Global change and urbanization expose plants to environmental stresses. Individual plants first respond to these stressful conditions at the molecular level, which then scale up to affect leaf-level physiology and whole plant growth. As each individual responds to new abiotic conditions, the genetic structure of the population will change. We study multiple aspects of an individual's phenotype - from gene regulation through fitness - to understand the mechanisms by which selection changed the genetic structure of a population.
