Pollination ecology and floral biology
My current research projects center on the ecology and floral biology of the annual wildflowers Clarkia unguiculata and C. tembloriensis. The research falls into two general categories. The first examines the biology of a naturally occuring homeotic mutant (cp) of floral form in C. tembloriensis. In this mutant, normal petals are replaced with organs resembling sepals. My previous investigations have described aspects of the genetics, anatomy and development of the cp mutant. Future studies will investigate the ecological and evolutionary significance of the cp mutation in Clarkia. My second area of research explores factors affecting pollen performance in C. unguiculata and C. tembloriensis. I have examined the effects that breeding system, pollen deposition patterns, floral anatomy, and nutritional status can have on pollen performance in Clarkia. I plan future studies to gain a more complete understanding of the pollination ecology of Clarkia.
