Structural responses of benthic macroinvertebrate communities from different stream orders to zinc
Abstract It is well established that benthic invertebrate community structure and function shift in a predictable fashion along longitudinal stream gradients as a result of variation in environmental conditions. Our research is concerned with experimentally testing whether this shift in community st...
