Characterization of the Genetic Structure among Brook Trout in LeConte Creek, Tennessee

Beginning in the early 1900s, the original range and abundance of brook trout within Great Smoky Mountains National Park (GRSM) was drastically reduced due to landscape alterations resulting from increased logging and introduction of nonnative salmonid species. Consequently, brook trout populations retreated to the headwaters of most streams, resulting in geographic isolation due to waterfalls and eventual genetic differentiation of the fish inhabiting these streams. In an effort to reestablish LeConte Creek's extirpated brook trout population, GRSM fisheries managers collected fish from...
