Detection of Cumberlandia monodonta male mitotype eDNA from an outdoor raceway tank during a spawning event Detection of Cumberlandia monodonta male mitotype eDNA from an outdoor raceway tank during a spawning event
Data describe the detection of Spectaclecase (Cumberlandia monodonta) female and male mitotype environmental DNA (eDNA) during a spawning event. Water samples (approximately 1L) were collected from an outdoor raceway tank containing C. monodonta from March to April 2021 and analyzed for the presence of sex-specific eDNA. Parameters described in this data release include water quality...
Detection of exogenous lake trout and endogenous spectaclecase DNA in the Big Piney River from an experimental release of lake trout slurry to study eDNA transport, September 2023 (ver.1.1, May 2025) Detection of exogenous lake trout and endogenous spectaclecase DNA in the Big Piney River from an experimental release of lake trout slurry to study eDNA transport, September 2023 (ver.1.1, May 2025)
This dataset includes eDNA concentrations of water samples from an experimental release of lake trout (Salvelinus namaycush) slurry used to analyze eDNA transport in the Big Piney River, Missouri. The spectaclecase (Cumberlandia monodonta) was also included as a target species due to the proximity of a known spectaclecase population at the slurry release site. The slurry, a frozen block...
