Solar superstorm of AD 774 recorded subannually by Arctic tree rings [PDF]
Nature Communications, 2018 Tree rings retain information of sudden variations of ancient radiocarbon (14C) content, however the origin and exact timing of these events often remain uncertain.

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

Tree rings provide early warning signals of jack pine mortality across a moisture gradient in the southern boreal forest [PDF]
Environmental Research Letters, 2015 Recent declines in productivity and tree survival have been widely observed in boreal forests. We used early warning signals (EWS) in tree ring data to anticipate premature mortality in jack pine ( Pinus banksiana )—an extensive and dominant species ...

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.
