Which of the following character is not related to biodiversity hot spot?

Options

A. High degree of endemism
B. Habitat loss
C. Lesser interspecific interaction
D. High species richness

Answer

To determine which character is not related to biodiversity hotspots, we can analyze the options provided:

1. **High degree of endemism**: Biodiversity hotspots are characterized by a high degree of endemism, meaning they contain many species that are not found anywhere else in the world. This is a key feature of biodiversity hotspots.

2. **Habitat loss**: Biodiversity hotspots often experience significant habitat loss due to human activities such as deforestation, urbanization, and agriculture. While habitat loss is a concern for biodiversity, it is a characteristic of areas under threat rather than a defining feature of a biodiversity hotspot itself.

3. **Lesser interspecific interaction**: In biodiversity hotspots, there is typically a rich variety of species, which leads to numerous interspecific interactions (interactions between different species). Therefore, lesser interspecific interaction does not characterize biodiversity hotspots; in fact, they usually have a higher level of interspecific interaction.

4. **High species richness**: Biodiversity hotspots are defined by their high species richness, meaning they have a large number of different species. This is another defining characteristic of biodiversity hotspots.

Based on this analysis, the character that is not related to biodiversity hotspots is **lesser interspecific interaction**.

### Final Answer:
The character that is not related to biodiversity hotspots is **lesser interspecific interaction**.
