“…It should be noted that the data on the age of trees from cores may contain distortions due to the fact that the drill did not hit the center of the sample, but such cores were excluded in our work. For further analysis, 24 cores were selected from 24 trees that met the requirements for the reliability of the results of dendrochronological studies [32][33][34]. For dating and measuring the width of growth rings, we used the LINTAB-6 measuring complex with the TSAP-Win Professional software package [35].…”

“…With the help of software TSAP-Win Professional, the coefficients of similarity of the chronologies of the width of annual rings of each sample with the average chronol-ogy for the surveyed forest stand were calculated (GLK-synchronism coefficient, GSLsynchronism level); correlation coefficient (CC) between the tree-ring width chronologies of each sample and the average chronology for the stand under study; and cross-dating index (CDI) [32].…”

The purpose of our study was to assess the individual variability of the response to climatic conditions of the radial increment of Pinus sylvestris L. trees aged 100–140 years. The studied pine stand grows in the conditions of a site with a heterogeneous microrelief in the Voronezh Reserve. The calculated coefficients of synchronicity and correlation of radial increment of a sample of individual Scots pine trees (wood cores). It has been established that in the radial increment of pine trees in the Voronezh Reserve, there is a significant diversity in the reflection of the climatic signal, which, as a rule, manifests itself in certain years that are not extreme in terms of climatic conditions. The reasons for the differentiated reaction of trees to climate are the differentiated conditions of the microrelief, and also, probably, the genetic diversity of forest stands. In natural stands there are individual trees showing very low values of synchronicity coefficients (GLK, %) or correlation coefficients (CC, %) with stand average values. Intrapopulation differences in the response of pine forest stands to fluctuations in climatic factors are one of the forms of protective mechanisms for the survival of a species that have developed as a result of evolutionary development. As our study showed, intrapopulation differences are large in stands of natural origin and not subject to anthropogenic impacts.

“…Radiocarbon ( 14 C) content in tree rings is also an important tool to independently confirm the dating (Hua et al 1999). However, the 14 C content reflects global astrophysical and geophysical phenomena (solar activity, geomagnetic fields, and climatic variations) (Kairiukstis et al 1990) and anthropogenic effects on the 14 C atmospheric reservoir.…”

Exploring the ¹⁴C Bomb Peak with Tree Rings of Tropical Species from the Amazon Forest

In this work we explore the radiocarbon (14C) signal as an independent tool to assess the year of formation of individual tree rings of tropical species in northern Brazil. Three different species were analyzed in this work: Dipteryx magnifica, Enterolobium maximum, and Hymenolobium petraeum. The studied samples are from the stem of only one individual of each species, all cut down in 2008 in Porto Trombetas, Pará, Brazil. Individual tree rings were identified based on wood anatomy and they were counted from bark to pith. Several rings were selected for 14C analysis in order to cover the overall shape of the 14C atmospheric bomb peak (after 1955). The 14C content was measured at Laboratory of Radiocarbon, Universidade Federal Fluminense (LAC-UFF). Results are compared with the Southern Hemisphere 14C atmospheric calibration curves. For E. maximum and H. petraeum the 14C signal exhibits an overall good match with the SH zone 3 and suggests annual seasonality in the growth-ring formation. These species offer suitable characteristics for dendrochronology. The D. magnifica shows mismatches in the 14C measurements that are likely a result of difficulties in identifying ring boundaries with certainty. Additional techniques may be helpful to disentangle the origin of this discrepancy.
