Single Nucleotide Polymorph and location metadata for Turbo militaris from Eastern Australia

Studies of population genomics have been increasingly used to identify climate change vulnerability and explore the potential resilience of harvested marine species. The turban snail, Turbo militaris is a commercially and culturally harvested marine gastropod snail from eastern Australia. The species has exhibited a climate-driven poleward range shift over the last two decades and continued climate change presents an ongoing challenge for sustainable fisheries management. This study investigates the likely resilience of Turbo militaris to future climate change effects using genotype-by-sequencing to explore patterns of gene flow and local adaptation across the entire species distribution. We provide evidence of a single admixed, and potentially panmictic, demographic unit with no evidence of genetic subdivision across the species range. Furthermore, significant genotype associations with heterogeneous habitat features were observed, including associations with sea surface temperature, o..., Eight rocky shore locations (0 to 5m depth) were selected for sampling spanning theknown range of T. militaris from Hastings Point (northern NSW) to Jervis Bay (southern NSW) representing a seven-degree latitudinal and a 3.9°C annual mean sea surface temperaturegradient. Between 25 and 30 T. militaris individuals were collected fromeach location. For single nucleotide polymorphism (SNP) genotyping, extracted DNA was sent toDiversity Arrays Technology Pty Ltd (Canberra, Australia) (DArT). The DArT organisationprovides a process pipeline of whole-genome profiling, without the need for a reference genome. High-throughput DArTseq technology was used to genotype Turbomilitaris DNA. Here, the PstI-based complexity reduction method (Wenzl et al. 2004) wasapplied for the enrichment of genomic representation with single copy sequences. This methodinvolved the digestion of DNA samples with a cutting enzyme PstI, paired with a set ofsecondary frequently cutting restriction endonucleases, ligation ..., , # Australian Turbo militaris SNP data and metadata

This dataset contains single nucleotide polymorph SNP 2 data generated by Divertisty Arrays Technologies DArT sequencing process - see https://www.diversityarrays.com/ for the marine turbinid gastropod Turbo militaris from across its entire range in NSW, Australia. Analysis using standard SNP population genetics scripts in R revealed panmixia across its range.

## Description of the data and file structure

There are two data files - both. csv files. The first is a SNP data set generated by DArT next generation sequencing technologies. The second is the site metadata for each of the individuals in the SNP dataset. File structure in the SNP dataset is as per the proprietary outputs from DaRT technologies. Data in this file can be analysed using the standardised DArT workflow analysis.
