Studying global change through investigation of the plastic responses of xylem anatomy in tree rings.
TLDR
It is believed that the study of tree-ring anatomy is emerging as a promising approach in tree biology and climate change research, particularly if complemented by physiological and ecological studies. Expand
Distilling allometric and environmental information from time series of conduit size: the standardization issue and its relationship to tree hydraulic architecture.
TLDR
This article synthesizes current knowledge on the biophysical and physiological mechanisms influencing the short- to long-term variation in the most widely used wood-anatomical feature, namely conduit size and clarifies the strong mechanistic link between conduit-lumen size, tree hydraulic architecture and height growth. Expand
New star on the stage: amount of ray parenchyma in tree rings shows a link to climate.
TLDR
Ring-width and ray-parenchyma-based chronologies have potential to complement ring-width chronologies as a tool for climate reconstructions and medium- and low-frequency signals in the variation of ray parenchyma may improve understanding of how trees respond to environmental fluctuations and to global change. Expand
Retrospective Analysis of Wood Anatomical Traits Reveals a Recent Extension in Tree Cambial Activity in Two High-Elevation Conifers
TLDR
A novel retrospective approach is applied to test the long-term consistency in the timing of onset and ending of cambial activity, and in the maximum cambia cell division rate in two conifer species, European larch and Norway spruce at high-elevation in the Alps, to improve the understanding of tree responses to climate variability in both the short- and long- term context. Expand
Quantitative Wood Anatomy—Practical Guidelines
TLDR
Following a rigid protocol and quality control as proposed in this paper is thus mandatory to use quantitative data of xylem anatomical features as a powerful source for many research topics. Expand
How does climate influence xylem morphogenesis over the growing season? Insights from long-term intra-ring anatomy in Picea abies
TLDR
The distinct climate impacts on cell enlargement and wall thickening indicate that different morphogenetic mechanisms are responsible for different tracheid traits, and can support and extend short-term xylogenesis observations. Expand
Growth Increment Patterns in the Roots of Two Alpine Forbs Growing in the Center and at the Periphery of a Snowbank
TLDR
The results suggest that effects of climatic fluctuations on plant growth can be amplified in snowbanks and that there may be favorable growth conditions initially at the periphery of a snowbank that are compensated for in the center of the snowbank, in the long run, by continuously low-competition growth conditions. Expand
Wood structural differences between northern and southern beech provenances growing at a moderate site.
TLDR
Compared the radial growth, wood-anatomical traits and leaf phenology of four beech provenances originating from southern and northern locations and planted in a provenance trial in the Netherlands, it is concluded that the similarity in ring-width variation among provenances points to environmental control of this trait. Expand
Evidence for life history changes in high-altitude populations of three perennial forbs.
TLDR
Data for three ecologically distinct forb species provide evidence of a consistent shift toward more conservative and strongly constrained life histories at higher altitudes and indicate the possible importance of changes in selection pressures across strong environmental gradients on life history strategies within a single species. Expand
New research perspectives from a novel approach to quantify tracheid wall thickness
TLDR
Cell wall thickness measurements performed with a novel approach to measure tracheid CWT in high-resolution images of wood cross-sections showed comparable accuracy for several image resolutions, with an optimal accuracy-efficiency balance at 100× magnification. Expand
