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 ...

D) Alpha diversity captures both the organismal richness of a sample and the evenness of the organisms' abundance distribution. Here, alpha diversity is defined by the Shannon index , , where p i is the relative abundance of taxon i, although many other alpha diversity indices may be employed. E) Beta diversity represents the similarity (or ...

the conceptual difference between alpha and beta diversity is simple, but the choice of the indexes depends on the type of data you have and the aims of the research. I try to answer your questions.

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).

The data that can be extracted from a microbiome analysis take many forms (e.g., alpha diversity measures, PCs of the beta diversity PCoA, and the abundances of OTUs) that can be used as response variables in statistical models.

This module highlights the basics of generating and analyzing microbiome data. We will also discuss how computational scientists are revolutionizing the development of tools for analyzing large, complex biological data sets and show you some of the cool ways that we visualize data! ... Well what beta diversity is instead is this measure of the ...
