An Interpolation Method For Stream Habitat Assessments With Reference To The Crystal Darter, Kenneth Richard Sheehan

Graduate Theses, Dissertations, and Problem Reports

Crystallaria asprella spp. (Elk River crystal darter) is documented only in Elk River, West Virginia. Little life history detail is known about this lotic, benthic-dependent species. Previous studies have led to a very basic understanding of the use of depth, flow and substrate of the crystal darter (Crystallaria asprella), and less is known about the Elk River crystal darter. Due to substrate-specificity in crystal darters (which reportedly bury in sand), a study concerning benthic stream habitat modeling was undertaken. Substrate and depth modeling using >5% of an area sampled at a resolution of 0.093 m2 square spatial data in a …

Mankweng, Limpopo, South Africa has experienced a large population growth since its inception in the late 1950s. The impacts of land use changes in the area are far reaching and have a wide range of influences.
