| 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 |
| modelling competition and hybridization between native cutthroat trout and nonnative rainbow and hybrid trout. | native salmonid fish have been displaced worldwide by nonnatives through hybridization, competition, and predation, but the dynamics of these factors are poorly understood. we apply stochastic lotka-volterra models to the displacement of cutthroat trout by rainbow/hybrid trout in the snake river, idaho, usa. cutthroat trout are susceptible to hybridization in the river but are reproductively isolated in tributaries via removal of migratory rainbow/hybrid spawners at weirs. based on information-t ... | 2010 | 22876984 |
