About the seminar: I will summarise two research projects investigating different mechanisms of plant mating system adaptation to rapid environmental variation. The first one explores contemporary evolution in entomophilous, short-lived arable weeds in response to climate change and pollinator decline using the resurrection approach. This approach consists of resurrection ancestral genotypes harvested in natural populations in the past and stored in seed repositories for several generations, then growing them side-by-side with their contemporary descendants harvested in the same population at present. The second one explores the adaptive value of plastic cleistogamy; a mixed-mating system where plants produce variable proportions of closed (cleistogamous) flowers which are obligately self-pollinated, and open, chasmogamous flowers which are potentially outcrossed. I investigate how cleistogamy varies between natural populations coming from contrasting climates and habitats, whether this variation is due to plasticity or genetic differentiation, and whether it confers an adaptive reproductive advantage in response to environmental variation.
