10. Which of the following is an example of ex situ conservation? — Maintaining a seed bank
11. Conservation biology employs various strategies. What is habitat restoration? — Rehabilitating degraded ecosystems to their former or a more functional state
12. Bioprospecting refers to the exploration of biodiversity for commercially valuable genetic and biochemical resources. What is a key ethical consideration in bioprospecting? — Fair and equitable sharing of benefits derived from these resources
13. What is the primary challenge associated with conserving species that have very low population densities or fragmented distributions? — Maintaining genetic diversity and avoiding inbreeding depression
14. Which of the following is NOT a level of biodiversity? — Atmospheric diversity
15. Which of the following is a major threat to biodiversity? — Habitat destruction and fragmentation
16. Pollution, in its various forms (e.g., chemical, noise, light), can negatively affect biodiversity by: — Disrupting natural processes and harming organisms
17. Overexploitation of species, such as overfishing or excessive hunting, leads to: — Population decline and potential extinction
18. What is the term for a species that has a critical role in maintaining the structure of its ecological community, such that its removal would cause a significant shift in biodiversity? — Keystone species
19. Ecosystem diversity encompasses the variety of: — Habitats, communities, and ecological processes
20. What is 'reintroduction' in the context of conservation? — Releasing captive-bred or wild-collected individuals into an area where the species no longer exists
21. An umbrella species is a species selected for conservation planning whose conservation will lead to the protection of a large number of other species. Which of the following is a characteristic of an umbrella species? — It has a large home range and requires diverse habitats.
22. Why is genetic diversity important for a species' ability to adapt to environmental changes? — It provides a wider range of traits, increasing the probability that some individuals will survive and reproduce under new conditions.
23. What is the significance of the 'Phylogenetic Diversity' metric in conservation? — It measures the evolutionary relatedness among species, aiming to conserve evolutionary history.
24. Climate change is a growing threat to biodiversity. How does it impact ecosystems? — It causes shifts in species ranges and can lead to mismatches in ecological interactions
25. Which of the following is a major challenge in conservation biology? — All of the above
26. In situ conservation refers to conservation efforts that occur: — Within the species' natural habitat
27. Which of the following is an example of a provisioning ecosystem service? — Provision of timber and food
28. Ecosystem services are the benefits that humans derive from ecosystems. Which of the following is an example of a regulating service? — Climate regulation (e.g., carbon sequestration)
29. What is the concept of 'biodiversity hotspots'? — Regions with exceptionally high biodiversity and significant habitat loss
30. Species diversity refers to the number and abundance of different species in a given area. What is the term for the number of species? — Species richness
31. What is 'ecological succession' in the context of habitat restoration? — The process by which an ecological community changes over time, often used as a model for restoring degraded areas
32. Which international agreement aims to prevent the illegal trade in endangered species of wild fauna and flora? — CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora)
33. The concept of 'allee effect' in conservation biology refers to: — The decline in individual survival and/or reproduction rates at low population densities
34. The term 'biomagnification' refers to: — The increasing concentration of a substance, such as a toxic chemical, in organisms at successively higher levels in a food chain
35. What is meant by 'fragmentation' of habitat? — The division of a large, continuous habitat into smaller, isolated patches
36. What is a 'biodiversity offset ratio'? — A multiplier applied to the conservation outcome required to compensate for a biodiversity impact, often aiming for 'no net loss' or 'net gain'
37. What is the primary focus of biodiversity? — The variety of life in a particular habitat or ecosystem
38. Which of the following is a major biodiversity hotspot in India? — The Western Ghats
39. Species evenness is a component of species diversity. It describes: — The relative abundance of different species
40. Genetic diversity is crucial for the long-term survival of a species. It refers to: — The differences in genes within a population
41. What is the primary difference between a 'threatened' species and an 'endangered' species on the IUCN Red List? — Threatened is a broader category encompassing several risk levels, while endangered is a specific high-risk category.
42. What is the primary goal of a 'wildlife corridor'? — To connect fragmented habitats, allowing species to move between them
43. What is the primary purpose of a 'biodiversity action plan' (BAP)? — To outline strategies and actions to conserve specific species or ecosystems
44. What is the role of 'community-based conservation'? — To involve local communities in the planning and management of conservation initiatives, recognizing their role and dependence on local resources
45. What is the purpose of establishing protected areas like national parks and wildlife reserves? — To conserve biodiversity and natural ecosystems
46. What is the role of gene banks in conservation biology? — To preserve genetic material (like seeds, sperm, or eggs) for future use
47. What is the main goal of conservation biology? — To preserve biodiversity and prevent species extinction
48. The Convention on Biological Diversity (CBD) is an international treaty. What is its main objective? — To conserve biological diversity, use its components sustainably, and share the benefits arising from the utilization of genetic resources
49. The 'Precautionary Principle' in conservation suggests: — To take protective measures even if scientific evidence of harm is not conclusive, especially if there is a risk of serious or irreversible damage
50. Ex situ conservation refers to conservation efforts that occur: — Outside the species' natural habitat
