Dendrochemical research has evolved alongside advancements in analytical techniques like ICP-MS and X-ray fluorescence spectroscopy, enabling high-resolution data collection on trace elements in tree rings. This interdisciplinary field integrates dendrochronology, environmental chemistry, and ecotoxicology, offering valuable insights into historical climate conditions, environmental contamination, and forest health. Key bibliometric analyses reveal that terms like "dendrochemistry" and "trace elements" are central to this research, with applications ranging from environmental monitoring to climate reconstructions. Research clusters indicate strong collaboration networks in North America and Europe, while Latin American countries like Brazil, Chile, and Argentina are forming regional clusters, reflecting a growing research presence. Dendrochemical studies primarily contribute to environmental sciences (35.4 %), to agricultural and biological sciences (22.1 %), and to earth sciences (14.8 %), highlighting their versatility in addressing environmental, ecological, and geoclimatic challenges. Advanced techniques like Itrax multiscanner and ICP-MS have become essential tools, enabling detailed analysis of tree-ring chemistry and improving our understanding of ecosystem dynamics. This systematic review demonstrates the critical role of dendrochemistry in advancing scientific knowledge and emphasizes the need for continued innovation and global collaboration to tackle complex environmental and climatic issues.

The Altai Mountains, recognized as a global biodiversity hotspot and a climate-sensitive region, have shown altered growth patterns of Siberian larch (Larix sibirica) in response to global warming. However, research on river valley forests key habitats within this region has long been limited. This study investigates six representative river valleys in the Altai Mountains. By developing tree-ring width chronologies and analyzing dendroclimatic relationships, we reveal spatially variable growth responses of valley-dwelling Siberian larch to climatic factors. Key findings include the following: (1) Significant spatial heterogeneity was observed in the sensitivity of radial growth to air temperature. In valleys with low moisture availability (XDG and SKE), elevated temperatures constrained larch growth. (2) In valleys with sufficient moisture (TLH and KEM), moderate warming during the growing season enhanced radial growth. Low winter temperatures imposed significant growth limitations across all study sites. Heavy precipitation events during the growing season suppressed radial growth in moisture-saturated soils (TLH and XDG), potentially due to root hypoxia and scouring. (3) Overall, climate change has substantially altered the dominant climatic controls and sensitivity trajectories of Siberian larch radial growth in river valleys. These findings provide a theoretical foundation for conserving river valley forest ecosystems and for developing adaptive management strategies in response to ongoing climate change.

Terrestrial near-surface wind speed (SWS) has experienced notable variations over recent decades, but associated driving factors remain controversial, particularly for monsoonal China. This is largely due to the shortness of instrumental SWS data, and long-term proxy-based reconstructions are thus highly required. Under constant stress from strong unidirectional winds, coniferous trees normally show asymmetric growth patterns via a shift of the geometric center. In this study, we found that variations of the tree-ring geometric center (TRGC) of Pinus massoniana were a good indicator of SWS changes from previous August to current May in the Poyang Lake area of southeastern China, where northerly winds are prevailing and strong before the arrival of the summer monsoon due to the effect of the narrow funnel topography. The TRGC records can explain 66.7 % of the instrumental SWS variance and have been used for a SWS reconstruction since 1949. This reconstruction revealed that the recent SWS decline in the 1970s, and then a reversal occurred in 2010. The reconstructed SWS exhibited a significant correlation with the Atlantic Multidecadal Oscillation (AMO) on the interdecadal scale. Furthermore, the AMO phase shifts may be important driving factors for the change of SWS in the Poyang Lake area. Our study demonstrates that the TRGC method can reconstruct wind speed in the topographically stabilized Poyang Lake area, thereby providing valuable insights into long-term SWS changes in monsoonal China.

The Himalaya supports a rich biodiversity and forest ecosystems providing important ecological services for a vast human population. Owing to the fragility of the Himalaya to environmental changes, precise knowledge about long-term forest functioning under warming-induced climate changes is crucial for future sustainability of forest resources. Treeline responses and changes in the forest-stand structure are indicators of ecosystem response to climate change. Using tree-ring data and tree size parameters, we investigated age-girth-height relationships by developing linear and nonlinear regression models, and calculated treeline shifts based on age-altitude relationships of Abies pindrow (Himalayan Fir) over the last four centuries from the Daksum-Sinthan (DK-SN) and Gulmarg (GUL) sites of Kashmir, western Himalaya. The Fir tree reached its upper elevation limit of >3500 masl by the mid-20th century, with average shift rates over 360 years of ∼1.42 and 1.79 m/yr at GUL and DK-SN, respectively. The recorded highest shift-rate of Fir occurred during the 17th century, coinciding with Little Ice Age climatic episode. Subsequent decline in shift-rates to <1 m/yr, relate to low-moisture conditions during the pre-monsoon months (April-June) hampering seedling establishment. Fir trees showed high recruitment rate during the 19th and 20th centuries at the study sites, as indicated by >50 % population of Fir trees younger than 200 years of age. Warming of spring season and availability of required soil-moisture probably helped to tree recruitment during last 200 years. The near stagnant upper limit of the Fir since last few decades at both sites hints towards the role of non-climatic factors including topography, land-surface-processes, and possibly anthropogenic activities. Our study provides crucial insights on the much-neglected long-term forest-stand dynamics and environmental changes in the treeline ecotone, with wide implications for biodiversity conservation and ecosystem restoration under the pressures of climatic and non-climatic factors.

