range expansions, and for helping to locate rare and endangered native species. The Center is working on the development and application of these methods for detecting DNA of aquatic species in the water. We have also developed genetic markers for several native species such as the American eel, dwarf wedgemussel, American shad, alewife, and blueback herring. And we have developed novel techniques for identifying multiple species in a single water sample to assess the community while also detecting invasive species. Our work is helping state and federal agencies with their early monitoring and detection of aquatic invasive species such as blue catfish, round goby and northern snakehead.
