Detecting footprints of adaptive phenotypic differentiation in the wild
Friday seminar by Juha Merilä
Differentiating in between adaptive and non adaptive causes of population differentiation in phenotypic traits of ecological interest remains often a challenge for empirical studies of natural populations. I will review a series of yet unpublished empirical studies which have utilized newly developed quantitative genetic approach to differentiate in between natural selection and genetic drift as a cause of population differentiation. Apart from of aiming to illustrate the general utility of this approach, I hope introduce couple of illuminating empirical case-studies where footprints of adaptive differentiation can be recovered in spite of strong influence of genetic drift and gene flow, respectively. There is certain - yet undefined - probability that my talk takes a totally different path than that depicted in this abstract.
