RESEARCH INTERESTS

My research interests generally fall under the umbrella of reproductive ecology and population genetics of rare plant species. Much of my work has focused on nonrandom reproductive success, particularly differences in male fitness, in rare taxa. More recently I have become interested in outbreeding depression, which we are currently studying in Lobelia cardinalis and Lobelia syphilitica. Another line of research focuses on patterns of genetic variation, methods for estimating genetic variation (such as morphological differences including developmental instabilities, RAPDs, ISSRs, and heritability studies) and their relationship to restoration. I am also interested in genetic change in ex situ (off site) living collections, such as those at botanic gardens, and how that affects our success in rare plant reintroductions. Students, both undergraduate and graduate, are involved in several of these research projects.

Another area of interest involves the application of this research to improve conservation practice via promoting links between academic scientists and stewardship professionals. Much of my work focuses on increasing communication between these groups through workshops, symposia and task force groups, both to increase scientific input into management decisions and to feedback applied research questions to the academic community
