Research Interests: behavioral ecology; avian mating systems; populations genetics.

Dr. Tuttle is interested in the evolution of behavior, populations, and species. Specifically, she examines how ecology, behavior, genetics, and physiology maintain natural variation through their influence on the evolution of life-history strategies, phenotypic expression, and both the relative fitness and frequency of genotypes within a population. Dr. Tuttle is currently involved in two projects that investigate these factors: 1) a study of the maintenance of polymorphism via disassortative mating in the white-throated sparrow (Zonotrichia albicollis), and 2) a study of sexual selection and the evolution of mating systems in Australian fairy-wrens (Malurus splendens, M. lamberti, M. leucopterus) in collaboration with Stephen Pruett-Jones (University of Chicago) and Michael S. Webster (Washington State University).

Dr. Tuttle's work on white-throated sparrows and fairy-wrens examines how individuals maximize fitness through the differential allocation of time, energy, and resources. Both research projects examine 1) how individuals balance various life history trade-offs, and 2) how life-history trade-offs generate variance that affects the evolution of sexually-selected characters. Dr. Tuttle's research differs from conventional evolutionary study in that she often employs concepts and techniques borrowed from other disciplines.

Dr. Tuttle utilizes observational and experimental methods in the field and laboratory, molecular genetic techniques (e.g. minisatellite DNA fingerprinting, microsatellites, RAPDs, AFLPs), physiological techniques (e.g. semen sampling, hormonal analyses, and immunological analyses), and other multi-disciplinary techniques (e.g. karyotyping, histology). An integrative approach often reveals new alternative hypotheses and allows her to investigate evolutionary questions at proximate and ultimate levels.

Dr. Tuttle has a general interest in population genetics, the nature and organization of genetic variation in populations, and how genetic diversity affects the conservation of species. She has collaborated on several such research projects on a variety of organisms ranging from mammals to insects.
