“…La reconstrucción de la precipitación para la región de San Dimas, Durango, se fundamentó en el crecimiento anual como variable independiente, cuya formación está relacionada significativamente (r = 0,73, P < 0,01) con la precipitación invierno-primavera. Una explicación a esta respuesta es, que los inviernos más húmedos contribuyen a un mejor proceso de fotosíntesis en la estación cálida y, por tanto, en mayor crecimiento de los árboles (Kerhoulas et al 2013). Las lluvias en invierno suelen ser de baja intensidad, lo que favorece la infiltración, saturación del suelo y una baja evapotranspiración, resultando en un balance hídrico positivo que es empleado por el árbol al inicio de la estación de crecimiento (Fritts 2001).…”

SUMMARYThe studies on reconstruction of paleoclimatic series play an important role in analyzing regional climate variability when instrumental information is not available. Tree-ring samples from stands of Pinus durangensis, Pinus cooperi and Pinus lumholtzii were used to generate chronologies in order to reconstruct and analyze the historical hydroclimatic variability for the region of San Dimas, Durango, Mexico. A principal component analysis (PCA) indicates that those series showed a common variability; subsequently, a regional series was developed covering a period of 294 years. An analysis of response function suggests that the most important climate variable influencing tree growth was the seasonal winter-spring precipitation (January-June), which accounted for 52 % of the variability. Reconstruction of the variability of the winter-spring precipitation for the last three centuries was possible. Such a profile allowed us to identify important drought periods (1740-1746, 1766-1780, 1785-1786, 1819-1824, 1890-1900, 1935-1940, 1950-1957 and 2011-2015). Because of their extension, the periods 1766-1780, 1890-1900 and 1950-1957 were the longest. Based on historical records, four events of severe drought (1785-1786, 1935-1940, 1891-1902 and 1950) were associated with strong havoc in central Mexico and their effects were extended to northern Mexico. In addition, a wavelet coherence analysis suggests a strong relationship between the reconstructed precipitation (Winter-Spring) and NIÑO 3 SST (December to February) in phase from 1770 to 1978 with frequencies from 1 to 5 years, ENSO has significantly modulated climate variability in this region of the state of Durango.Key words: chronologies, reconstructed precipitation, drought, ENSO. RESUMENLos estudios de reconstrucción de series paleoclimáticas juegan un papel importante para analizar la variabilidad del clima regional cuando no se dispone de información instrumental. Muestras de anillos de árboles de rodales de Pinus durangensis, Pinus cooperi y Pinus lumholtzii fueron empleados para generar cronologías con el objetivo de reconstruir y analizar la variabilidad hidroclimática histórica para la región de San Dimas, Durango, México. Un análisis de componentes principales (PCA) determinó que las series presentan variabilidad común, se desarrolló una serie regional de 294 años. Un análisis de función de respuesta mostró que la variable climática que más ha influido en el crecimiento es la precipitación estacional invierno-primavera (enero-junio), que explicó el 52 % de la variabilidad. Se logró reconstruir la lluvia invierno-primavera para los últimos tres siglos. Esta reconstrucción permitió identificar importantes periodos de sequía (1740-1746, 1766-1780, 1785-1786, 1819-1824, 1890-1900, 1935-1940, 1950-1957 y 2011-2015), por su extensión destacaron los periodos 1766-1780, 1890-1900 y 1950-1957. Con base en archivos históricos, se corroboraron cuatro eventos de sequía severa (1785-1786, 1935-1940, 1891-1902 y la década de 1950) que propiciaron fuertes estrago...

“…Winter precipitation from northern Pacific systems falls during periods of low evaporative demand and therefore penetrates deep into the soil, while late summer monsoon precipitation derived from subtropical eastern Pacific and Gulf of Mexico air masses occurs as short, intense events when evaporation is high [21,22]. These conditions largely restrict infiltration of monsoon precipitation to upper soil layers [23,24]. Winter and summer precipitation inputs have distinct isotopic signatures, with winter precipitation being more depleted in the heavier isotopes ( 2 H and 18 O) than summer precipitation [25].…”

“…Winter and summer precipitation inputs have distinct isotopic signatures, with winter precipitation being more depleted in the heavier isotopes ( 2 H and 18 O) than summer precipitation [25]. The combination of greater infiltration by the isotopically more depleted winter precipitation and greater evaporative enrichment of isotopically heavier summer precipitation creates an isotopic gradient from heavier to lighter with increasing soil depth [24,26,27].…”

“…Stable isotope analysis of water in precipitation, soil, and plant stems is commonly used to study plant reliance on seasonal precipitation [7,21,22,24,[27][28][29]. Stable isotope analysis of alpha cellulose can also identify seasonal water sources and integrates water use over a longer time period than stem water analyses [30][31][32][33].…”

Abstract:The North American Monsoon delivers warm season precipitation to much of the southwestern United States, yet the importance of this water source for forested ecosystems in the region is not well understood. While it is widely accepted that trees in southwestern forests use winter precipitation for earlywood production, the extent to which summer (monsoon season) precipitation supports latewood production is unclear. We used tree ring records, local climate data, and stable isotope analyses (δ 18 O) of water and cellulose to examine the importance of monsoon precipitation for latewood production in mature ponderosa pine (Pinus ponderosa Dougl.) in northern Arizona. Our analyses identified monsoon season vapor pressure deficit (VPD) and Palmer Drought Severity Index (PDSI) as significant effects on latewood growth, together explaining 39% of latewood ring width variation. Stem water and cellulose δ 18 O analyses suggest that monsoon precipitation was not directly used for latewood growth. Our findings suggest that mature ponderosa pines in this region utilize winter precipitation for growth throughout the entire year. The influence of monsoon precipitation on growth is indirect and mediated by its effect on atmospheric moisture stress (VPD). Together, summer VPD and antecedent soil moisture conditions have a strong influence on latewood growth.

“…For example, trees in stands with higher densities are thinner and absorb more superficial water, by which they start to compete, in view of the smaller amount of available water in this horizon of the ground. While trees in lower density have thicker stem and the roots can capture deeper water [4]. In agroforestry systems, which are production systems that combine crops and trees, the number of trees is reduced relative to that of the forest.…”
