Population Genetics

Hsu, Cheng-Te [1], Chung, Kuo-Fang [1].

Integrating phylogeography and ecological niche model to infer population divergence of Oreomyrrhis (Umberiferae) in Taiwan.

The impact of climate-triggered events, such as the Pleistocene glacial cycle, affects the species distribution directly, especially to the species in the tropical mountains of island. There are three taxa out of 25 Oreomyrrhis species , distributed in upper montane forest in Taiwan , O. involucrata, O. taiwanianaand O. nanhuensis, constructed amonophyletic group in the phylogeny. According to the unclear relationships among these species, we integrate genetic and ecological niche model (ENM) to inferthe impact of the last glacial maximum (LGM) toward population divergence by constructing haplotype network to explore the population structure, and applying (ENM) to build the paleodistribution and current distribution for each species. The predicted results will display the range expansion in LGM and reveal refugia regions nowadays.
