- Organismal Botany
- Paleontology
- Evolution and Phylogeny
Studies of fossil and living land plants are directed toward a fuller understanding of phylogeny and evolution. These are explored using data from morphological, anatomical, ultrastructural, developmental, and molecular characters. Evaluations of ontogeny, reproductive biology, and organismal interactions are emphasized in interpreting development of the modern flora within the context of evolutionary ecology.
Research projects on a wide range of organismal biology topics are available for both undergraduate and graduate students who wish to become practicing scientists. These studies often focus on fossil plants, but structure, growth and development and physiology studies of living plants also are conducted. Anyone interested in doing original research and/or conducting his or her PBIO 404 undergraduate research in organismal botany, may contact Dr. Rothwell for a list and explanation of available topics.
