“…Studies at neighboring sites on similar species have demonstrated the positive influence of a wet and cool climate during this period on the growth of trees [31,34]. The conditions experienced by the trees during the previous winter are precursors of soil mixture during the early season of growth in spring, and determine the available water or the amount of reserves (e.g., carbohydrates, nutrients) accumulated at the beginning of the growth period [17,48]. This influence prior to the beginning of tree-ring formation could become more relevant due to the presence of warmer and drier winters, putting some forests in higher decline risks [25].…”

“…In addition, these forests are major water sources used to supply agriculture in Sinaloa, Nayarit, and Coahuila [34]. The Sierra Madre Occidental is also an important and valuable source of ecosystem services for local populations [17], and it is a strategically important region for studies in the conservation and biodiversity of conifer forest ecosystems.…”

“…These instrumental climatic data were obtained monthly from the two nearest climatic seasons: El Salto (period 1946-2015) and Otinapa (period 1962-2015) [40]. The correlation analysis window was from June of the previous year to September of the growing year, based on previous dendroclimatic analyses in the study area [17,25]. To estimate drought severity and duration we used the standardized precipitation evapotranspiration index (SPEI) [41], as this index considers the effects of temperature on evapotranspiration rates on water availability and it quantifies the intensity of drought at different time scales.…”

“…To investigate the factors responsible for the temporal and spatial response patterns of forests to drought, elevation or precipitation gradients have been used as a surrogate of climate gradients [16,17]. Along with these gradients, radial growth (usually measured as changes in tree-ring width) varies in response to changes in water deficiency [5,18], site conditions [19], and tree characteristics (e.g., tree size, age, dominance, or vigor) [20,21].…”

Drought is a major constraint of forest productivity and tree growth across diverse habitat types. In this study, we investigated the drought responses of four conifer species growing within two locations of differing elevation and climatic conditions in northern Mexico. Two species were selected at a mesic site (Cupressus lusitanica Mill., Abies durangensis Martínez) and the other two species were sampled at a xeric site (Pinus engelmannii Carr., Pinus cembroides Zucc.). Using a dendrochronological approach, we correlated the radial-growth series of each species and the climatic variables. All study species positively responded to wet-cool conditions during winter and spring. Despite the close proximity of species at a mesic site, A. durangensis had high responsiveness to hydroclimatic variability, but C. lusitanica was not responsive. At the xeric site, P. engelmannii and P. cembroides were very responsive to drought severity, differentiated only by the longer time scale of the response to accumulated drought of P. engelmannii. The responsiveness to hydroclimate and drought of these tree species seems to be modulated by site conditions, or by the functional features of each species that are still little explored. These findings indicate that differentiating between mesic and xeric habitats is a too coarse approach in diverse forests with a high topographic heterogeneity.

“…Tree-ring samples were collected from five sampling locations within the study area for growth evaluation. Using standard dendrochronological techniques, local tree-ring chronologies (TRI) were generated (Pompa-García et al, 2013a), which were taken as representatives of the common climate signal for the site.…”

RESUMENLa Oscilación del Sur El Niño (ENSO, por sus siglas en inglés) es el principal fenómeno de circulación de gran escala que ocasiona variabilidad climática en el norte de México. El desafío actual consiste en entender sus consecuencias para los procesos climáticos y ecológicos de los ecosistemas. En este contexto, se comparó el grado de asociación de tres diferentes índices de ENSO con la precipitación local (P) en el norte de México, y se utilizaron series dendrocronológicas (cronologías de anillos de crecimiento [TRI, por su siglas en inglés]) de Pinus cooperi para valorar su impacto en el crecimiento forestal. Los resultados mostraron un asociación importante entre ENSO, la precipitación del invierno anterior y el TRI (r > 0.5, p = 0.05), lo cual indica que hay una relación directa entre las fases cálidas de ENSO y el crecimiento de los árboles. El índice multivariado de ENSO explicó ligeramente mejor que otros índices la conexión entre P y el crecimiento radial. Estos resultados pueden apoyar futuras investigaciones sobre los efectos de ENSO en el clima local y los ecosistemas forestales. ABSTRACTEl Niño Southern Oscillation (ENSO) is the most important large-scale circulatory phenomenon that causes climatic variability in northern Mexico. The current challenge is to understand its consequences for both local climate and ecological processes of ecosystems. Within this context, we compared the degree of association of three different ENSO indices with local seasonal precipitation (P) in northern Mexico, and used dendrochronological series (tree-ring chronologies [TRI]) of Pinus cooperi to assess the impact of forest growth. The results showed a strong association between ENSO, previous winter precipitation and TRI (r > 0.5, p = 0.05), indicating a positive relationship between warm ENSO phases and subsequent tree growth. The multivariate ENSO index was slightly better at explaining the connection between P and radial growth than other indices. These results could be used to support further research on the effects of ENSO on local climate and forest ecosystems.
