Biodiversity & Conservation
Biodiversity
Immense diversity / hetergeneity
more than 20,000 species of ants, 3,00,000 species of beetles, 28,000 species of fishes and nearly 20,000 species of orchids
Popularised by Edward Wilson
Genetic diversity
medicinal plant Rauwolfia vomitoria - different Himalayan ranges - potency and concentration of the active chemical (reserpine)
50,000 strains of rice, and 1,000 varieties of Mango
Species diversity
Western Ghats have a greater amphibian species diversity than
the Eastern Ghats
Ecological diversity
AtIndia - greater ecosystem diversity
than a Scandinavian country like Norway
Biological levels of organization
Macromolecules within cells to biomes
Coined by Walter G. Rosen
Count
International Union for Conservation of Nature and
Natural Resources (IUCN) (2004) -
more than 1.5 million
**
species inventories are more complete in
temperate than in tropical countries
1. extreme estimates
range from 20 to 50 million
*
2. a more conservative and scientifically
sound estimate - Robert May - global species diversity is 7 million.*
in Total - >70% animals & 22% plants(including algae, fungi,bryophytes, gymnosperms and angiosperms)
Invertebrates - Indian Oil is more costly, Vertebrates - FB RAM, Plants - Anna who is family friend likes thambi
Prokaryotic species -
conventional taxonomic methods are not suitable for identifying microbial species
many not culturable under laboratory conditions
India's count
one of 12 Mega diversity country
land area in world - 2.4%, Global species diversity - 8.1%
Nearly 45,000 species of plants, animals are twice as that of plants
May’s global estimates - only
22 per cent of the total species have been recorded - If so, in India - more than 1,00,000 plant species and more than 3,00,000 animal species
yet to be discovered and described
