Abstract:The existence of endangered tree species in Mexico necessitates an understanding of their vulnerability to the predicted climate changes (warming and drying trends). In this study, the sensitivity to climate of earlywood (EW) and latewood (LW) widths of the threatened Picea chihuahuana was determined. The response of EW and LW to climate variables (maximum temperature, minimum temperature, precipitation, evaporation, and a drought index) was analyzed by means of correlation analysis using dendrochronology over the period of 1950-2015. EW and LW production were enhanced by cool and wet conditions during winter prior to the start of growing season. During the growing season, EW and LW production increased in response to cool spring and summer conditions, respectively; temperatures and year-round evaporation, excluding summer and the previous drought in the period prior to the growing season. EW was sensitive to seasonal drought, which is a concern considering the predicted aridification trends for the study area. These results provide further knowledge on the dendroecological potential of Picea chihuahuana.

Is There a Response Pattern between Radial Growth of Trees and Elevation Gradient?

et al. 2023

Improving our understanding of the growth dynamics of trees along elevation gradients could help us predict their potential to store carbon and their vulnerability to changes in local and global environmental conditions, such as deforestation and climate change. This study is a review and analysis of the results obtained in recent dendrochronological studies of the effect of elevation and climate (temperature and precipitation) on the radial growth of trees in temperate zones, mainly in the Northern Hemisphere. Only 18 (32.1%) of the 56 studies analyzed found a correlation between radial growth of the trees (total chronologies) and elevation. The analysis of 56 chronologies of 46 tree species included in the 110 works reviewed, showed that only in 28.2% of them the correlation between radial growth versus temperature and precipitation was significant: positive in 3.6%, negative in 2.7%, and positive and negative in 21.8%, depending on the season of the year. The wide variation found in the radial growth response of the trees to elevation gradients may be related to multiple environmental factors at a local or regional scale, but also to the different sampling methods used in the studies. However, a moderate proportion of the studies analyzed (close to 30%) show that temperature and rainfall are related to trends in radial growth in different elevation ranges and regions of the world.

Esto permite estudiar respuestas y patrones en escalas temporales y espaciales amplias, que de otra manera demandarían un seguimiento prolongado en el tiempo y a escalas espaciales menores (Amoroso and Suárez 2015).…”

Variación en los patrones de crecimiento previo a la muerte de individuos de Austrocedrus chilensis a lo largo de un gradiente pluviométrico en el norte de la Patagonia Andina

R��. Los bosques Andino-Patagónicos albergan una de las coníferas endémicas de América del Sur: Austrocedrus chilensis (D. Don) Pic. Ser. et Bizzarri (Cupressaceae). El hecho de que ocurran eventos episódicos de mortalidad a lo largo del gradiente de distribución de la especie hace necesarios estudios que echen luz sobre el comportamiento de los árboles en tales eventos. El objetivo de este trabajo fue estudiar los patrones de crecimiento previo a la muerte de individuos de Austrocedrus chilensis en un gradiente de precipitación O-E. El área comprende la distribución septentrional de la especie en el norte de la Patagonia argentina. Se seleccionaron nueve sitios de muestreo a lo largo de una transecta O-E en las cercanías del Lago Traful, provincia de Neuquén. La transecta abarca un gradiente de precipitación entre 1800 y 600 mm/año. Se analizaron patrones y tasas de crecimiento en los 5, 10 y 15 años previos a la muerte a lo largo del gradiente. Los resultados permitieron establecer que, según la variabilidad de los patrones de crecimiento, los sitios analizados se ordenaron en dos grandes grupos según el tipo de bosque: mixtos-compactos y compactos-ecotonales. A su vez, estas diferencias se relacionaron con condiciones particulares de las cronologías (e.g., el índice de ancho de anillo) y biofísicas (e.g., pendiente, exposición, latitud y longitud) de los sitios de estudio. Las tasas de crecimiento previas a la muerte permitieron determinar que, en todos los sitios de estudio, los individuos presentaron una disminución en el crecimiento radial previo a este evento; a su vez, para iguales ventanas temporales, los individuos muertos crecieron menos que los individuos vivos. En base a estos resultados, es necesario profundizar los estudios para conocer los mecanismos por los que se ordenan estos patrones de crecimiento previo a la muerte a lo largo del gradiente Andino-Patagónico.[Palabras clave: mortalidad, gradiente de precipitación] A��. Variation in the growth pa�erns prior to death of individuals of Austrocedrus chilensis along a pluviometric gradient in the North of Andean Patagonia. The Andean-Patagonian forests are home to one of the endemic conifers of South America: Austrocedrus chilensis (D. Don) Pic. Ser. Et Bizzarri (Cupressaceae). The occurrence of episodic mortality events along the gradient of distribution of this species makes necessary studies to shed light on allow advance on the responses of trees to these tree behaviors in these events. The objective of this research is to study of the growth pa�erns prior to the death of individuals of Austrocedrus chilensis in a W-E precipitation gradient. Specifically, the area includes the northern distribution of the species in northern Patagonia, Argentina. Nine sampling sites were selected along a west-east transect in the vicinity of Traful Lake, Neuquén province, which captures a precipitation gradient of 1800 to 600 mm/year. Pa�erns and growth rates were analyzed in the 5, 10 and 15 years prior to death along the gradient. The results obtain...
