“…However, the spatial coverage of long tree-ring records must be improved to allow a better understanding of regional variations in past climate (1,2). For example, in eastern North America, millennial climate reconstructions have been constructed from tree species and sites sensitive to drought and precipitation (3), whereas temperatures were inferred solely from low-resolution proxies, such as pollen data (4,5). Furthermore, only tree-ringbased climate reconstructions shorter than a millennium or using chronologies poorly replicated before A.D. 1500 have been published for the entire North American boreal forest (6,7), whereas several millennial, highly replicated, temperature-sensitive treering records have been developed across the Eurasian boreal zone.…”

Significance The cooling effect on the Earth's climate system of sulfate aerosols injected into the stratosphere by large volcanic eruptions remains a topic of debate. While some simulation and field data show that these effects are short-term (less than about 10 years), other evidence suggests that large and successive eruptions can lead to the onset of cooling episodes that can persist over several decades when sustained by consequent sea ice/ocean feedbacks. Here, we present a new network of millennial tree-ring chronologies suitable for temperature reconstructions from northeastern North America where no similar records are available, and we show that during the last millennium, persistent shifts toward lower average temperatures in this region coincide with series of large eruptions.

“…Taxodium mucronatum tolera condiciones de sequía en ciertos períodos, en especial, durante la fase de i nactivi dad fisiol ógica, pero su carencia en la estación de crecimiento no puede prolongarse por varios años consecutivos, situación que provocaría su muerte en menos de tres años de falta total de agua. Aunque pudiese sobrevivir por la lluvia, la humedad residual en el lecho del río, porque algunas de sus raíces alcanzan sitios con disponibilidad de humedad (Stahle et al, 1985;Villanueva et al, 2007;Stahle et al, 2012).…”

RESUMENEl estudio se realizó en un transecto con sabinos muertos en el río San Pedro-Mezquital, con el objetivo de determinar el impacto de la construcción de presas en el crecimiento radial anual del arbolado, en respuesta al desfasamiento y disminución de los volúmenes de agua. Árboles muertos y vivos de la especie de interés se muestrearon en una extensión de un kilómetro con más de 300 individuos muertos; a partir de árboles en pie se obtuvieron virutas con un barreno. Un muestreo similar se realizó en otro sitio aledaño, pero con individuos vivos. Las muestras se fecharon con técnicas dendrocronológicas estándar, y se generaron dos cronologías con fines comparativos: una de organismos muertos y otra de vivos. Se determinó que la mayoría de los ejemplares murieron en 1991 (el último anillo completo fue 1990) y otros más entre 1992 y 2003. Se detectaron diferencias en crecimiento entre los índices de la cronología con árboles vivos y muertos en fecha posterior al funcionamiento de la presa Guadalupe Victoria, en 1962. Las causas de la mortandad involucran una combinación de factores: la disminución y desfasamiento del caudal, debido al confinamiento del agua en las represas Guadalupe Victoria y Santiago Bayacora, esta última construida en 1989; la ubicación del arbolado lejos del cauce principal; una sequía intensa en 1989 y la desviación del cauce hacia parcelas agrícolas. La información generada permite cuantificar el impacto de las presas en el crecimiento radial del sabino, especie dominante en algunos bosques de galería del norte de México.Palabras clave: Arbolado muerto, bosque de galería, caudal, dendrocronología, presas, sequía. ABSTRACTThe study was carried out in a transect with dead cypress trees along the San Pedro-Mezquital river with the aim to determine the impact of dam building on the annual radial growth of cypress trees due to a decrease and to a diphase on the streamflow. Dead and alive cypress trees were selected along a transect of one kilometer length with over 300 dead trees and increment cores were obtained at breast height with an i ncrement borer, a si mi lar sampli ng procedure was i mplemented i n a nearby transect but with alive trees. I ncrement cores were prepared and dated following standard dendrochronological techniques and two ring width series were developed for comparison purposes. Most of the death trees died in 1991(last complete ring was formed in 1990) and a few more between 1992 and 2003. Differences in growth between the tree-ring series were observed after the building of the Guadalupe Victoria dam in 1962. A combination of variables could have caused cypress mortality, such as a decrease in the streamflow due to its storage in the Guadalupe Victoria and Santiago Bayacora reservoirs, this last built in 1989, location of cypress tress far away from the main stream, a severe dry year occurred in 1989, and diversion of the streamflow for irrigation purposes. The results allow us to improve our knowledge on the effect of dams on annual radial growth of cypress trees a ...

Capturing season‐specific precipitation signals in the northern Rocky Mountains, USA, using earlywood and latewood tree rings

Douglas-fir (Pseudotsuga menziesii Mirb. Franco) total width, earlywood, and latewood tree ring chronologies were developed from six lower forest border sites in the northern Rocky Mountain region of central Idaho and southwestern Montana, USA, to assess the potential for season-specific moisture reconstructions. These long-lived arid-site trees share strong between-tree and between-site coherence, and subannual tree ring chronologies reliably span the past seven centuries. Mapping spatiotemporal patterns in northern Rocky Mountain precipitation highlighted winter-and summer-dominated precipitation regimes that transition along a west to east gradient. When Douglas-fir tree rings were compared with instrumental climate records, season-specific correlations emerged between earlywood and latewood. Total width, earlywood, and latewood shared the most statistically significant monthly correlations with April-June precipitation, whereas variability in adjusted latewood was tuned to June-August precipitation. Principal component analysis indicated that the leading mode of common variance for earlywood and adjusted latewood explained 65% and 55% variance in the chronologies, respectively. Pearson's correlations between earlywood principal component one and the northern Rocky Mountain precipitation field showed that annual (July-June) and spring (April-June) precipitation exhibited the strongest pattern of significance in central Idaho and southwestern Montana valleys and the Snake River Plain. Summer precipitation (June-August) was correlated with adjusted latewood principal component one and was particularly pronounced along and east of the continental divide in southwestern Montana. These results indicate that Douglas-fir earlywood and adjusted latewood tree rings in the northern Rocky Mountains retain season-specific precipitation signals and may be helpful for studying historical precipitation within the winter-summer transition zone.
