Influence of nature preserves on macroinvertebrate assemblages, water quality, and habitat quality along two urban streams
… as a threat to aquatic ecosystems, particularly stream ecosystems, is of growing concern due to the reliance of the condition of surrounding watersheds. Mitigation techniques, such as riparian re-planting and habitat enhancement, are often met with little improvement in stream biodiversity. The …

Fish and Habitat Relations at Multiple Spatial Scales in Cheyenne River Basin, South Dakota
… relations have not been extensively studied in streams of Northern Great Plains. I analyzed fish distributions and investigated relations of reach (e.g. channel shape, substrate) and landscape scale (e.g. catchment area) factors to small stream fish communities, in Cheyenne River Basin. Reach …

Effects of Impoundments on the Community Assemblage and Gene Flow of Stream Crayfishes
Dams and their impoundments block movement of stream organism and change stream physiochemical properties, which subsequently changes biological assemblages and creates barriers to gene flow. While changes in species assemblages and gene flow have been assessed for numerous impoundments and stream …

Biotic and abiotic responses to rural development and legacy agriculture by southern Appalachain streams
Streams are integrative systems spanning multiple spatial and temporal scales. Stream researchers, land-use managers, and policy decision makers must consider the downstream displacement of streams when approaching questions about stream ecosystems. The study of how anthropogenic land-use …
