BBI: Benthic Biotic Indices Calculation from Composition Data
Set of functions to calculate Benthic Biotic Indices from
composition data, obtained whether from morphotaxonomic inventories or
sequencing data. Based on reference ecological weights publicly available for
a set of commonly used marine biotic indices, such as AMBI (A Marine Biotic Index, Borja et al., 2000) <doi:10.1016/S0025-326X(00)00061-8>
NSI (Norwegian Sensitivity Index) and ISI (Indicator Species Index) (Rygg 2013, <ISBN:978-82-577-6210-0>). It provides the ecological quality status of the samples based on each BBI as well as the normalized Ecological Quality Ratio.
