    SLO Vets Hall
    801 Grand Ave, San Luis Obispo, CA 93401, USA

    Speaker: Dena Grossenbacher, Alpine plant diversity on Yosemite’s Sky Islands

    Dena Grossenbacher is a new Assistant Professor of Botany at CalPoly. She is broadly interested in how plant-environment interactions generate and maintain plant diversity, and the processes underlying the origin and extinction of species. She uses the California flora,
    especially monkeyflowers, to address these questions because of their astonishing variation both among and within species.

    Dena received a Bachelor’s degree in Botany in 1999 from University of Washington, was a field botanist in the Pacific Northwest and the Yosemite region from 2000-2008, and received a Ph.D. in Population Biology from UC Davis in 2013 with Maureen Stanton. She did postdocs studying mating system evolution at University of Minnesota and at Washington State University before arriving at Cal Poly
    in January 2017.

    Chapter meetings are generally held the first Thursday of the month at the San Luis Obispo Vets Hall on Grande Ave near the corner of Monterey Street.

    Our meetings kick off with a social time that begins at 7:00 p.m.  This  is a time to sample the treats that members have brought along to share,  and browse the book table. The meeting starts at 7:30 p.m. with some  brief announcements before the program begins.

    Speakers and notes from Chapter Meetings are documented in each  Obispoensis newsletter. Please see the Obispoensis archive for PDF file  of each newsletter.
