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.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"94 ","pages":"Article 126440"},"PeriodicalIF":2.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145416547","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}

To investigate the impacts of vegetation growth carryover (VGC) and lagged climate effects (LCE) on vegetation at two distinct scales, tree-ring width (TRW) and enhanced vegetation index (EVI), we focused on <em>Juniperus seravschanica</em>, a dominant species in Tajikistan. Using both TRW and EVI datasets, we employed a vector autoregression (VAR) model to analyze the intensity and duration of vegetation responses to climate through VGC and LCE at different spatial and temporal scales. Our results revealed that both the VGC and LCE effects were stronger in TRW than in EVI. For both indicators, the peak intensity of LCE responses occurred within a lag of 0–3 years, suggesting that this time window is optimal for studying lagged climate effects on vegetation. Except in ZTW (EVI), the contribution of VGC to vegetation growth is much stronger than that of LCE. Moreover, VGC and LCE were found to be decoupled, indicating that their influences on vegetation growth are independent of each other. Ultimately, <em>Juniperus seravschanica</em> appears to adapt to harsh environmental conditions by modulating its growth through both VGC and LCE mechanisms. Investigating VGC and LCE using multi-scale vegetation indicators provides deeper insights into forest ecosystem functioning and offers a more comprehensive perspective for studying vegetation dynamics over time. These findings enhance our understanding of vegetation–climate interactions and offer valuable guidance for vegetation management in arid regions under the context of global climate change.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"93 ","pages":"Article 126393"},"PeriodicalIF":2.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144694960","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}

In forest sciences, the species has received wide attention due to the complex forest decline phase peaking in the late 1970s and the early 1980s in Central Europe, highlighting the negative effects of air pollution of that time. In the era of accelerating climate change with its adverse effects becoming apparent, the species is gaining renewed interest, especially for its further admixing potential to more resilient forest stands. In our study, we investigate the low-frequency radial growth patterns and changes, as well as the interannual variations and the corresponding climatic signal manifested in the tree-ring width chronologies of seven monospecific stands of silver fir. The study sites represent a broad climatic and elevational gradient along the distribution of the species. We compared the identified changes to recent climatic trends with more frequent dry periods since the 1980s, with specific attention to the timescale of the preceding forest decline phenomena. Following decades of radial growth decrease, culminating in severe decline at some sites, a quick recovery and increasing growth marked a period after the early 1980s, regardless of tree age and most pronounced at lower-elevation sites. The period of growth depression and recovery was accompanied by weakened or altered interannual climatic signals. During the recent decades, mean growth has been decreasing again at lower-elevation sites coinciding with drier conditions and shows signs of similar tendencies at some of the humid sites. A recent strengthening of the hydroclimatic signal, however, was not uniform in its timing among the sites. The interpretation of the results can help to further assess the resilience of silver fir to environmental stress, at the crossroads of past legacies, current and predicted challenges.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"93 ","pages":"Article 126384"},"PeriodicalIF":2.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144653361","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}

Moving beyond traditional growth ring analyses, we expanded the Blue Intensity scope by quantifying the high wood density proportions (HighWD), including two HighWD subcategories: latewood and compression wood, in the stems of <em>Picea abies</em> seedlings from Central European treelines. We used BIcounter, a novel tool based on the CooRecorder BI algorithm, to quantify pixel distributions across blue light intensities and estimate HighWD areas as proportions of the total cross-section. Our approach combined BIcounter with densitometry analysis in CooRecorder (both based on BI measurements), allowing us to study compression wood occurrence as a continuous variable, which enhances statistical models’ robustness.

Stem eccentricity was generally high and did not correlate with compression wood proportions. As compression wood accounted for up to 43 % of the treeline seedlings' stem cross-section, its occurrence could affect growth and survival, highlighting the importance of considering compression wood proportions in future ecological research.
