“…The structured phylogeographic pattern between the ChD and SMO that we detected has been reported in several desert scrub plant species from the ChD (e.g., Sosa et al, 2009;Scheinvar et al, 2017;Vásquez-Cruz & Sosa, 2016). In all cases, a strong phylogeographic structure found within the SMO was correlated with Ephedra compacta and Agave lechuguilla (Loera et al, 2017;Scheinvar et al, 2017) can be explained by an initial expansion, followed by processes of isolation between lineages.…”

“…In all cases, a strong phylogeographic structure found within the SMO was correlated with geologic and paleoclimatic changes. As an example of this pattern, Vásquez‐Cruz & Sosa (2016) identified a main phylogeographic pattern in species of Rosaceae where the ChD was the ancestral area, followed by contraction of suitable habitat during the Last Interglacial (~120,000–140,000 years), then an expansion during the LGM (~22,000 years) to the SMO and the Central Mexican Plateau and finally recolonization of the ChD during the Mid‐Holocene (~6000 years). Loera et al (2017) argued that this structured pattern between SMO and ChD in Ephedra compacta was reinforced by the lack of dispersal and changes in elevation due to biogeographic barriers within this region.…”

Climate changes, together with geographical barriers imposed by the Sierra Madre Oriental and the Chihuahuan Desert, have shaped the genetic diversity and spatial distribution of different species in northern Mexico. Pinus pinceana Gordon & Glend. tolerates extremely arid conditions. Northern Mexico became more arid during the Quaternary, modifying ecological communities. Here, we try to identify the processes underlying the demographic history of P. pinceana and characterize its genetic diversity using 3100 SNPs from genotyping by sequencing 90 adult individuals from 10 natural populations covering the species' entire geographic distribution. We inferred its population history and contrasted possible demographic scenarios of divergence that modeled the genetic diversity present in this restricted pinyon pine; in support, the past distribution was reconstructed using climate from the Last Glacial Maximum (LGM, 22 kya). We inferred that P. pinceana diverged into two lineages ~2.49 Ma (95% CI 3.28–1.62), colonizing two regions: the Sierra Madre Oriental (SMO) and the Chihuahuan Desert (ChD). Our results of population genomic analyses reveal the presence of heterozygous SNPs in all populations. In addition, low migration rates across regions are probably related to glacial–interglacial cycles, followed by the gradual aridification of the Chihuahuan Desert during the Holocene.

“…Protocols for extraction, amplification and sequencing including the DNA markers with their corresponding primers are the same utilized in previous research (Gándara & Sosa, 2014; Loera, Ickert-Bond & Sosa, 2017). For the three remaining species we used previously published sequences ( B. trifoliolata : Angulo et al, 2017, Lindleya mespiloides : Vásquez-Cruz & Sosa, 2016; S. caeruleus : Hernández-Hernández, Colorado & Sosa, 2013) (Fig. 1; see Table 1 for localities).…”

Background Deserts are biologically rich habitats with a vast array of animals and plants adapted to xeric conditions, and most deserts are among the planet’s last remaining areas of total wilderness. Among North American deserts, the Chihuahuan Desert has the highest levels of diversity and endemism. To understand the effect of future climate change on plants distributed in this arid land and propose effective conservation planning, we focused on five endemic shrubby species that characterize the Chihuahuan Desert and used an integrative approach. Methods Ecological niche-based modeling, spatial genetics and ecological resistance analyses were carried out to identify the effect of global warming on the studied five shrubby species. Key areas that need to be preserved were identified taking into account the existing protected areas within the Chihuahuan Desert. Results The extent of future distribution will vary among these species, and on average expansion will occur in the western part of the Chihuahuan Desert. For most species low environmental resistance to gene flow was predicted, while higher future resistance was predicted for one species that would lead to increased population isolation. The highest haplotype diversity was identified in three hotspots. Based on future suitability of habitat and in the haplotype diversity we suggest preserving two hotspots of genetic diversity in the Sierra Madre Oriental, located in areas without protection. The third hotspot was detected in the well preserved Tehuacán-Cuicatlán Man and Biosphere Reserve. Conclusion Global climate change will have an effect in arid adapted plants, favoring expansion in the western of the Chihuahuan Desert however negatively affecting others with high ecological resistance disrupting gene flow. Two hotspots of genetic diversity in the Sierra Madre Oriental should be protected.
