Climate conditions affect wood formation during tree growth with consequences for the functioning and survival of trees and forests. Since tree rings are formed at different temporal windows during the growing season, environmental factors will affect the wood structure and function differently.

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.

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.

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.

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'

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.

<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 & ...

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

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
