Quantitative anatomy or macroscopic parameters of compression wood of Picea abies (L.) H. Karst.? Defining the optimal parameters for dendrogeomorphic purposes

IAWA Journal, 2022
Summary The quantification of the intensities of tree growth responses to the impact of geomorphic processes is a modern research trend in dendrogeomorphology. It enables a more sensitive assessment of the activity of the studied geomorphic process compared to the traditional use of growth disturbances.

Wood anatomy of West European Betula: Quantitative descriptions and applications for routine identification in paleoecological studies

Écoscience, 2003
AbstractIn paleoecological and archaeological studies the species present in wood and charcoal samples are often identified to obtain information about past climatic conditions and vegetation. The main references for identification of Betula at the species level are qualitative descriptions of wood anatomy.

No leaf is an island: The potential of integrating quantitative wood and leaf anatomy

IAWA Journal
Summary A comprehensive understanding of how anatomical traits are coordinated across plant organs is essential for refining trait-based models of plant hydraulic function and for evaluating a species’ hydraulic capacity for acclimation under climate change scenarios.

Fraxinus pennsylvanica trees growing along the central Assiniboine river floodplain, Central Canada: Flood rings, quantitative wood anatomy and blue intensity.

2023
In recent decades, visual identification of flood rings (event years) has been successfully used to document historic high-magnitude spring floods. In Fraxinus spp., flood rings usually have more numerous earlywood vessels and/or earlywood vessels with smaller cross-sectional area than observed in "normal" years.

Quantitative analyses establish the central vascular cylinder as the standard for wood-anatomy studies in lianas having compound stems (Paullinieae: Sapindaceae)

Flora - Morphology, Distribution, Functional Ecology of Plants, 2011
The lianas of the Paullinieae tribe (Sapindaceae) have highly specialized stems which present four different structural variations of the vascular cylinder: divided, compound, corded and fissured. Because each vascular cylinder grows in an independent manner through its own circular cambium, we ask which type should be used for anatomic descriptions of

Miter box holder for quantitative wood anatomy sample preparation

Wood anatomical analysis is a fundamental tool in dendrochronology, ecology, and plant physiology. An important preparatory step is the splitting of wood cores into smaller segments that fit glass slides and standard histology cassettes for microtomy and imaging.

Growth, isotope records and quantitative wood anatomy reveal species-specific couplings in three Mexican conifers inhabiting drought-prone areas

2020
<p>An improvement of our understanding of how tree species will respond to warmer conditions and longer droughts requires comparing their responses across different environmental settings and considering a multi-proxy approach. We used different xylem traits (tree-ring width, formation of intra-annual density fluctuations & ...

Indication of radioactive contamination of forest ecosystems in the zone of the east Ural radioactive trace using methods of quantitative wood anatomy

Èkologiâ
The anatomical structure of the annual rings of Scots pine, formed before and after the Kyshtym accident, is analyzed. In trees growing closer to the central axis of the East Ural radioactive trace (EURT), a decrease in the number of cells in the annual ring, as well as a decrease in the diameter of the lumens and the thickness of the cell walls, was ...