In recent years, archaeological studies of pile dwellings in the southwestern Balkans have yielded a substantial amount of wood suitable for dendroarchaeological research, offering new opportunities for precise dating of prehistoric settlements and a deeper understanding of their development. Several multi-centennial tree-ring chronologies have been established within the European Research Council (ERC) funded ‘Exploring the dynamics and causes of prehistoric land use change in the cradle of European farming’ (EXPLO) project, spanning from the Neolithic period to the Iron Age, c. 6000–600 BCE in absolute dates, using oak (Quercus sp.), juniper (Juniperus sp.), and pine (Pinus sp.) timber collected from various structural settlement remains.
Using wooden samples from the site of Lin 3, Lake Ohrid, Albania, we have developed new tree-ring chronologies covering the first half and the end of the 6th millennium BCE. Notably, a single juniper tree-ring series extends back to the mid-7th millennium BCE. This Lin 3 juniper chronology was cross-dated to a juniper chronology from the site of Ohridati-Penelopa, located on the north-east side of Lake Ohrid. Thus, the LIN3‐06‐Penelopa combined tree-ring chronology represents the earliest-known continuous tree-ring chronology in the Balkans, spanning 6429–5466 cal BCE (±3 years, 95.4 %) and covering 964 years. Together with other juniper, oak, and pine chronologies from nearby Neolithic waterlogged sites, nearly the entire 6th millennium BCE is now covered. The outer rings of the earliest oak piles with waney edge from Lin 3 date back to 5862–5748 cal BCE (95.4 %), revealing the site as the earliest known Neolithic pile-dwelling of Europe.
Radiocarbon (14C) dating of the LIN3‐06‐Penelopa chronology indicates a potential overlap of 20–30 years with the absolutely dated juniper chronology from Dispilio, Greece. However, the short intersection does not yet allow for their dendrochronological cross-dating.
This article presents these newly constructed chronologies and explores the potential for developing an absolutely dated, multi-millennial tree-ring chronology of the Neolithic period in the southwestern Balkans through a combination of dendrochronology and radiocarbon dating.

The impact of climate change on tree radial growth is a central issue in global change ecology, for which dendrochronology provides crucial long-term data. Here, we conducted a bibliometric and visual analysis of dendrochronological research on tree growth responses to climate change based on 2199 articles from the Web of Science database (2000–2024). The objective is to systematically delineate the developmental landscape of this vibrant, methodologically advancing, and emerging field. The analysis reveals a significant increase in annual publications, driven by technological innovations, enhanced data-sharing mechanisms, and extensive international collaborations, with China, the United States, and European nations constituting the core research contributors. The research focus has profoundly evolved from early climate reconstruction to a detailed deconstruction of the multi-scale “climate-driven–physiological response–ecosystem functioning” mechanisms underlying tree responses. While the antagonistic interplay between the CO₂ fertilization effect and extreme climate stress remains a persistent hotspot, recent research frontiers have increasingly centered on tree adaptation mechanisms under extreme climate events, spatial heterogeneity in responses, and forest resistance and resilience. Crucially, technological advancements and the integration of multidimensional indicators are propelling the field from describing correlations towards investigating the fundamental causal mechanisms by which climate change impacts tree growth. This study systematically elucidates the climate response mechanisms and dynamic trends of tree growth under climate change and analyzes the evolutionary pathways of research hotspots. Its findings offer scientific data to support the formulation of differentiated forest management strategies and the optimization of regional climate policies.
气候变化对树木径向生长的影响是全球变化生态学的一个核心问题，树木年代学为其提供了重要的长期数据。本文基于Web of Science数据库2000-2024年2199篇文章，对树木生长对气候变化响应的年代学研究进行了文献计量学和视觉分析。目标是系统地描绘这一充满活力、方法进步和新兴领域的发展前景。分析显示，在技术创新、增强的数据共享机制和广泛的国际合作的推动下，年度出版物显著增加，中国、美国和欧洲国家构成了核心研究贡献者。研究重点已从早期气候重建深刻演变为对树木响应背后的多尺度“气候驱动-生理反应-生态系统功能”机制的详细解构。虽然CO 2施肥效应与极端气候胁迫之间的拮抗相互作用一直是研究热点，但近年来的研究前沿越来越集中在极端气候事件下树木的适应机制、响应的空间异质性以及森林的抵抗和恢复力等方面。至关重要的是，技术进步和多维指标的整合正在推动该领域从描述相关性转向调查气候变化影响树木生长的基本因果机制。本研究系统阐述了气候变化下树木生长的气候响应机制和动态趋势，并分析了研究热点的演化路径。研究结果为制定差别化森林经营战略和优化区域气候政策提供了科学依据。

