19. Invasive Species Research and Communication Invasive species are a leading threat to native species and biodiversity, are an important driver of global ecological and evolutionary change, restructure food webs, and have caused significant economic damage to aquatic ecosystems. This session welcomes presentations reflecting a broad array of aquatic invasive species research in aquatic ecosystems, including ecological, economic, social science, communications, education, and evaluation research. Presentations about efforts to connect invasive species research to lay audiences (community science, education, etc.) are also welcome. Chaired by: Rochelle Sturtevant, El Lower

Are you a #GreatLakes #InvasiveSpecies researcher who wants to contribute to #AIS knowedge in the region? The #GLANSIS team requests your expertise for our first Grand Review of species profiles and risk assessments! Please reach out to Program Manager Rochelle Sturtevant, and share w/ your network!
Who: Professional level experts in the field are invited to participate in a review process for the Great Lakes Aquatic Nonindigenous Species Information System. What: The GLANSIS database provides information on exclusively aquatic nonindigenous species in the entire Laurentian Great Lakes region regardless of national or state-level boundaries. GLANSIS does not provide data on reptiles, amphibians, or waterfowl, since they spend substantial portions of their lives outside the water. The database also includes facultative wetland plants in its target species. GLANSIS formally requests your participation in an external review process that will assist in the publishing of risk and impact assessments as well as species profiles that appear in the GLANSIS database. Each assessment and profile document follows a rigorous review process requiring two external reviews by subject matter experts before being published on the GLANSIS website. Materials provided for review will have already gone through the required NOAA internal review. When & Where: February 14-March 6 (independent review) Thursday Mar 6, 2025 (virtual event) How: The GLANSIS team will provide you with your assigned assessments and profiles by February 14. We will need all reviews completed by March 5. On the day of the virtual event, each species will be presented for discussion and approval. You are welcome to attend the entire event if you wish, but are required only to attend the segments of the agenda relevant to your assigned species. In addition to the assigned reviewers (2 per species), the virtual event will be open to any researcher, manager, or student who wishes to contribute data or information about these species. Honorarium: Your time and expertise are valuable. We can provide each reviewer with a $200 honorarium for your time and expertise in this review process. RSVP asap to Rochelle Sturtevant (rochelle.sturtevant@noaa.gov), GLANSIS Program Manager, Michigan Sea Grant.
