“…While many studies have addressed long-term trends in wood density in forests of the Northern Hemisphere [21][22][23], there are few studies in southern latitudes where temperate forests grow [24][25][26]. Retrospective wood density profiles are essential to understand past climate effects on forest ecosystems over temporal and spatial scales.…”

Ongoing climate variability strongly affects high-elevation forests, influencing the wood formation process (e.g., xylogenesis). Furthermore, spatio-temporal studies to establish links of wood properties and tree performance are needed. Using linear mixed-effects models, empirical cumulative distribution functions, and spatial analysis, we explore time trends and space connections of wood density of Pinus hartwegii Lindl. to remotely sensed variables (Moderate Resolution Imaging Spectro-radiometer MODIS-derived) in two high-elevation forests in México, Tláloc (TLA) and Jocotitlán (JOC) Mountains. Results indicated that elevation and cambial age effects are important factors explaining wood density variation. Minimum earlywood—MID, average—AVE, and maximum latewood density—MXD were statistically similar between mountains (p > 0.05), but TLA showed a significant increase in MID over time with higher values after 1950. Wood density values and spatial correlations were site-dependent with TLA exhibiting the highest correlations between MXD and the Normalized Difference Vegetation Index (NDVI) of the spring season (r = 0.59, p < 0.05). Overall, correlations to remotely sensed information were positive with MXD, negative for MID and divergent for AVE. Historical temperature defines MID along the elevation gradient, while MXD was related to soil moisture only at low-elevation sites where soils are deeper. We found that two high-elevation forests, 115 km away from each other, with similar climate, soil, and vegetation, behaved differently regarding their xylogenesis, indicating the potential of using the link between wood micro-density and remotely sensed information to understand forest response to climate change effects.

“…The inclusion of wood density as an indicator of climate variability improves the carbon capture estimates. Several studies carried out in the area have evaluated the responses to climatic conditions (González-Elizondo et al, 2005; González-Cásares, Pompa-García & Camarero, 2017; Pompa-García et al, 2017a), while others have used density for biometric purposes (González-Cásares, Yerena-Yamallel & Pompa-García, 2016; Pompa-García & Venegas-González, 2016). It has also been reported that the wood density of a species ( Abies durangensis ) that coexists with the species evaluated in the present study is more sensitive to temperature than the tree-ring width (González-Cásares, Pompa García & Venegas González, 2018).…”

“…Combined with other methods, the calculation of biomass using growth rings provides more accurate estimations of carbon capture and improves the temporal resolution of periodic forest inventories (Babst et al, 2014c). The use of wood density for estimating biomass improves our understanding of the dynamics of carbon capture in these ecosystems (González-Cásares, Yerena-Yamallel & Pompa-García, 2016; Pompa-García & Venegas-González, 2016; Pompa-García et al, 2018). In general, the results show that low precipitation and high temperatures lead to substantial effect on carbon accumulation over the last 30 years.…”

Background Forest ecosystems are considered among the largest terrestrial carbon sinks. The dynamics of forest carbon depend on where the carbon is stored and its responses to environmental factors, as well as the physiology of the trees. Thus, threatened forest regions with high biodiversity have great scientific importance, such as the Sierra Madre Occidental in Mexico. A comparative analysis of tree species can expand the knowledge of the carbon cycle dynamics and ecological processes in this region. Here, we examined the growth, wood density, and carbon accumulation of two threatened species (Pseudotsuga menziesii and Cupressus lusitanica) to evaluate their hydroclimatic responsiveness. Methods The temporal variations in the carbon accumulation patterns of two co-occurring species (P. menziesii and C. lusitanica) and their sensitivity to the local climate were studied using dendroecological techniques, X-ray densitometry, and allometric equations. Results The results show that the annual carbon accumulation in C. lusitanica is positively associated with the temperature during the current fall, while the carbon accumulation in P. menziesii is correlated with the rainfall during the winter of the previous year. The climatic responses are associated with the intra-annual variations of wood density and ring widths for each species. The ring width was strongly correlated with carbon accumulation in C. lusitanica, while the mean wood density was linked to carbon accumulation in P. menziesii. Discussion This study has implications for the carbon accumulation rates of both species, revealing differences in the carbon capture patterns in response to climatic variations. Although the species coexist, there are variation in the hydroclimatic sensitivity of the annual carbon sequestered by trunks of trees, which would be associated with tree-ring width and/or wood density, i.e., directly by anatomical features. The results are relevant to analyze the response to the variability of climatic conditions expected in the near future of the tree communities of Sierra Madre Occidental. Therefore, this study provides a basis for modeling the long-term carbon budget projections in terrestrial ecosystems in northern Mexico.

“…El cambio climático global es uno de los problemas ecológicos más severos, que se acentúan por el incremento en las emisiones de gases de efecto invernadero (Bolin y Sukumar, 2000). Este fenómeno tendría repercusiones particularmente graves para los ecosistemas naturales, coadyuvando al incremento de problemáticas, tales como el ascenso de la temperatura del aire, el ascenso del nivel medio del mar, el incremento en la evaporación potencial en suelo y cuerpos de agua, deterioro de hábitats, cambios en la distribución geográfica de biomas, sobreexplotación de especies, reducción de áreas boscosas, contaminación de mantos acuíferos, entre otros (Raynal-Villaseñor, 2011;González et al, 2003;Ordóñez, 2008).…”

“…A pesar de ser actualmente fuentes netas de emisión de GEI, los bosques tienen la posibilidad de mitigar GEI a través de la captura de dióxido de carbono (CO 2 ) en diferentes ecosistemas vegetales (sumideros) (González et al, 2016;Ordóñez, 2008;Ordóñez y Masera, 2001). Estos ecosistemas forestales son parte importante en el ciclo global del carbono, ya que en ellos se fija y almacena dicho gas a partir de procesos fotosintéticos; el carbono se almacena principalmente a través del suelo, la vegetación y el matillo, en cuanto al fuste de un solo árbol se almacena el 84 % de biomasa, donde el 46 % es carbono.…”

Los bosques templados de México están bajo fuertes presiones tanto por procesos biológicos como de explotación antrópica, aun si pertenecen a Áreas Naturales Protegidas (ANP’s). Para la evaluación de estos ecosistemas y sus procesos de deterioro no se cuenta con mecanismos de control que garanticen una mejora en su dinámica interna, por tanto, los estudios de ocupación de suelo son imprescindibles para entender dichos procesos, particularmente en el estrato arbóreo, y las funciones de captura y reservorio de carbono (C). Se calculó la biomasa y el contenido de C por hectárea de especies forestales predominantes (Pinus hartwegii, Abies religiosa, Quercus laurina y Alnus jorullensis) con datos representativos de 30 parcelas. Con los datos de densidad de arbolado por hectárea, dominancia de especies, densidad básica de la madera y factor de expansión de biomasa, se estimó el stock de Carbono de cada zona forestal. Se sobrepusieron los mapas de stockde C (2000 y 2013) y se obtuvieron las áreas en donde se presentan procesos de cambio en el stock de C. Los bosques con mayor pérdida de C son: Pinus hartwegii y Abies religiosa.
