20.500.12556/DiRROS-23996 Spatiotemporal variability of dendroecological indicators in pedunculate oak (Quercus robur L.) tree-rings across Europe in relation to species distribution models Climate is a primary, but non-stationary, driver of tree growth. Climate change is altering the sensitivity of forest growth to water availability and temperature over time. It is considered that pedunculate oak (Quercus robur L.) will cope with the changing climatic conditions in Europe in the near future. However, while species distribution models project expansion zones, they also identify reductions in occurrence at the dry and warm distribution margins. Whereas species distribution models primarily rely on occurrence data, tree rings—given their long-term perspective and their use in empirical models—can provide a mechanistic view of forest growth dynamics, including temporally changing climate responses. Increased climate sensitivity and growth synchrony are key dendroecological indicators of tree stress. Here, we used an unprecedented network of 150 Q. robur sites (over 3300 trees), covering the full projected range of contracting to persistent areas across Europe, to assess the dendroecological indicators over recent decades in relation to species distribution model predictions. We reveal that oaks in areas projected to experience range contraction exhibited greater sensitivity to current growing season climatic conditions, whereas those in persistence areas responded more strongly to previous season conditions. Growth synchrony among trees was higher in the contraction areas, but showed no significant increasing trend over the last 70 years, as expected from ecotone theory. Temporal shifts in climate sensitivity were stronger for temperature and vapor pressure deficit in the persistence areas, whereas the climatic water balance gained importance in the contraction zones. These findings suggest that Q. robur growth is not yet being severely affected by climate change, and that the species is currently coping well with the climate changes, even in regions with projected range contractions, thereby challenging statistically derived scenarios of range shift based on species distribution models. climate change scenarios climate–growth relationships climatic water balance growth synchrony range contraction vapor pressure deficit scenariji podnebnih sprememb odnosi med podnebjem in rastjo podnebno vodno ravnovesje sinhronost rasti krčenje območja razširjenosti primanjkljaj parnega tlaka true false true Angleški jezik Slovenski jezik Znanstveno delo 2025-11-04 14:04:04 2025-11-04 14:04:05 2025-11-05 03:39:51 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Opis vira z dne 4. 11. 2025; str. 1-17 iss. 11 [article no. e70567] Vol. 31 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*1 1365-2486 10.1111/gcb.70567 255853571 https://onlinelibrary.wiley.com/doi/10.1111/gcb.70567 1 bf831d3c-b97e-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35645 Global_Change_Biology_-_2025_-_Popa_-_Spatiotemporal_Variability_of_Dendroecological_Indicators_in_Pedunculate_Oak__Quercus.pdf Global_Change_Biology_-_2025_-_Popa_-_Spatiotemporal_Variability_of_Dendroecological_Indicators_in_Pedunculate_Oak__Quercus.pdf 1 93D88C157CA3D90475FF8C07E5F95B70 9dfd7fa0f294eeb9ff84478d85aebb98fdf570ba0a19048285df96c81fb62293 eae48625-b97e-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35646 Gozdarski inštitut Slovenije 0 0 0
