CLIMATIC SIGNALS FROM INTRA-ANNUAL DENSITY FLUCTUATION FREQUENCY IN MEDITERRANEAN PINES AT A REGIONAL SCALE [PDF]

open access: yesFrontiers in Plant Science, 2016
Tree rings provide information about the climatic conditions during the growing season by recording them in different anatomical features, such as Intra-Annual Density Fluctuations (IADFs).

Pointer years in the growth of beech trees of the NP "Đerdap" area [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2014
This paper defines pointer years and years with distinctive tree rings in the growth of beech in 3 sites (ecological units-EU) of the area of Đerdap, in order to observe the reactions of trees to the effects of various factors of growth.

Olive tree-ring problematic dating: a comparative analysis on Santorini (Greece). [PDF]

open access: yesPLoS ONE, 2013
Olive trees are a classic component of Mediterranean environments and some of them are known historically to be very old. In order to evaluate the possibility to use olive tree-rings for dendrochronology, we examined by various methods the reliability of

A new approach to developing a logistic regression model variables to predict tree mortality, based on tree-ring growth dynamics [PDF]

open access: yesСибирский лесной журнал, 2020
The annual tree increment is one of the integral indicators of abiotic and biotic processes occurring in the forest ecosystem. The use of logistic regression models based on annual tree-ring growth data is a promising approach to studying tree mortality.
