Total taxa richness

WebIf less than 10% of “marker” genes were seen in a sample, the abundance of the MSP was set to 0. Relative abundances at higher taxonomic ranks were computed as the sum of the MSP that belong to a given taxa. MSP richness was assessed as the number of MSP detected in a sample (that is, whose abundance is strictly positive). Functional Profiling Webwhere n is the total number of taxa; ni is the number of individuals of the i- taxon; - Margalef index. where S is the number of taxa; n is the size of community. The Margalef index reflects the species richness in a certain area, its calculation uses an absolute value (abundance), which makes it extremely sensitive to the sam-ple size.
