The vast diversity observed in morphology and life history in the threespined stickleback (Gasterosteus aculeatus L.) species complex continues to trigger evolutionary research on mechanisms and evolutionary rates. Particularly interesting are the very early steps of population differentiation which may illuminate what kind of traits and mechanisms are important during this initial phase of speciation. In our project (K. Østbye / A. Vøllestad) we will apply population genetic tools and morphology to study phylogeny, population differentiation, and funtional adaptive divergence. We aim at integrating quantitative genetics, behaviour and physiological experiments to quantify adaptive trait divergences, and to suggest the most likely evolutionary scenarios. The project is a collaboration with several institutions; Tom Klepaker (University of Bergen), Louis Bernatchez (University of Laval, Quebec), Paul Hart (University of Leicester), Chris Harrod (Max-Planck-Institute for Limnology, Plön), and Dolph Schluter (University of British Columbia, Vancouver). I have some experience with population genetics from my Dr. scient. work covering the polymorphic European whitefish (Coregonus lavaretus L.) species complex.
