Which scientist proposed `alpha, beta` and `gamma` types species diversity

Options

A. Bentham and Huxley
B. Linnaeus
C. Whittaker
D. Eichler

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which scientist proposed the concepts of alpha, beta, and gamma types of species diversity in biodiversity.

2. **Identifying the Options**: The options provided are:
- A) Random and Hypothesis
- B) Ranius
- C) Reticular
- D) Equivalent

3. **Defining Alpha, Beta, and Gamma Diversity**:
- **Alpha Diversity**: Refers to the diversity of species within a particular area or ecosystem (local diversity).
- **Beta Diversity**: Refers to the change in species composition between different ecosystems or areas (turnover diversity).
- **Gamma Diversity**: Refers to the total species diversity across multiple ecosystems (regional diversity).

4. **Finding the Scientist**: The term "alpha diversity" was coined by the scientist R. H. Whittaker (Robert Cook Whittaker). He is known for his work on these types of diversity.

5. **Conclusion**: Based on the information, the scientist who proposed the concepts of alpha, beta, and gamma diversity is R. H. Whittaker. Therefore, the correct answer is not among the options given, but it is clear from the explanation that Whittaker is the relevant scientist.

6. **Final Answer**: The correct answer is R. H. Whittaker.
