My lab addresses questions related to the evolution, ecology, development and conservation of flowering plants and their communities. One focus of my research explores the conditions that favor or maintain both outcross and self-pollination within populations and species (mixed mating) including the pollination environment and inbreeding depression. We are testing the long-standing idea that selfing is an evolutionary dead-end using the genus Collinsia, an excellent model system. For the past two years (2005-07) I co-led a working group at National Evolution Synthesis Center (NESCent) on the Paradox of Mixed Mating in Flowering Plants. Related to the evolution of selfing, I investigate the development of male and female phases within a flower, which influences the timing of selfing within a flower and exploring the role of genes in the floral symmetry gene network in gender phase expression development. My second major focus is the role of herbivory on population and community dynamics of forest understory herbaceous species. This research addresses the dynamics of palatable vs. unpalatable species and the role of white-tailed deer and invasive species in the destabilization of mutualisms, populations, and communities. I also have long-standing, long-term research projects on the evolution of seed dormancy.
