ABSTRACT How genetic variation contributes to adaptation at different environments is a central focus in evolutionary biology. However, most free‐living species still lack comprehensive understanding of the primary molecular mechanisms adaptation. Here, we characterised targets selection associated with drastically aquatic environments—humic and clear water—in common freshwater fish, Eurasian perch ( Perca fluviatilis ). By using whole‐genome sequencing (WGS) on large population dataset n = 42 populations) analysing 873,788 SNPs, our aim was uncover novel confirm known footprints selection. We compared individual pooled WGS, developed approach, termed dynamic outlier slicing, assess how choice outlier‐calling stringency influences functional Gene Ontology (GO) enrichment. integrating genome‐environment association (GEA) analysis allele frequency‐based approaches, estimated composite signals (CSS) identified 2679 SNPs distributed across 324 genomic regions, involving 468 genes. Dynamic slicing robust enrichment five annotation categories (upstream, downstream, synonymous, 5′UTR 3′UTR) highlighting crucial role regulatory elements adaptive evolution. Furthermore, GO analyses revealed strong functions gated channel activity, transmembrane transporter activity ion emphasising importance osmoregulation balance maintenance.

Whole Genome Sequencing (WGS) remains a costly or unsuitable method for routine genotyping of laying hens. Until now, breeding companies have been using developing SNP chips. Nevertheless, alternatives methods based on sequencing developed. Among these, reduced representation approaches can offer quality and cost-effectiveness by reducing the genomic regions covered sequencing. The aim this study was to evaluate ability double digested Restriction site Associated DNA (ddRAD-seq) identify genotype SNPs in hens, comparison with presumed reliable WGS approach.
