Northern European Salmo trutta (L.) populations are genetically divergent across geographical regions and environmental gradients
The salmonid fish Brown trout is iconic as a model for the application of conservation genetics to understand and manage local interspecific variation. However, there is still scant information about relationships between local and large-scale population structure, and to what extent geographical and environmental variables are associated with barriers to gene flow. We used information from 3,782 mapped SNPs developed for the present study and conducted outlier tests and gene–environment association (GEA) analyses in order to examine drivers of population structure. Analyses comprised >2,600 fish from 72 riverine populations spanning a central part of the species' distribution in norther…
data for: Northern European Salmo trutta (L.) populations are genetically divergent across geographical regions and environmental gradients.
SNP genotype data used in: Bekkevold, D. , Höjesjö, J. , Nielsen, E. E., Aldvén, D. , Als, T. D., Sodeland, M. , Kent, M. P., Lien, S. and Hansen, M. M. (2019), Northern European Salmo trutta (L.) populations are genetically divergent across geographical regions and environmental gradients. Evol Appl. doi:10.1111/eva.12877.The file is a comma-separated text file, where each row gives a list of 3782 genotypes; one row per individual (2090 total). Each individual is denoted by its collection ID, given as a 'River number' following Table 1 in Bekkevold et al. (doi:10.1111/eva.12877), followed by an underscore (_), followed by 'Individual number'. Individual SNP locus names are given in the top…
