Controlled Breaking of Mummified Wood For Use In Paleoenvironmental Analysis [PDF]

, 2013
The discovery of exceptionally well-preserved Paleogene wood fossils (ca. 55–53 Ma) within Canadian Arctic diamond-bearing kimberlites prompted a paleoclimatic study of the Paleocene-Eocene Transition.

A band model of cambium development: Opportunities and prospects [PDF]

, 2021
More than 60% of tree phytomass is concentrated in stem wood, which is the result of periodic activity of the cambium. Nevertheless, there are few attempts to quantitatively describe cambium dynamics.

High-Resolution X-Ray Computed Tomography: A New Workflow for the Analysis of Xylogenesis and Intra-Seasonal Wood Biomass Production

Frontiers in Plant Science, 2021
Understanding tree growth and carbon sequestration are of crucial interest to forecast the feedback of forests to climate change. To have a global understanding of the wood formation, it is necessary to develop new methodologies for xylogenesis ...

Direct and Indirect Effects of Environmental Limitations on White Spruce Xylem Anatomy at Treeline

Frontiers in Plant Science, 2021
Treeline ecosystems are of great scientific interest to study the effects of limiting environmental conditions on tree growth. However, tree growth is multidimensional, with complex interactions between height and radial growth.

GROWTH-RING DISTINCTNESS and BOUNDARY ANATOMY VARIABILITY in TROPICAL TREES [PDF]

, 2016
The phenomenon of distinct, absent or indistinct growth rings is a highly variable feature used for wood identification and a wide range of tree-ring studies. Causes for its variability are not yet fully understood.

Dendroarchaeology in Europe

Frontiers in Ecology and Evolution, 2022
Human evolution was strongly related to environmental factors. Woodlands and their products played a key role in the production of tools and weapons, and provided unique resources for constructions and fuel.

Missing rings in Pinus halepensis – the missing link to relate the tree-ring record to extreme climatic events

Frontiers in Plant Science, 2016
Climate predictions for the Mediterranean Basin include increased temperatures, decreased precipitation, and increased frequency of extreme climatic events (ECE).

Xylem features detrending methods matter: A case study on earlywood vessels of Fraxinus mandshurica

Ecological Indicators, 2021
Xylem anatomy can provide valuable information about tree allometry and ecophysiological performance. It has unique advantages in the study of global climate change and forest adaptation compared to traditional ring-width or density proxy parameters ...

Crossdating Juniperus procera from North Gondar, Ethiopia [PDF]

, 2010
The application of dendrochronology in (sub)tropical regions has been limited by the difficulty in finding trees with distinct annual rings that can be crossdated.
