Between 1995 and 2021, archaeological excavations at 16 sites in Ljubljansko barje, Slovenia, collected more than 8,800 samples of waterlogged archaeological wood, mostly from piles driven into the ground on which dwellings were built. About 20% of the samples were from oak (Quercus sp.) and ash (...

Dendrochronological research in NW Spain is aimed at developing reference chronologies of oak (Quercus sp.), which are suitable for absolute age determinations of cultural heritage from the Basque Country. So far, the main research interest has been on rural architecture such as farmhouses and...

This study aimed to suggest a method to establish vessel-lumen-area chronologies in domestic Quercus spp. from Mt. Songni and to verify their potential as a climate proxy. In order to establish vessel-lumen-area chronologies, three options were applied to filter vessels. Options 1 and 2 use vessels ...

Machine learning (ML) is a widely unexplored field in dendroclimatology, but it is a powerful tool that might improve the accuracy of climate reconstructions. In this paper, different ML algorithms are compared to climate reconstruction from tree-ring proxies. The algorithms considered are multiple ...

Charcoal piles have become a frequent subject of research in recent years as a better understanding of past human activities in forests is sought. The age of charcoal piles is usually determined by radiocarbon dating; dendrochronology is rarely used because of the small size of preserved charcoal...

Introduction: One of the most important challenges in climatic studies of Iran is the lack of access to long-term climatic data for all regions; among such regions, one can point to Dena region. This region is in the central Zagros, parts of Isfahan province, ChaharMahal and Bakhtiari, Fars...

The European Dendroecological Fieldweek (EDF) provides an intensive learning experience in tree-ring research that challenges any participant to explore new multidisciplinary dendro-sciences approaches within the context of field and laboratory settings. Here we present the 25th EDF, held in...

Trees can record the long-term effects of climate variables. With the help of dendroclimatology knowledge, these variables can be reconstructed, especially for areas with short-term climatic data. For this purpose, in this study, six forestry plans were selected by using the thickness of Iranian...

In this study, we made use of a regional oak tree-ring network from six stands that cover the northern Moldavian Plateau (Eastern Europe) to analyze how different tree ring parameters (i.e., early wood tree-ring width, late wood tree-ring width, and total tree-ring width) of Quercus sp. are...

The Royal flagship Gribshunden carried the Danish King Hans on its way to the city of Kalmar in Sweden when the ship sank in the summer of 1495. The ship caught fire while anchored north of the Stora Ekö Island and sank to the seafloor, where it lies to this day. The wreck was rediscovered in the...
