evaluation of ecologically relevant bioassays for a lotic system impacted by a coal-mine effluent, using isonychia. | many studies investigating the ecotoxicological impacts of industrial effluents on fresh-water biota utilize standardized test species such as the daphnids, ceriodaphnia dubia, daphnia magna, and the fathead minnow, pimephales promelas. such species may not be the most predictive or ecologically relevant gauges of the responses of instream benthic macroinvertebrates to certain stressors, such as total dissolved solids. an indigenous species approach should be adopted, using a sensitive benthic c ... | 2004 | 15195819 |
