Ph.D. student in Simon Joly lab working on the evolution of flower morphology in an urbanization context 🌸 🐝 🌳🏙️| Interested in flower evolution, pollination, plant reproduction, local adaptation and conservation.
In the field, phenotypic plasticity masked the genetic differences observed in the common garden.

Urbanization influenced flower morphology through both plastic and genetic changes!

This counter-gradient variation means the environment dampens genetic adaptation—making evolution harder to detect!

Bumblebee size was also positively correlated with the genetic component of sepal size.

This suggests that bumblebee size is a key selective agent acting on Impatiens capensis sepal size

But wait—there’s more!

The difference in bumblebee size between urban and natural sites wasn’t the same in every city.

Interestingly, the genetic component of sepal size paralleled this result, the variation in sepal size following the one in bumblebee size.

We combined field and common garden experiments to study flower evolution in natural and urban habitats, disentangling plastic from genetic responses.

We surveyed pollinators and flower morphology of Impatiens capensis in 16 populations across the Quebec, Montreal, Ottawa, and Toronto regions.

Urbanization alters species richness, abundance, and even evolution—especially of pollinators.

Since pollinators form mutualistic interactions with plants, shifts in their diversity, abundance, or traits can drive selection on flower morphology.

Hi Brian, thanks for the list. Can I also be added please ?