This study presents initial results of a tree ring-based blue intensity (BI) study from the western (Indian) Himalayan region. We analysed 139 cross-dated tree core samples of Abies pindrow collected from Hirpora Wildlife Sanctuary (HWS) in the Kashmir Valley, western (Indian) Himalaya. This study was carried out to determine whether BI parameters can enhance tree-ring-based climate signals complementing previous dendroclimatic studies based on ring-widths (RW). We developed six chronologies: total ring width (TRW), earlywood width (EWW), latewood width (LWW), as well as latewood blue intensity (LWBI), earlywood blue intensity (EWBI) and delta blue intensity (deltaBI). Each of the six chronologies spans from 1728 to 2014 CE (287 years) and were correlated with monthly temperature (minimum, maximum and average) and precipitation records to assess their climatic response. The results demonstrated that distinct climate signals can be derived from RW and BI parameters. RW parameters capture moisture stress during the early growing season (May–June). In contrast, the BI parameters, particularly LWBI and deltaBI, yield strong positive correlations with average and maximum temperatures during the late summer (August–September). Additionally, LWBI and deltaBI series are positively associated with minimum winter-spring temperatures. We also evaluated the seasonal climatic response of both RW and BI parameters, assessing the temporal stability of these relationships and developed a transfer function based on a linear regression model. The overall climate signal identified for the BI parameters (LWBI and deltaBI) is distinct from RW and focused primarily on late summer (August–September). Thus, these results demonstrate the strong potential of blue intensity measurements in dendroclimatic reconstructions in the western (Indian) Himalaya.

Thus, these results demonstrate the strong potential of blue intensity measurements in dendroclimatic reconstructions in the western (Indian) Himalaya.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"94 ","pages":"Article 126438"},"PeriodicalIF":2.3,"publicationDate":"2025-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145416545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Wood was used as boards for codices throughout the Middle Ages. The boards provided excellent protection for the vulnerable pages of the codices and, together with the fastenings attached to them, prevented the parchment folios from deforming due to changes in relative humidity. Our research aimed to verify the dating of four codices from the collection of the Diocesan Library in Pelplin (Poland) and to assess their integrity. In doing so, we compared the dating results of the wood used for binding with information derived from such fields as materials science, book technology and paleography. We also analysed decoration, texts, and historical written sources. We examined four manuscripts written between the 12th and 14th centuries. Two codices, namely Petrus Lombardus, Commentaria in Epistolas Pauli PL-Pe 4(8) and Processionale cisterciense PL-Pe 156(204), were bound on beech boards. The other two – Homiliarium PL-Pe 1(2) and Biblia sacra PL-Pe 11(25) – were bound using oak boards. The dendrochronological research revealed that the binding of the manuscript Petrus Lombardus, Commentaria in Epistolas Pauli, written in the 13th century, preserved the original cover boards. The binding, however, had been refurbished at least twice. The last repair was most likely done in Pelplin at the end of the 15th century. As for the three other manuscripts (composite codices), we established the circumstances in which the codices were rebound: they were all rebound in Pelplin in the 14th century using new boards. This means that the Cistercian workshop in Pelplin began rebinding codices no later than the 14th century. In addition, our study shows the variety of wood used and indicate the geographical sources of wood supply.
整个中世纪，木材都被用作抄本的板。这些纸板为易损坏的书页提供了极好的保护，并与它们相连的紧固件一起，防止了羊皮纸开本因相对湿度的变化而变形。我们的研究旨在验证佩尔普林（波兰）教区图书馆收藏的四本抄本的日期，并评估其完整性。在此过程中，我们将用于装订的木材的定年结果与材料科学、图书技术和古文字等领域的信息进行了比较。我们还分析了装饰、文字和历史文字来源。我们检查了四份写于12世纪到14世纪之间的手稿。两个抄本，即Petrus Lombardus， Commentaria in Epistolas Pauli PL-Pe 4(8)和Processionale cisterciense PL-Pe 156(204)，被装订在山毛榉板上。另外两个——Homiliarium PL-Pe 1(2)和Biblia sacra PL-Pe 11（25）——用橡木板装订。树形年表研究显示，13世纪写的《彼得鲁斯·伦巴杜，保利书信集注释》手稿的装订保存了原始的封皮。然而，这本书的封面至少被翻新过两次。最后一次修缮很可能是15世纪末在佩尔普林完成的。至于其他三份手稿（复合抄本），我们确定了抄本被反弹的情况：它们都是14世纪在佩尔普林用新木板反弹的。这意味着佩尔普林的西多会作坊开始重新装订抄本的时间不晚于14世纪。此外，我们的研究显示了所用木材的种类，并指出了木材供应的地理来源。

