To assess the drought tolerance of this understudied species, we sampled three Algerian populations along a N-S gradient of increasing aridity: Theniet el Had (sub-humid site, H), Djelba (semi-arid or dry site, D) and Béchar (arid site, A). First, ring-width chronologies were built. Second, correlations between ring-width indices, climate variables, a drought index and teleconnection indices (NAO, North Atlantic Oscillation; MOI, Mediterranean Oscillation index; SOI, Southern Oscillation Index; SaOI, Sahara Oscillation Index) were calculated. A high precipitation in the previous autumn and winter enhanced radial growth of Atlas pistachio and also high June precipitation in the wettest site H. In the driest site A, high maximum temperatures in spring constrained growth. High minimum temperatures in late summer and early autumn enhanced growth in sites D and A, which showed similar year-to-year growth variability (<em>r</em> = 0.426, <em>p</em> = 0.015, period 1980–2011). Correlations with a drought index peaked in the driest site A from September to December. Positive relationships between growth and drought indices in spring and autumn suggest a bimodal growth pattern. The three sites showed positive correlations between growth indices and the April MOI. However, negative relationships were found for January NAO or MOI and spring indices (June NAO, May SOI) in site H. Here, growth rates were negatively related to the SaOI. The Atlas pistachio shows a remarkable drought tolerance and its climate-growth relationships indicate plastic growth responses to precipitation variability.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"91 ","pages":"Article 126326"},"PeriodicalIF":2.7,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143642860","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 study examines the impacts of warming on the radial growth of <em>Picea abies</em> Karst. and <em>Pinus cembra</em> L. in Western Carpathian subalpine forests. We hypothesize that in subalpine zones, where tree growth is predominantly limited by low temperatures, <em>Picea abies</em> will experience enhanced growth under warmer conditions, whereas <em>Pinus cembra</em> will reduce growth under associated stress. We identified two pointer years with negative growth responses in <em>P. cembra</em> (1980 and 2014) and two years (1974 and 1993) with negative growth responses observed only in <em>P. abies</em>. The years 1965 and 1996 were found to be common years of negative response. Results indicate a non-linear relationship between temperature and radial increment. While <em>P. abies</em> and <em>P. cembra</em> both respond negatively to cold years (RWI &lt; 1) at lower temperature sums, their responses diverge at higher temperature sums. As the cumulative sum of daily average temperatures above 9°C exceeds 1500 degree-days, spruce’s response remains positive (RWI &gt; 1), whereas stone pine´s becomes significantly negative (RWI &lt; 0.9).

In Alpine regions, changes in climate may well lead to switches between tree-growth being temperature-limited and precipitation-limited. Distinguishing between these is important as they may express themselves differently in tree rings. However, such switches cannot be separated from more local environmental influences such as elevation and aspect. In this study, we seek to understand how tree growth evolves as a function of elevation in the context of climate change. For the growth of European larch (<em>Larix decidua</em> Mill) in the Turtmann River Basin, a glacier-fed high-elevation river basin in the Swiss Alps, located in southwestern Switzerland, we find that the average temperature increase leads to a switch from temperature-limitation to precipitation-limitation as a function of elevation. The growth of <em>Larix decidua</em> Mill in this river basin is influenced by previous year’s September-October-November (SON) temperature and current year’s January-February-March (JFM) precipitation in the higher- and lower-elevations across an elevational gradient respectively. Based on the analysis from four sites, assuming a linear response, our study suggests that there is a transition zone (i.e., an elevational breakpoint) between 1800 and 900 m AMSL where the signal changes from precipitation-limited to temperature-limited. We also conclude that this elevation breakpoint appears to be rising with time due to increasingly warmer annual average temperatures in this Alpine setting, where this warming is noted to be more than twice compared to the global average temperature change.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"91 ","pages":"Article 126322"},"PeriodicalIF":2.7,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, we developed a preliminary chronology for <em>Araucaria angustifolia</em> in southern Brazil and a compilation of ¹⁴C applications in Brazilian dendrochronology. We tested the synchronicity of tree growth using classical dendrochronological methods on samples from three trees. Radiocarbon analysis of selected tree rings, specifically those formed during the ¹⁴C bomb peak, confirmed the annual nature of growth rings and validated the accuracy of our classical dating. While initial dating discrepancies were observed, these were resolved by considering the variability in the onset of cambial activity for this species. The mean series intercorrelation increased after analyzing the synchronicity in tree growth variability (number of samples n = 3, period 1930–2018) before (<em>r</em> = 0.366) and after (<em>r</em> = 0.423) the adjustments. Our findings demonstrate the effectiveness of combining classical dendrochronology and ¹⁴C dating to establish robust chronologies, particularly for tropical and subtropical species such as <em>A. angustifolia</em> that present dating challenges. This preliminary chronology provides a robust reference for developing a more comprehensive and well-replicated <em>A. angustifolia</em> chronology for subtropical Brazil. Additionally, the literature review showed that radiocarbon dating studies in Brazil, while still relatively scarce (21 studies) and with an uneven geographic distribution, have significantly advanced over the past 5 years.

