In conservation biology, what is the term for regions that are prioritized for protection because they have exceptionally high levels of species diversity and endemism?

• A. Keystone species
• B. Trophic cascades
• C. Ecotones
• D. Biodiversity hotspots

Answer: (D)

Verified step by step guidance

1. Understand the concept of biodiversity hotspots: These are regions that are prioritized for conservation due to their exceptionally high levels of species diversity and endemism, meaning they contain species that are unique to that area and not found anywhere else.
2. Recognize the importance of biodiversity hotspots in conservation biology: Protecting these areas helps preserve unique ecosystems and prevent the extinction of rare species.
3. Differentiate biodiversity hotspots from other terms: Keystone species are individual species that have a disproportionately large impact on their ecosystem, trophic cascades refer to the ripple effects of changes in one trophic level on others, and ecotones are transition areas between two ecosystems.
4. Learn the criteria for identifying biodiversity hotspots: These regions typically have at least 1,500 species of vascular plants as endemics and have lost at least 70% of their original habitat.
5. Apply this knowledge to conservation efforts: Focus on protecting biodiversity hotspots to maximize the impact of conservation resources and preserve global biodiversity.
