The main thrust of my research is to understand the ecological and genetic forces that control phenotypic diversity and shape adaptive evolution in plants. At a more general level, I am interested in the interplay between ecology and evolution, addressing questions from molecular evolution to population ecology. My research combines observations from wild populations and manipulative experiments, demographic and population projection modeling, and population genetics to gain insights into the selective forces in natural populations and their consequences for population persistence and evolutionary change.
Plant Biology, BOT 1404, odd numbered springs.
Prerequisite: BIOL 1114. Morphology and anatomy of plants. Plant functioning: photosynthesis, water relations, translocation hormonal regulation, photoperiodism. Survey of the plant divisions, algae and fungi.
General Ecology, BIOL 3034, every Fall.
Prerequisites: BOT 1404, ZOOL 1604 or equivalent, MATH 1513 or 1715. Physical and biotic environment, responses of organisms to the environment, behavioral and community ecology, natural ecosystems and man's interaction with ecosystems.
Plant Ecological Genetics, BOT 5563, even numbered springs. Prerequisite(s): BIOL 3023, 3034, and/or ZOOL 4133 or equivalents. Basic concepts in plant population and quantitative genetics, focusing on techniques that reveal the genetic structure and the adaptive value of ecologically relevant traits.
