show Abstracthide AbstractThis study aims to characterize genomic divergence in three marine limpets (Scurria scurra, S. araucana, and S. ceciliana) across two biogeographic barriers in the Southeastern Pacific (30-34S and 41-43S) using whole-genome resequencing data. It identifies regions under selection and evaluates divergence models, contributing to understanding adaptation and speciation in connected marine environments.
