Geographically separate ecosystems are often ecologically connected by flows of carbon and nutrients. Rivers receive nitrogen subsidies from the Pacific ocean in the form of migrating salmon; streams receive carbon from autumn-shed riparian leaves; riparian soils receive riverine sediments during flood events. Do human activities alter these connections? And if so, what are the ecological consequences? To answer these types of questions, Dr. Tiegs employs field-based experimental and observational approaches — usually in aquatic ecosystems — with the aim of better understanding how human activities impact aquatic ecosystems, and how undesired effects can be ameliorated through ecological restoration.
