AMBI_sal

Used by <code>DKI2()</code>, adjusting the <code>AMBI</code> index to
account for decreasing species diversity with
decreasing salinity.

Calculate AZTI’s Marine Biotic Index - AMBI. The included list of
benthic fauna species according to their sensitivity
to pollution. Matching species in sample data to the list allows the
calculation of fractions of individuals in the different sensitivity
categories and thereafter the AMBI index. The Shannon Diversity Index H'
and the Danish benthic fauna quality index DKI (Dansk Kvalitetsindeks) can
also be calculated, as well as the multivariate M-AMBI index.
