Speciation and subsequent secondary contact in two edaphic endemic primroses driven by Pleistocene climatic oscillation.

ABSTRACT: Climatic perturbation during the Pleistocene era has played a major role in plant evolutionary history by altering species distribution range. However, the relative roles of climatic and geographic factors in the distribution dynamics remain poorly understood; in particular, the edaphic endemics. In this paper, we examine the evolutionary history of two ultramafic primroses, Primula hidakana and Primula takedana. These species are ecologically and morphologically distinct with disjunct distributions on Hokkaido Island, Japan. Primula hidakana is found on various rocks in southern Hokkaido and P. takedana in serpentine areas in northern Hokkaido. We performed population genetics analyses on nuclear and chloroplast data sets and tested alternative phylogenetic models of divergence using appr
