Description: We are seeking two motivated and independent undergraduate students to assist on two whole-lake experiments in northern Wisconsin.
Experiment 1: Invasive species are a global concern, particularly for aquatic ecosystems. In Wisconsin, invasive rainbow smelt (Osmerus mordax) negatively affect ecosystems that they colonize through competitive and predatory interactions with native species. Negative effects include shifting food webs, altering zooplankton communities, and the decline or extirpation of native cool- and cold-water fishes (e.g., yellow perch Perca flavescens, walleye Sander vitreus, cisco Coregonus artedi). Understanding and mitigating these effects and associated consequences are of primary interest to managers and ecologists alike. Research will focus on characterizing the abundance, distribution, diets, and population dynamics of several fish species across multiple lakes.
Experiment 2: Fish communities in northern lakes of Wisconsin are changing; coldwater species are declining as warm water species are expanding. Understanding the drivers and consequences of these fish community changes are of primary interest to agency and UW aquatic ecologists. Research focuses on characterizing the abundance/distribution of several fish species and their prey resources during a whole-lake experiment. For more information on this project, see walleye-sos.weebly.com.
For both projects, most of the work will be based in the field and may require long hours under sometimes adverse conditions. Fish sampling and habitat characterization will all be done via boat. Technicians will gain experience with several fish, limnological, and habitat sampling methods. Aside from these two projects, there will be multiple opportunities to assist and gain experience with other fisheries-based groups (e.g., WIDNR Escanaba Lake Research Station, UW-Stevens Point, NTL-LTER). Having students with different life experiences and backgrounds is critical to ensure the exchange of diverse ideas that is called for in training tomorrow’s scientists. Because we are actively working to increase diversity and inclusivity in our discipline, underrepresented groups are especially encouraged to apply.
