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 (...

Painted chests are an important part of museum collections of folk art in the Alpine region. At the Gorenjska Museum in Kranj, we examined over 30 chests mostly made of Norway spruce (Picea abies) and selected 18 of them for dendrochronological analysis. We took high resolution images of the radial ...

Based on previous measurements from 1962 to 2017 on forest research plots located on former slash-and-burn farming areas in the cadastral municipality of Koprivna, the diameter and height increment as well as volume increments of the two main tree species - spruce and larch - were calculated. These ...

We compared the results of dendrochronological research of mature spruce trees from the stand canopy with the assessment of radial increment on the study plots in spruce stands on Pokljuka. In the comparison, we use raw measurement data (age trend was not removed) from dendrochronological analysis...

We examined the physical properties of oak wood (Quercus sp.) felled four to 512 years ago, grouped in age groups of 100-600 years. The wood originated from recently felled trees and from historical constructions in Slovenia. The selected wood was dendrochronologically dated. We made standardized...

Global warming affects forest ecosystems, which can be observed in increased mortality of trees and drying of increasingly larger forest areas. The cause of global warming is an increase of greenhouse gas concentration in the atmosphere, which is a consequence of excessive fossil fuels,...

During archaeological excavations on wet sites in the area of the ancient Roman Nauportus (today's Vrhnika, Slovenia) in 2005, preserved parts of various wooden structures were discovered. We collected and investigated almost 500 samples of wood from these. Half of the samples were silver fir...

In this article the basic of isotope theory of plant tissue is described. The emphasis is on the main factors and processes, which influence the stable carbon isotopic ratios in tree-rings and on the corrections, which have to be applied before further analysis of stable carbon isotope chronology....

The aim of our study is to fully investigate the relationship between mean monthly temperatures and vessel features. Two vital and one declining groups of pedunculate oak from two Querco-Carpinetum sites in Slovenia are analyzed. Chronologies of mean vessel area and sum of vessel area were...
