The restoration of lakes impacted by human activities has been ongoing for decades, but biological recovery has often been slow and difficult to gauge due to a lack of pre-impact information. Dr. Rennies research group will examine the impacts of emerging contaminants on aquatic ecosystems, and develop paleo-eDNA methods for determining pre-impact communities in altered ecosystems, thus enhancing lake ecosystem recovery efforts through re-establishment of native species. This will be tested using a whole-lake re-establishment experiment. Additionally, research documenting fish behaviour and movement will be used to help inform more effective restoration strategies applied to recovering Great Lakes fish populations.

受人类活动影响的湖泊的恢复已经持续了几十年，但由于缺乏影响前的信息，生物恢复往往缓慢且难以衡量。 Rennies 博士的研究小组将研究新兴污染物对水生生态系统的影响，并开发古 eDNA 方法来确定受影响前生态系统中的群落，从而通过重建本地物种来加强湖泊生态系统的恢复工作。这将通过全湖重建实验进行测试。此外，记录鱼类行为和运动的研究将有助于制定更有效的恢复策略，以恢复五大湖鱼类种群。
