acute toxicity of cadmium, lead, zinc, and their mixtures to stream-resident fish and invertebrates. | the authors conducted 150 tests of the acute toxicity of resident fish and invertebrates to cd, pb, and zn, separately and in mixtures, in waters from the south fork coeur d'alene river watershed, idaho, usa. field-collected shorthead sculpin (cottus confusus), westslope cutthroat trout (oncorhynchus clarkii lewisi), two mayflies (baetis tricaudatus and rhithrogena sp.), a stonefly (sweltsa sp.), a caddisfly (arctopsyche sp.), a snail (gyraulus sp.), and hatchery rainbow trout (oncorhynchus myki ... | 2012 | 22488500 |
mercury and selenium concentrations in biofilm, macroinvertebrates, and fish collected in the yankee fork of the salmon river, idaho, usa, and their potential effects on fish health. | the yankee fork is a large tributary of the salmon river located in central idaho, usa, with an extensive history of placer and dredge-mining activities. concentrations of selenium (se) and mercury (hg) in various aquatic trophic levels were measured in the yankee fork during 2001 and 2002. various measurements of fish health were also performed. sites included four on the mainstem of the yankee fork and two off-channel sites in partially reclaimed dredge pools used as rearing habitat for cultur ... | 2013 | 23080409 |
cottus schitsuumsh, a new species of sculpin (scorpaeniformes: cottidae) in the columbia river basin, idaho-montana, usa. | fishes of the genus cottus have long been taxonomically challenging because of morphological similarities among species and their tendency to hybridize, and a number of undescribed species may remain in this genus. we used a combination of genetic and morphological methods to delineate and describe cottus schitsuumsh, cedar sculpin, a new species, from the upper columbia river basin, idaho-montana, usa. although historically confused with the shorthead sculpin (c. confusus), the genetic distance ... | 2014 | 24869819 |