For instance, both earlywood BI (especially EW10BI) and Delta BI (DBI) showed significant inversed associations with earlywood porosity and with flood-ring abundance. These BI parameters were also strongly associated with spring discharge. In green ash, tree rings formed in years leading to flood-ring formation were characterized by increased earlywood density (higher blue intensity caused by an alteration in size and arrangement of earlywood vessels) and, to a lesser extent, by reduced latewood density. The BI features derived from the earlywood and the entire tree ring both prove to effectively complement visual identification of flood ring. Blue intensity in ring-porous species may prove useful in dendrohydrological reconstructions and also in wood sciences, i.e., when estimating tree-ring density is desired.

This study investigates the relationship between the annual tree-ring width of <em>Fagus orientalis</em> and climate over more than a century at its elevational growth limit. We constructed two tree-ring width chronologies from cores collected at elevations of 2400–2550 m a.s.l. at two contrasting sites in the Hyrcanian Forest, which differ in soil physical conditions. We correlated the tree-ring data with monthly mean temperature, precipitation sums, and the six-month standardized precipitation-evapotranspiration index.

Precipitation has a more pronounced influence on growth at high elevations compared to lower elevations in the Hyrcanian Forests, suggesting that <em>Fagus orientalis</em> is more dependent on precipitation and soil moisture during summer and autumn drought stress. The distance from the Caspian Sea and the constellation of local climatic factors such as low precipitation and high irradiation are likely to contribute to reduced moisture availability at higher elevations. Divergent results from contrasting sites highlight the important role of soil physical conditions in shaping growth-climate relationships.

A one-hundred-year-old white oak stand in an arboretum, along with two second growth (∼200-year-old) stands from Northeast Ohio have consistently responded positively to summer (June-July) precipitation over the past century, whereas four nearby old growth sites (&gt;300 years old) have lost their moisture sensitivity since about the mid 1970s. This “fading drought signal,” which has been previously reported, appears to be more a result of the legacy of land use at the individual sites rather than tree age. The younger oak stands and their relative sustained drought sensitivity is also related to their history of recently attaining the canopy and similar responses associated with intervals of selective logging. All sites are strongly, negatively correlated with summer (June-July) maximum monthly temperatures and in general the maximum temperatures are negatively correlated with precipitation in those months. Future warming in the Midwest is projected to see increases in spring precipitation and likely decreases in late summer precipitation linked to a northward migration of the North American Westerly Jet. This projected decrease in summer precipitation coupled with an increase in maximum and minimum summer temperatures in the coming decades would increase the moisture stress on these trees. Our examination of these varying climate responses with respect to site characteristics and forest age can help future assessments of tree health and the forest’s ability to sequester carbon, as well as facilitate efforts to reconstruct climate by using a range of tree sites for intervals when sensitivity in old growth sites is lost.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"91 ","pages":"Article 126307"},"PeriodicalIF":2.7,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143535351","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}
