Habitat tools for assessing instream-flow needs for fishes in the upper Roanoke River, Virginia
… in speciose, warmer-water streams. This included habitat and fish data sets for the upper Roanoke River (URR) in southwestern Virginia, collected during the warmer, low- f low seasons of 1989-1991. Physical data were collected in small, rectangular quadrats or crosssectional transacts, whereas …

Influences of watershed urban development on habitat heterogeneity and native fish diversity in a ridge and valley stream in Southeastern Tennessee
… Tennessee area. Stream water quality, habitat, and fish assemblages were sampled in May-June 2005 at seven sites (drainage areas <17 km2) in the Mountain Creek system (Tennessee River drainage). Watershed urban land use (predominantly residential) ranged from 1.62 % to 18.97 % and …

Effects of acid mine drainage on limnological conditions and fish assemblages in the Cumberland Plateau region of the North Chickamauga Creek System, Tennessee
… Relationships were examined among water quality, habitat, and fish assemblage variables. Stream pH averaged lower at AMD than reference sites (5.1 vs.6.3); pH values in the 3-5 range were observed at most of the AMD sites. Conductivity averaged higher at AMD than reference sites (123 .31 μSiem vs. …

The effect of depth-velocity correlations on aquatic physical habitat usability estimates
… permitted consideration of both physical habitat parameters (e.g., depth, velocity, substrate and temperature) and preferences for certain values of these parameters by selected organisms. This methodology was based on the PHABSIM (Physical HABitat SIMulation) computer system, which …

Effect of riparian land use on the biotic integrity of fish assemblages in Black Creek, Chattanooga, Tennessee
… (biotic integrity), water quality, instream habitat, and riparian land-use features at eight sites in Black Creek, May-June 2000. Water quality conditions (temperature, dissolved oxygen, pH, conductivity) were favorable for stream fishes, but some level of habitat degradation (bank erosion, …

Correspondence Between Aquatic Ecoregions and the Distribution of Fish Communities of Eastern Oklahoma
… to include major drainage basins and physical habitat attributes for some areas to adequately partition variance in key measures of biological integrity. Results from canonical correspondence analysis indicated that substrate size and habitat type were the primary physical habitat variables …

Distributions, Assemblage Structure, and Habitat Associations of Fishes in Two Streams of the Red Bird River Watershed, Kentucky
… in fish distribution, assemblage structure, and habitat associations were investigated in relation to the available macrohabitats (riffle, run, or pool) in Gilbert's Big Creek and Elisha Creek, 2nd and 3rd order streams, respectively, located within the Red Bird River watershed in southeastern …

A Survey of the Fishes and Habitat of the White River, South Dakota
… was the first comprehensive assessment of the fishes and habitat of the White River in South Dakota. The primary objectives were to 1) document the current species composition, relative abundance, distribution, and condition of fishes, and 2) quantify baseline physical habitat conditions. …

Seasonal Use of Missouri River Reservoir Deltas by Fishes
… piping, or dredging). However, novel aquatic habitats have developed as a result of sedimentation (e.g., reservoir deltas), and recent research suggests that these habitats are important to native fishes and support greater fish diversity than other reservoir habitats. As water resources …
