Mulgara (&lt;i&gt;Dasycercus&lt;/i&gt; spp.; Marsupialia: Dasyuridae), a widely distributed mammal taxon, offers an opportunity to explore patterns of the population structure across the region, previously hampered by taxonomic confusion surrounding extant species. Here, we aimed to (1) clarify the current distribution of extant &lt;i&gt;Dasycercus&lt;/i&gt; lineages, (2) describe the population genomic structure of the widespread brush-tailed mulgara, and (3) determine whether observed patterns of population genomic structure in brush-tailed mulgara are consistent with biogeographic breaks.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Location&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Arid and semi-arid regions of Australia.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Taxon&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Two species are extant; the brush-tailed mulgara (&lt;i&gt;D. blythi&lt;/i&gt;) and the crest-tailed mulgara (&lt;i&gt;D. hillieri&lt;/i&gt;, previously &lt;i&gt;D. cristicauda&lt;/i&gt;).&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;We sampled individuals from contemporary and museum tissue collections, obtaining next-generation sequencing data for 311 individuals, retaining 4360 single-nucleotide polymorphisms (SNPs) for population genomic analysis.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;We found that the two extant species are clearly delineated, corresponding well to current understanding of their respective distributions. The population genomic substructure in the brush-tailed mulgara (211 samples, 2740 SNPs) aligns primarily with major drainage divisions. Inference of historical population size change indicated that all populations have likely had stable population sizes for much of the past 1000 years, although post-European colonisation declines in some populations cannot be ruled out. The Pilbara population was most differentiated from other populations and displayed a stronger pattern of isolation-by-distance.

Present-day habitat suitability was modelled by bias-corrected SDMs with target group background and spatial thinning via semi-variogram measures, using a 1 km resolution dataset that included climatic, edaphic, and topographic variables. For projections under future scenarios, we utilised four shared socioeconomic pathways (SSPs), adopted from the AdaptWest database and modelled by employing ensemble means from eight Coupled Model Intercomparison Project Phase 6 Atmosphere–Ocean General Circulation Models.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Ensemble projections consistently show a decline in suitable habitat for &lt;i&gt;Fagus grandifolia&lt;/i&gt; across all future climate scenarios, with losses outweighing gains.
