New publication: Lake Oahe, South Dakota distributional records

Apalone_spinifera_DRD-4106South Dakota amphibian and reptile distributional records are lacking, especially in the north-central counties in the state. To date, there have been few surveys of amphibians and reptiles from along Lake Oahe, a large reservoir on the Missouri River that was created in 1958 following construction of Oahe Dam. We conducted fieldwork on Lake Oahe in South Dakota in June 2017 and collected 13 new county records of six species of amphibians and reptiles: Woodhouse’s Toad (Anaxyrus woodhousii), Boreal Chorus Frog (Pseudacris maculata), Smooth Softshell (Apalone mutica), Spiny Softshell (Apalone spinifera), Painted Turtle (Chrysemys picta), and Plains Gartersnake (Thamnophis radix)Prior to these records, no vouchered specimens existed from these areas for these species and only anecdotal evidence or unverifiable reports of species occurrence existed. These vouchered specimens are important as they provide the first verifiable records of species occurrence in an area that is under-surveyed and depauperate of records.
