My research program in plant physiological ecology is largely focused on: 1) developing a physiologically-based understanding of evolutionary adaptation, and 2) determining the patterns and mechanisms involved in physiological acclimation to environmental change and abiotic stress. I am also interested in developing a global perspective of genetic variation in physiological acclimation, or the way in which adaptation influences acclimation.
I am particularly interested in the following fundamental questions: Does physiological acclimation improve plant growth and fitness in variable or stressful environments? Are there predictable patterns of genetic variation in physiological acclimation across plant function types, species, and populations? If so, is variation in acclimation associated with patterns of adaptation (i.e. environmental selection) within and across species or species/population biogeography (e.g. species distribution)?
Ultimately, I hope that by understanding the patterns, mechanisms, and fitness implications of genetic variation in physiological acclimation we can improve predictions of plant species responses to environmental change, and C and H2O fluxes over space and time. To date, my study systems have included broadleaved trees (Eucalyptus spp.), conifers (Pinus), and perennial C4 grasses (Panicum spp).
Lastly, I have long-standing interests in understanding how genetic and environmental factors combine to influence forest ecosystem function, as well as forest responses to disturbance and threats. At UNF, I hope to explore these and many other important questions relevant to coastal ecosystems.
