Exploring nitrogen dynamics in the river network of a tropical watershed, Luquillo Mountains, Puerto Rico

Advisor: Dr. William McDowell

Richard Brereton

Description of Research


Since arriving at UNH as a PhD student in 2010, Rich has devoted himself to exploring the linkages between terrestrial and aquatic ecosystems in New Hampshire and Puerto Rico. His dissertation focuses on the nitrogen cycle in a tropical forest watershed in the Luquillo Mountains, particularly the hydrologic and biogeochemical controls on nitrogen export from streams and rivers. In Puerto Rico and elsewhere, the river network (i.e. the river, its tributaries, and its riparian zones) is a crucial point on the landscape where water transports nitrogen that plants and microbes can retain or transform. Nitrogen is an essential nutrient for all life but in excess can disrupt aquatic ecosystems and impair water quality. In his studies, Rich seeks to improve our understanding of the ecosystem processes that maintain a watershed’s delicate balance between nitrogen delivery and retention.
