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 ...

Survival, growth and carbon content in a forest plantation established after a clear-cutting in Durango, Mexico [PDF]
PeerJ, 2020 Background Forest plantations play an important role in carbon sequestration, helping to mitigate climate change. In this study, survival, biomass, growth rings and annual carbon content storage were evaluated in a mixed Pinus durangensis and P.

Branch rings, thinned rings, tree enveloping rings [PDF]
Israel Journal of Mathematics, 2006 We develop the theory of ``branch algebras'', which are infinite-dimensional associative algebras that are isomorphic, up to taking subrings of finite codimension, to a matrix ring over themselves. The main examples come from groups acting on trees. In particular, for every field k we construct a k-algebra K which (1) is finitely generated and infinite-

IntCal20 Tree Rings: An Archaeological Swot Analysis [PDF]
Radiocarbon, 2020 ABSTRACTWe undertook a strengths, weaknesses, opportunities, and threats (SWOT) analysis of Northern Hemisphere tree-ring datasets included in IntCal20 in order to evaluate their strategic fit with the demands of archaeological users. Case studies on wiggle-matching single tree rings from timbers in historic buildings and Bayesian modeling of series of

Acta Societatis Botanicorum Poloniae, 2015 The corewood of pine ds very prone to compression wood formation, this changing the whole pattern of the tree ring structure and the siz.es of early and late wood. Compression wood always increases the formation of late wood at the expense of early wood.
