Выявление и анализ климатического сигнала, содержащегося в годичных слоях дуба черешчатого на юго-восточной границе своего ареала на территории России (бассейн реки Урал).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Материалам для исследования были годичные слои в образцах древесины дуба черешчатого, взятых на трех участках в южной части хребта Дзяу-тюбе. Измерения ширины годичных слоев были выполнены на бинокулярном микроскопе МБС и на измерительном комплексе Lintab с программным пакетом TSAP-WinTM. Построение хронологий радиального прироста осуществлялось в программе ARSTAN. Дендроклиматический анализ проводился в пакете TreeClim в среде программирования R.</p></sec><sec><title>Результаты</title><p>Результаты. Лимитирующим климатическим фактором для радиального прироста дуба черешчатого на юго-восточной границе своего ареала является количество атмосферных осадков за зимневесенний сезон и начальный период вегетации и в наибольшей степени с суммой осадков марта-мая. Показано, что сила этого климатического сигнала в годичных слоях дуба не была постоянной во времени. В динамике этого сигнала характерно наличие локальных участков его снижения, начало которых приурочено к годам массовых размножений непарного шелкопряда.</p></sec><sec><title>Заключение</title><p>Заключение. Начиная с начала 80-х гг. XX столетия произошло значительное уменьшение связи прироста с количеством осадков за март-май. Причиной этого изменения, по нашему мнению, могло быть сильное изменение состояния деревьев и древостоев, вызванное воздействием сильной дефолиации дуба непарным шелкопрядом.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. The objective of this study was to identify and analyze the climatic signal contained in the tree-rings of common oak on the southeastern border of its range in Russia (Ural River basin).</p></sec><sec><title>Material and Methods</title><p>Material and Methods. The materials for the study were tree-rings in samples of common oak wood from three sites in the southern part of the Dziau-tyube ridge. Measurements of ring-width were performed on the MBS binocular microscope and on the Lintab measuring complex with the TSAP-WinTM software package. The construction of tree-ring chronologies was carried out in the ARSTAN program. Dendroclimatic analysis was carried out in the R package treeclim.</p></sec><sec><title>Results</title><p>Results. The limiting climatic factors for the radial growth of the common oak on the southeastern border of its range are precipitation during the winter-spring season and the initial period of vegetation and to the greatest extent with the precipitation in March-May. It was shown that the strength of this climatic signal in oak tree rings was not constant over time. The dynamics of this signal are characterized by the presence of local periods of decline, the beginning of which is timed to the years of mass gypsy moth outbreaks.</p></sec><sec><title>Conclusions</title><p>Conclusions. Since the beginning of the 1980s, there has been a significant decrease in the relationship of radial growth with the amount of precipitation for March-May. The reason for this change, in our opinion, could be a strong change in the condition of trees and stands caused by the consistent impact of strong oak defoliation caused by Gypsy moths and late spring frosts.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Бассейн реки Урал</kwd><kwd>хребет Дзяу-тюбе</kwd><kwd>дуб черешчатый</kwd><kwd>Quercus robur</kwd><kwd>радиальный прирост</kwd><kwd>климатический сигнал</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Ural River basin</kwd><kwd>Dziautyube Ridge</kwd><kwd>common oak</kwd><kwd>Quercus robur</kwd><kwd>tree-rings</kwd><kwd>climatic signal</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Инструментальная часть работы и построение хронологий прироста дуба выполнена в рамках НИР ОФИЦ УрО РАН (ИС УрО РАН) № АААА-А21-121011190016.
