WebbWeb page has moved to a new location: → Alpha and beta diversity. www.metagenomics.wiki WebbAlpha diversity is the diversity within a particular area or ecosystem, usually expressed by the number of species (i.e., species richness) in that ecosystem. Alpha diversity estimates are calculated from a series of rarefaction analyses and hence dependent on sampling depth. The Alpha diversity tool takes abundance tables as input.
