the number of species since in its calculation they are counted twice, iv) that M-AMBI
acts as a “diversity-corrected AMBI”, and, thus, v) it suffers of the reduction of species
number along the transitional gradient. Finally, most benthic indices require the use of
the species level as the level of identification. According to the taxonomic sufficiency
principle it is possible to use the genus or the family level of identification, thus
reducing the cost of obtaining results in routine monitoring programs. Despite the
AMBI check-list contains the benthic taxa at the species level, the taxonomic
sufficiency principle is already present in the list since it also provides the ecological
status of most of the genus, families and also higher taxonomic levels (e.g. Hydroides
dianthus, Hydroides sp., Serpulidae; Tubificoides swirencoides, Tubificoides sp.,
Tubificidae, Oligochaeta; Heterotanais oerstedi, Heterotanais sp., Tanaidacea; etc.). A
genus or family level of identification for the WFD implementation in the benthic
compartment of Italian CTEs might be sufficient for evaluating the status of such water
bodies.
