These are the two most commonly used tree species in dendrogeomorphic landslide research in Central Europe and their combination is generally recommended. However, their specific effect on the resulting chronology is not yet taken into account although they are two quite different species. The research was conducted on 220 individuals of both species located in the Girová landslide area (Outer Western Carpathians), with a focus on the catastrophic event of May 2010. The study sought to understand how these species contribute to dendrogeomorphic reconstructions of landslide events, particularly by analyzing their growth responses and the frequency of growth disturbances (GDs) such as compression and tension wood. The results revealed significant differences in how <em>P. abies</em> and <em>F. sylvatica</em> responded to landslide activity. <em>P. abies</em> showed a higher frequency of GDs (compression wood), but exhibited greater inertia in its physiological response, potentially masking high-frequency landslide events. In contrast, <em>F. sylvatica</em> produced fewer GDs (tension wood), yet its response to landslides was more immediate and efficient, with 100 % intensity in tension wood formation, which helped create a minimum-noise chronology despite fewer identified events. The study highlights the advantages and limitations of both species in dendrogeomorphic research. While <em>P. abies</em> contributes more frequently to detecting landslide events, the inertia in compression wood formation can complicate the interpretation of rapid landslide movements. On the other hand, <em>F. sylvatica</em>, though less responsive in terms of GDs, provides a clearer and more precise landslide chronology. Future research should explore the physiological factors behind these species' different responses to enhance the accuracy of dendrogeomorphic reconstructions.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"92 ","pages":"Article 126368"},"PeriodicalIF":2.7,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138633","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}

Additionally, a limitation of using ring widths is that it fails to capture the detailed responses to signals from short-term climatic variability preserved in wood chemistry and cellular anatomy. Recently, stable isotope and quantitative wood anatomy have shed light on these perspectives, enabling the extraction of climatic signals even from specimens that were previously considered unsuitable. This study aims to evaluate the potential of quantitative tracheid anatomy in <em>Cryptomeria japonica</em> trees of approximately 70 years of age from a humid-temperate region, Ashiu Forest Research Station, as a proxy for climate signals and a crossdating index, despite being suboptimal under conventional dendrochronological principles.

According to a correlation analysis, daily precipitation in July (rainy season) of the current year was highly correlated with the lumen radial diameter (<em>r</em> = 0.71). The lumen radial diameter was also useful for reliably crossdating (Student’s <em>t</em>-value = 7.34) <em>C. japonica</em> specimens from 1965–2016 that could not be crossdated by ring widths.

We assessed radial-growth variability and responses to climate variables in three stands dominated by sessile oak (<em>Quercus petraea</em> (Matt.) Liebl.) located in western Romania: a very old unmanaged stand, an old managed stand from seed origin and a young managed stand from sprout origin. There was a shift towards warmer and drier conditions from the 1980s onwards which could have contributed to reduce temporal growth variability, but it did not increase growth coherence among coexisting trees. Very old and old stands showed a higher growth variability among conspecifics comparing with the young stand, which presented a higher growth synchrony. Warm and dry summers and elevated vapor pressure deficit reduced sessile oak growth. The highest responsiveness of growth indices was found for 12-month long droughts ending in summer in the case of young and old managed stands, whereas the very old unmanaged stand showed the lowest responsiveness. Improving tree growth of younger and even old managed stands may make them more responsive to summer soil and atmospheric drought, thus increasing their vulnerability to further water shortage.

However, earlywood vessel chronologies in ring-porous species often show low statistical quality, such as weak common signal strength and low expressed population signal (EPS). This raises questions about whether these limitations are inherent to the wood type or if methodological refinements could improve chronology robustness. This study evaluates how the amount of measured wood per ring (tangential width) and tree replication impacts the statistical quality and reliability of climate-growth relationships. Therefore, we conducted a systematic analysis using a highly replicated dataset (21 trees per site, 45 mm tangential width per tree) from <em>Fraxinus excelsior</em> and <em>Quercus robur</em> as a robust benchmark. We employed advanced image analysis, resampling, and data simulation techniques. Our analyses show that the spread (uncertainty) of obtained climate correlation values increases with lower replication and common signal strength, with replication as the most influential factor, followed by within-tree accuracy linked to the tangential width. We recommend collecting at least two 5-mm cores (8–10 mm TW) per tree and sampling a minimum of 20 trees in environments without a strong limiting factor (low common signal strength). In contrast to common practice, we promote subsampling based on surface quality rather than high correlation with the tree-ring width master chronology and target an EPS ≥ 0.85 for earlywood vessel chronologies. Finally, careful screening within the array of earlywood vessel variables (first row, mean size, different quantiles, etc.) enables to maximize the signal strength.
