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":"2025-07-16","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}

However, extracting this information requires precise visualization of tree-ring boundaries. While species with distinct tree-ring boundaries (e.g., conifers and ring-porous hardwoods) have been extensively studied, diffuse-porous and semi-ring-porous species remain understudied, despite their ecological importance. Addressing this knowledge gap requires improved tree-ring visualization techniques for these challenging species to enable their reliable measurement and crossdating. In this study, we evaluated the effectiveness of various sample preparation and imaging techniques for enhancing tree-ring visibility in 62 temperate tree species <em>sensu lato</em> from East Asia and North America. We compared three preparation methods: increment cores surfaced with a core microtome with and without chalk, and double-stained thin sections. These were combined with four imaging techniques: visible light microscopy and fluorescence microscopy using ultraviolet (UV), green fluorescent protein A (GFPA), and red fluorescent protein 1 (RFP1) filters. The results demonstrated that double-stained thin sections under visible light yielded the clearest tree-ring boundaries, followed by chalked surfaced cores under visible light. Among the fluorescence techniques, UV fluorescence imaging outperformed GFPA and RFP1 fluorescence. Although double-stained thin-section preparation requires greater expertise, it is a reliable, relatively fast, and cost-effective approach that can expand the scope of dendrochronological studies and support broader applications in forest management, climate research, and biodiversity conservation.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"93 ","pages":"Article 126392"},"PeriodicalIF":2.7,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144695067","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":"2025-07-07","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}
