Fish and Invertebrate Flow‐Biology Relationships to Support the Determination of Ecological Flows for North Carolina

摘要: A method was developed to characterize fish and invertebrate responses flow alteration in the state of North Carolina. This involved using 80th percentile linear quantile regressions relate six metrics diversity riffle-run benthic Ephemeroptera, Plecoptera, Trichoptera (EPT) richness. All twelve flow-biology relationships were found be significant, with both benthos showing negative ecodeficits reductions flow. The richness reduced flows consistent generally greater than that diversity. However, guild showed greatest response summer ecodeficits. directional consistency differential seasonal sensitivities invertebrates highlight need consider seasonality when managing flows. In addition, all linear, therefore do not provide clear thresholds support ecological determinations prescriptions prevent degradation communities Carolina rivers streams. setting based on magnitude change biological condition is acceptable society explored.
