List of metrics calculated from values of taxonomic richness, diversity, abundance and biomass of benthic macroinvertebrate samples collected in Arroyo del Rincón.

Metrics Definition
Total taxonomic richness Total number of families + Oligochaeta + Hydracarina
EPT richness Total number of families belonging to Ephemeroptera (mayflies), Plecoptera (stoneflies) and Trichoptera (caddishflies)
Total abundance Total abundance (ind m−2) of macroinvertebrates
Abundance by families Abundance (ind m−2) of macroinvertebrates grouped by families
Dominance Percent of the most abundant taxon in relation to the total number of macroinvertebrates for each sample
Total biomass Total dry mass (mg m−2) of macroinvertebrates
Biomass by families Dry mass (mg m−2) of macroinvertebrates grouped by families
Margalef's diversity index D = (Total taxonomic richness − 1)/ln (Total abundance)
