The terms alpha, beta, and gamma diversity were all introduced by R. H. Whittaker to describe the spatial component of biodiversity. Imagine that you have a landscape containing of a number of separate sites and habitats. Alpha diversity is just the diversity of each site (local species pool).

Gamma diversity is the total diversity of a landscape and is a combination of both alpha and beta diversity. In the image below, assume the different colors represent different species of fish. The alpha diversity of Site A is 3 because there are three different species at Site A.

en.wikipedia.org/wiki/Gamma_diversity

In ecology, gamma diversity (γ-diversity) is the total species diversity in a landscape. The term was introduced by R. H. Whittaker together with the terms alpha diversity (α-diversity) and beta diversity (β-diversity). Whittaker's idea was that the total species diversity in a landscape (γ) is determined by two different things, the mean species diversity in sites or habitats at a more ...

en.wikipedia.org/wiki/Alpha_diversity

In ecology, alpha diversity (α-diversity) is the mean species diversity in sites or habitats at a local scale. The term was introduced by R. H. Whittaker together with the terms beta diversity (β-diversity) and gamma diversity (γ-diversity). Whittaker's idea was that the total species diversity in a landscape (gamma diversity) is determined by two different things, the mean species ...

Alpha, Beta,\n and Gamma Diversity \n Alpha\n\tdiversity refers to the diversity within a particular\n\tarea or ecosystem, and is usually expressed by the number of\n\tspecies ( i.e. , species\n\trichness ) in that ecosystem.

Introduction. Half a century ago, Whittaker first defined species diversity from three different perspectives: alpha (α) diversity, beta (β) diversity, and gamma (γ) diversity .Alpha and γ diversity are grouped as inventory diversity , sharing the same characteristics and differentiated only by scale.Beta diversity is defined as the difference in species composition between communities and ...

Whittaker (1972) described three terms for measuring biodiversity over spatial scales: alpha, beta, and gamma diversity. Alpha diversity refers to the diversity within a particular area or ecosystem, and is usually expressed by the number of species (i.e., species richness) in that ecosystem.For example, if we are monitoring the effect that British farming practices have on the diversity of ...

In the example below, the greatest Beta Diversity is observed between Site A and C with 10 species that differ between them and only 2 species in common. Gamma Diversity = landscape diversity or diversity of habitats within a landscape or region. In this example, the gamma diversity is 3 habitats with 12 species total diversity.

Alpha diversity is subtly different from the other two measurements, known as beta and gamma. Alpha diversity deals with species in a single area, while beta diversity is a measure of the difference in diversity between ecosystems in a given area.
