| changes in population, growth, and physiological indices of longnose dace (rhinichthys cataractae) in the red deer river, alberta, canada. | the red deer river, alberta, canada is a prairie river that is impacted by the point-source input of red deer's municipal wastewater effluent and non-point- source agricultural runoff. we used population, growth, and physiological performance end points in longnose dace (rhinichthys cataractae), an endemic and abundant minnow, to evaluate changes in fish health over a 220 km section of the red deer river. longnose dace immediately downstream of red deer had elevated catch per unit effort with la ... | 2008 | 18322724 |
| basin-wide impacts of compounds with estrogen-like activity on longnose dace (rhinichthys cataractae) in two prairie rivers of alberta, canada. | environmental compounds with estrogen- or antiestrogen-like activity can enter rivers from multiple sources, including municipal wastewater and agricultural runoff. we used longnose dace (rhinichthys cataractae) to investigate exposure to compounds with estrogen-like activity, which we measured in water at multiple sites in the oldman and bow rivers (ab, canada). we evaluated changes in vitellogenin mrna with quantitative reverse transcription-polymerase chain reaction, then compared vitellogeni ... | 2008 | 18380523 |
