Inferring the demographic history of species is fundamental for understanding their responses to past climate/landscape alterations and improving our predictions about the future impacts of the different components of ongoing global change. Estimating the time-frame at which population fragmentation took place is also critical to determine whether such process was shaped by ancient events (e.g. past climate/geological changes) or if, conversely, it was driven by recent human activities (e.g. habitat loss). We employed genomic data (ddRAD-Seq) to determine the factors shaping contemporary patterns of genetic variation in the Iberian cross-backed grasshopper Dociostaurus crassiusculus, an endangered species with limited dispersal capacity and narrow habitat requirements. Our analyses indicate the presence of two ancient lineages and three genetic clusters resulted from historical processes of population fragmentation (~18–126 ka) that predate the Anthropocene. Landscape genetic analyses indicate that the limits of major river basins are the main geographical feature explaining large-scale patterns of genomic differentiation, with no apparent effect of human-driven habitat fragmentation. Overall, our study highlights the importance of detailed phylogeographic, demographic and spatially-explicit landscape analyses to identify evolutionary significant units and determine the relative impact of historical vs. anthropogenic factors on processes of genetic fragmentation in taxa of great conservation concern.

“…On the territory of Siberia and the Far East, this species is listed as rare in the Red Books of the Amur and Jewish Autonomous Regions and the Republic of Sakha (Yakutia) [4, 5,6]. In spite of the available data on the intraspecific genetic differentiation obtained using ISSR markers for the representatives of Cypripedium genus [7,8], the species C. calceolus, C. macranthon and assumed hybrid С. × ventricosum growing in the Novosibirsk Region (NR) have not beens tudied yet.…”

Cypripedium calceolus L. and C. macranthon Sw. (Orchidaceae) are rare species throughout almost the entire territory of Russia. Though the data on intraspecific genetic differentiation has been presented in the literature, the species of C. calceolus, C. macranthon and alleged hybrids of C. × ventricosum growing in sympatric population in the Iskitim District of the Novosibirsk Region (NR) have not been investigated yet. The purpose of this work is dentification of the rare species of Cypripedium calceolus, C. macranthon and detection of C. × ventricosum hybrids in the NR using morphometric parameters and ISSR markers. It was found the mature generative specimens of C. × ventricosum formed the largest number of shoots, compared with the parent species. According to the number of flowers on the generative shoot, the hybrid occupied an intermediate position. According to the ISSR analysis, components from both parental species were identified in each of the three hybrids studied. Therefore, the presence of C. × ventricosum hybrid plants in the local NR coenopopulation of co-growing species C. calceolus and C. macranthon was detected and confirmed based on the study of morphometric parameters and ISSR markers.

“…As hypothesized, Central and Western populations in China harbored relatively higher levels of genetic variation compared to Eastern populations. Further, the former areas served as large LGM refugia for many species in China; mainly boreal and temperate plants [47][48][49]. For this study, Group I and III contained relative genetic diversity among all examined populations ( Table 1).…”

Background: Acer ginnala is a deciduous shrub/small tree that primarily distributed across the northern regions of China. It comprises a foundation species in many terrestrial ecosystems and has significant ornamental and economic value. Owing to its increased use as an economic resource, overexploitation and environmental destruction have resulted in the vulnerability of this species. Thus, the elucidation of the genetic differentiation and influence of environmental factors on A. ginnala is very critical for its management and future utilization strategies. Results: Our results revealed that high genetic variation occurred in A. ginnala species while low genetic diversity was observed at the population level. Most differentiation has found among populations. A significant correlation existed between genetic and environmental distances. Seven climate variables (bio1, bio2, bio3, bio4, bio13, bio15 and bio18) might explain the substantial levels of genetic variation (> 40%) in populations. The most suitable areas of this species appeared in Shaanxi, Shanxi, Anhui Provinces, and Northeastern China based on ENM results. Compared to the last interglacial (LIG) period, A. ginnala migrated toward Northern and Northeastern China, and extended to the most suitable areas during the last glacial maximum (LGM) period. Shanxi and Anhui Provinces might have served as refugium owing to their relatively high genetic variation. Conclusions: Low genetic diversity at the population level that may be the source of its vulnerability. Climate heterogeneity would play an important role in the pattern of genetic differentiation in A. ginnala populations. The A. ginnala population was isolated by a heterogeneous climate and subsequently began to adapt to local selection processes resulted in high genetic divergence.
