Surviving the squeeze: Genomic analysis of a successful invasion by European common wall lizards (<em>Podarcis muralis</em>) in North America (Ohio, USA)

Invasive species that undergo a founder event may experience a decline in genetic diversity yet still establish successful populations despite the potential loss of adaptive variation and an increase in deleterious variation. This widely observed phenomenon is termed the genetic paradox of invasive species. A possible example is the common wall lizard (Podarcis muralis) in Cincinnati, Ohio, USA a successful invasive reptile founded by the introduction of a small number of individuals from Italy. In this study, we evaluated whether this introduction is an example of the genetic paradox of invasive species. Specifically, we examined the origin, demographic history, population structure and genomic diversity of the invasive common wall lizard using whole genome sequences of 35 individuals from the native and introduced locations across multiple time points. Phylogenetic analyses confirm that the invasive lizards in Ohio are likely derived from a population of Podarcis muralis in Northern I..., , , # Podarcis genomics README The following scripts & data provide information regarding three datasets Dataset A - Podarcis.filtered.final.SNPs.vcf.gz - GATK called variant call file that has been compressed Dataset B - LD.filtered.SNPs.2.pruned.vcf.gz - LD filtered version of Dataset A, GATK called variant call file that has been compressed Dataset 3 - multisample_filter2.all-sites.vcf.gz - Combined all-sites variant call file that has been compressed - available here: [https://buckeyemailosu-my.sharepoint.com/:u:/g/personal/bode_52_buckeyemail_osu_edu/IQDKq4Qm6Ym9TZ5rQsnyrEo6AUG4MIT5OhogJQMVxUjmXu8?e=p2prQk](https://buckeyemailosu-my.sharepoint.com/:u:/g/personal/bode_52_buckeyemail_osu_edu/IQDKq4Qm6Ym9TZ5rQsnyrEo6AUG4MIT5OhogJQMVxUjmXu8?e=p2prQk) Raw reads available on NCBI's Short Read Archive Database under BioProject Accession No PRJNA1284928 The reference genome used was: GCF_004329235.1_PodMur_1.0_genomic.fna found on NCBI's GenBank Files for analysis and Scripts used are bu..., ,
