Superellipse Equation Describing the Geometries of Abies alba Tree Rings [PDF]
PlantsOur previous study using 41 tree rings of one Abies alba Mill. disc indicated that the superellipse equation can accurately fit its tree-ring shape. This study further used the superellipse equation (xan+yβn=1 ) to model the geometries of 1090 tree rings

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

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