Response of brook char (Salvelinus fontinalis) and blacknose dace (Rhinichthys atratulus) to acidic episodes in three headwater streams within the Shenandoah National Park, Virginia
… with ANC. Brook char (Salvelinus fontinalis) and blacknose dace (Rhinichthys atratulus) were the only two species common to all watersheds. Both species used pools more than riffles (P<0.05). Brook char density in pools increased with ANC (P<0.05), ranging from 13.1 to 40.1 fish/100m². Blacknose …

Spring-fed streams in Virginia and assessment of livestock impacts
… averaged 0.47 individuals/m². Two species, blacknose dace (Rhinichthys atratulus) and sculpins (Cottus sp.) dominated most sites. Spring size and location factors more effectively predicted fish community structure than did instream habitat or riparian condition, indicating that composition …

Local effects of culverts on habitat features and fish assemblages in Blue Ridge streams
… < 0.10). Fish abundance (predominantly western blacknose dace Rhinichthys obtusus) was consistently higher downstream than upstream (P < 0.10), regardless of the culvert type. In addition, reaches downstream of artificial substrate culverts exhibited reduced species evenness compared to upstream …

Distribution and life history of the endangered James Spinymussel, pieurobema collina (bivalvia: unionidae)
… the common shiner (Notropis cornutus), rosyside dace (Clinostomus funduloides), bluehead chub (Nocomis leptocephalus), pumpkinseed (Lepomis gibbosus), and fantail darter (Etheostoma flabellare) in the South Fork Potts Creek. Eleven fish families were tested for suitability as fish hosts in the …

Short-term response of physical habitat and fish to the addition of large woody debris in two Appalachian Mountain streams
Large woody debris (LWD) was added to North Fork Stony Creek and North Prong Barbours Creek in southwest Virginia to inlprove fish habitat. The purposes of this study were to monitor stream channel response to the addition of LWD at a stream reach scale and at a local scale around individual logs, …
