“…In contrast, the sensitivity of spruce growth to summer droughts could be observed since approximately the 1950s (Eckstein and Krause 1989;Neumann 2001;Piovesan et al 2003;Wilmking et al 2005;Dobbertin and Giuggiola 2006). The future warming might therefore prove favourable for growth of European beech compared to Norway spruce.…”

It is believed that European beech (Fagus sylvatica L.) will increase its competitive ability at its northern range margin in Scandinavia due to climate change. In mixed old-growth forests of beech and Norway spruce (Picea abies (L.) Karst.) at Siggaboda nature reserve (southern Sweden), stand structure characteristics were sequentially recorded in the years 2004, 2005 and 2007 as well as growth in stem diameter using tree-coring analyses. Using these measurements, we studied the effects on stand dynamics of an extreme storm event (2005 ''Gudrun'' hurricane), drought and heat (mid-summer 2006, spring 2007) and subsequent bark beetle attacks on spruce (growing season 2007), overlaid with warming tendencies. The storm, which caused disastrous damage in many stands nearby, had comparatively little impact on the structure of the spruce-beech stand. All together, only 32 trees (19 spruces, 10 beeches, 3 other species) per hectare were thrown or broken mainly in the leeward direction (NE) or impacted by secondary damage by uprooted neighbour trees; this represents 7% of the total tree number and 11% of the growing stock. Diameter and height structure did not change significantly. However, the 2006 drought and the 2007 attack of biotic agents changed the stand structure and composition strongly due to the death of about 19% of the dominating older spruce trees that accounted for 35% of total stand volume. This resulted in a considerable increase in beech's contribution to stem number (4% increase) and wood volume of the living stand (7% increase). A comparison of diameter growth of beech and spruce during the periods 1894-1949 and 1950-2005 showed a distinct decrease in growth superiority of spruce during the last 50 years. These results support the idea of a northward migration of European beech as a nemoral tree species in Sweden, due to a higher tolerance to the abiotic and biotic threats accompanying climate change and an increased competitive ability compared to boreal tree species Norway spruce.

“…Esta sincronización entre series individuales fue expresada como una correlación entre árboles, varianza en el primer vector propio y relación señal-ruido mayores que en las cronologías de roble. Sin embargo, los valores obtenidos se encuentran dentro del rango de variabilidad habitual para el haya (Gutiérrez, 1988;Dittmar et al, 2003;Piovesan et al, 2003), y en ambas especies los valores de correlación entre árboles se encuentran dentro del rango de variabilidad esperado para frondosas caducifolias (Pederson et al, 2004). Las correlaciones entre cronologías evidencian una notable similitud en los patrones de variabilidad del crecimiento a dos niveles principales.…”

ResumenEn este trabajo se analizaron las respuestas climáticas de tres cronologías de haya (Fagus sylvatica L.) y tres de roble (Quercus robur L.) en la región central de la Cornisa Cantábrica. Se utilizaron datos climáticos regionales y el índice de Oscilación del Atlántico Norte (NAO) como indicativo de la señal macroclimática. Las cronologías presentaron una variabilidad interanual similar entre especies y localidades. Las correlaciones mayores y más extensas en el tiempo se obtuvieron entre cronologías de la misma especie y similar altitud. Las cronologías presentaron señales de distinta frecuencia coincidentes con señales características de los índices NAO. El 52-64% de la variación del crecimiento fue explicada por el clima regional, mientras que la NAO explicó un 13-27%. La elevada temperatura estival del año previo al crecimiento y la baja temperatura invernal fueron factores limitantes para el haya por encima de 700 m de altitud. El crecimiento del roble a baja altitud estuvo limitado por la elevada temperatura primaveral del año previo y por la sequía estival del año de crecimiento. Ambas especies mostraron una relación negativa con los índices NAO invernales, del año previo al crecimiento en el haya y del mismo año de crecimiento en el roble. En el roble se manifestó además una relación negativa con la NAO de final del verano del año previo. Estos resultados sugieren la necesidad de investigaciones más extensas sobre la caracterización del crecimiento radial y su respuesta climática a lo largo de la Cornisa Cantábrica.Palabras clave: anillos de crecimiento, dendrocronología, análisis espectral, respuesta climática, clima regional, NAO. Abstract Characterization and analysis of climatic signal in chronologies of Fagus sylvatica L. and Quercus robur L. in the central Cantabrian region, SpainIn this work, the climatic responses of three beech (Fagus sylvatica L.) and three oak (Quercus robur L.) tree-ring chronologies in the central Cantabrian region, were analyzed. Regional temperature and precipitation data, and the climatic teleconnection indices of the North Atlantic Oscillation (NAO), were used as climatic predictors. Very similar interannual ring-width variability among chronologies of different species and localities was displayed. Chronologies of the same species and similar altitudes showed the highest cross-correlations, which were significant at widest timescales. Periodic signals of a variety of frequencies that coincided with signals characteristic of NAO indices, were discovered in the chronologies. Between 52 to 64% of growth variance was explained by regional climate, while 13 to 27% was related to monthly NAO indices. High summer temperatures in the year prior to ring formation and low winter temperatures limited beech growth at altitudes over 700 m. Oak radial growth at lower altitudes was limited by high spring temperatures in the previous year and summer drought in the year the ring was formed. Growth of both species displayed negative relationship with winter NAO indices, in the prev...

“…The decrease of T min with altitude during the days of late frosts is plotted as a regression line. Altitudinal belts potentially affected by late frost impacts are highlighted by an arrow 1981; Ko¨nig and Mayer 1988;Reif and Papp-Vary 1995;Piovesan et al 2003). Especially strong signals in tree rings were found if late frosts occurred in two subsequent years (1927/1928, 1941/1942, 1952/1953, and 1968/1969).…”

Impact of late frost events on radial growth of common beech (Fagus sylvatica L.) in Southern Germany

Phenological, temperature, and tree-ring data were used in order to identify and quantify the impact of late frosts on common beech (Fagus sylvatica L.) at different altitudes in Southern Germany during the last century. For this intention, dendroecological investigations were made upon trees at the Meteorological Observatory Hohenpeißenberg as well as from seven stands in the Bavarian Forest and 17 stands at the northern fringe of the Alps. From these locations, a considerable number of severe growth minima in the tree-ring series could be related to late frost in the days of or immediately after leaf unfolding. The frequency of frost-related growth minima increases with altitude. In individual years, radial growth can be reduced by more than 90% (stand mean) in relation to the average growth of the ten previous years. Hence, late frosts are considered as important ecological events that strongly affect beech vitality and competitiveness especially at high altitudes. Evidence of significant impacts on radial growth by late frosts distinct before leaf unfolding or with temperatures above À3°C was not found. Also, increasing frequency and intensity of late frosts during recent decades were not ascertained. Hence, the recently observed decreased vitality of common beech accompanied by growth depressions especially at high altitude sites in Central Europe cannot be explained as a consequence of late frost damage.
