Calculation of macrozoobenthic ISS index (Basset et al. 2012, Barbone et al. 2012). Given as input a dataset with macrozoobenthic individual observations (individuals occurence and body size), produce as output a list of ISS values per site. Weight values for species richness have been setted according to Basset et al. 2012, they can be modified from the script (lines 24-33).
