Employer: Joe Mrnak (email@example.com; he/him)
Description: I am seeking 2 motivated and independent undergraduate students to assist on two whole-lake manipulation experiments in northern Wisconsin. Broadly, this research/project attempts to serve as an extension of efforts to restore ecosystems and(or) manage fisheries using a food web and ecosystem context.
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 stakeholders, managers, and ecologists alike. Research will focus on characterizing the abundance, distribution, diets, and population dynamics of several fish species across multiple lakes. The work will primarily be composed of;
- ~70% of time (work will be conducted BOTH during the day and at night)
- Hydroacoustic fishery surveys
- Fish sampling (e.g., vertical/horizontal gillnets, fyke nets, boat electroshocking, etc.)
- Fish processing (length, weight, sex, diets, age structures, isotopes, etc.)
- Basic limnological and zooplankton sampling
- ~30% of time
- Sample processing (e.g., fish diets, age structures, zooplankton, isotopes, etc.)
- Data entry
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 this main project, there will be multiple opportunities to assist on and gain experience with other fisheries-based projects/groups (e.g., Wisconsin Department of Natural Resources-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 which is necessary 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.
