Stable isotopes in tree rings have a great potential in realizing paleoclimatic reconstructions, representing the newest method of high accuracy and annual resolution for paleoclimate study, which is widely used in Europe, but has been less studied and applied in Romania. Starting a widespread and...

The aim of this study was to compare the climatic responses of three tree rings proxies: tree ring width (TRW), maximum latewood density (MXD), and blue intensity (BI). For this study, 20 cores of Pinus sylvestris covering the period 1886-2015 were extracted from living non-damaged trees from the...

From 1997 to the present, a sustained project in the Maramureș region in Romania was completed with the construction of a 781-year oak tree-ring chronology. A total of 395 samples from living trees and 429 from archaeological wood were analysed with dendrochronological methods. The study aimed to...

High-elevation ecosystems are one of the most sensitive to climate change. The analysis of growth and xylem structure of trees from marginal populations, especially the ones growing at the treeline, could provide early-warning signs to better understand species-specific responses to future climate...

The analysis of the correlative link between the growth processes and the climatic factors with daily resolution allows to remove monthly barriers induced by the monthly time limits. Thus, we can identify cumulative periods in which climatic factors have a high influence on radial growth. This...

We present a comparative study on a 700-yr sequence of dendrochronologically ordered tree-rings of Pinus cembra originating from Eastern Carpathians for the period AD 1009-1709. This period covers the solar minima of the Little Ice Age. The aim of this study was to assess the accuracy of our...

Transcarpathian wooden churches started to dilapidate after World War I. To preserve the architectural heritage, five oak churches were transported from the region to the territory of today's Czech Republic. However, an exact date of their construction and origin of wood have not been specified and ...

Although the importance of centuries-long tree ring width oak chronologies in dating wood, Eastern European regions are still lacking a reference chronology. To fill this geographical gap, we combined living and historical chronologies from the Moldova region, including part of Romania and the...

A tree's radial growth sequence can be thought of as an aggregate of different growth components such as age and size limitations, presence or absence of disturbance events, continuous impact of climate variability and variance induced by unknown origin. The potentially very complex growth patterns ...

Three gridded datasets containing interpolated daily and monthly precipitation and temperature values over the past five decades were tested against four tree-ring chronologies of oak (Quercus robur and Q. petraea). The objective of this research was to investigate the climate-growth relationship...
