One of my favorite areas of investigation involves the study of Galápagos Islands angiosperms (flowering plants) and their pollinators. Most recently, this work has focused on a study of nocturnal pollinators. Research on the pollen-ovule ratios and pollen size of selected Galápagos plants is also being conducted.
I also have students involved in research dealing with the systematics of Galápagos angiosperms. Currently, we are conducting a taxonomic revision of the endemic members of Cordia (Boraginaceae) in the Galápagos. These endemics are an example of the classic island phenomenon known as adaptive radiation.
Another project in which I'm currently involved is a survey of the vascular plants of Rockingham County. During the summer of 2002, one of my research students and I began updating the list of plants indigenous to this county. The last time Rockingham was studied in detail was when I conducted a similar survey for my M.S. degree here at JMU. The information gathered will assure that our records are up to date. Interested students may contribute to this field of study by conducting similar studies on other counties in the Shenandoah Valley of Virginia (Augusta, Clarke, Frederick, Page, Shenandoah, and Warren). Cataloging the plants in this historic valley is the ultimate aim. Such information will also be useful for the Flora of Virginia Project, which is now in the works.
