The current use of herbaria reaches far beyond their initially aims; among the new applications, phenology observations and conservation biology can be mentioned. However, to this date, no studies on the use of herbarium specimens for dendrochronological research have been published

Possibilities and limits of dendrogeomorphic data as a basis for defining thresholds for landslide triggering Dendrochronologia (IF 3.0) Pub Date : 2023-05-25 Karel Šilhán, Richard Andrášik, Vojtěch Nezval, Michal Bíl
Dendrogeomorphic (tree-ring based) methods are an effective tool for determining the spatial and temporal activity of landslide movements. Moreover, the obtained chronological data can be used for the analysis of their potential triggers. However, the use of tree-ring based chronologies for defining trigger thresholds is very rare and has not yet been critically evaluated. Given the well-known limitations

Responses of radial growth and stable carbon isotopes to climate in the northern Tianshan Mountains Dendrochronologia (IF 3.0) Pub Date : 2023-05-19 Li Qin, Yujiang Yuan, Shulong Yu, Huaming Shang, Tongwen Zhang, Ruibo Zhang
Climate change has profound effects on forest ecosystems. Schrenk spruce (P. schrenkiana) is a natural conifer species endemic to the arid inland areas of Asia. In this study, the relationship between tree-ring parameters of P. schrenkiana and major meteorological factors were analyzed, and the main limiting factors for tree radial growth and stable carbon isotope fractionation were explored. Our results

Three-dimensional distribution of mass movement signals in disturbed Picea abies (L.) Karst. Dendrochronologia (IF 3.0) Pub Date : 2023-05-18 Andrea Fabiánová, Karel Šilhán
Dendrogeomorphologic approaches enable annual absolute dating of various potentially hazardous geomorphic processes. This study tested the dating precision of three commonly used dendrogeomorphic approaches used for the extraction of geomorphic signals from the tree ring series of disturbed trees. The first approach is based on the onset of reaction wood occurrence, and the other two approaches are

Detrending climate data prior to climate–growth analyses in dendroecology: A common best practice? Dendrochronologia (IF 3.0) Pub Date : 2023-05-05 Clémentine Ols, Stefan Klesse, Martin P. Girardin, Margaret E.K. Evans, R. Justin DeRose, Valerie Trouet
Tree growth varies closely with high–frequency climate variability. Since the 1930s detrending climate data prior to comparing them with tree growth data has been shown to better capture tree growth sensitivity to climate. However, in a context of increasingly pronounced trends in climate, this practice remains surprisingly rare in dendroecology. In a review of Dendrochronologia over the 2018–2021

Dendroarchaeology at Lake Ohrid: 5th and 2nd millennia BCE tree-ring chronologies from the waterlogged site of Ploča Mičov Grad, North Macedonia Dendrochronologia (IF 3.0) Pub Date : 2023-05-09 Bolliger Matthias, Maczkowski Andrej, Francuz John, Reich Johannes, Hostettler Marco, Ballmer Ariane, Naumov Goce, Taneski Bojan, Todoroska Valentina, Szidat Sönke, Hafner Albert
The prehistoric site of Ploča Mičov Grad (Ohrid, North Macedonia) on the eastern shore of Lake Ohrid yielded a total of 799 wooden samples from a systematically excavated area of nearly 100 square meters. Most of them are pile remains made of round wood with diameters up to almost 40 cm. A comprehensive dendrochronological analysis allows the construction of numerous well-replicated chronologies for

A new 500-year reconstruction of Truckee River streamflow Dendrochronologia (IF 3.0) Pub Date : 2023-05-02 Victoria M. Harris, Adam Z. Csank
The Truckee River Basin, located on the Nevada-California border, is an area of extreme hydrologic variability, being subject to both prolonged multi-decadal droughts and devastating floods; however, due to the brief instrumental record, understanding of the full range of this variability is limited. To assist local water managers assess the post-2000 drought in the context of historic droughts, this
