Genomic Signatures and Demographic History of the Widespread and Critically Endangered Yellow-Breasted Bunting.

ABSTRACT: Population declines may have long-term genetic consequences, including genetic erosion and inbreeding depression, which could affect species' evolutionary potential and increase their risk of extinction. Small populations are more vulnerable to genetic threats than common species, but even species with large populations can also be at risk of extinction. The yellow-breasted bunting (Emberiza aureola) is a common and widespread songbird in the northern Palearctic regions, but its global population size has drastically declined by around 90% throughout the past 30 years, leading to an upgrade of its conservation status to critically endangered in the IUCN Red List. In this study, we identified three populations within this species using whole-genome resequencing data, but the genetic differe
