Parallel phylogeography of mountain endemics: do infrageneric species share geographic history?

The Hengduan Mountains region of southwest China is a temperate biodiversity hotspot characterized by high rates of plant endemism, including approximately 300 endemic species of Pedicularis (Orobanchaceae). Many factors have likely contributed to high rates of speciation in this genus, including isolation and migration in a heterogeneous landscape, as well as species interactions and character displacement. Although many species occur as very narrow endemics, several species have very large geographic ranges across which they often exhibit substantial morphological variation. This provides an opportunity to examine the process of population divergence and speciation in action, and investigate replicated histories to ask whether species show parallel phylogeographic patterns. Here I share results of spatial population genomic analyses from hundreds of densely sampled populations across 12 widespread species of Pedicularis generated by RADseq.
