Landslide-induced changes in tree-ring anatomy: A new dendrogeomorphic avenue?

CATENA, 2022
The dendrogeomorphic dating of past landslides can be limited by the speed or magnitude of movements, as they are sometimes too small to induce growth responses in trees standing on unstable slopes. As a result, movements of low magnitude are generally assumed to remain undetectable in standard macroscopic analysis of growth disturbances in tree-ring ...

The Tunguska Event in 1908: Evidence from Tree-Ring Anatomy

Astrobiology, 2004
We analyzed tree rings in wood samples collected from some of the few surviving trees found close to the epicenter (within 4-5 km) of the Tunguska event that occurred on the last day of June 1908. Tree-ring growth shows a depression starting in the year after the event and continuing during a 4-5-year period.

Comparative tree-ring anatomy of Fraxinus excelsior with Chalara dieback

Journal of Forestry Research, 2018
We tested the hypothesis that the biometrical characters of wood elements in ash trees (Fraxinus excelsior L.) become modified in response to the progression of disease caused by Chalara fraxinea. Anatomical analyses were performed on wood samples collected at breast height from the trunks of groups of ash trees which contained healthy, weakened and ...

A new sledge microtome to combine wood anatomy and tree-ring ecology

IAWA Journal, 2015
Based on the Reichert Om E microtome a more sophisticated, nevertheless solely mechanically operated microtome was developed enabling to section specimens of various forms and sizes. The materials used and the special construction of the microtome resulted in a higher stability of the moving parts whilst simultaneously reducing weight.

Wood Anatomy and Tree-Ring Structure and Their Importance for Tropical Dendrochronology

2010
In Amazonian floodplain forests, the flood pulse results in an ­alternating aquatic and terrestrial phase per year. Consequentially, trees react with cambial ­dormancy, resulting in differing wood anatomical structures that appear as rings in the cross-section of the trees stem.

Anatomy of the vessel network within and between tree rings of Fraxinus lanuginosa (Oleaceae)

American Journal of Botany, 2004
The three‐dimensional (3‐D) arrangement of vessels and the vessel‐to‐vessel connections in the secondary xylem of the stem of the ring‐porous hardwood tree Fraxinus lanuginosa were studied in series of thick transverse sections with epifluorescence microscope and confocal laser scanning microscope. Vessels were traced in sequential sections, and vessel

The “blue ring”: anatomy and formation hypothesis of a new tree-ring anomaly in conifers

Trees, 2014
Key message Double-stained microsections from high altitude Pinus nigra wood cores highlighted unlignified latewood cells possibly linked to abrupt temperature reduction at the end of the growing season. More consolidated detection could increase their role in dendroecology. Abstract Cambial activity and wood formation are influ- enced by environmental

Learning from the past to improve in the future: tree-ring wood anatomy as retrospective tool to help orchard irrigation management

Acta Horticulturae, 2022
Tree-ring annual growth and wood anatomical traits were used for the retrospective analysis of the impact of hydro-climatic conditions on the orchard irrigation management. Data were collected in the oldest (20 years), in full-production, orchards of Emilia-Romagna (Italy), one of the most important Italian Region for fruit production.
