The correct answer is 1, 2, 3, 4, and 5.
Key-Points
- According to Myres, in order to declare a particular region as a biodiversity hotspot it must fulfil two important criteria:
- Such region must have at least 1,500 endemic vascular plants, including related fauna that are threatened (vulnerable, critical, and critically endangered species) and
- The region must have lost about 70% of its original natural vegetation.
- This region supports more than 50% of the plant species and nearly 43% of four vertebrate groups (Birds, Mammals, Amphibians, and Reptiles) species that are endemic, on just 2.3% of Earth’s land surface.
- So these regions show a high degree of genetic diversity among the species.
- Hence option 4 is correct.
Additional Information
- The concept was given by Norman Myres who originally gave an account of 25 Biodiversity hotspots.
- At present, there are 34 such spots identified (3 are in Indian Subcontinent).
- This demarcation of biogeographic regions gained popularity because conservationists lacked funding support to employ species conservation and protection strategies due to their vast spread across the globe and lack of funding.
- So with this approach, conservationists can focus their attention on areas with vast diversity in a particular region to protect as many threatened species and their habitat as possible - Myres referred to it as a Silver bullet strategy.
