Mating System Evolution in Clarkia

The major goals of this work are to evaluate the factors that influence the evolution of self-fertilization within and among Clarkia species. In Clarkia, self-fertilization (autogamy) has evolved independently at least 12 times in the genus.  This provides the opportunity to examine multiple pairs of sister taxa — each comprised of one predominantly outcrossing and one predominantly self-fertilizing species or subspecies — when evaluating whether the same factors appear to promote the evolution of self-fertilization in each sister pair.  Recently, we have been interested in determining whether natural selection favors relatively short life cycles and rapid development under compressed growing seasons, resulting in correlated (indirect) selection on floral traits that also promote self-fertilization.

I am a plant ecophysiologist, interested in how plants deal with water stress through adaptation. This interest has taken me from my graduate work in the Colorado Rockies to the dry Sierra Nevada in California, to the high Andes. Throughout I've also been passionate about student-centered teaching, learning about the different forms this may take at each of the institutions that I've taught, and eventually leading me to my current position here at ECU.
