Amber Rice, Ph.D.

By measuring traits and reproductive success in the wild, we seek to understand the influence of particular phenotypes (e.g., morphology, behaviors) on fitness in ecologically relevant settings. Here, the amount of white on the wing of a male collared flycatcher (Ficedula albicollis) is being measured. Photo credit: L. Thunström

We study the initiation of speciation in different populations of spadefoot toads (genus Spea). The tadpoles of these species can develop as one of two morph types: an omnivore or a carnivore. Here, a carnivore morph is preying on an omnivore morph. Photo credit: D. Pfennig

Research Overview

The primary goal of my research is to understand the ecological and evolutionary mechanisms underlying the process of speciation, from the early stages to its completion. I focus particularly on the importance of species interactions and selection in driving this process. To do this, I combine ecological field studies with population genetic and genomic studies in several species.

More specifically, my lab seeks to understand:

  1. how ecological and reproductive character displacement can initiate speciation and lead to reproductive isolation.
  2. the genomic and ecological consequences of hybridization.
  3. how speciation proceeds in spite of gene exchange between diverging populations or species.
