Which of the following is the comparison of diversity between ecosystems, usually measured as the amount of species change between the ecosystems?
- Alpha diversity
- Beta diversity
- Gamma diversity
- None of the above
Hint:
Beta diversity
The correct answer is: Beta diversity
Beta diversity describes the species diversity between two communities or ecosystems.
Beta diversity, the spatial turnover or change in the identities of species, is a measure of the difference in species composition either between two or more local assemblages or between local and regional assemblages.
