The U.S. Geological Survey is offering a cooperative agreement opportunity for partners affiliated with the Gulf Coast Cooperative Ecosystem Studies Unit (CESU) to conduct research on invasive hitchhikers associated with imported aquatic plants. The primary objective of this funding is to assess the role of plant structural complexity in facilitating the introduction of non-native species, which poses significant ecological and economic risks. This research is crucial for identifying potential vectors for invasive species, thereby aiding in the prevention of their introduction across the nation. The funding amount ranges from $0 to $150,000, with applications due by 5:00 p.m. ET on June 3, 2024. Interested applicants can reach out to Faith Graves at fgraves@usgs.gov for further information.
