Heterogeneous patterns of heterozygosity loss in isolated populations of the threatened eastern barred bandicoot (Perameles gunnii)

Perameles gunnii is an endangered terrestrial marsupial on mainland Australia, but comparitively widespread in Tasmania. No research has yet aimed to assess population structure or genetic diversity in this state until now, where we assess genomic similarity and diversity using a ddRAD dataset of 117 Tasmanian animals.
First, we assigned all samples to populations (or demes), according to their coordinate metadata and known geographic boundaries. We then test this hypothesis with population-ignorant genetic clustering analyses: PCA, Structure, and fineRADstructure. Validating seven (7) populations, four in a distinct \"northern\" group and three in a \"southern\" groupd, and also identify two populations displaying significant and unexpected isolation. We then looked to directly assess migration between these populations find little evidence, although genetic similarity within nothern and southern groups suggests that gradual mixing is ongoing within these areas.

Genotypic data and metadata for 117 Tasmanian Perameles gunnii, sampled from the wild between 2008-2011, and 17 Victorian *Perameles gunnii* from Mt Rothwell Biodiversity Interpretation Centre, sampled from 2016.

Samples provided as demultiplexed raw reads in .fq.gz format, and a draft scaffold genome is provided in .fa format.

Metadata contains incomplete coordinate data approximated to two (2) decimal places to protect a sensitive species, as per The Global Biodiversity Information Facility (Category 3 sensitive species). Where exact coordinate data was unavailable, approximate data was inferred from the recorded locality, and whether coordinates are exact or approximate is indicated in the metadata. Metadata also contains incomplete sex data; where sex was unknown, NA has been used to indicate this.

Additionally, publicly available, post-1990 sighing data for *P. gunnii* in Tasmania is available in ALA. Also, the distribution map figure ...
