margalef

taxon

count


Margalef Index of Diversity is given by
 $$D = \frac{S-1}{\ln(N)}$$


Tool for analysing benthos data. It estimates several quality
indices like the total abundance of species, species richness,
Margalef's d, AZTI Marine Biotic Index (AMBI), and the BEQI-2 index.
Furthermore, additional (optional) features are provided that enhance data
preprocessing: (1) genus to species conversion, i.e.,taxa counts at the
taxonomic genus level can optionally be converted to the species level and
(2) pooling: small samples are combined to bigger samples with a
standardized size to (a) meet the data requirements of the AMBI,
(b) generate comparable species richness values and
(c) give a higher benthos signal to noise ratio.
