“…3) indicates that F. sylvatica populations in this region may be particularly sensitive to future increases in summer drought stress. This was predicted by Broadmeadow et al (2005), and similar results have been reported in Quercus robur L., where growing season drought is a significant climate stress across the species geographical distribution and is not restricted to marginal populations (Drobyshev et al 2008;Rozas 2005). …”

The aim of our study was to determine variation in the response of radial growth in Fagus sylvatica L (European Beech) to climate across the species full geographical distribution and climatic tolerance. We combined new and existing data to build a database of 140 tree-ring chronologies to investigate patterns in growth-climate relationships. Our novel meta-analysis approach has allowed the first investigation of the effect of climate on tree growth across the entire geographical distribution of the species. We identified key climate signals in tree-ring chronologies and then investigated how these varied geographically and according to mean local climate, and by tree age and size. We found that the most important climate variables significantly correlated with growth did not show strong geographical patterns. Growth of trees in the core and at the southern edge of the distribution was reduced by high temperature and low precipitation during the growing season, and by high temperatures in the previous summer. However, growth of trees growing in warmer and drier locations was more frequently significantly correlated with summer precipitation than other populations. Additionally, the growth of older and larger trees was more frequently significantly correlated with previous summer temperature than younger and smaller trees. Trees growing at the south of the species geographical distributions are often considered most at risk from climate change, but our results indicate that radial growth of populations in other areas of the distribution is equally likely to be significantly correlated with summer climate and may also be vulnerable. Additionally, tree-rings from older trees contain particular growth-climate relationships that are rarely found in younger trees. These results have important implications for predicting forest carbon balance, resource use and likely future changes to forest composition across the continent.

“…As for beech, tree-ring growth seems to be mainly driven by early summer weather conditions, as indicated by the large number of predictor variables for such months. This is in accordance with a bundle of European studies that identified soil water availability in early summer as the main growth limiting factor for oak (Kelly et al 2002, Drobyshev et al 2008, Friedrichs et al 2009a, Scharnweber et al 2011). Due to climate change, drought periods are expected to be more frequent in the future (Lindner et al 1997, Grigoryan et al 2010, probably inducing growth reductions of oak in northeastern Germany.…”

“…The quality of the resulting models is also supported by the fact that most of the retained predictor variables have an ecophysiological meaning. The dominance of variables representing data of June and July of the growing year illustrates the importance of early summer weather conditions, the period of maximum ring growth, for radial increments of all three tree species (Lebourgeois et al 2005, Drobyshev et al 2008, Friedrichs et al 2009a). In addition, the frequent occurrence of previous years' parameters illustrates the importance of preceding weather conditions such as severe drought periods for tree growth (Scharnweber et al 2011).…”

Tree growth depends, among other factors, largely on the prevailing climatic conditions. Therefore, changes to tree growth patterns are to be expected under climate change. Here, we analyze the tree-ring growth response of three major European tree species to projected future climate across a climatic (mostly precipitation) gradient in northeastern Germany. We used monthly data for temperature, precipitation, and the standardized precipitation evapotranspiration index (SPEI) over multiple time scales (1, 3, 6, 12, and 24 months) to construct models of tree-ring growth for Scots pine (Pinus sylvestris L.) at three pure stands, and for common beech (Fagus sylvatica L.) and pedunculate oak (Quercus robur L.) at three mature mixed stands. The regression models were derived using a two-step approach based on partial least squares regression (PLSR) to extract potentially well explaining variables followed by ordinary least squares regression (OLSR) to consolidate the models to the least number of variables while retaining high explanatory power. The stability of the models was tested through a comprehensive calibration-verification scheme. All models were successfully verified with R²s ranging from 0.21 for the western pine stand to 0.62 for the beech stand in the east. For growth prediction, climate data forecasted until 2100 by the regional climate model WETTREG2010 based on the A1B Intergovernmental Panel on Climate Change (IPCC) emission scenario was used. For beech and oak, growth rates will likely decrease until the end of the 21 st century. For pine, modeled growth trends vary and range from a slight growth increase to a weak decrease in growth rates. The climatic gradient across the study area will possibly affect the future growth of oak with larger growth reductions towards the drier east. For beech, site-specific adaptations seem to override the influence of the climatic gradient. We conclude that Scots pine has great potential to remain resilient to projected climate change without any greater impairment, whereas common beech and pedunculate oak will likely face lesser growth under the expected warmer and dryer climate conditions. The results call for an adaptation of forest management to mitigate the negative effects of climate change for beech and oak.

“…Lebourgeois et al, 2004). Water requirements during the summer are typical of deciduous oaks even in environments that are considerably wetter than those we studied (Čufar et al, 2008;Drobyshev et al, 2008;Friedrichs et al, 2009;Helama et al, 2009;Lebourgeois, 2006;Tardif et al, 2006). Stem age and logging history affect decadal tree productivity response to climate (e.g.…”

Abstract• We combined stem volume increment analysis with dendroecological tools to address two unresolved issues concerning oak dieback in Mediterranean areas: early detection of changes in stand growth, and identification of mechanisms for observed growth declines.• We reconstructed productivity of a stored coppice formed by Turkey oak (Quercus cerris) to test if its growth decline was linked to climatic variability, while also accounting for age-related and sociological factors.
