Table 1 Assessment of benthic macroinvertebrate communities in streams with crayfish (upper and lower Lindero, Medea, MLV), with newts (Arroyo, Cold Creek), or where there is coexistence (Trancas). Counts of species assigned to a functional group are also provided and include species counts for taxa that classify as intolerant, predator, scraper, shredder, burrower, climber, clinger, or swimmer (see [15, 41] for group definitions)
