Current Research

Forest ecosystem ecology, plant physiology, and ecohydrology. Examine the response of forest mass and energy cycling to biophysical drivers, including climate, topography, species composition, and management history. Quantify the components of the hydrologic and carbon budgets of southern Appalachian forests over the course of post-harvest stand development from 3 years to 200 years. Identify the magnitude of hydroclimate variability in the southern Appalachians and its effect on forest processes. Methodological approaches include leaf- and tissue-level physiology, efflux chambers, sap flux, eddy covariance, micrometeorology, and ecosystem modelling.

Research Interests

Forest ecosystem ecology, plant physiology, and ecohydrology

Past Research

Examining seasonal and interannual variability in the components of the hydrologic budget in a mature, Southeastern, deciduous forest. Quantifying factors affecting forest floor soil CO2 efflux, including species composition, site productivity, climatic forcing factors, nitrogen availability and fertilization, and elevated atmospheric CO2. Measuring and modeling components of the forest carbon cycle.

Why This Research is Important

Forests play an important role in the supply of clean water resources and the uptake and sequestration of carbon dioxide from the atmosphere. Our ability to understand forest biophysical processes will help us to predict the sensitivity of the hydrologic and carbon cycles are to climatic variability, disturbance, and management practices.

Warmer temperatures reduce forest productivity but not water use

Warmer temperatures are expected to lengthen the growing season for forests. Longer growing seasons may also increase forest water use and produ ...
