Three of the following criteria have contributed to the recognition of Western Ghats-Sri Lanka and Indo-Burma regions as hotspots of biodiversity: Species richness, Vegetation density, Endemism, Ethno-botanical importance, Threat perception, Adaptation of flora and fauna to warm arid humid conditions. Which three of the above are correct criteria in this context?
- A.1, 2 and 6
- B.2, 4 and 6
- C.1, 3 and 5
- D.3, 4 and 6
▶ Answer & Explanation
Correct answer: C. 1, 3 and 5
Biodiversity hotspots are defined by two primary criteria: high species richness and a high degree of endemism. Additionally, these regions must be under significant threat of habitat loss. While vegetation density, ethno-botanical importance, and adaptation to conditions are relevant ecological factors, they are not the defining criteria for designating a region as a biodiversity hotspot by organizations like Conservation International.
