Unravelling the mystery of endemic versus translocated populations of the endangered Australian lungfish (Neoceratodus forsteri)

RADseq dataset of the Australian lungfish (Neoceratodus forsteri). The dataset is constituted of 100 samples and 5,196 nuclear SNPs. There are five populations each with 20 samples. IDs: BUR (Burnett River), MRY (Mary River), TIN (Tinana River), NPD (North Pine River), BNE (Brisbane River). The dataset is in VCF format.   Scripts for statistical calculations and demographic simulations.
