Research Interests


I work on the ecology and the evolution of sexual polymorphisms in plants, i.e., species in which several sexual types (males/females; hermaphrodites/females) coexist in natural populations. My work mainly involves theoretical modelling, fieldwork in natural populations and measures on plants cultivated in greenhouse. Here are some questions I am interested in :

1. Consequences of dioecy (male and female plants) on pollination :

Can dioecy be a risk for plant pollination success and population survival ? How male and female plants compete for pollinator availability ?

2. How female plants can be maintained in competition with hermaphroditic plants ?

Does selection alone maintain the polymorphism ? What is the impact of population genetic structure ? Does population structure and selection interact with each other ?

3. Should one expect transitions from gynodioecy to dioecy ?
