We are a team of scientists interested in a variety of ecological and evolutionary questions, especially involving the relationship between both disciplines and the theory of eco-evolutionary feedbacks. For the most part, we do our research on Trinidadian guppies (Poecilia reticulata) and their streams, but we are curiosity-driven and sometimes foray into other species and systems. Some of our research themes include:
- How does adaptation to density and resource availability affect nutrient cycling? How does in turn affect the evolution of guppy life history, morphology, behavior, and ecophysiology?
- How does dispersal evolve as populations spread? How does this affect their invasiveness?
- What are the demographic and evolutionary consequences of density and frequency dependent selection?
- How predictable and repeatable is rapid evolution and its ecosystem effects?
We approach these questions through the integration of mathematical models (statistical or theoretical) with long-term data, and manipulative experiments in the field, laboratory, and semi-natural environments (mesocosms).
