Question

Diversity of habitat over the total landscape is called :

• A. Beta diversity
• B. Gama diveristy
• C. Landscape diversity
• D. Ecosystem diversity

Answer 1

The correct option is B Gama diveristy

Gamma diversity is the diversity of habitat over a total landscape.

Gamma diversity ($\gamma$ - diversity) is the total species diversity in a landscape. The term was introduced by R. H. Whittaker together with the terms alpha diversity ($\alpha$ - diversity) and beta diversity ($\beta$ - diversity). Whittaker's idea was that the total species diversity in a landscape \((\gamma)\) is determined by two different things, the mean species diversity in sites or habitats at a more local scale $\left(\alpha \right)$ and the differentiation among those habitats $\left(\beta \right)$ According to this reasoning, alpha diversity and beta diversity constitute independent components of gamma diversity.
