A protocol for high-quality sectioning for tree-ring anatomy [PDF]

open access: yesFrontiers in Plant Science
Quantitative wood anatomy (QWA), which involves measuring wood cell anatomical characteristics commonly on dated tree rings, is becoming increasingly important within plant sciences and ecology.

Radiocarbon and wood anatomy as complementary tools for generating tree-ring records in Bolivia [PDF]

open access: yesFrontiers 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 ...

Makro EWVA - učinkovito orodje za analizo prevodnih elementov ranega lesa venčastoporoznih listavcev [PDF]

open access: yesActa Silvae et Ligni, 2014
In this paper, program ImageJ and its application in tree-ring anatomy is presented. The main advantage of the program is its availability and possibility to add additional tools and macros. Platform of ImageJ programme was used to develop macro EWVA for

Paleoecology and paleoenvironments of Podocarp trees in the Ameghino Petrified forest (Golfo San Jorge Basin, Patagonia, Argentina): Constraints for Early Paleogene paleoclimate [PDF]

open access: yesGeologica Acta, 2011
During the Early Paleocene (Danian), Central Patagonia had a warm-temperate climate and was dominated by evergreen coniferous forests. Abundant permineralized conifer woods along with some dicot and palm leaf compressions were found in the Ameghino ...

Retrospective Analysis of Wood Anatomical Traits Reveals a Recent Extension in Tree Cambial Activity in Two High-Elevation Conifers [PDF]

open access: yesFrontiers in Plant Science, 2017
The study of xylogenesis or wood formation is a powerful, yet labor intensive monitoring approach to investigate intra-annual tree growth responses to environmental factors.

Direct Observation of the Developing Intra-Annual Density Fluctuation (IADF) for Scots Pine in Semiarid Siberian Belt Forest: External Stress Targets Cambium [PDF]

open access: yesPlants
Long-term observations of the seasonal growth of Scots pine (Pinus sylvestris L.) tree rings in the arid conditions of the Khakass-Minusinsk Basin (southern Siberia) revealed that in 2024, trees had formed a tree ring with a typical intra-annual density ...

Tree‐Ring Anatomy Improves the Reliability of Temperature Reconstructions Using Relict Wood [PDF]

open access: yesGeophysical Research Letters
Tree rings are crucial for reconstructing past climates, with maximum latewood density (MXD) as a key metric. However, wood integrity is critical for accurate MXD‐based reconstructions, raising concerns when using potentially degraded relict wood ...

Quantitative wood anatomy of Juniperus excelsa from Lebanon as a potential hydroclimate archive [PDF]

open access: yesFrontiers in Plant Science
The Middle East and North Africa is a hotspot for negative climate change impacts and potentially for conflicts over water resources. To protect future generations from destabilization and marginalization, governments need to consider the impact of ...

Dendrochronology and Isotope Chronology of Juglans neotropica and Its Response to El Niño-Related Rainfall Events in Tropical Highlands of Piura, Northern Peru [PDF]

open access: yesPlants
Tropical trees represent an important potential archive of climate and ecological information, but their dendrochronology based on conventional techniques has been challenging.

Towards ROXAS AI: automatic multi-species ring boundaries segmentation as regression in anatomical images [PDF]

open access: yesFrontiers in Plant Science
IntroductionQuantitative wood anatomy (QWA) along a time series of tree rings (known as tree-ring anatomy or dendroanatomy) has proven to be very valuable for reconstructing climate and for investigating the responses of trees and shrubs to environmental
