My collaborators and I conducted field studies of flower pollination in the spring wildflower Collinsia and the tropical vine Dalechampia in order to understand the evolution of flower size and the role of floral specialization in increasing rates of speciation and/or promoting species coexistence and standing biodiversity. These two unrelated genera both
exhibit wide variation in flower size and degree of ecological specialization, and they form good systems for comparative studies in a phylogenetic context. Explaining the origins and maintenance of this variation and diversity remains the underlying theme of our research.
