Plant Physiological Ecology
Jennifer Boyd, Ph.D.
My research focuses on plant ecology with particular interest in the issues of species conservation and restoration, biological invasions, and plant responses to global change. Currently, my students and I are conducting several research projects. We are engaged in ongoing investigations of the growth and reproductive responses of rare and federally threatened large flower skullcap (Scutellaria montana) to disturbances including fire, forest thinning, and herbivory. We also are examining the light responses of hybrid chestnuts to determine how this variable may be inherited and how it could impact the success of local American chestnut (Castanea dentata) restoration efforts. Additionally, we recently began a large-scale multi-year survey of numerous invasive plant species in Tennessee Army National Guard training sites to help increase understanding of the associations between human disturbance and plant invasions and to assess the potential impact that non-native invasive plants may have on rare native plant species in these sites. We also are beginning a new research project designed to elucidate how abiotic factors might influence the reproductive success of locally rare white fringeless orchid (Platanthera integrilabia) toward aiding conservation of this species.
