WebThe richness (Chao 1) and diversity (Shannon) index values were used to determine soil microbial alpha-diversity. The Pearson’s correlation analysis [ 56 ] was employed to study the associations between the soil microbial alpha-diversity and environmental variables as well as the relative abundance of dominant bacterial and fungal taxa.

WebBrief outlines of the two types of diversity indices of biodiversity are discussed in this article. The two types are: (1) Dominance Indices, and (2) Information-Statistic Indices. 1.
