My research focuses on understanding how the environment and other species affect wild plant populations. I study wild plants to comprehend the factors that affect how plant populations grow, timing of life events, and how traits change over time. Specifically, I am interested in how microorganisms affect plant populations, the role of maternal effects in trait evolution, and how mating patterns affect trait evolution and maintain diversity in natural populations.

To guide post-fire restoration efforts in grasslands in the Interior Northwest, I am investigating the efficacy of seed-zones via a reciprocal transplant experiment with Bluebunch wheatgrass (Psuedoroegneria spicata). This project is in collaboration with J. Brad St. Clair at the FS Pacific Northwest Research Station and members of the Rocky Mountain Research Station in Boise, ID including Nancy Shaw and Francis Kilkenny.

Examining the role of maternal effects on population adaptation on a forest herb, the American Bellflower(Campanula americana). The phenotype of an organism is due to genetic and environmental factors of the organism as well as maternal effects. Maternal effects are the contributions of the maternal environment and maternal phenotype on the offspring phenotype. Maternal effects are ubiquitous across plant taxa. In the American Bellflower, the initiation of flowering in the maternal plant affects the timing to germination in the offspring. The timing of germination in the American Bellflower determines the life history of an individual (i.e. annual or a biennial). This phenotypic plasticity allows a plant to respond to environmental heterogeneity and may allow for population adaptation to local environments. To investigate the role of maternal effects on population adaptation, Laura F. Galloway and I are 1) comparing the contributions of annuals and biennials to population growth rates among wild populations of American Bellflower along a range-wide transect, 2) determining the amount of variation in life history frequency among three common garden experiments over a latitudinal gradient, and 3) evaluating if selection on life history schedule acts on maternal traits, individual traits or both.
