What are alpha, beta, and gamma diversity?

Alpha, beta, and gamma diversity are different ways to measure biodiversity at various levels of an ecosystem.

Alpha Diversity

It refers to the diversity within a particular area or ecosystem. It is the number of species found in a specific habitat.

Beta Diversity

It compares the species diversity between two habitats. It shows the change in diversity from one environment to another.

Gamma Diversity

It is the overall diversity within a large region or landscape. It includes several ecosystems combined.

Together, these measures help scientists understand biodiversity at small, medium, and large scales.
