Freshwater ecosystems are highly susceptible to anthropogenic changes associated with human activities, but these impacts are often manifested across multiple species that interact between the aquatic-terrestrial interface. Our research focuses on changes in trophic associations and food web dynamics to understand how anthropogenic impacts relate to changes in ecosystem function and services.
