Phylogeographic and Genomic Insights Unveil the Evolutionary History and Post-Glacial Recolonization Routes of the Palmate Newt (<i>Lissotriton helveticus</i>) Into Europe.

ABSTRACT: Quaternary glacial cycles have been key drivers of diversification for Holarctic species, promoting divergence, isolation, and extinction processes in numerous taxa. These cycles facilitated evolutionary radiations in some groups but also erased much of the evolutionary history of species with northern origins. Here, we investigate the evolutionary and phylogeographic history of the Palmate Newt (Lissotriton helveticus), a widespread species in post-glacial ecosystems in Western Europe. We generate genome-wide ddRADseq for 205 individuals from 51 populations across the species range and reconstruct its phylogeographic and demographic history, assess population structure, and characterize ecological paleoniches for the species at different climatic periods. Results identify several d
