Plant reproduction across lineages and environments
How do plants adapt and diversify? My research addresses this question by revealing macroevolutionary patterns of plant diversity using phylogenetic comparative methods and explaining them in terms of ecological and evolutionary processes. I thus work at the interface of evolutionary ecology and macroevolution. I am particularly interested in understanding patterns of plant reproductive diversity. I take a whole-plant approach, addressing the evolution of flowers and inflorescences in the context of plant architecture, function, and resource allocation. I work on multiple evolutionary scales, from populations (e.g., Primula halleri) to genera (e.g., Primula, Lewisia, Dracula, Saxifraga) and families (e.g., Montiaceae, Cactaceae, Primulaceae, Connaraceae). I also have an interest in herbarium taxonomy and the history of botany.
General, motivating questions of my work include:
- What are the limits of floral evolvability? Are these independent of vegetative traits?
- What are the functional implications of natural variation in floral and inflorescence morphology?
- How is reproductive diversity structured along ecological gradients?
- How are sexual systems associated with diversification dynamics and extinction risk?
- How do within-species patterns of variation relate to trajectories of macroevolutionary diversification?
Pursuing these fundamental questions helps to predict how plants adapt to changing environmental conditions.
