20.500.12556/DiRROS-15355 Turkey oak (Quercus cerris L.) is more drought tolerant and better reflects climate variations compared to pedunculate oak (Quercus robur L.) in lowland mixed forests in northwestern Serbia : ǂa ǂstable carbon isotope ratio (δ13C) and radial growth approach Tree-ring width (TRW), stable carbon isotope ratio (δ13C) and intrinsic water use efficiency (iWUE) data set chronologies were built for the period 1961–2000 for two oak species (pedunculate oak – Quercus robur L. and Turkey oak – Quercus cerris L.) in northwestern Serbia (Vojvodina province). We focused on the response of the two oak species to measured meteorological data (temperature, precipitation and cloud cover), drought events expressed by six meteorological drought indices, and river water level to better understand their drought tolerance and stress and to assess the reliability of the species response to climate and drought indices when using TRW or δ13C. Turkey oak exhibited better drought tolerance (and less drought stress) compared to pedunculate oak, as manifested, respectively, by less negative δ13C and lower iWUE values. Based on a generalised additive mixed model (GAMM) among the six drought indices studied, the standardised precipitation evapotranspiration index and the standardised precipitation index showed the best fit with both TRW and δ13C, while the Palmer drought severity index exerted a strong influence only on TRW. It was thus concluded that δ13C responds more strongly and rapidly to climate variations than TRW. dendrochronology stable carbon isotope tree ring Quercus robur Quercus cerris drought climate change dendrokronologija stabilni ogljikov izotop branike Quercus cerris cer Quercus robur dob suša podnebne spremembe true false true Angleški jezik Ni določen Neznano 2022-08-04 07:44:44 2022-08-04 07:44:44 2022-08-21 03:37:02 0000-00-00 00:00:00 2022 0 0 str. 1-11 article 109242 Vol. 142 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*1:630*5 1470-160X 10.1016/j.ecolind.2022.109242 117186307 RAZ_Kostic_Sasa_i2022.pdf RAZ_Kostic_Sasa_i2022.pdf 1 ABA70C6957E5107E812D610AD8146014 152b32c43c4b7ae737b70e21566bc25d1fc35f16c9fc282eb4468d9110aac9de fc3abba4-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=20282 https://www.sciencedirect.com/science/article/pii/S1470160X22007142?via%3Dihub 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=20280 Gozdarski inštitut Slovenije 0 0 0
