Environmental DNA qPCR detection results and covariates from Idaho, Missouri, Montana, and New York rivers sampled in 2023

This dataset contains quantitative results from, and covariate attributes of, environmental DNA water samples collected across multiple rivers in 2023. Samples were analyzed for eDNA of round goby in the Hudson River (NY), westslope cutthroat trout (Oncorhynchus clarkii lewisi) in Cherry Creek (MT), lake trout (Salvelinus namaycush) and Spectaclecase mussels (Cumberlandia monodonta) in Big Piney River (MO), and rainbow trout (O. mykiss) and Western Pearlshell (Margaritifera falcata) in Loggers Creek (ID).
