Rate of replacement of species along a gradient of habitats/communities is called

Options

A. `alpha`-diversity
B. `beta`-diversity
C. `gamma`-diversity
D. `omega`-diversity

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the rate of replacement of species along a gradient of habitats or communities.

2. **Identifying the Options**: The options provided are:
- Alpha diversity
- Beta diversity
- Gamma diversity

3. **Defining Alpha Diversity**: Alpha diversity refers to the local species pool within a specific habitat or community. It measures the diversity of species in a particular area.

4. **Defining Beta Diversity**: Beta diversity measures the change in species composition between different habitats or communities. It specifically looks at the rate of replacement of species as you move from one habitat to another.

5. **Defining Gamma Diversity**: Gamma diversity refers to the total species diversity across a larger region that encompasses multiple habitats or communities. It combines the alpha and beta diversities.

6. **Identifying the Correct Answer**: Since the question specifically asks for the rate of replacement of species along a gradient of habitats or communities, the correct answer is **Beta Diversity**.

7. **Conclusion**: Therefore, the rate of replacement of species along a gradient of habitats or communities is called **Beta Diversity**.
