Data from: Genomic tests of the species-pump hypothesis: recent island connectivity cycles drive population divergence but not speciation in Caribbean crickets across the Virgin Islands

Amphiacusta_5558SNPs_StructureFile.txtA structure format file containing 5,558 single bi-allelic SNPs that were used for assessing population structure and genetic differentiation (for STRUCTURE, PCA and procrustes analyses, IBD and estimation of genetic diversity statistics).Amphiacusta10pops5558SNPsStructure.txtAmphiacusta_82443SNPs_ForQuartets.txtA phylip file containing 82,443 single bi-allelic SNPs that were used for the quartet analysis (in SVDquartets).Amphiacusta82443SNPsForQuartets.txtsampleDownMSFS.pyPython script that downsamples the population sizes and calculates the joint folded Site Frequency Spectrum (for the minor allele frequency) of two populations based on a vcf file. Includes an example vcf input file and population map.sampleDownMSFSWithExampleInputFiles.zipInputFilesForFastsimcoal.zipA set of folders containing the input files for analyses with fastsimcoal2, including the calculated joint Site Frequency Spectrum for each of the focal population pairs. Folder and file names follow the population codes used consistently throughout the manuscript.
