From glacial echoes to timber pathways: Climatic–historical drivers and timber‐trade influence on the phylogeography of Ips sexdentatus in the Basque Country

Agricultural and Forest Entomology, EarlyView.
Ips sexdentatus is expanding across southern Europe, attacking multiple Pinus species and showing the ability to colonize trees at early stages of decline. Genetic analysis of 668 individuals revealed 106 haplotypes, with Iberian populations as diversity hotspots, reflecting long‐term refugial persistence alongside more recent demographic expansion ...
