Full description

Microsatellite data, raw SNP data, VCF files, R scripts, GBS analysis commands (stacks and vcftools), additional genome assembly data, mitochondrial genomes, and locations and dates of samples for the paper 'Reassessing hybridisation in Australian Tetragonula stingless bees using multiple genetic markers.' This paper re-examined reports of hybridisation in three cryptic stingless bee species in the genus Tetragonula in South East Queensland, Australia (T. carbonaria, T. davenporti, and T. hockingsi). Previous studies on this group using microsatellite markers proposed that hybridisation occasionally takes place. In contrast, we find that using 1,745 SNPs we could reliably separate the three species, with no evidence of contemporary (or recent) hybridisation. We found identical amplicon sequences of the nuclear gene EF1alpha across most individuals of the three species, but low and moderate species-specific polymorphisms in the nuclear gene Opsin and the mitochondrial 16S rRNA gene respectively, with no cases of mito-nuclear discordance at these genes. We confirm that nuclear divergence across these species is low, based on 10-26kb of non-coding sequence flanking EF1alpha and Opsin (0.7-1% pairwise difference between species).

The higher resolution provided by multiple SNP markers may lead to lower estimates of contemporary hybridisation more generally.
