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.

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 ...

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

Trees and valuation rings [PDF]
Transactions of the American Mathematical Society, 2000 Let \(D\) be a division algebra, finite dimensional over its centre \(F\). The set \(B\) of valuation rings (not necessarily invariant) in \(D\), regarded as a graph, forms a rooted tree (with the maximal element \(D\) as root). The authors ask whether every finite rooted tree can be realized in this way.

The Isomorphism Relation Between Tree-Automatic Structures [PDF]
, 2010 An $\omega$-tree-automatic structure is a relational structure whose domain and relations are accepted by Muller or Rabin tree automata. We investigate in this paper the isomorphism problem for $\omega$-tree-automatic structures.

The role of the 13C isotope of the Tree Ring in Recording of Carbon Cycle Change in Atmosphere
Jurnal Ilmu Dasar, 2014 Some natural materials such as tree rings, rocks, sediments, ice cores, coral reefs, shell fish and micro fossil record the chemical, physical and biological changes in atmosphere that had taken place in the past.

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 ...

Acta Botânica Brasílica, 2016 The tree Piptadenia gonoachantha is widely used in forestry and in forest restoration projects, which require methods for evaluating tree growth. Long-term studies are necessary to determine patterns and detect changes in species growth rhythms.

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 ...
