Fig. 1: The locations (blue points) of all black-footed tree-rat (Mesembriomys gouldii) tissue samples collected for population genomic analysis.

Points are sized are relative to the number of samples collected from each locality. The dark grey shading indicates the current range of the black-footed tree-rat (Woinarski and Burbidge 2016). Light grey shading represents biogeographic barriers that are thought to drive population structure in other taxa. Note that the samples from the Oenpelli and Daly River localities (italicised) were removed during filtering due to low data quality.
