ABSTRACT Understanding the diversity and ecological evolutionary history of plant species is crucial for addressing current biodiversity crisis comprehending processes by which organisms fill geographic spaces. In this study, we present a comprehensive analysis Diphasiastrum digitatum Holub from lycophyte lineage plants, using microsatellite genotyping data biogeographic analyses. Based on available transcriptome assembly, generated numerous markers utilized 13 robust to genotype collection 402 specimens Eastern US (VT; VA; NC; TN). accordance with accepted phylogeny, cross‐amplification tests demonstrated closer relationship between D. spp. compared Lycopodium Furthermore, population genetics analyses identified two genetic clusters within suggested ongoing divergence expansion. Isolation‐by‐distance indicated that distance had minimal effect differentiation, whereas environmental variables related water regime were strongly associated variance. Ecological niche modeling showed post‐Last Glacial Maximum expansion southern refugia, corroborating similar scenario based our data. Overall, study provides valuable insights into clubmosses highlights migration events factors shaped their distribution.
