California Botanical Society Annual Meeting and Banquet Performing Arts Center Pavilion 5-6 pm Botany Mixer 6-7:45 pm Annual banquet with keynote speaker David Lowry 7 pm — Keynote Address by Dr. David Lowry Dr. David Lowry grew up in Sonoma County, where he frst came to appreciate fog and the strong environmental gradient between coastal and inland habitats of California. He attended UC Berkeley and received a BS in Genetics and Plant Biology in 2001. Lowry studied the evolution of coastal and inland ecotypes of the yellow monkeyfower, Mimulus guttatus, for his PhD at Duke University, which he received in 2010. He then went on to a postdoctoral position at the University of Texas, Austin, where he studied evolutionary adaptations in switchgrass, Panicum virgatum. Since 2014, Lowry has been an assistant professor in the Department of Plant Biology at Michigan State University.

Dr. Lowry’s talk will focus on understanding the evolution of coastal and inland ecotypes of the yellow monkeyfower in western North America. Particular attention will be paid to the environmental factors driving the formation of ecotypes and the genetic and physiological changes underlying their evolution.
