A protocol for high-quality sectioning for tree-ring anatomy

Frontiers 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.

Tree ring segmentation using UNEt TRansformer neural network on stained microsections for quantitative wood anatomy

Frontiers in Plant Science
Forests are critical in the terrestrial carbon cycle, and the knowledge of their response to ongoing climate change will be crucial for determining future carbon fluxes and climate trajectories.

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

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 ...

Climatic Influences on Wood Anatomy and Tree-Ring Features of Great Basin Conifers at a New Mountain Observatory [PDF]

Applications in Plant Sciences, 2014
Premise of the study: A network of mountain observing stations has been installed in the Great Basin of North America. NevCAN (Nevada Climate-ecohydrological Assessment Network), which spans a latitudinal range of 2.5° and two elevation ranges of ...

Changes in Wood Anatomy in Tree Rings of Pinus pinaster Ait. Following Wounding by Flash Floods [PDF]

Tree-Ring Research, 2010
This paper analyzes the anatomical response of Pinus pinaster Ait. following wounding by flash floods. A total of 14 wood samples were taken from 14 different scarred trees located on the river banks of the Arroyo Cabrera torrent (Spanish Central System). In addition, 20 increment cores were collected from undisturbed and healthy P.

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

Geophysical 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 ...

Contribution of Xylem Anatomy to Tree-Ring Width of Two Larch Species in Permafrost and Non-Permafrost Zones of Siberia [PDF]

Forests, 2020
Plants exhibit morphological and anatomical adaptations to cope the environmental constraints of their habitat. How can mechanisms for adapting to contrasting environmental conditions change the patterns of tree rings formation? In this study, we explored differences in climatic conditions of permafrost and non-permafrost zones and assessed their ...

Siberian spruce tree ring anatomy: imprint of development processes and their high-temporal environmental regulation [PDF]

Dendrochronologia, 2019
Abstract Wood anatomy was offered as spatiotemporal proxy record for tracheid differentiation kinetics due to its advantages in terms of much longer cover period and less demanding measurements. In this study, external and internal regulation of earlywood-to-latewood transition and properties of latewood of Picea obovata Ledeb were considered.

Exclusive application of tree-ring anatomy for reconstruction of past landslide behavior

Landslides
Abstract Tree-ring-based analyses currently represent a modern, continuously evolving, and effective tool for the spatio-temporal reconstruction of past landslide movements. Although the use of standard macroscopic landslide signals is still more common, this classical approach has significant limitations. Recent research, however, shows that

Growth Rate, Tree Rings, and Wood Anatomy of a Tropical Cloud Forest Tree Invader

Forests
The presence of shade-tolerant tree invaders has been recently noted in tropical and temperate forest understories. Maximum growth rate is an important trait for exotic trees becoming invaders in a forest. This study aimed to determine the growth rate of Eriobotrya japonica in a secondary cloud forest in central Veracruz, Mexico. The objectives of this
