Abstract

Genomic regions displaying outstanding correlation with some environmental variables are likely to be under selection and this is the rationale of recent methods of identifying selected loci and retrieve functional information about them. To be efficient, such methods need to be able to disentangle the potential effect of environmental variables from the confounding effect of population history. For the routine analysis of genomewide data-sets, one also need fast inference and model selection algorithms. We describe a method based on an explicit spatial model that builds on the theoretical and computational framework developed by Rue et al. (2009) and Lindgren et al. (2011
