Profile

Dr. O’Halloran’s research interests are in plant ecology and global environmental change. Specifically, she is interested in how land use and climate change affect herbaceous plant ecology. She examines how plants respond to environmental impacts at the species scale (e.g. loss of fitness or phenotypic plasticity) and at ecosystem scales (e.g. changes in gross primary productivity, relative diversity and abundance) in hopes of providing the science necessary for climate change conservation planning in South Carolina and beyond. Her current research on silvopasture understory has important implications for developing climate-smart solutions in using native vegetation in agroforestry practices.
