“…Of particular importance in forest biogeocenoses now are the issues of protecting pine stands from pathogens and phytophagous insects. Global climate change makes research on the biological stability and productivity of Scots pine stands relevant, especially in the context of investigating outbreaks of mass reproduction of xylophagous insects and fungal associations, which is confirmed by the presence of a number of publications (Davydenko et al, 2017;Meshkova & Borysenko, 2018;Gómez-Pineda et al, 2022). Ustskyi (2011) found that the period 2001-2006 was characterised by a significant deterioration in the sanitary condition of forest stands of Ukraine and scots pine, in particular, the area of pine stands in which pathological processes were recorded, as of 2006, compared with the records as of 1994 and 1997, increased by 1.3-1.4 times, therefore, a steady trend of deterioration of the sanitary condition was also traced in the monitoring observations of the presented study of pine stands in the Boyarka Forestry Research Station.…”

“…Davydenko et al, 2017, Meshkova & Borysenko, 2018, Meshkova et al, 2017, noted that earlier pathological processes were mainly inherent in ripening stands at the age of more than 80 years, now rapid drying is observed in young and middle-aged stands. Consequently, the decline in the resistance of Scots pine to the effects of stress factors associated with climate change, and the mass spread of the populations of xylophagous insects caused a large-scale drying of coniferous forests and Scots pine, in particular, in most European countries, where over the past decade it has been registered in Poland, Italy, Germany, and in the Scandinavian countries -Finland and Sweden (Gómez- Pineda et al, 2022;Batllori et al, 2022;Pineau et al, 2017). According to the scientific publications of European researchers (Hajek et al, 2022;Batllori et al, 2022), the leading role in the weakening of stands and the formation of foci of mass reproduction of harmful insects is played by unfavourable changes in weather and climatic conditions, among which the main role belongs to the level of moisture and temperature regime.…”

The drying up of coniferous forests is a problem for both Europe and Ukraine, where drying area of pine stands covered the Polissia region and spread to other natural areas, therefore, the analysis of pathological factors of the reasons for the weakening and deterioration of the sanitary condition is relevant. The purpose of the study provides for generalisation of the reasons for the deterioration of the sanitary condition of pine stands and pathological processes in dynamics over 30 years. The results are based on data from 12 permanent and 10 temporary sample plots established in a separate subdivision of the National University of Life and Environmental Sciences of Ukraine “Boyarka Forestry Research Station”. The study used empirical and systematic methods. The predominance of drying of pine stands due to infection with the pathogen Heterobasidion annosum ((F.) Bref.) was revealed, at the same time, with the highest infestation coefficient, the dominant species in the stands under study were ash bark beetles Tomicus piniperda L. (54%), Tomicus minor Hartig (46%) with high and medium infestation rates and Monochamus galloprovincialis Olivier with a tree population ratio of 52% and an average degree of population in trunk areas with transitional and rough bark. In the dynamics of observations since 2011, an increase in the index of sanitary condition of pine stands and deterioration of forests due to changes in weather conditions and climate aridity have been established. After the dry growing seasons of 2015-2017, the drying of pine trees with mass reproduction of stem pests was revealed, the infestation coefficient of which indicates the dominance of the sharp-dentated bark beetle Ips acuminatus Gyll. and a large ash bark beetle Tomicus minor which are aggressive species. Since 2019, there has been a decrease in the number of bark beetles due to exceeding the long-term precipitation rate due to a decrease in the temperature at the beginning of the growing season and unfavourable weather conditions for wintering of these insect species. The results obtained would become an informational component in the development of a strategy for managing damaged forest areas

“…Bark-beetle (Dendroctonus spp., Coleoptera) neotropical pine outbreaks exemplify how multifactorial interactions magnify species decline. Drought events may weaken and increase the vulnerability to the bark beetle in Pinus pseudostrobus trees (Gómez-Pineda et al, 2022). Temperature increases might account for south displacements of this insect, augmenting its distribution area (Armendáriz, 2012).…”

