14C in tree rings in the vicinity of the nuclear facility deployment areas [PDF]
Nuclear Energy and Technology, 2022 14C is naturally and artificially occurred radionuclide presented in atmosphere. 14C is produced during the operation of a nuclear reactor of any type, enters the atmosphere and became a part of carbon cycle. The article presents the results of measuring

Environmental Research Letters, 2023 Tree rings can reveal long-term environmental dynamics and drivers of tree growth. However, individual ecological drivers of tree growth need to be disentangled from the effects of other co-occurring environmental and climatic conditions in tree rings to

Radiocarbon and wood anatomy as complementary tools for generating tree-ring records in Bolivia
Frontiers in Plant Science, 2023 The science of tropical dendrochronology is now emerging in regions where tree-ring dating had previously not been considered possible. Here, we combine wood anatomical microsectioning techniques and radiocarbon analysis to produce the first tree-ring ...

Monthly river flow modeling using earlywood vessel feature changes, and tree-rings
Ecological Indicators, 2021 Temporal records of river flow as essential data for water resource management plans are not available in many rivers around the world. In this study, monthly discharges of the Taskoh river in the north of Iran were simulated using dendrohydrology (the ...

Capturing spiral radial growth of conifers using the superellipse to model tree-ring geometric shape
Frontiers in Plant Science, 2015 Tree-rings are often assumed to approximate a circular shape when estimating forest productivity and carbon dynamics. However, tree rings are rarely, if ever, circular, thereby possibly resulting in under- or over-estimation in forest productivity and ...

Frontiers in Forests and Global Change, 2023 AimsThrough analyzing the responses of the radial growth and element concentrations (B, Mg, Al, K, Ca, Mn, Fe, Zn, Na, P, Ni, and Cu) of tree rings of two dominant tree species to forest fires, we aimed to investigate the relationship between tree rings ...
