Reconstruction of Holocene climate in southern France and eastern Spain using quantitative anatomy of olive wood and archaeological charcoal

Palaeogeography, Palaeoclimatology, Palaeoecology, 1999
Quantitative anatomical analysis of wild olive wood demonstrates that certain criteria are determined by climatic factors. Regression models, developed from modern calibration samples located in French and Spanish Mediterranean regions and charred under controlled thermal and atmospheric conditions, allow us to quantify the response of `vessel density'

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.

Disentangling intra-annual Pinus sylvestris growth responses to hydro-climatic conditions: Insights from quantitative wood anatomy in peatlands

Science of the Total Environment
Peatlands are vital ecosystems that regulate global carbon storage and hydrology, driven by waterlogged conditions that foster organic matter accumulation. However, disentangling the interactions between climate, hydrology, and tree growth in peatlands remains challenging.

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.

Macchia or forest? Toward the reconstruction of Ericaceae formations in Corsica (NW Mediterranean) during the Holocene using a quantitative wood anatomy analysis

Journal of Archaeological Science: Reports
Arbutus unedo L. is very abundant in pre-and protohistoric anthracological assemblages of Corsica (northwestern Mediterranean). In the present day, it is a dominant species, along with Erica arborea L., of the macchia, a shrubland ecosystem that covers a major part of the island.

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.

Simulation study to determine necessary sample sizes for image analysis-based quantitative wood anatomy of vessels of beech (Fagus sylvatica)

Dendrochronologia, 2017
Abstract Quantitative analysis of wood anatomy is a powerful dendroecological tool to provide new insights into environmental signals encoded in tree-rings. Nevertheless, studies with long time series or large sample sizes are not very common for diffuse-porous tree species due to the laborious sample preparation and image analysis.

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.
