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

open access: yesFrontiers 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

open access: yesFrontiers 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.

A century of tree line changes in sub-Arctic Sweden shows local and regional variability and only a minor influence of 20th century climate warming [PDF]

open access: yes, 2011
Aim Models project that climate warming will cause the tree line to move to higher elevations in alpine areas and more northerly latitudes in Arctic environments.

Dendroarchaeology in Europe

open access: yesFrontiers 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.

Frog origins: inferences based on ancestral reconstructions of locomotor performance and anatomy [PDF]

open access: yes, 2016
Frogs are the most species-rich and ecologically diverse group of amphibians and are characterized by a unique body plan including long legs, elongated ilia, and fused caudal vertebrae.

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

open access: yesFrontiers 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

open access: yesEcological 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 ...

A simple and cost-effective method for cable root detection and extension measurement in estuary wetland forests [PDF]

open access: yes, 2016
This work presents the development of a low-cost method to measure the length cable roots of black mangrove (Avicennia germinans) trees to define the boundaries of central part of the anchoring root system (CPRS) without the need to fully expose root ...

A multi-proxy framework to detect insect defoliations in tree rings: a case study on pine processionary

open access: yesFrontiers in Ecology and Evolution, 2023
Assessing and reconstructing the impacts of defoliation caused by insect herbivores on tree growth, carbon budget and water use, and differentiating these impacts from other stresses and disturbances such as droughts requires multi-proxy approaches. Here
