Title: Characterization of Stream Fish Assemblages and Land Use Associations within a Southern Ohio National Forest. Abstract approved:

Seasonally, in 1998 and 1999, I examined spatial and temporal variation in fish assemblages of agricultural, forested, and acid mine drainage tributaries within the Wayne National Forest (WNF) in southern Ohio. Land use and natural disturbance explained patterns in stream fish assemblages. Creek chub and green sunfish were present in all land use types. Generally, with the exception of creek chub and green sunfish, species most abundant in one land use type occurred infrequently in the other land use types sampled. For example, redbelly dace and blacknose dace dominated forested assemblages but rarely occurred in mining or agricultural assemblages. Redacted for Privacy Redacted for Privacy Agricultural sites consisted of higher order streams, located at lower elevations with reduced canopy cover. Forested sites included intermittent streams associated with higher elevation, low stream order, and high canopy cover. Acidic conditions characterized mining sites, which otherwise remained physically simila
