They use a spectrum of growth disturbances in tree-ring series to detect landslide events, one of the most common being abrupt growth suppression. Unlike other growth disturbances, however, this has not yet been studied in detail with regard to its frequency, intensity, or duration in different geomechanical zones of complex landslides. A deeper understanding of this issue would improve the efficiency of dendrogeomorphic sampling, as well as the overall spatial-temporal reconstruction of landslide movements. To obtain a more detailed insight, tree-ring series from 1322 disturbed individuals of <em>Picea abies</em> (L.) Karst. growing on 26 complex landslides with different geological structures were analyzed. The area of each landslide was divided into two contrasting zones with presumed different effects on tree growth (rotational slide zone and earthflow zone). The results showed that the highest incidence of abrupt growth suppression (both in absolute terms and per tree) was in the earthflow zone of landslides developed on rigid sandstone/conglomerate. Conversely, the highest intensity of abrupt growth suppression was found in the rotational slide zone on sandstone/conglomerate. Factors leading to this type of growth disturbance could possibly include root stretching in tension cracks or root shearing at the boundary of rock blocks in the rotational slide zone. In the case of the earthflow zone, root deformation and pinching during flow-like movement of weathered material may play a role. This effect is increased if pieces of rigid sandstone/conglomerate are present in the landslide material.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"95 ","pages":"Article 126479"},"PeriodicalIF":2.3,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146077385","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}

A total of 342 trees (626 tree cores) were collected. Tree-ring width data were analyzed to assess growth sensitivity to climate and air pollution (including CO₂, PM₁₀, NO_x, and SO₂) in the two regions, with a particular focus on growth resilience to extreme drought. The results showed that urban locust growth was primarily driven by climatic factors (with the contribution rate exceeding 93 %), whereas air pollution predominantly influenced rural locust and both urban and rural pine, contributing 62–91 %. Precipitation promoted urban locust growth, while temperature negatively affected both species in two sites. CO₂ enhanced locust growth but suppressed pine. NO_x showed opposing effects: negative for urban locust and positive for pine, while PM₁₀ benefited rural locust and pine. SO₂ consistently inhibited pine growth. The findings indicate that combined climate and air pollution factors heightened the sensitivity of urban trees to urbanization and climate change. Both species showed notable growth decline under extreme drought (resistance &lt; 1) and good recovery (resilience &gt; 1, recovery time &lt; 3 years), with a significantly higher recovery of pine compare with locust, particularly for urban areas. This suggests urban irrigation can alleviate the water stress for both species. Despite drought, both urban and rural trees demonstrated good recovery capacity, suggesting that moderate drought is unlikely to cause immediate decline. Growth resilience to extreme drought in both species was primarily influenced by tree age, basal area, and pre-drought growth.

In this study, we reconstructed the Normalized Difference Vegetation Index (NDVI) for <em>Austrocedrus chilensis</em> forests in northwestern Argentine Patagonia using multi-centennial tree-ring chronologies. A total of 162 wood samples from living trees and 65 from dead trees were used to develop the regional chronology, which exhibited a significant and positive correlation with NDVI from January to March over the period 1981–2019. Based on this relationship, a linear regression model was applied to reconstruct NDVI for these months extending back to 1405. The reconstruction explained 44 % of the total NDVI variance and showed significant positive associations with the Standardized Precipitation Evaporation Index (SPEI), the Palmer Drought Severity Index (PDSI), and the Southern Annular Mode (SAM). Long-term cycles in vegetation productivity were detected, potentially linked to solar activity and other low-frequency climate forcings. The results indicate secular changes in forest productivity dynamics, reflecting the influence of ongoing climate change. By providing a multi-century perspective on NDVI variability, this reconstruction offers critical insights into past forest dynamics and establishes a robust baseline for understanding contemporary ecosystem functioning.

Through dendrochronological dating, laser scanning and comparisons with modern reconstructions, we argue that at least 13 timbers derive from an earlier use, seven of which are interpreted further in this paper. The dendrochronological analysis revealed a narrow felling period between 688 and 694 AD with multiple samples showing a preserved waney edge. The identification of recycled timber was largely built on the observation of nonsensical timber carvings and surface hewing, which was deemed unnecessary in the construction of a pathway. We argue that the presented timbers originate from a three-aisled longhouse from the late Danish Iron Age. Furthermore, we can confidently place them within the architecture of the longhouse and identify them as wall-posts, roof-carrying posts and, most notably, two crossbeams and a head-beam — the first archaeological observations of such from prehistoric Scandinavia. The Varpelevvej II timber corpus highlights the importance of recognizing reuse and the better preservation potential of architectural features in secondary deposits.

This suggests that living individuals had a higher capacity to plastically adjust to environmental conditions, reflected in a bimodal growth pattern. Overall, our findings highlight IADFs as growth-based early-warning signals of tree mortality, mechanistically linked to the individual ability to withstand unfavorable climatic conditions.

This study compares the climatic sensitivity of <em>Pinus sylvestris</em> L. trees and <em>Juniperus communis</em> L. shrubs in northern Norway, Øvre Pasvik region, positioned at the Europe’s northernmost treeline. Specifically, we aimed to assess whether the temperature sensitivity of two co-existing woody plant forms at the northern treeline are coherent and stable over time.

While increased drought stress is often suggested as a cause for temperature signal loss in high latitudes, this does not appear to be the case in Øvre Pasvik, as correlations between <em>Juniperus</em> shrubs and SPEI are generally weak or negative for the recent period. Additionally, growth of <em>Pinus</em> trees was positively related to May precipitation, while <em>Juniperus</em> shrubs exhibited negative relationship with May precipitation.

For these two Mediterranean pine species with different life-history traits (<em>Pinus pinea</em> and <em>Pinus pinaster</em>), were studied using dendrochronological data, in two areas of Portugal with distinct Mediterranean Type climate (Csb - warm-summer Mediterranean, and Csa - hot-summer Mediterranean).

Our results reveal that increased warming after the 1970s induced contrasting species-specific responses. Fast growing <em>P. pinaster</em> had enhanced growth during favorable conditions at mesic sites. In contrast, the more xeric <em>P. pinea</em> reduced growth under warming, indicating a change in consideration of these two species capacities to cope with future climatic conditions. We have not found an increase in sensitivity to water availability during warming, therefore, future drought recovery for both species will largely depend on local declines in water availability.
