Perspectives on Plant Diversity

Instructor:
Dan Potter, Department of Pomology, College of Agricultural and Environmental Sciences

Description: In this seminar, we will explore various disciplinary and cultural perspectives on issues related to biological diversity, focusing on plants. We will begin by defining terms. What is a plant? What do we mean by diversity? How do the definitions of these terms vary depending on who is using them and how have they changed through history? We will compare and contrast various ways of representing and organizing botanical diversity, including a range of ethnobotanical classifications, traditional western scientific taxonomy, and modern phylogenetic classifications, as well as linguistic and artistic expressions. What are the common themes and key differences, and what do they tell us about how people perceive other organisms? We will also examine the significance of plant diversity to people from a range of perspectives, including the cultural, economic, ecological, and aesthetic components that contribute to individuals’ and society’s appreciation and valuation of diversity. How important is maintaining plant diversity to human survival and welfare? Finally, we will discuss the various approaches that have been taken to conserve the diversity of plants at different levels, including habitat conservation, protection of endangered species, and in situ and ex situ germplasm preservation. What are the challenges involved in developing and implementing conservation strategies and how can they be resolved? These issues will be explored through a combination of lectures and demonstrations given by the instructors, class discussions, visits to several botanical collections on campus, and student team research projects and presentations. The team projects will consist of investigations into an interdisciplinary topic related to plant diversity. Examples of possible topics include: protection of rare and endangered plants in California such as vernal pool or serpentine endemics; effects of genetically modified plants on diversity of traditional landraces in a particular crop; effects of human migrations and cultural exchanges on the plants used by one or more cultural groups; historical changes in the vegetation of California. We hope to attract students with a diversity of interests and academic and cultural backgrounds. Because we will take an interdisciplinary approach and examine both fundamental and applied aspects of issues of plant diversity, we expect that all students will be exposed to new perspectives as a result of participating in this seminar. In class discussions and in the team projects conducted by students, we will specifically encourage individuals to look at issues from perspectives that are different from those that are most familiar. Thus, students with strong backgrounds in biology would be encouraged to consider cultural and/or legal perspectives. Weekly writing assignments will request students to make connections between class material and past or current personal experiences or world events.

Format:. The seminar will meet once a week for one hour and fifty minutes throughout the quarter, Mondays from 1:10 to 3 PM. Several field trips are scheduled. Each student will be required to keep a weekly electronic journal, consisting of a minimum of one page of text relating what was discussed or observed in class that week to something that the student experienced, heard, or read about outside of class. Each student will also participate in the team research projects and preparation for the end-of-quarter presentations. Some time will be allowed in class for students to work on the projects. Students will prepare self and peer evaluations for team members. Grading: Grades will be based on: In-class participation 20%; Weekly electronic journal entries 50%; Team projects 30%.


About the Instructor: Professor Potter is a member of the faculty in the recently established Department of Plant Sciences in the College of Agricultural and Environmental Sciences. The primary focus of his research is angiosperm systematics, the study of the diversity, phylogeny, and classification of flowering plants, especially crop plants and their wild relatives. Specific projects include examinations of phylogenetic relationships and character evolution across Rosaceae, the rose family, using DNA sequence data, and of the relationships between one group of species in that family and the nitrogen-fixing bacteria with which they form symbiotic associations. He also has an active interest in ethnobotany, the study of the direct relationships and interactions between plants and people. He participates in teaching the following courses: Plants and the Biosphere, California Floristics, Principles and Methods of Ethnobotany, and the Genetics and Evolution portion of the Plant Biology Graduate Group Core Course. Graduate student and co-instructor Jennifer Petersen is pursuing her Ph.D. through the Plant Biology Graduate Group. Her research focuses on systematics of the tropical plant family Sapotaceae, which includes many species that yield timber, latex, and edible fruits.
