High-frequency variation of Norway spruce radial increment [Picea abies (L.) Karst.] and its dependence on various climatic variables was compared in stands across latitudinal and altitudinal transects in southwestern and eastern Germany, Norway, and Finland. The tested variables included local temperature and precipitation, northern hemisphere temperature(More)
For Central Europe, climate projections foresee an increase in temperature combined with decreasing summer precipitation, resulting in drier conditions during the growing season. This might negatively affect forest growth, especially at sites that are already water-limited, i.e., at low elevation. At higher altitudes trees might profit from increasing(More)
Anticipated changes in climate and research findings on the drought sensitivity of beech have triggered controversial discussions about the future of European beech. We investigated the growth response of beech on the treeand stand-level in mature stands to three different thinning intensities (no thinning, strong thinning, very strong thinning) on a(More)
The objective of the study was to introduce a simultaneous approach to extracting growth trends from diameter increment series by combining tree- and stand-level information in the framework of mixed-effects modeling. The model results are compared with those of the sequential modeling approach according to Yue et al. Can J For Res 41:1577–1589, (2011).(More)
A useful approach to monitor tree response to climate change and environmental extremes is the recording of long-term time series of stem radial variations obtained with precision dendrometers. Here, we study the impact of environmental stress on seasonal growth dynamics and productivity of yellow birch (Betula alleghaniensis Britton) and sugar maple (Acer(More)
The importance of European beech (Fagus sylvatica L.) for the Central European forest and wood sector demands profound research to examine the adaptive capacity of beech forests to changing environmental conditions. Quantitative wood anatomy is a valuable tool for studying the relation between structural and functional traits of trees, but due to the(More)
Time series are time stamped sequences of values which represent a pa rameter of the observed processes in subsequent time points Given a set of time series describing a set of similar processes the model of the behavior of processes is constructed as a range of classi cation trees which describe the characteristics of each particular time point in series(More)
European beech (Fagus sylvatica L.) is one of the economically most important broadleaved tree species in Central Europe. However, beech shows high drought sensitivity and calls for profound research to test its ability to cope with limited water resources. Here, we investigated the drought tolerance of beech to the 2003 drought as influenced by Kraft(More)
