Published Paper Details:

Biodiversity indicates the variability among living organisms from all sources including inter alia terrestrial, marine and other aquatic eco-system and ecological complexes of which they are a part ; this includes bio-diversity within species, between species and of eco-systems. The three main components of biological diversity are (1) Genetic diversity :The Allelic variation within a species such as different rice varieties, different varieties of Babul, different varieties of cows, sheep etc. (2) Species diversity :This is the commonest method of measuring biological diversity which indicates total no. of species and their dominance. This also includes variation of different Taxa at various levels. Total no. of terrestrial species are much more than aquatic species. But total no. of terrestrial phyla is 50 whereas total no. of aquatic phyla is 52. (3) Eco-system diversity :The forest eco-systems are mostly highly diverse and within the forest eco-system Rain forests are more diverse than low rain fall areas or mangrove. This Paper shows the richness and threat to biodiversity in North east India and depict a overall picture of bio diversity in North east India.
