of a number of endemic flora and fauna. Noted level of biodiversity is present in the rivers and lakes of this region, and the valuable ecosystem provides livelihoods to millions of people. These water bodies harbour many species of microalgae, including cyanobacteria, some of which are beneficial while some others are harmful as they are known to produce cyanotoxins, which are injurious to humans and animals. Though this biodiversity-rich region comes under Indo-Burma hotspots (except Assam), its algal diversity record is minimal and there are no substantial data available on the assessment of toxicity of the cyanobacterial population of the region.
