The Michigan Chapter, North American Lake Management Society (McNALMS) and the Michigan Lakes and Streams Association (MLSA) recently announced the recipients of the 2021 Lake Research Student Grant Program. The two students selected were Ellen Foley, a master’s degree student at the Annis Water Resources Institute at Grand Valley State University and Scott Jackson, a doctoral candidate in the School for Environment and Sustainability at the University of Michigan. Ellen’s research titled Lake Responses to Elevated Levels of Chloride and Phosphorus will focus on the impacts of excess chloride and phosphorus on an urban lake located in Grand Rapids, MI. She will address if elevated chloride reduces lake turnover and increases anoxia and accumulation of reduced chemical substances in the lake bottom. She also will investigate internal phosphorus loading and subsequent phosphorus release from the sediments under anoxic conditions and the direct and indirect effects from high chloride concentrations. She hopes that the work offers insight into lakes experiencing both high chloride and phosphorus concentrations due to human inputs and helps strengthen citizen involvement in lake management decisions due to these inputs.
Scott’s research focuses on the Impacts of Climate Change on Gene Expression in Stocked Walleye Populations. Walleye’s distribution is limited by temperature, and studies have noted that these fish populations are declining in inland lakes, possibly due to climate change. Scott’s research will investigate how gene expression varies among walleye populations and link their differences in traits to walleye growth and survivorship. He will also measure acclimated responses to increases in temperature to determine impacts from both short and long-term exposure, the latter being associated with climate change. He hopes his research will benefit walleye stocking and management in inland lakes in Michigan. His approach will also provide methods for assessing other fish species’ response to climate change. McNALMS and MLSA congratulate these two students and look forward to their research results over the next year.
