How to interpret beta diversity
WebBeta diversity is another name for sample dissimilarity. It quantifies differences in the overall taxonomic composition between two samples. Common indices include Bray … Web& Mohler 1983). The second is that beta diversity represents the number of communities present. Since communities in nature are seldom discrete and countable, a given value, say c, of beta diversity in this interpretation is actually equivalent to the amount of heterogeneity that would obtain if there were exactly c distinct communities present.
