Demonstrating the presence or absence of species with eDNA

With ORVIdetect we are able to measure invasive exotics in water and silt samples taken from surface waters. Species such as the American Red Crayfish (Procambarus clarkii), the Muskrat (Ondatra zibethicus), the American Bull Frog (Rana catesbeiana) and the Topmouth gudgeon (Pseudorasbora parva) are detectable with eDNA. With eDNA methods …
