Freshwater Ecology and Fisheries

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出现的污染物对水生生态系统的影响，并开发古edna方法来确定改变的生态系统中受影响前的群落，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用于帮助制定更有效的恢复策略，以恢复五大湖的鱼类种群。

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.
