2.2 Conservation Biology — Test 2
Q1. Organisms that are restricted to a particular area and found nowhere else are called:✓ Endemic
Q2. Biodiversity hotspots are designated primarily on the basis of:✓ High endemism (and habitat loss)
Q3. A place is designated a biodiversity hotspot if its percentage of endemic vascular plants exceeds about:✓ 0.5% of the world total (≈1500 species)
Q4. In India, the recognised biodiversity hotspots include:✓ The Western Ghats and the North-Eastern (Eastern) Himalayas
Q5. High endemism is most characteristically shown by:✓ Islands
Q6. Which of the following is NOT an in-situ method of conservation?✓ Zoological gardens (zoos)
Q7. Which is an in-situ method of conservation?✓ Biosphere reserve
Q8. A conservation programme that protects an entire ecosystem and thus the whole 'trophic ladder' is best provided by:✓ A biosphere reserve
Q9. Wetlands of international importance are conserved through the:✓ Ramsar Convention
Q10. A programme used specifically to conserve species facing imminent extinction by breeding them in controlled conditions is:✓ Captive breeding
