Genomic patterns of phenotypic adaptation in Italian wall lizard <i>Podarcis siculus</i> (Rafinesque-Schmaltz, 1810)

Within a competitive exclusion experiment conducted in 1971, five pairs of <i>Podarcis siculus</i> lizards were transferred from islet Pod Kopište to a nearby islet of Pod Mrčaru in the Adriatic Sea. In only 35 years the newly established population exhibited significant morphological and ecological changes. This study combines experimental common garden approach with population genomics tools to discriminate between plastic and genomic response in Pod Mrčaru population. Crossing experiment in common garden pointed towards medium to high heritability of diverged phenotypic traits related to head shape, indicating they hold enough additive genetic variance to evolve under selection. Genotyping by sequencing elucidated genome-wide divergence between Pod Mrčaru and Pod Kopište populations. 18 loci putatively under selection were found to be associated with divergent phenotypic traits in source and newly established population, and/or differences in ecological variables among multiple <i>P. siculus populations</i>, suggesting rapid genomic adaptation on the islet of Pod Mrčaru.
