“…Estas forman poblaciones y comunidades forestales altamente diversas (INEGI, 2010;Astudillo et al, 2017) contribuyendo así a la existencia de abundante variabilidad genética de especies de animales y plantas. Pinus hartwegii en particular posee bajos niveles de diversidad genética que podrían contribuir al ataque de descortezadores (Heredia-Bobadilla et al, 2012;Heredia-Bobadilla et al, 2016;Sunny et al, 2019). Sin embargo, a pesar de tratarse de dos ANPs, el deterioro en ambas regiones es constante, siendo la tala clandestina, el cambio de uso de suelo, la sobreexplotación de los mantos hídricos y los incendios forestales las perturbaciones antrópicas más comunes (Arriola-Padilla et al, 2015).…”

El descortezador Dendroctonus adjunctus Blandford, 1897, es una especie parásita de los bosques de Pinus hartwegii y sus poblaciones van en aumento, esto implica una amenaza para esta especie de pino. En este trabajo se determinó la distribución espacial de D. adjunctus en dos áreas naturales protegidas del centro de México. Se establecieron 1,621 unidades de muestreo (UM) en 12,924 ha de bosque de pino en el Área de Protección de Flora y Fauna Nevado de Toluca (APFFNT) y 634 UM en 10,008 ha de Monte Tláloc (MT). Se registraron las características dendrométricas de todos los árboles ≥ 7.5 cm de DAP, así como el nivel de infestación del hospedero y la presencia de plantas parásitas. El 19 % del total de sitios muestreados presentan infestación por el descortezador en altitudes de 3,600 a 3,900 m y categorías diamétricas de 30 a 55 cm. La distribución espacial de los descortezadores está influenciada por la exposición, altitud, pendiente y la presencia simultánea con muérdagos enanos (Arceuhtobium spp.).

“…For example, Aguirre-Planter et al (2000) identified a relationship between gene flow and geographic distances in TVB populations based on isoenzymes. Heredia-Bobadilla et al (2012) reported a high genetic variability between populations and low levels of gene flow in populations inhabiting the Nevado de Toluca National Park, using chloroplast DNA (cpDNA; cp-trnK, cp-TRNG-trnQ) and mitochondrial DNA (mtDNA; nad-5, coz3in). Also, Jaramillo-Correa et al (2008), through mtDNA and cpDNA, revealed that the Mesoamerican Abies species share a recent common ancestor and that their divergence and speciation have been determined mainly by genetic drift and isolation during warm interglacial periods.…”

Genetic structure of a population can be molded by the resistance of the landscape or the distance between populations that function as barriers to gene flow. We analyzed the population genetic structure of Abies religiosa on a fine spatial scale and examined isolation models by resistance and distance. We collected vegetative tissue from populations located at the altitudinal extremes of the distribution range of the species on three slopes of La Malinche National Park (LMNP) (South, North, and East) in central Mexico. Genomic DNA was obtained using the CTAB 2X method, and eight microsatellite chloroplast loci were amplified. The genetic structure was identified based on an Analysis of Molecular Variance, a Discriminant Analysis of Principal Components with cross-validation and a spatial Principal Component Analysis using the Gabriel-type connectivity network. The isolation hypotheses were evaluated by constructing partial Mantel tests using Reciprocal Causal Modeling and Maximum Likelihood Population Effects models. A genetic structure of isolation by resistance to elevation was identified, and two genetic groups were recognized: one including populations of the South slope and the other comprising populations of the North and East slopes. We detected in Abies religiosa populations of the LMNP an isolation by resistance to elevation that determines the genetic structure, and the greatest genetic exchange between groups of populations located at higher altitudes. It is suggested to promote the connectivity between slopes through assisted migration and immediately halt land-use changes, as part of the actions to preserve genetic diversity in the LMPN. This study contributes to the knowledge of the spatial genetic structure of species at risk in the Mexican temperate forest for their conservation.

“…The TMVB region encloses a large number of natural protected areas (NPA), the Protection of Flora and Fauna Area Nevado de Toluca (PFFANT) is one of them. The closeness of this NPA to large cities entails environmental pressures that includes the presence of human settlements, illegal logging, introduction of exotic species and the growing incidence of forest parasites like bark beetles and dwarf mistletoes [1][2][3].…”

Mountain pine (Pinus hartwegii Lindl) is one of the most abundant conifers in the Protection of Flora and Fauna Area Nevado de Toluca in central Mexico; this natural protected area is threatened by urbanization; this has been manifested in forest health; there has been an increase in forest parasites like bark beetles and dwarf mistletoes, making necessary improve forest management and conservation, hence our objective was to study the genetic diversity of mountain pine under the attack of parasites and to generate information that could be used to improve strategies of conservation of these forests. We classified sampled trees into four categories according to the type of parasite present in a tree (bark beetle: BB; dwarf mistletoe: DM; bark beetle and dwarf mistletoe: BM and non-attacked trees or healthy trees: HT). Genetic diversity was low in comparison with other pine species, but we observed an interesting issue: trees attacked by bark beetle and dwarf mistletoe had higher levels of heterozygosis: He nc = 0.1924 and He nc = 0.1993, respectively. These results suggest that trees with bark beetle and dwarf mistletoes may have higher genetic variability and are a highly valuable genetic resource for mountain pine.
