Welcome to the Lodge Lab at the University of Notre Dame! We combine basic and applied ecological research to contribute to conservation of the world’s fresh waters, with a particular emphasis on the causes, effects, and management of biological invasions. Through field and laboratory experiments as well as short- and long-term natural observations, we explore the complex interactions that occur among plants, invertebrates, fish, and other organisms and how aquatic communities change over time. Members of the Lodge Lab are developing new methods in ecological forecasting risk assessment to help guide policy and management actions aimed at preventing species introductions. We are also advancing novel technologies such as environmental DNA (eDNA) surveillance to improve the study and management of invaders, imperiled species, and other species of interest. Finally, we collaborate extensively across disciplines to link ecology with other fields such as economics to understand how changes in aquatic systems influence human use and perceptions.
