Definition
Glossary of "Biogeography (9th ed.)" by Cox et al. (2016)
- The rate or amount of change in species composition between local areas. Also known as turnover or differentiation diversity, beta diversity translates the number of species in local areas (alpha diversity) into the number of species in larger regions (gamma diversity). Low beta diversity means similar sets of species between patches or local areas, such that the gamma diversity will not be much higher than the alpha diversity.
