Electronic Theses and Dissertations
In the upper Ohio River watershed three species of small-bodied benthic fish the Bluebreast Darter, Etheostoma (Nothonotus) camurum (Cope), the Tippecanoe Darter, Etheostoma (Nothonotus) tippecanoe Jordan and Evermann, and the Spotted Darter, Etheostoma (Nothonotus) maculatum Kirtland previously existed in disjunct distributions due to poor water quality and habitat degradation. Signs of recovery indicated that these species were moving from areas of refugia into the deeper mainstem waters of the Allegheny and Ohio rivers and expanding their distributions. To provide information for the proper conservation management of these species this dissertation was divided into three stages: 1) distribution records were updated …
