Phylogeographic analyses suggest that a deciduous species (Ostryopsis davidiana Decne., Betulaceae) survived in northern China during the Last Glacial Maximum (original) (raw)

Phylogeographic analyses conducted on Ostryopsis davidiana, a deciduous species in northern China, indicate that this species likely survived the Last Glacial Maximum (LGM) due to the presence of glacial refugia. The study utilizes molecular evidence to assess genetic diversity and historical distribution, suggesting that certain populations retained genetic signatures from the LGM, which contrasts with previous hypotheses suggesting a complete migration southward. These findings underscore the importance of glacial refugia in maintaining biodiversity amidst climatic changes.
