Shannon index microbiome

Webb2 nov. 2024 · The Shannon diversity index (a.k.a. the Shannon–Wiener diversity index) is a popular metric used in ecology. It's based on Claude Shannon's formula for entropy and estimates species diversity. The index takes into account the number of species living in a habitat (richness) and their relative abundance (evenness). WebbThe Abundance-based coverage estimator (ACE) and the Shannon index were calculated to evaluate alpha diversity. ... Microbiome data filtered for genomes with a minimum of 0.05% relative abundance in ≥2 samples. Microbiome data are centered log-ratio-transformed relative abundance. Metabolomics data are log-transformed auto-scaled values.
