Description of the different Carcharhinus leucas datasets used in this study.
| Data set | Genotyping method | Data description | Usage | Before filtering | After filtering |
|---|---|---|---|---|---|
| DArTseq1 | DArTseq | Full global dataset including replicates and other species | For species identification (allow more missing data and higher levels of heterozygosity) | 218 sharks; 250,945 SNPs | 218 sharks; 28,418 SNPs |
| DArTseq2 | DArTseq | Full global dataset with only Bull Shark samples | For DArTcap marker selection | 182 sharks; 250,945 SNPs | 149 sharks; 17,029 SNPs |
| DATA1 | DArTcap | Full global dataset including replicates and other species | For species identification (allow more missing data and higher levels of heterozygosity) | 1014 sharks; 37,537 SNPs | 1014 sharks; 5053 SNPs |
| DATA2 | DArTcap | Global dataset with confirmed Bull Sharks | For genetic diversity, FST, and provenance assignment | 868 sharks; 37,537 SNPs | 769 sharks; 3409 SNPs |
| DATA3 | DArTcap | Global Bull Shark dataset with a subset of 60 samples from Australia | Equalized sample size to allow unbiased clustering analyses | 430 sharks; 37,537 SNPs | 382 sharks; 1849 SNPs |
| DATA4 | DArTcap | All western Atlantic Bull Shark samples | For genetic diversity estimates without bias from population structure | 117 sharks; 37,537 SNPs | 91 sharks; 931 SNPs |
| DATA5 | DArTcap | All Indo‐West Pacific Bull Shark samples | For genetic diversity estimates without bias from population structure | 732 sharks; 37,537 SNPs | 635 sharks; 3416 SNPs |
| DATA6 | DArTcap | IWP data with a subset of 60 samples from Australia | Equalized sample size to allow unbiased clustering analyses | 221 sharks; 37,537 SNPs | 189 sharks; 1785 SNPs |
Note: The data generated by DArTseq and DArTcap genotyping were subdivided to account for unequal samples sizes and hierarchical clustering. The number of sharks and SNPs before and after quality filtering are presented.
