We quantified cork and wood production and cork responses to climate variability and drought indices at dry (slope ridge) and wet (valley bottom) sites located in a relict cork oak population in north-eastern Spain. We also calculated intrinsic water-use efficiency cork (iWUE) by analysing C isotope ratios (δ<sup>13</sup>C) in annual cork samples.

Cork and radial growth covaried in both sites and the slopes of their linear regressions were similar between dry and wet sites. In the dry site, cork width increased as June-July soil moisture did, whereas cork iWUE decreased as May soil moisture increased. Moist soil conditions in the prior October and March also enhanced cork growth at both sites, whilst wet prior winter conditions reduced cork iWUE at the dry site. Our findings show how cork production depends on local soil water availability.

We hypothesized that species of timber used in constructions prior to the late 19th century were commonly available in forests within a short distance from the location of the constructions. To test this hypothesis, we compared high-resolution archival information on the tree species composition of forests in Moravia (eastern Czech Republic, ca. 27,000 km<sup>2</sup>) in the 18th and 19th centuries to a database of 1231 dated timber constructions in the same region and period. Our analysis was based on the mutual distances between the locations of timber constructions and the occurrences of forests with the given tree species. We compared real distances with distances obtained through random simulations. Results showed that in more than half of the cases, the tree species from constructions occurred in the forests of the same township. In the rest of the cases, the modal distance values to the centroid of the nearest township where the same species was present in the forests were usually less than two kilometres and distances larger than five kilometres were generally rare. While our results testify to the availability of timber rather than to the direct source of particular pieces of timber, they strongly suggest that timber was usually sourced locally. We believe our interdisciplinary study demonstrated the usefulness of archival data in the research of timber sourcing. For future studies, we see the combination of our approach with dendroprovenancing and other natural scientific methods as the most promising way to gain deeper knowledge on the sourcing of timber.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"91 ","pages":"Article 126337"},"PeriodicalIF":2.7,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143815127","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}

We analyzed 43 trees distributed across the 18 most common species in two restoration stands. Trees (35) from all the species evidenced crossdatable growth rings, allowing us to construct a robust multi-species ring-width chronology. This unprecedented community-level signal in the tropics was determined by a one-year lagged tree-growth response to water availability and temperature. The dynamics of non-structural carbohydrates (NSC) are likely involved in this delayed climatic effect. Relatively homogeneous light conditions among trees in the stands would be critical for detecting the growth signal. Whether such a community-level signal would be found elsewhere and the role of NSC in mediating tree growth responses to climate deserve further investigation. Tree-ring analysis allowed us to assess the climatic sensitivity of a forest community undergoing restoration and could further address several other relevant issues towards restoring tropical ecosystems.

We analyzed annual tree-ring width (TRW) and applied a triple isotope approach (i.e., carbon (δ<sup>13</sup>C), oxygen (δ<sup>18</sup>O), and hydrogen (δ<sup>2</sup>H) isotopes) in tree-ring cellulose for the period 1960–2020. To retrieve tree physiological responses, we normalized the tree-ring δ values to temporal isotopic variations in CO<sub>2</sub> or precipitation (Δ). Δ<sup>13</sup>C and Δ<sup>18</sup>O values suggest that the early-browning trees had a more conservative water-use strategy and lower stomatal conductance than the vital trees in the initial decades of the measurement period. However, several decades before the onset of crown dieback in 2018, the early-browning trees showed a decrease in TRW and an increase in Δ<sup>2</sup>H, suggesting a higher use of carbon reserves for the early-browning trees. These long-term trends may be the first signs of a progressive deterioration of the physiology of the early-browning trees. During and after the 2018 drought, changes in Δ<sup>2</sup>H suggested high carbon investments into drought damage repair for the early-browning trees. Moreover, a higher TRW and isotope sensitivity to previous year’s summer climate in early-browning than vital trees suggests stronger negative carry-over effects. Our findings highlight that the early-browning trees may have already been weakened before the 2018 drought, eventually pushing them beyond their physiological tipping points and inducing dieback.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"91 ","pages":"Article 126335"},"PeriodicalIF":2.7,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807325","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}

This note aims to clarify key aspects of the t-statistic and its associated Pearson’s correlation coefficient in the context of dendroprovenance.

Here, the focus shifts from the correlation coefficient to the t-statistic, highlighting both its potential and its limitations. Unlike the linear relationship observed between distance and Pearson’s correlation coefficient, the association between distance and the t-statistic is more pronounced at shorter distances, where correlations are higher.

Additionally, the age of the oldest non-native species indicates they were planted during the third stage of development (1815–1865), with further plantings occurring during the fourth stage (1865–1918). Our study supports the idea that this historical park has been continuously modified and developed throughout its history from the late 18th to early 20th century.
