Question

Consider the following pairs:

1. Alpha Diversity: Number of species in an ecosystem.
2. Beta DIversity : Amount of species change between ecosystems.
3. Gamma Diversity: Overall diversity within a large region

Which of the above is/are correctly matched?

• A. 1 and 3 only
• B. 1 and 2 only
• C. 2 and 3 only
• D. 1,2 and 3

Answer 1

The correct option is D 1,2 and 3

Alpha Diversity is measured by counting the number of taxa (usually species) within a particular area, community or ecosystem. Beta diversity is species diversity between two adjacent ecosystems and is obtaining by comparing the number of species unique to each of the ecosystem. Gamma diversity refers to the diversity of the habitats over the total landscape or geographical area.
