<p>New technologies, such as satellites and sensors, provide a wealth of new information about all ecosystems. In dendrochronological studies, all drought-related factors are of great importance for a more comprehensive understanding of associations between radial growth and water loss. Soil moisture directly reflects the wetness of immediate root surroundings, which is vital to the water uptake by trees. Owing to the advances in satellite observation systems and sensors, soil moisture (SM) can be remotely measured, opening new window in dendrochronological research.</p><p>Using the pedunculate oak (Quercus robur L.) lowland SE Europe forests dataset, which count 23 stands and more than 300 tree ring width (TRW) series, we observed reliable associations between satellite-based SM and TRW. Specifically, we observed different TRW−SM patterns based on the precipitation regime. SM in the hottest months (July and August) boosted radial growth, whereas opposite results were noted in the wettest spring months oaks that growing in wetter stands. Unlike oaks from drier and wetter stands that exhibited strong response to SM, those growing on moderately wet (optimal) stands are less sensitive to SM, making these stands optimal oak surroundings.</p><p>On the other hand, by applying a Generalized Additive Mixed Model (GAMM), we noted moderate−weak interactions between TRW series and smoothed SM timescales, with stronger deviations in extreme dry/wet years. Based on the TRW sensitivity to SM findings, which were interpreted via Pearson’s correlation technique and GAMM modeling, strong relations can be inferred, and SM can be labelled as reliable pedunculate oak driver.</p><p><strong>Keywords:</strong> Forestry, Remote sensing, Dendrochronology, Soil moisture, Pedunculate oak, GAMM</p><p><strong>Acknowledgments:</strong> This research was supported by the Science Fund of the Republic of Serbia, PROMIS, #6066697, TreeVita.</p><p><strong>Note:</strong> This contribution is a summary of a study by Kostić S, Wagner W, Orlović S, Levanič T, Zlatanov T, Goršić E, Kesić L, Matović B, Tsvetanov N, Stojanović DB.

Tree-Ring Chronologies of Downy Oak (Quercus Pubescens), Pedunculate Oak (Q. Robur) and Sessile Oak (Q. Petraea) in the Bielinek Nature Reserve: Comparison of the Climatic Determinants of Tree-Ring WidthIn 2004-2006, 50 trees of downy oak (Quercus pubescens), pedunculate oak (Q. robur) and sessile oak (Q. petraea) were sampled in the Bielinek Nature Reserve. The following chronologies were established from their tree-ring series: OMS of 212 years (1793-2004) for downy oaks well as D10 of 183 years (1817-1999) and D13 of 211 years (1789-1999) for the two indigenous oak species pedunculate and sessile oak, respectively. These chronologies were used for signature years and response function analyses. All three chronologies were highly similar, which points to identical responses to the ambient meteorological conditions. The radial increment of downy oak depends primarily on the amount of precipitation. A high annual sum of precipitation, copious rain in spring-summer in particular, results in wide tree rings. Precipitation in form of rain and snow in winter, too, enhance tree growth by raising the groundwater level and improving the water supply in the habitat during the subsequent spring. Droughts in spring and summer, coupled with high air temperature, result in narrow rings. The tree-ring width/climate relationships at the two indigenous oak species are very similar to those of downy oak. Responses are, however, more distinct and with a higher statistical significance.
