Which one of the following is not observed in biodiversity hotspots

Options

A. Less interspecific competition
B. Species richness
C. Endemism
D. Accelerated species loss.

Answer

**Step-by-Step Solution:**

1. **Understand the Concept of Biodiversity Hotspots:**
- A biodiversity hotspot is a region that is both rich in biodiversity and under threat from human activities. It is characterized by a high number of endemic species that are not found anywhere else in the world.

2. **Identify the Characteristics of Biodiversity Hotspots:**
- **Endemism:** This refers to species that are unique to a specific geographical area. Biodiversity hotspots typically have a high level of endemism.
- **Species Richness:** Biodiversity hotspots are known for having a large number of different species, which contributes to their overall biodiversity.
- **Accelerated Species Loss:** Due to habitat destruction and other anthropogenic factors, biodiversity hotspots often experience a higher rate of species extinction.
- **Interspecific Competition:** This is the competition between different species for resources. In biodiversity hotspots, the presence of many species can lead to increased competition.

3. **Analyze the Given Options:**
- **Less Interspecific Competition:** This suggests that there is minimal competition between species, which is not typical in biodiversity hotspots.
- **Species Richness:** This is a characteristic of biodiversity hotspots.
- **Endemism:** This is also a characteristic of biodiversity hotspots.
- **Accelerated Species Loss:** This is a consequence of the threats faced by biodiversity hotspots.

4. **Determine the Correct Answer:**
- The option that is not observed in biodiversity hotspots is **less interspecific competition**, as these areas typically have high competition due to the richness of species.

**Final Answer:**
Less interspecific competition is not observed in biodiversity hotspots.
