“…The Chihuahuan Desert is home to a great richness of species; for this land in North America, 3382 species are reported, of which 826 are endemic to this region [28]. These species have been classified into different types of vegetation according to their distribution patterns and their interaction with the climate, soil, and relief [1,[28][29][30]. The vegetation types with the greatest distribution in the region are microphyllous desert scrubland, rosetophilous desert scrubland, mezquites, and grasslands [13,30].…”

“…The vegetation types with the greatest distribution in the region are microphyllous desert scrubland, rosetophilous desert scrubland, mezquites, and grasslands [13,30]. Currently, changes in land use, intensive use of species, and drought seem to affect the distribution and abundance of species [28,31,32], especially those that are used for commercial purposes [13], such as sotol.…”

Sotol (Dasylirion leiophyllum) is a shrubby species that grows in the Chihuahuan Desert. Sotol plants are commonly used to produce an alcoholic beverage, also known as “sotol”. A study was carried out to assess the composition and structure of shrubby communities where sotol inhabits in northern Mexico. The importance value index (IVI), diversity indexes, and structural attributes of the sotol community were estimated. Furthermore, a principal component and a cluster analysis were conducted in order to identify possible associations of species along the sotol distribution area. A total of 10,273 plants belonging to 17 families and 46 species were recorded, where the Agave lechuguilla and Tiquilia greggi were the most abundant species. Higher abundances of sotol and higher diversity indexes were observed in hillside areas and eastern aspects. The multivariate analyses revealed five shrubby groups in the distribution area of sotol, which grows in valleys, hillsides, and also on the top of mountains. The main communities found where sotol grows are rosetophyllous, microphyllous, and mesquite communities, and also, in higher altitudes, sotol is associated with oak species. This information is not only useful for a better species knowledge, but also for the protection of shrubby communities where Dasylirion leiophyllum inhabits.

“…Exploration of how seasonality is related to network patterns in highly seasonal systems may help us understand how variation in water availability results in changes in interaction patterns. Located on both sides of the Mexico-USA border, the Chihuahuan desert is the largest warm desert of North America with marked seasonality and an extraordinary species richness of cacti (Zavala-Hurtado & Jiménez, 2020). The northwestern part of this arid region is exceptionally rich in bee species (Minckley & Ascher, 2013) with communities that exhibit great taxonomic turnover between the spring and late-summer seasons (Kazenel et al, 2020).…”

1. The maintenance of interactions between plants and their floral visitors depends on factors such as resource variability, seasonality, and population dynamics. Changes in water availability along with different types and levels of anthropogenic disturbance may influence how plants and pollinators interact, especially in arid environments.2. In a semi-arid area of the southernmost Chihuahuan Desert (Mexico), we surveyed bee-plant interactions in the dry and rainy season at sites that differed in disturbance type. We used a mutualistic network approach to analyse our data.3. We collected 946 bee individuals belonging to 32 bee species, almost a third of the total richness previously reported for Querétaro state. We detected a strong impact of seasonality on the structure of ecological interactions, with more complex and robust interactions among bee and plant species in the rainy season. 4. We did not find statistical support for a relationship among disturbance, nestedness, or niche overlap. We did find disturbance negatively affected plant robustness to secondary extinctions. 5. Four plants: Echinocactus platyacanthus, Opuntia stenopetala, Senna wislizeni var.painteri and Cylindropuntia imbricata comprised the core species that were primarily responsible for the resilience of the bee communities. The following bees conformed the generalist core of species: Diadasia rinconis, Lasioglossum (Dialictus) sp. 1, Apis mellifera, and Augochlorella pomoniella.6. Overall, network nestedness and robustness differed significantly between seasons but not among sites with different levels of disturbance.

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.
