Phylogenomics and biogeography of Castanea (chestnut) and Hamamelis (witch-hazel): Choosing between RAD-seq and Hyb-Seq approaches
<p>Target enrichment and RAD-seq are well-established high throughput sequencing technologies that have been increasingly used for phylogenomic studies. Each method has its own pros and cons. The choice between them is a practical issue for plant systematists studying the evolutionary histories of biodiversity of relatively recent origins. However, few studies have compared the congruence and conflict between results from the two methods within the same group of organisms in plants. In this study, we employed RAD-seq and Hyb-Seq of Angiosperm 353 genes in phylogenomic and biogeographic studies of <em>Hamamelis</em> (the witch-hazels) and <em>Castanea </em>(chestnuts), two classic examples exhibiting the well-known eastern Asian (EA)-eastern North American (ENA) disjunct distribution, and compared them side by side. Our results showed congruences in phylogenetic inference and divergence time dating between the two data sets obtained through our customized procedures of library preparation and sequence trimming, although they differed in the number of loci and informative sites, the amount of missing data, and sampling within species. We suggest the selection of the two methods based on fund availability and sampling scale. Our phylogenetic analyses of RAD-seq and Hyb-Seq data resulted in well-resolved species relationships, and ancient introgressions were revealed in both genera by D-statistic test and PhyloNet. Biogeographic analyses including fossil data using total evidence-based dated tree and DEC model, applying specific inter-area dispersal probabilities, revealed a complicated history for each genus, indicating multiple intercontinental dispersals and local extinctions in areas outside of the taxa's modern ranges in both the Paleogene and Neogene. The study demonstrates the importance of including fossil taxa for a more accurate reconstruction of biogeographic histories of taxa to understand the EA and ENA floristic disjunction. Our results support an "out of western North America" migration of <em>Castanea</em> but an "out of Asia" migration of <em>Hamamelis</em> during their initial diversification, and the origins of the EA-ENA disjunction in both genera were results of vicariance.</p>

Data from: High genetic diversity and stable Pleistocene distributional ranges in the widespread Mexican red oak Quercus castanea Née (1801) (Fagaceae)
<p>The Mexican highlands are areas of high biological complexity where taxa of Nearctic and Neotropical origin and different population histories are found. To gain a more detailed view of the evolution of the biota in these regions, it is necessary to evaluate the effects of historical tectonic and climate events on species. Here, we analyzed the phylogeographic structure, historical demographic processes, and the contemporary period, Last Glacial Maximum (LGM) and Last Interglacial (LIG) ecological niche models of Quercus castanea, to infer the historical population dynamics of this oak distributed in the Mexican highlands. A total of 36 populations of Q. castanea were genotyped with seven chloroplast microsatellite loci in four recognized biogeographic provinces of Mexico: the Sierra Madre Occidental (western mountain range), the Central Plateau, the Trans-Mexican Volcanic Belt (TMVB, mountain range crossing central Mexico from west to east) and the Sierra Madre del Sur (SMS, southern mountain range). We obtained standard statistics of genetic diversity and structure and tested for signals of historical demographic expansions. A total of 90 haplotypes were identified and 29 of these haplotypes were restricted to sngle populations. The within-population genetic diversity was high (mean hS = 0.72), and among-population genetic differentiation showed a strong phylogeographic structure (NST = 0.630 > GST = 0.266; P < 0.001). Signals of demographic expansion were identified in the TMVB and the SMS. The ecological niche models suggested a considerable percentage of stable distribution area for the species during the LGM and connectivity between the TMVB and the SMS. High genetic diversity, strong phylogeographic structure and potential distribution models suggest in situ permanence of Q. castanea populations with large effective population sizes. The complex geological and climatic histories of the TMVB help to explain the origin and maintenance of a large proportion of the genetic diversity in this oak species.</p>
