EPA-ORD work on genomic surveillance tools

Impact/Purpose:
This workgroup exists for the purpose of informing Great Lakes States in their efforts to conduct aquatic invasive species monitoring. Presenting on EPA advances in genomic surveillance methods and supporting biological inventories to this workgroup thus helps transfer knowledge and tools developed by EPA/ORD to stakeholders.
Description:
This presentation serves as a briefing to the IEDRR workgroup on several aspects of EPA research. The topics covered are 1) The efficacy of surveying fishes via metabarcoding of eDNA samples vs. traditional net-based fish surveys (2016 and 2018 data); 2) The outcome of a 2017 survey for Dreissena mussels, and 3) efforts to improve the information basis for invertebrate surveys. These are all aspects of the invasive species research being conducted by staff from the EPA/ORD Duluth and Cincinnati laboratories. Topic 1 speaks of work in the St. Louis River estuary (western end of Lake Superior) and shows that eDNA surveys are generally an effective alternative to traditional fish survey. Topic 2 speaks of work in the Apostle Islands (western Lake Superior) and demonstrates the resource intensive nature of early detection. Topic 3 speaks of efforts by ORD to build a Great-Lakes wide species inventory as well as efforts by GLNPO (with ORD support) to address gaps in genetic barcodes for non-vertebrate species in the Great Lakes.
