DESCRIPTION:Speaker: Konrad Lohse\nhosted by Nick Barton\nAbstract: Genome 
 scans for outliers of divergence are generally based on one dimensional su
 mmary statistics\, such as F_st or d_xy and have become a mainstay of spec
 iation research. Such scans suffer from a number of well known limitations
 . Most fundamentally\, they do not allow to connect sequence variation to 
 the population level processes. Interpretations of outlier scans are verba
 l and ignore the large variation inherent in the coalescent. I will descri
 be a general likelihood framework for model based scans that allows to qua
 ntify heterogeneity in effective gene flow and population size along the g
 enome. I will illustrate the insights that can be gained from this decompo
 sition of the genomic landscapes of speciation through an analysis of whol
 e genome data in two European sister species of Scarce Swallowtail butterf
 ly.
