Dr. McCarthy's research interests include: plant physiological ecology, global change, urban ecology, ecohydrology and elevated carbon dioxide (CO2) effects on forest ecosystems. Her research addresses how trees and forests respond to environmental changes, and, conversely how can they be managed to moderate environmental changes. This research draws on physiological and ecosystem ecology to explore how tree and forest-scale water and carbon cycle processes respond to global change factors, including changes in water availability, extreme weather events, elevated atmospheric CO2, and urbanization. Recent projects include measuring elevated CO2 effects on southern pine forest productivity, and quantifying tradeoffs between water use and carbon uptake in the urban forests of Los Angeles.
