In the Urban Ecology Lab, we study how global environmental change alters terrestrial ecosystems embedded within urban, suburban, and exurban landscapes. As the global population continues to rise and become more urbanized, the necessity for greenspaces within cities and towns to provide ecosystem services expands. Across developed landscapes, human activities alter species composition and biogeochemical cycles. In the Trammell lab, we use a variety of lab, field, and modeling techniques to understand controls on species composition and diversity and to assess changes in plant-soil carbon and nitrogen cycling in urban ecosystems. Our research spans residential lawns and small forests, from management impacts on lawn C and N cycling to non-native plant invasion and sea level rise impacts on small forests.
