UGC NET Questions (Paper – 1)

A biodiversity hotspot is defined as an area with exceptionally high species richness and endemism that is experiencing significant habitat loss. Such regions are given high priority for conservation action. The concept draws attention to places where protection can yield large biodiversity gains. Therefore the description in the question matches a biodiversity hotspot.

Option A:
Biosphere reserves are large areas designated to promote conservation,development and logistic support under UNESCO’s Man and the Biosphere Programme. While many have rich biodiversity,they are not defined specifically by endemism and threat level. Hence this term is less precise than biodiversity hotspot for the stem.

Option B:
A biodiversity hotspot,by definition,combines high endemic biodiversity with severe threat. It is this combination that makes them urgent conservation priorities. Because the question emphasises both richness and threat,this is the correct answer.

Option C:
National parks are protected areas aimed at conserving wildlife and natural ecosystems. However not all national parks meet the strict criteria of hotspots regarding endemism and habitat loss. Thus this option does not necessarily fit the definition given.

Option D:
Sanctuaries mainly focus on protecting particular species,especially animals,often allowing limited human use. They too may or may not qualify as hotspots. Therefore sanctuary is not the most accurate term for the region described in the question.
