The Donovan lab investigates plant evolutionary ecophysiology, with an emphasis on resource use and stress tolerance traits as they relate to plant performance. We study adaptations to growth limiting factors such as drought, nutrient limitations, and salinity. Our current study system primarily consists of wild and cultivated sunflowers that encompass a of wide range of plant ecological strategies and a powerful toolkit of ecological, genetic and genomic tools. In general, we want to know how individual plant traits affect plant fitness and distribution, and how adaptive traits evolve. To address these questions, we use a combination of ecological, ecophysiological, evolutionary genetic and genomic approaches. Prospective students with an interest in functional ecology, evolution, and genomics of plant traits are encouraged to apply.
