The overarching context of my research program is to bridge the understanding that ecologists and evolutionary biologists have gained about how evolution operates within populations and the understanding that systematists and evolutionary biologists have gained about the patterns of biodiversity observed at large spatial and temporal scales. In pursuit of my research goals, I have conducted intensive studies on the phylogenetic relationships of milkweeds (Apocynaceae, Asclepiadoideae), selection on floral traits by pollinators, the dynamics of hybridization driven by variation in floral scent chemistry, and the evolution of defenses against herbivory. My approach emphasizes (1) phylogenetics analyses of plant lineages and (2) the inference and hypothesis testing of evolutionary and ecological processes that produce biological diversity.
BOT 3005 Field Botany, fall semesters. Prerequisite: BIOL 1114. Botanical field techniques, the vegetation of North America, and the flora of Oklahoma. Terminology of description, use of taxonomic keys, techniques of specimen preservation, field recognition of plant taxa and communities and controlling ecological factors, economic and wildlife significance of dominant taxa, principles of classification and nomenclature. Four weekend field trips required.
