Shannon richness
WebbTaxon richness is found by adding all the numbers of unique taxa in the sample. A higher taxon richness implies higher water quality because more species mean greater habitat diversity with different habitat requirements. The relative abundance, or evenness, of different taxa groups is measured by the biometric Shannon Diversity Index (Hʹ). Webb18 mars 2024 · While Simpson’s index cares more about relative abundances, the Shannon index cares more about species richness; or, put in another way, the importance of rare …
