“…However, the evidence of already ongoing forest decline likely due to climatic change, including defoliation due to drought stress, low tree vigor, and forest insect and pathogen attacks contributing to extensive tree death (Alfaro et al 2014), in Mexico is perceived in diverse ways. For example, emphasis is placed on climatic variability (such as the El Niño -Southern Oscillation (ENSO)) as a main driver behind forest pest outbreaks, although not necessarily linked to climatic change (Cervantes-Martínez et al 2019). Thus, it is our impression that, in the Mexican forest management community, there is no consensus attributing such forest decline to ongoing climatic change.…”

Symptoms of forest decline, apparently due to climate change, have become evident in the last 10 years on the Trans-Mexican Volcanic Belt and northwestern temperate forest of Mexico, particularly at the xeric (low elevational) limit of several forest tree species. We review and provide recent evidence of massive infestation of timberline Pinus hartwegii Lindl. by the mistletoes Arceuthobium globosum Hawksw. & Wiens and Arceuthobium vaginatum (Humb. & Bonpl. ex Willd.) J.Presl; insufficient Abies religiosa (Kunth) Schltdl. & Cham. seedling recruitment at the Monarch Butterfly Biosphere Reserve; indications of inbreeding and defoliation in endangered Picea chihuahuana Martínez, Picea martinezii T.F. Patt., Picea mexicana Martínez, and extreme southern populations of Pseudotsuga menziesii (Mirb.) Franco; and the incidence of unusual pest and disease outbreaks (e.g., Dendroctonus Erichson, 1836 spp., Neodiprion autumnalis Smith, and Phytophthora cinnamomi Rands) in several conifer and oak species. We also discuss a difficult question: Is natural genetic variation sufficient to provide populations with the adaptive variation necessary to survive the natural selection imposed by projected climate change scenarios, or will phenotypic plasticity be exhausted and populations decline? Controversial ex situ conservation within natural protected areas, assisted migration, and translocation of species ensembles are discussed as options by which to accommodate projected climatic change impacts on the management and conservation practices of the megadiverse Mexican temperate forest.

“…En promedio, para el periodo 1878-2012, el IAB de AA y ANA fue similar (AA=10.5±0.16 cm 2 año -1 , ANA=9.86±0.14 cm 2 año -1 ). Sin embargo, en las últimas décadas las condiciones de sequía han propiciado estrés fisiológico de los árboles en forma gradual, con brotes epidémicos a una escala geográfica mayor (Cervantes-Martínez et al, 2019;Stahle et al, 2020); especialmente a partir de 1998, cuando se observó un crecimiento diferenciado entre AA y ANA (Figura 3B).…”

Las plagas forestales representan una de las principales causas de disturbio en los bosques templados de México. Ips confusus ataca a Pinus cembroides después de intensas sequías. El objetivo del presente estudio fue evaluar tanto el impacto por I. confusus, como del clima en el crecimiento radial de un bosque de P. cembroides en el municipio Carichí, Chihuahua, México. Se obtuvieron núcleos de crecimiento de árboles atacados (AA) y de no atacados (ANA) de la misma especie. Se dataron 53 series dendrocronológicas con una extensión máxima de 1776 a 2012 (AA=24 y ANA=29). A partir de 1998, se observó un crecimiento diferencial en el área basal entre AA y ANA. Al momento de la muerte del arbolado (2012), se registró una diferencia de más de 100 % (AA=8.03±1.53 cm2 año-1, y ANA=17.7±1.74 cm2 año-1, p<0.001). Los ANA mostraron una sensibilidad superior a variables climáticas que los AA, con una mayor sincronía en los últimos años. A nivel dosel, se determinó una correlación con el Índice de Vegetación de Diferencia Normalizada (NDVI, r=0.51, p<0.05) exclusivamente para ANA. Sin embargo, los AA fueron más sensibles a condiciones de sequía, con base en el Índice de Severidad de Sequia de Palmer (PDSI, r=0.53, p<0.05). Esto sugiere que condiciones de sequía previas (hasta 10 años) predisponen menor crecimiento radial de P. cembroides y favorece el ataque de plagas.

Dendroclimatology has gained relevance during the XXI century. We analyze the state of-the-art of dendroclimatology in Latin America during the past 28 years (1990 to 2019), identifying the current state and recent advances in the application of dendroclimatology in this region. We carried out a systematic review in ScienceDirect, Web of Science, and Scopus databases using Boolean operators to logically connect the keywords “dendrochronology,” “dendroclimatology,” “trend,” “climatic variability,” and “climatic variability trend”, for each country. Dendroclimatological research conducted in the region focused on climatic reconstruction and the evaluation of new tree species with dendrochronological potential, which increase in 2010, then there was a gap between 1995 and 1996, later increase to present. Dendroclimatological studies in Latin America have been mainly developed in temperate climate zones (82.4 %) followed by tropical or subtropical areas (17.6 %). Dendroclimatological research in Latin America has provided advances in the study of climate variability by defining response functions of tree rings to climate. The generated information allows for a better understanding of the spatial and temporal dynamics of climatic variability and about its effects on ecosystems and society. We also call for increased dendroclimatological research based on subtropical and tropical forests limited studied until today.