Shrub species are expected to substitute trees under more arid conditions but how they respond to climate variability in terms of growth and wood-anatomical features is still scarcely understood. Intra-annual density fluctuations (IADFs) are wood-anatomical features widely used to assess how woody plant species respond to climate variability in seasonally dry regions. We investigated how climatic conditions and growth form affect the radial growth responses of four juniper species (Juniperus communis, J. oxycedrus, J. phoenicea and J. thurifera) in Mediterranean Spain. Radial growth and the production of latewood IADFs were measured using dendrochronology. Their relationship with climate variables were also quantified in twelve sites across a continental-coastal gradient. Growth and IADF responses to climate were modulated by species, site and tree factors in juniper species. The series of ring-width indices shared more common variability than IADFs series. Age negatively affected IADF formation, while diameter increased it. Coastal junipers, mainly J. phoenicea, produced more IADFs than those dominant in continental areas such as J. communis. High autumn precipitation and low maximum temperatures enhanced IADF formation. In continental semi-arid sites, J. thurifera trees formed more IADFs and were more sensitive to autumn conditions compared to coexisting J. phoenicea shrubs. J. communis was less responsive to climate variability than J. oxycedrus, which was negatively impacted by spring-to-autumn dry conditions. J. phoenicea growth was also constrained by dry conditions, but warm early-autumn temperatures enhanced it. In conclusion, growth and IADFs production represent different measures of resilience capacity of woody species in seasonally dry environments.
灌木物种有望在更干旱的条件下取代乔木，但它们如何在生长和木材解剖特征方面对气候变化作出反应仍然知之甚少。年际密度波动（IADFs）是木材解剖学特征，广泛用于评估木本植物物种对季节性干旱地区气候变化的反应。研究了气候条件和生长形态对西班牙地中海地区四种杜松（Juniperus communis， J. oxycedrus， J. phoenicea和J. thurifera）径向生长响应的影响。采用树木年代学方法测定径向生长和晚木iadf的产量。它们与气候变量的关系也在横跨大陆-海岸梯度的12个地点进行了量化。杉树生长和IADF对气候的响应受树种、立地和乔木因子的调节。环宽指数系列比IADFs系列具有更多的共同变异性。年龄对IADF的形成有负面影响，而直径则增加了IADF的形成。沿海地区的刺柏，以刺柏为主，产生的iadf高于大陆地区的刺柏。高秋季降水和低最高气温促进了IADF的形成。在大陆半干旱立地，相比于共生的凤梨灌木，沙棘乔木形成了更多的iadf，对秋季条件更敏感。柽柳对气候变率的响应较弱，而柽柳受春秋季干旱条件的负面影响。干燥条件也抑制了凤梨的生长，但温暖的初秋温度促进了凤梨的生长。综上所述，生长和iadf产量代表了木本物种在季节性干燥环境中恢复能力的不同指标。

Preserved Māori wooden artefacts (taonga (treasures)) in Aotearoa New Zealand (NZ), including house components, palisade posts, carvings and canoes, provide valuable insights into the past. Understanding of the age of such objects can add value to their interpretation, determine their association with periods of social, environmental or cultural transition, and help inform future conservation and heritage protection. Empirical scientific methods such as radiocarbon dating are used to establish the calendar age of such objects. However, in NZ limitations on the accuracy of dates are imposed by radiocarbon calibration uncertainties during the last ∼750 years, coincident with the entirety of human occupation in NZ. Additionally, while elsewhere dendrochronology is commonly applied to archaeological wood, in NZ this approach is hampered by species and growth ring characteristics. As a result, dendroarchaeology has been limited to dating kauri (Agathis australis (D.Don) Lindl.) wood from 19th and early 20th century contexts. Here we describe a long-term project employing tree-ring based 14C calibration and stable isotope research that seeks to address these challenges and improve opportunities for the calendar-dating of archaeological sites and taonga in NZ.
