Evaluating the impacts of urbanization and stormwater management practices on stream response
… Ephemeroptera, Plecoptera, and Trichoptera (EPT) richness, EPT percent richness, and a benthic index of biotic integrity (B-IBI) for the eight North Carolina Piedmont watersheds were found to be linearly related to the T0.5 hydrologic metric computed for 1-, 2-, 5-, 10-, and 20-year time …

Relative importance of Conservation Reserve Programs to mayfly, stonefly, and caddisfly species richness in the Kaskaskia River basin of Illinois
… (stoneflies), and Trichoptera (caddisflies) (EPT) in the Kaskaskia River basin, a heavily impacted, predominantly agricultural watershed in central and southern Illinois. A total of 10,522 EPT specimens were examined from 84 sites across the basin during May and June of 2013-2015. Seventy-six …

An Ecotoxicological Evaluation of Active Coal Mining, Sedimentation and Acid Mine Drainage in Three Tributaries of the Leading Creek Watershed, Meigs County, Ohio
… using physical (water chemistry and sediment depth analyses), toxicological (acute water column, chronic sediment and 35-day in situ toxicity tests) and ecological (benthic macroinvertebrate community sampling) parameters. Persistent acute toxicity (mean 48-hr LC50 of 30.3% to C. dubia) due to …

Ecotoxicological Evaluation of Hollow Fill Drainages in Low Order Streams in the Appalachian Mountains of Virginia and West Virginia
… no significant alteration in total taxa or EPT richness downstream of the ponds. Yet, collector filterer populations, including benthic macroinvertebrates and <i>in situ</i> Asian clams, were enhanced directly downstream of the ponds due to organic enrichment originating from the ponds. A …

Effects of Stream Crossings on Macroinvertebrate Assemblages of the Upper Current River, Ozark National Scenic Riverways, Missouri
… taxa, I calculated four metrics (taxa richness, Shannon's index, EPT, biotic index) combined into the Stream Condition Index and assessed effects of stream crossings with a two-way nested ANOVA for each season. All metrics showed strong differences among sites but inconsistent effects …
