“…In Mexico, there are few taxonomists specialized in the identification of grasses. However, in the last decade, researchers from INECOL have delved into the classification of these species with the support of molecular markers, so their study is based on phylogenetic relationships [18,70,73,74].…”

Arid and semi-arid areas are highly productive ecosystems that have a great diversity of species, among which grasses stand out. These species have ecological, environmental, and economic importance. The objective was to identify the ecological descriptors of 15 native species of grasses and diversity patterns through multivariate analysis techniques (principal component analysis, PCA, and cluster analysis, CA), in addition to identifying potential distribution areas (current and future) and regions of high and low diversity from 3841 accessions and 21 climatic variables. Among the main results, the extreme values, coefficient of variation, and median for each species could be determined. PCA determined that, with 10 variables, it was possible to explain 54.36% of the variation between the analyzed species. CA resulted in the formation of four statistically significant groups, with specific climatic characteristics. Regarding potential distribution areas and climate change, a reduction in distribution is expected (2050) on most of the current surface, with a possible opportunity zone in the north of the country. Finally, two hotspots (high diversity areas) and four coldspots (low diversity areas) were identified among the analyzed species. These results can be used to create strategies for sustainable use and the conservation of these resources.

“…However, most of the restoration projects with blue grama in Mexico have been performed using seed imported from the USA, which may be a factor limiting the establishment of this species. For this reason, several breeding programs have been performed to select outstanding genotypes of this species, which may be employed to restore degraded grasslands [ 17 , 18 , 19 , 20 ]. Nevertheless, these selection programs have been mainly focused on agronomic traits, such as high biomass production, while the genetic structures and environmental niches of the selected genotypes have not been considered as selection factors.…”

“…This grass has been widely used due to its proven adaptability to a wide range of environmental conditions and its high forage quality [ 16 , 17 ]. In the past years, several breeding programs have been performed to select outstanding genotypes of this species that may be employed to restore degraded grasslands [ 17 , 18 , 19 , 20 ]. These selection programs have mainly focused on agronomic traits, such as high biomass production, while the genetic structures and environmental niches of the selected genotypes have not been considered as selection factors.…”

Understanding the genetic structure adopted by natural populations and its relation to environmental adaptation is critical for the success of restoration programs. We evaluated the genetic structure and temporal environmental niche dynamics of blue grama (Bouteloua gracilis) in 48 populations. The genetic evaluation was performed through amplified fragment length polymorphism (AFLP) molecular markers. The maximum entropy method was used to model the past, present, and future environmental niches of the three clusters derived from the genetic analysis. The environmental niches of the three genetic clusters showed dynamic overlaps and isolations during the last interglacial and glacial maximum. The paleoclimatic events, which occurred during those periods, may have reinforced genetic exchange among populations and affected their genetic structure. Genetic clusters also presented different environmental niches in the present. Thus, they can be considered as three distinct ecotypes and restoration programs must be carried out using local germplasm from each environmental niche to increase their chance of success. Based on the environmental niches of the genetic clusters, changes are expected in the near and mid-century future. Therefore, climate change must be considered for species conservation management and future restoration programs.

“…Respecto al pasto navajita, se ha encontrado una gran diversidad genética dentro de esta especie (62) , lo cual puede deberse a que el centro de origen de esta especie se encuentra en el centro de México (63) . Así mismo, existe la posibilidad de seleccionar germoplasma de pasto navajita de alta producción, ya que de sólo 145 ecotipos colectados en Chihuahua, se reportó un rango de rendimiento desde 0.3 hasta 48 g MS planta -1 en un solo corte (64) .…”

El objetivo fue revisar el estado actual de los pastizales semiáridos y matorrales áridos del norte y centro de México, así como analizar los retos y perspectivas del uso de estos ecosistemas. Desde la década de los años 1950, el INIFAP en colaboración con otras instituciones han generado y transferido conocimientos sobre manejo de pastizales, lo cual se ha reflejado en el uso de prácticas de manejo en los ranchos ganaderos del país. Los pastizales y matorrales han sufrido disturbios, principalmente la apertura de tierras para cultivos y se encuentran deteriorados principalmente por el sobrepastoreo. La utilización de los pastizales y matorrales a través del pastoreo debería incluir una carga animal adecuada, sistemas de pastoreo y prácticas estratégicas de distribución del pastoreo. A pesar del deterioro, existe una gran diversidad de recursos genéticos, principalmente de pastos, que pueden ser utilizados para conservación y producción de semilla para rehabilitación de los pastizales. La resiembra, aunque de alto costo y riesgo, es una opción para rehabilitar aquellos pastizales o matorrales deteriorados. Estos ecosistemas pueden proporcionar servicios ambientales, principalmente captura de carbono para mitigar el cambio climático. Los retos son generar, transferir y aplicar conocimientos e innovaciones tecnológicas para lograr un manejo sostenible de los pastizales y matorrales, a pesar de algunas amenazas como la baja inversión en ciencia y tecnología, el cambio climático y la avaricia humana. Para lograr esto, es imprescindible la participación conjunta y comprometida de todos los actores e instituciones involucrados en el uso de estos ecosistemas.
