Which one of the following is not observed in biodiversity hotspots ?
A
Lesser inter-specific competition
B
Species richness
C
Endemism
D
Accelerated species loss
Detailed Solution
Biodiversity hotspots are regions with very high levels of species richness and a high degree of endemism (species confined to that region and not found anywhere else).
They are also regions of accelerated habitat loss, so they show accelerated species loss and need priority in conservation.
So species richness, endemism and accelerated species loss are all observed in hotspots.
Because a very large number of species live together and share limited resources in these areas, the inter-specific competition is high, not less.
Hence lesser inter-specific competition is not observed in biodiversity hotspots.
There are 34 hotspots in the world; three of them (Western Ghats and Sri Lanka, Indo-Burma and Himalaya) cover the exceptionally rich biodiversity regions of India.
