We developed and evaluated three qPCR assays for detecting environmental DNA from northern pike (Esox lucius). The assays target the cytochrome oxidase 1 (EluCOI), control region (EluCR), and cytochrome b (EluCytB) genes of the mitochondrial DNA. Target specificity, assessed using the fluorescence signal (at 45 cycles) to noise (at 1 cycle) ratio (S/N),(More)

Error-tolerant likelihood-based match calling presents a promising technique to accurately identify recapture events in genetic mark-recapture studies by combining probabilities of latent genotypes and probabilities of observed genotypes, which may contain genotyping errors. Combined with clustering algorithms to group samples into sets of recaptures based(More)
The endangered fountain darter Etheostoma fonticola is found only in the Comal and San Marcos rivers in the Guadalupe River basin in central Texas, USA. Comal River fountain darters were believed to be extirpated following a severe drought in the 1950s and were reintroduced in the early 1970s using 457 darters from the San Marcos River. In this study we(More)
