“…Our finding indicates that almost half of the research has been done using coniferous species and broadleaf species. Through the search for suitable tree species, it has been possible to explore previously unstudied geographic areas and research niches, which enable us to broaden the scope of the methods applied in dendroclimatology [10,29,38,44,48,50,51,81,82]. Dr. Sergio Zárate and Mary-Ann Hall for their professional support in revising the English version of the manuscript.…”

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.

“…A pesar de los problemas de crecimiento que presenta P. oocarpa, los resultados de COFECHA indicaron una correlación significativa entre series (r = 0.50; P < 0.01), superando los parámetros estadísticos que dicho programa establece (r = 0.3281, P < 0.01) (Holmes, 1983). Los parámetros estadísticos de esta serie son similares a los reportados para P. oocarpa en el bosque La Primavera, Jalisco (Villanueva et al, 2018) y la Reserva de la Biosfera Sierra de las Minas (RBSM) en Guatemala (Cerano et al, 2008); pero superiores a los parámetros determinados por Szejner (2011) en el sitio Pedernal en Guatemala (Cuadro 2). Estos resultados indican la sensibilidad de P. oocarpa a los cambios ambientales y su potencial para emplearse en el desarrollo de reconstrucciones dendroclimáticas (Fritts, 1976;Delgado, 2000;Grissino-Mayer, 2001).…”

“…Sin embargo, los meses del período estacional inviernoprimavera indican una mayor influencia en el crecimiento. Una respuesta similar del crecimiento de P. oocarpa a la lluvia estacional invierno-primavera, se reportó para el bosque La Primavera en Jalisco (Villanueva et al, 2018). Sin embargo, la respuesta de P. oocarpa es diferente en regiones de Guatemala, donde la mayor influencia en crecimiento ocurre con la precipitación primavera-verano (Cerano et al, 2008;Szejner, 2011).…”

“…En México, P. oocarpa registra una distribución desde el norte hasta el sur del país (Martínez, 1992). A pesar de su amplia distribución, sólo existen un par de referencias sobre el análisis dendroclimático de esta especie, la primera realizada en la región de Los Tuxtlas, Veracruz (Gutiérrez, 2013) y la segunda en el bosque La Primavera en Jalisco (Villanueva et al, 2018). Estudios dendroclimáticos en el sur del país con base en P. oocarpa, son muy limitados.…”

Dendrochronological studies are used to reconstruct some climatic variables; in México these studies have focused on central and northern temperate forests where trees present well defined annual rings. Few studies have been carried out in the southern part of the country where annual ring growth is not easily identified and thus makes cross-dating problematic. We analyzed the dendrochronological potential of Pinus oocarpa Schiede for reconstructing climatic variables in the northwest portion of Lagunas de Montebello, Chiapas. We used a selective sampling approach and collected 65 increment cores from 34 trees. While our samples showed a high frequency of false rings (8 to 60 %), we were able to date 30 samples from 22 trees (46 %) using standard dendrochronological techniques and developed total chronologies for total ring width, earlywood, and latewood for a period of 91 years (1925-2015). We found a significant influence of mean precipitation and mean maximum and minimum temperature over the annual ring growth of P. oocarpa in the period 1961-2004. Our results show that winter-spring precipitation (January-May) was the most important for the species’ annual ring growth. However, we found the highest correlation between spring (March-May) precipitation and the earlywood chronology (r = 0.719, P < 0.05). The earlywood chronology also showed potential for reconstructing minimum temperatures (March to May) (r = 0.732, P < 0.05), while the latewood chronology had the potential for reconstructing the maximum temperature (September to January) (r = 0.714, P < 0.05). These results showed that P. oocarpa can be used to reconstruct climatic variables in the Mexican tropics. We recommend that new areas with older trees should be explored in order to increase the depth of chronologies and reconstruct climate records several centuries into the past.

“…Ya no es únicamente de prevención y combate. Ahora, después de varias investigaciones en México (Villers et al, 2006;Negrete et al, 2008;Jardel et al, 2009;Flores et al, 2010;Ponce et al, 2012;Villanueva et al, 2017;Rodríguez-Trejo et al, 2018;Pantoja et al, 2018;Cerano et al, 2019) se reconoce la importancia del fuego como un factor ecológico en 40 % de los ecosistemas del país, incluidos los bosques de pino (Rodríguez-Trejo, 2008). También se reconoce como un elemento que es parte de las tecnologías tradicionales de los campesinos para su subsistencia.…”

Introduction: The objective of this research is to understand the changes in fire use practices of fire use in two indigenous communities located in Lagunas de Montebello National Park, Chiapas, Mexico, where current public policies implementation on fire use suppression have had severe social and ecological repercussions. The wildfire in 1998 has been considered as a breaking point to the changes and tensions that are happening in the region.Method: We applied 66 semi-structured and in-depth interviews to two rural communities, located inside (Tziscao) and outside (Antela). The topics were about local fire uses and the governmental fire policies incidence over rural communities to understand who they are, where are they and how was the birth of the “Sin fuego”.Results and discussion: The narratives included different interpretation about practices of fire uses, mainly in agriculture activities, where fire uses were more severely criminalised. The fire suppression policy implementation, after 1998’s big wildfire in the Park, marked a before and after in the territory. Generally, these public policies are opposed to the traditional logic in the use of fire, and they have been generating a disappearance of fire use practices in these rural territories, where communities have historically used the fire for several purposes. Some practices that included the use of fire, such as slash and burn agriculture have entirely disappeared in Tziscao, a community where the fire was a central element of culture, livelihood, and a way of building the territory. At present, the inhabitants are afraid to use fire in their practices, due to repercussions for causing fires and the risk of declining tourism. In Antela rural community, which is located outside to the Park and with no economic dependence on tourism, maintains traditional fire practices on farming activities.Conclusion: If the tendency to suppress fire is maintained, not only will a process of cultural transformation intensify, but also of environmental degradation about to the construction of the territory. More significantly, a dramatic modification of the landscape could trigger more catastrophic wildfires. Thus, the long-term challenge is not to make inviable or exclude fire, is to include it in the maintenance and shaping of the landscape based on the experience and knowledge that peasant communities have, the investigation of available fire ecology, and sensibilise and integrate the government authorities for the formulation of fire management plans that integrate local practices.
