Environmental assessment in tropical streams by using abundance-biomass curves and W index in fish assemblages

Environmental assessment in tropical streams by using abundance-biomass curves and W index in fish assemblages

ABSTRACT We investigated the fish fauna response to different environmental conditions of urban (three) and rural (seven) streams through biomass/abundance curves and W index of environmental stress. Negative values of W indicate some level of stress, while positive values suggest environments with...
