Evenness alpha diversity
Web1 day ago · Alpha diversity measures included Shannon diversity index, inverse Simpson diversity index, observed richness, and Pielou’s evenness. Alpha diversity was compared between experimental groups using Wilcoxon signed-rank test (analysis by collection method) or Wilcoxon rank-sum tests (analysis by sex). WebSpecies diversity is the number of different species that are represented in a given community (a dataset). The effective number of species refers to the number of equally abundant species needed to obtain the same mean proportional species abundance as that observed in the dataset of interest (where all species may not be equally abundant). …

WebWe will perform some basic exploratory analyses, examining the taxonomic composition of our samples, and visualizing the dissimilarity between our samples in a low-dimensional space using ordinations. Lastly, we will estimate the alpha diversity (richness and evenness) of our samples. Libraries WebThe diversity of order zero ( alpha = 0) is completely insensitive to species frequencies and is better known as species richness. Increasing the order diminishes the relative weights of rare species in the resulting index (Jost 2006, Legendre & Legendre 1998). ... The evenness of a community can be represented by Pielou's evenness index, which ...
