abstract = {The climate-growth response of specific sites and species
is one of the main research subjects in classic tree ring
studies. Traditional sampling approaches therefore aim at
maximizing the climate signal of the analyzed tree ring
series, which is typically achieved by focusing on dominant
trees or on sites located in particularly temperature or
moisture limited environments. However, there is increasing
evidence that these selective sampling strategies cannot
yield chronologies that are representative for entire
populations. One promising approach to gain a deeper
understanding of forest dynamics and climate-growth
responsiveness is the analysis of climate signal ranges
among trees. This individualistic approach requires random
sampling and the integration of information on small-scale
heterogeneities in site and tree characteristics. Here, we
analyze the climate-growth response of 144 Norway spruce
trees (Picea abies Karst.) on difference levels of data
aggregation. The aim of our study is to investigate the
relevance of small-scale heterogeneities in site conditions,
particularly in soil water supply, for the detected
climate-growth signal. We identify soil water supply and
site characteristics, which indirectly modify the water
availability for trees, as dominating growth factors across
scales. The driest sites show the strongest climate-growth
reaction, while the growth response of wetter sites is weak
or even insignificant. Therefore, we conclude that
integrating small-scale information on site characteristics,
particularly on soil water supply, can help to gain a deeper
understanding of species specific growth limitations.},
