Abstract

This article investigates how climatic shifts influence genetic structure and species boundaries between two Taiwan endemic gingers, *Zingiber pleiostachyum* and *Z. shuanglongense*. Using multilocus genetic data and species distribution modeling (SDM), the study finds well-defined genetic differentiation with limited hybridization likely resulting from secondary contact during the Last Glacial Maximum (LGM). Although the two species occupy similar but not identical ecological niches, differences in altitudinal distribution and seed dispersal capabilities contribute to their geographic segregation and maintenance of species boundaries. The findings highlight the synergistic roles of geographic isolation, dispersal strategies, and historical climate change in shaping and preserving biodiversity on islands.
