In temperate climates with strong seasonal changes, plants need to decide how to allocate resources to vegetative growth or to reproduction during a potentially short favorable season. Many plants switch from mostly vegetative growth early in the season to mostly reproduction late in the season. The onset of flowering marks the transition between the two phases. Later onset of flowering typically implies a larger size at maturity and higher reproductive capacity. At the same time, it limits the remaining time in the favorable season for pollination and seed development. Hence, plants face a trade-off for some optimal flowering onset. In this talk, I will present a seasonal hybrid model for the density of a plant population, structured by onset of flowering as a trait. I will apply two complementary approches to analyze the system. Overall, I find that evolution favours some intermediate flowering times. This is joint work with Tricia Morris.

This seminar is jointly run by CMM, CAMBAM and the University of Waterloo.
