Variation in thermal optima of gametes and floral thermoregulation across an elevation gradient in southwestern Colorado

Highly mobile animals can behaviorally thermoregulate, but most plants are rooted, and are thus subject to highly variable thermal environments. Some plants have evolved mechanisms to alter the abiotic floral microenvironment which could mitigate damage to pollen and ovules caused by thermal stess.  I’ll present recent work examining whether high elevation and low elevation populations of a widespread herb, silverweed cinquefoil, have evolved different thermal optima for gamete performance. I’ll then discuss mechanisms by which the flowers warm (or cool) the gamete environment. Finally, I’ll discuss the fitness consequences of floral warming.

Everyone is welcome to join the seminar, please email jacki.craig@ucdenver.edu to receive the Zoom link. Requests can be submitted any time before the seminar but not after 10:00am the day of the seminar.