Three upheavals shaped southern Mexico to Panama (SMP) biodiversity: 1. The Great American Interchange that allowed migrations between the Neotropical and the Nearctic biogeographic realms; 2. human colonization with the generation of Mesoamerican cultures; and 3. the Spaniards’ arrival and globalization.Tectonic events generated a narrow piece of land with steep topography and high environmental heterogeneity, demanding high levels of local adaptation. Habitat size is usually restricted and reduced by frequent disturbances. Topography imposes few options for individuals forced to displace. Thus, extinction risks should be unusually high. Humans initiated an ongoing defaunation process and introduced the maize and the milpa, an itinerant maize-based slash-and-burn polyculture, which depends on revegetation to re-establish soil fertility. Also, the milpa is a most important pre-Hispanic legacy, a biocultural and landrace reservoir actively affecting landscape configuration, succession, soil development, and the genetic architecture of the species. Unprecedented human epidemics and soil, biodiversity, and culture erosion followed behind the Spanish aftermath and the subsequent globalization. > 63 million people and ≈100 ethnic groups inhabit SMP in 2020, which, with the biota, share the same problems of climate change, disturbance, and acculturation. SMP has been the scenario of severe climate change, fastest and deadliest extinction events (amphibians), a most spectacular exotic-species invasion (Africanized honeybees), and accelerated deforestation, defaunation, and acculturation. Biocultural conflicts between native and non-native people are globalization byproducts and sources of habitat destruction and species decline. Bottom-up initiatives are likely the best option for conservation in indigenous areas, whereas honest (i.e., with truly conservation intentions) top-down initiatives are helpful if the affected people are considered subjects (no objects) of conservation plans. We suggest some unique areas requiring conservation attention and analyzed current conservation initiatives. Not a single initiative is best suited for all conservation needs in SMP. Protection of all successional stages is critical for resilience and revegetation. Conservation of the milpa system (crop fields and subsequent fallows) is an optimal option for minimizing tradeoffs between conservation and people needs and safeguarding traditional culture and local landraces but is limited to areas with indigenous people and may not work for species with large home ranges.

“…One of the main threats to sacred fir forests is climate change, because it will induce a decoupling between their populations and the climate suitable for them (Gómez-Pineda et al, 2020;Sáenz-Romero et al, 2012), which in turn will lead to increasing incidence of bark beetles, as high temperatures provide favorable conditions for the development of these insects (Gómez-Pineda et al, 2022;López-Gómez, Arriola Padilla, & Pérez Miranda, 2015;Rubin-Aguirre et al, 2015;Sosa Díaz et al, 2018).…”

“…Una de las principales amenazas para los bosques de oyamel es el cambio climático, ya que inducirá un desacoplamiento entre sus poblaciones y el clima propicio para ellas (Gómez-Pineda et al, 2020;Sáenz-Romero et al, 2012), lo que a su vez provocará incidencia cada vez mayor de descortezadores, pues las temperaturas altas proveen condiciones favorables para el desarrollo de estos insectos (Gómez-Pineda et al, 2022;López-Gómez, Arriola Padilla, & Pérez Miranda, 2015;Rubin-Aguirre et al, 2015;Sosa Díaz et al, 2018).…”

Introduction: A species’ populations differ across its distribution due to selection pressure from the climate gradient. Objective: To describe the phytochemical variation among 14 tree provenances in an altitudinal gradient of Abies religiosa (Kunth) Schltdl. & Cham. to determine if there are associations of chemical profiles among populations, expressed under a single environment. Materials and methods: Seeds were collected from 165 trees from an altitudinal transect from 2 850 to 3 540 m in Cerro San Andrés, Municipio Libre de Hidalgo, Michoacán, Mexico. The plant was grown in a common garden trial; at 28 months, mature needles were collected per tree and analyzed by gas-mass chromatography. Data were analyzed with diversity indices, ANOVA and multivariate analysis (principal components, correspondences and cluster). Results and discussion: Thirty-two compounds were identified, most of them terpenes. The populations showed differences in presence/absence of terpenes and in their concentration; above 3 350 m, diversity was lower, but with higher concentration. Three altitude groups were found based on the chemical profile of the populations: low = 2 850 to 3 300 m and 3 400 m; moderate = 3 350, 3 450 and 3 500 m; and high= 3 540 m. Conclusions: The diversity and concentration of terpenes in A. religiosa varied depending on the altitude of populations. There are three chemical profiles that should be considered in the implementation of germplasm collection programs for reforestation and restoration
