Etheostoma striatulum (Striated Darter) is an increasingly rare darter found in the middle-to-upper regions of the Duck River watershed in Tennessee. This rarity, coupled with a lack of collection and sampling, has put them in review for listing under the Endangered Species Act. Because of the Striated Darters' reclusive and cryptic behavior, conve...

Effective conservation of rare or imperiled species relies on efficient monitoring and accurate information regarding distribution, critical habitat locations, and occupancy. However, most imperiled species are inherently cryptic and difficult to capture due to patchy distributions and low population densities. To avoid these obstacles, environment...

Striated Darters (Etheostoma striatulum) are small, uncommon darters endemic to the Middle-to-Upper regions of the Duck River, Tennessee. Since their description, they have become increasingly rare within their range. Historically, Striated Darters occupied 16 tributaries of the Duck River; as of 2011, their known distribution has declined to nine...

Culverts are an effective means of controlling a river’s path beneath a road crossing, but undersized culverts alter the natural flow of the river, changing substrate and organic matter transport, which can negatively impact biota. This study explores the effects of five road stream crossings arrayed from the headwaters to mouth on a cool water, 4t...
