“…It has been recorded that oak populations in Mexico have low to slightly high levels of genetic differentiation (Albarrán‐Lara et al, 2018; González‐Rodríguez, Arias, & Oyama, 2005; Maldonado‐López et al, 2014). This concurs with our results: Q. laurina displayed low levels of genetic differentiation, whereas Q. calophylla and Q. rugosa exhibited slightly higher levels, and indicates that there is little genetic differentiation in the studied populations, denoting presence of gene flow and absence of genetic isolation among them (Wang, Wei, Lu, Chen, & Wang, 2014).…”

Firewood and charcoal are used on a daily basis both in rural areas and in cities. This type of energy is produced by one of the most ancient traditional methods, known as coppice, which harvest tree sprouts. There is controversy about its effects on forests: it preserves populations and tree cover of species used, but reduces density, inhibits sexual reproduction and generates genetic erosion. We inquired if it was possible to identify a loss of genetic diversity in oak populations traditionally used for charcoal by the Zongolica Nahuas in Veracruz state, Mexico. We studied populations of Quercus laurina, Quercus calophylla and Quercus rugosa in three different altitudes. Molecular analysis with eight nuclear codominant microsatellites was performed to determine the diversity, structure and gene flow of these species. Results for Q.

“…However, there are a few studies on the genetic diversity of Q. liaotungensis populations. Only Qin studied the genetic diversity of eight natural Q. liaotungensis populations from the Shanxi Province using 11 SSR primer pairs (Qin et al, 2012), andWang et al (2014) studied the genetic diversity of 8 Q. liaotungensis populations from the Shanxi Province at different altitudes using SRAP markers. The sampling strategy in a similar distribution incompletely assessed the genetic diversity of Q. liaotungensis with previous studies.…”

Background Quercus liaotungensis Koidz. is an ecologically and economically important tree species widely distributed in Northern China. However, the effective assessment, utilization, and protection of Q. liaotungensis resources remain unexplored. Methods In total, 120 samples obtained from 12 Q. liaotungensis populations of Northern China were investigated for genetic diversity and structure using 19 simple sequence repeat (SSR) primer pairs. Results The total number of alleles detected was 293, the average number of effective allele (Ne) was 6.084, the genetic differentiation coefficient (Fst) was 0.033, and the mean observed heterozygosity (Ho) and expected heterozygosity (He) were 0.690 and 0.801, respectively. Moreover, analysis of molecular variance (AMOVA) showed a 5.5% genetic variation among 12 Q. liaotungensis populations, indicating that a high level of genetic diversity and a low degree of genetic differentiation among Q. liaotungensis populations. STRUCTURE and cluster analysis divided the 12 Q. liaotungensis populations into the following three subpopulations: Bashang Plateau subpopulation (SH), Liaodong Peninsula subpopulation (NC), and Loess Plateau subpopulation (other 10 populations). The cluster analysis based on 19 climatic factors was consistent with the genetic structure. A positive correlation was found between genetic distance and geographical distance (r = 0.638, p = 0.028) by the Mantel test, and two boundaries were found among the 12 Q. liaotungensis populations by the Barrier analysis, indicating that Q. liaotungensis populations existed isolated by geographical distance and physical barrier. Conclusion This study suggests that geographical isolation, physical barrier, climatic types, and natural hybridization promote the formation of genetic structures, which can contribute to future protection and genetic improvement of Q. liaotungensis.
