| Summary: | Despite decades of research assessing the genetic structure of natural populations, the biological meaning of low yet significant genetic divergence often remains unclear due to a lack of associated phenotypic and ecological information. At the same time, structured populations with low genetic divergence and overlapping boundaries can potentially provide excellent models to study adaptation and reproductive isolation in cases where high-resolution genetic markers and relevant phenotypic and life history information are available. Here, we combined single nucleotide polymorphism (SNP)-based population inference with extensive phenotypic and life history data to identify potential biological mechanisms driving fine-scale subpopulation differentiation in Atlantic salmon (Salmo salar) from the Teno River, a major salmon river in Europe. Two sympatrically occurring subpopulations had low but significant genetic differentiation (FST = 0.018) and displayed marked differences in the distribution of life history ... : Aykanat_et_al_Dryad_filesFILES IN THE BUNDLE: mainparams: parameter file for the structure runs. NOTE that k and n are "number of populations" and "number of replicate", respectively and appropriate number should be used instead of these letters when running the software. teno_MS = The GenABEL format main file. The file includes genotype (n= 2874 SNPs), phenotype as well as location information from 662 individuals, which is sufficient to replicate the main results. Structure raw files.zip = Includes raw results from the structure analysis which is sufficient to replicate all structure related results. ... |
