| Summary: | Measuring the effects of selection on the genome imposed by human-altered environment is currently a major goal in ecological genomics. Given the polygenic basis of most phenotypic traits, quantitative genetic theory predicts that selection is expected to cause subtle allelic changes among covarying loci rather than pronounced changes at few loci of large effects. The goal of this study was to test for the occurrence of polygenic selection in both North Atlantic eels (European Eel, Anguilla anguilla and American Eel, A. rostrata), using a method that searches for covariation among loci that would discriminate eels from “control” vs. “polluted” environments and be associated with specific contaminants acting as putative selective agents. RAD-seq libraries resulted in 23,659 and 14,755 filtered loci for the European and American Eels respectively. A total of 142 and 141 covarying markers discriminating European and American Eels from “control” vs. “polluted” sampling localities were obtained using the Random ... : A.anguilla_genotypes.targenepop file for A.anguilla individualsa.anguilla_genotypes.tar.gzA.rostrata_genotypesGenepop file containing genotype for all A. rostrata individualsImportant_marker_annotation.tarAnnotation results for the important markers.Markers and Important markersGenpop files (in a slightly modified format used for the random forest and contaminants work) of all markers for both eel species, in addition to the identification and statistics of important markers, the similarity matrix obtained from these important markers and the PCoAs produced from these similarity matrix.bayescanPollutantsIndividual contamination of 24 organic and 10 metal pollutants for both species.Database link.tarA csv that links each individual with their BioSample Accession in SRAdatabase link.txt ... |
