Julia Cherry received a Ph.D. in Biological Sciences from the University of Alabama in 2005 and completed her postdoctoral research at the United States Geological Survey. She was appointed Assistant Professor at the University of Alabama in 2006. Dr. Cherry has a joint appointment with the Department of Biological Sciences and New College.

Research Interests

My research is aimed at understanding the various mechanisms influencing the structure and function of wetland ecosystems. The majority of my research is focused on responses of Gulf of Mexico tidal marshes to global environmental changes, including climate change and nutrient enrichment. I also work closer to campus in freshwater wetlands near Tuscaloosa.

Global Change Effects on Tidal Wetlands: 

The goal of our coastal wetland research program is to understand the ways in which tidal marshes can keep pace with sea-level rise through biological feedbacks to marsh surface elevation. In particular, we examine how simultaneously changing external forcing factors, such as elevated CO2, sea-level rise, nutrient enrichment, storm sedimentation, or fire, affect marsh processes that regulate organic matter accumulation, vertical accretion, or the capacity for upslope migration. We combine greenhouse and field studies to (1) identify biophysical processes regulating marsh surface elevations; (2) examine impacts of disturbance or restoration on marsh structure and function; and (3) help develop models that inform adaptive management and restoration strategies.

Population and Community Dynamics in Temperate Freshwater Wetlands:

To a lesser extent, we conduct research in local freshwater wetlands with the goal of understanding how plant communities respond to changes in their environment, interact with each other, and influence ecosystem processes. This work includes investigation of plant responses to invertebrate grazing, to competition with other plant species, and to water level fluctuations. We have examined how changes in community composition and liter quality influence patterns of nutrient or material export from beaver-formed wetlands embedded within larger stream networks.
