Updated distribution, population genetic structure, and local occurrence patterns of Longnose Sucker (Catostomus catostomus) and Lake Chub (Couesius plumbeus) in the Black Hills of South Dakota.
Longnose Sucker (Catostomus catostomus) and Lake Chub (Couesius plumbeus) were once thought to exist throughout the Black Hills, South Dakota; however, recent surveys have documented dramatic declines. To inform future conservation, I provide: (1) updated regional and local distributions, (2) descri...
