摘要: Best management practices (BMPs) are tools commonly used to mitigate negative impacts of agriculture on water quality; however, the relationship between BMPs and aquatic ecological function is unknown. Our research goal was determine association both stream ecosystem metabolism quality, abundance location four different in agricultural catchments. Dissolved oxygen measured over a two-week period mid-June estimate 13 headwater streams representing gradient BMP implementation Southern Ontario, Canada. Stepwise regression analyses were associate quality with metrics describing within each catchment. Studied exhibited rates comparable catchments from other regions. However, not associated either or quality. results suggest that studied improving mitigating during summer season. We propose seasonality catchment hydrology time lag effects past land use may be masking mitigation benefits conditions
