“…Also, there are significant differences among close populations for P. greggii [24,51], P. oocarpa, P. patula and P. pseudostrobus [52]. Therefore, transferring germplasm need to consider the patterning of genetic differentiation among populations for adaptive quantitative traits.…”

The strategies for the conservation and sustainable use of forest genetic resources, which are essential for the future adaptation of forest species to changing environments, are also a source of valuable genetic resources for breeding and restoration activities. The first step to define and implement cost-effective strategies is to identify specific priority populations. Mexico, in spite of being characterized by high levels of tree species diversity, mostly lacks a combined strategy for the genetic conservation and use of forest genetic resources. The aims of this work are: (i) to identify areas for gene conservation, and (ii) to propose measures for the conservation and sustainable use of forest genetic resources of four pine species: Pinus greggii Engelm. ex Parl., Pinus oocarpa Schiede ex Schltdl., Pinus patula Schiede ex Schltdl. & Cham. and Pinus pseudostrobus Lindl. To do that, we use the existing information on the distribution, genetic variation and conservation and breeding efforts in Mexico. Overall, 51 areas for establishing genetic conservation units were prioritized and 6 genetic zones for the use of forest genetic resources in breeding and selection of forest reproductive material were identified. The current conservation efforts for the four priority Mexican pines should be improved to satisfy the needs of a national breeding and conservation network.

“…The National Forestry Commission of Mexico states that Pinus oocarpa Schiede ex Schltdl. is arguably the most adaptable to extreme conditions [11], and it is considered a highly adaptative species [12] because of its altitudinal pattern of genetic differentiation of growth [13]. This species is the most resin-producing pine in Mexico [14], and yet, there are no research programmes to propose strategies to increase and make production more efficient.…”

Various spatial modelling methods and tools have been used in ecology and biogeography. The application of these options serves a dual function: first, they offer information about the potential distribution of species to understand the richness and diversity of unassessed areas. Second, spatial modelling methods employ these predictions to select relevant sites to determine natural conservation areas. In this study, we compared three methods for modelling the spatial distribution of Egg-cone Pine (Pinus oocarpa Schiede), an important non-timber pine in Mexico. The final goal is to estimate suitable areas for the conservation and reproduction of superior individuals (plus trees) of P. oocarpa as a conservation strategy outside the known distribution since this species possesses a high ecological and economic value. The model used were a generalised linear model (GLM) as a parametric regression method, random forest (RF) as a machine-learning method, and the MaxEnt model, a standard procedure, implemented using the Kuenm R package. The results suggest that the models used performed well since the AUROC was between 0.95 and 0.98 in all cases. MaxEnt and random forest approaches provided more conservative predictions for the distribution of suitable areas of plus trees of P. oocarpa than the generalised linear model, but the random forest algorithm achieved the best performance. The results of the study allowed the determination of ex situ conservation areas for P. oocarpa plus trees outside of their known distribution.

En México, el estrés hídrico y la mala calidad de planta son algunas de las principales causas de mortalidad en plantaciones. El uso de productos antitranspirantes en especies vegetales ha sido una alternativa para reducir la pérdida de agua ante condiciones de disponibilidad limitada de este recurso. El objetivo del presente estudio consistió en evaluar el efecto de tres productos antitranspirantes (Vapor Gard®, Fitoglass® y Ecofilm®) y dos métodos de aplicación (aspersión e inmersión) en la supervivencia de plantas de Pinus cooperi, P. durangensis y P. engelmannii, a partir de indicadores morfológicos de calidad inicial conocidos. Previo al establecimiento del ensayo, en cada individuo se evaluaron cuatro indicadores morfológicos de calidad, posteriormente se aplicaron los antitranspirantes y se evaluó la supervivencia en campo un mes después. Los resultados indicaron que la calidad de planta fue alta, y que la aplicación de antitranspirantes tuvo efectos significativos en el porcentaje de supervvivencia: P. engelmanni presentó 94 % con Fitoglass® por inmersión, P. cooperi 61 % con Ecofilm® por inmersión, y P. durangensis 58 % con Ecofilm® por aspersión. Se concluye que la aplicación de los antitranspirantes y el método de aplicación aumentan de forma diferenciada la supervivencia inicial en las especies estudiadas.
