Here, we investigate the population structure and demographic history of ectomycorrhizal fungus\n                    <jats:italic>Rhizopogon salebrosus<\/jats:italic>\n                    , a symbiont of\n                    <jats:italic>Pinus<\/jats:italic>\n                    species, across the Madrean Sky Islands Archipelago (MSIA) of southern Arizona and northern Sonora.\n                    <jats:italic>Rhizopogon salebrosus<\/jats:italic>\n                    produces truffle\u2010like sporocarps and depends on small mammals for spore dispersal. Using genome\u2010wide data from sporocarps and bioassay\u2010derived root tips sampled across seven mountain ranges, we assessed patterns of genetic structure, divergence, and connectivity across this fragmented landscape. We identified strong geographic structuring consistent with island\u2010like population differentiation, accompanied by rare signals of admixture. Genetic divergence among populations increased with geographic distance, and demographic inference supports long\u2010term isolation associated with historical habitat fragmentation, with limited recent gene flow among islands. Together, these results highlight the lasting influence of past climate\u2010driven landscape dynamics on fungal population structure and emphasize the role of geographic isolation in shaping the evolutionary history of symbiotic fungi in montane systems.\n
