………….is not generally seen in biodiversity hotspots.

Options

A. Endemism
B. Species richness
C. Loss of diversity
D. Lesser interspecific competition.

Answer

To solve the question, we need to identify which option is not generally associated with biodiversity hotspots. Let's analyze each option step by step:

1. **Understanding Biodiversity Hotspots**:
- Biodiversity hotspots are regions that are rich in endemic species (species that are not found anywhere else) and have a significant level of species richness. They are crucial for conservation efforts because they contain a high number of species that are threatened by habitat loss and other factors.

2. **Evaluating the Options**:
- **Option 1: Endemism**: This refers to species that are native to a specific area and not found elsewhere. Biodiversity hotspots are characterized by high levels of endemism. Therefore, endemism is generally seen in biodiversity hotspots.
- **Option 2: Species Richness**: This term refers to the number of different species present in a particular area. Biodiversity hotspots are known for their high species richness. Thus, species richness is also generally seen in biodiversity hotspots.
- **Option 3: Loss of Diversity**: This implies a reduction in the number of species or genetic diversity within an area. Biodiversity hotspots are areas of high diversity, not loss. Therefore, loss of diversity is not generally seen in biodiversity hotspots.
- **Option 4: Lesser Interspecific Competition**: Interspecific competition occurs between different species. In biodiversity hotspots, there is often a high level of competition due to the presence of many species. Therefore, lesser interspecific competition is not generally seen in these areas.

3. **Conclusion**:
- After evaluating all the options, the one that is not generally seen in biodiversity hotspots is **Option 3: Loss of Diversity**. Biodiversity hotspots are characterized by high diversity, not a loss of it.

### Final Answer:
Loss of diversity is not generally seen in biodiversity hotspots.
