Elemental Variability in Stems of Pinus sylvestris L.: Whether a Single Core Can Represent All the Stem

Diversity, 2023
In dendrochemical studies, an analysis of wooden cores extracted from tree stems is a widely spread research method. A methodological problem is related to the method: whether a single core per tree can be representative of all the stems. The study aimed

Spurious shear induced by the tree rings of the LSST CCDs

, 2015
We present an analysis of the impact of the tree rings seen in the candidate sensors of the Large Synoptic Survey Telescope (LSST) on galaxy-shape measurements. The tree rings are a consequence of transverse electric fields caused by circularly symmetric

Growth trends reveal the forest structure during Roman and Medieval times in Western Europe: a comparison between archaeological and actual oak ring series (Quercus robur and Quercus petraea) [PDF]

, 2005
At some point in time, man has influenced nearly all forests in Western Europe. Most of the original forest cover has been converted to arable land and pastures, or has been cut for the supply of firewood and construction timber.

Variation of major elements and heavy metals occurrence in hybrid aspen (Populus tremuloides Michx. × P. tremula L.) tree rings in marginal land

iForest - Biogeosciences and Forestry, 2020
Fast growing tree species such as Populus spp. in short rotation woody crop (SRWC) systems could be an environmentally friendly and cost-effective approach to ensure sustainable biomass production and mitigate the negative impacts on the environment ...

Does Cedrela always form annual rings? Testing ring periodicity across South America using radiocarbon dating

, 2017
Tropical tree rings have the potential to yield valuable ecological and climate information, on the condition that rings are annual and accurately dated.

Radiocarbon releases from the 2011 Fukushima nuclear accident [PDF]

, 2016
Radiocarbon activities were measured in annual tree rings for the years 2009 to 2015 from Japanese cedar trees (Cryptomeria japonica) collected at six sites ranging from 2.5–38 km northwest and north of the Fukushima Dai-ichi nuclear power plant. The 14C

DendroSync: An R package to unravel synchrony patterns in tree-ring networks [PDF]

, 2017
Spatial synchrony refers to the presence of a common signal for a time-varying characteristic that, in dendrosciences, is shared among tree-ring chronologies from a particular area.

Projected changes in early summer ridging and drought over the Central Plains

Environmental Research Letters, 2022
Early summer (May–June–July; MJJ) droughts over the Central Plains are often caused by atmospheric ridging, but it is uncertain if these events will increase in frequency or if their influence on drought severity will change in a warming world.
