Tree-ring anatomy reflects the year-by-year impact of environmental factors on tree growth. Up to now, research in this field has mainly focused on the hydraulic architecture, with ray parenchyma neglected despite the growing recognition of its relevance for xylem function. Our aim was to address this gap by exploring the potential of the annual patterns of xylem parenchyma as a climate proxy. We constructed ring-width and ray-parenchyma chronologies from 1965 to 2004 for 20 Juniperus thurifera… Expand
Plasticity in xylem anatomical traits of two tropical species in response to intra-seasonal climate variability
TLDR
Results showed a significant correlation of EWV and FRV with mean accumulated precipitation during the summer season (DJF) and with mean temperature in December, indicating their great potential for dendroecological studies in subtropical regions. Expand
Tracheid anatomical responses to climate in a forest-steppe in Southern Siberia
TLDR
It is suggested that increasing drought stress might hamper the formation of a functional xylem structure, thus being a possible trigger for a miss-acclimation causing long-term decline and higher exposure to hydraulic failures. 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.

Xylem anatomical responses to climate variability in Himalayan birch trees at one of the world’s highest forest limit
TLDR
Results revealed that Himalayan birch is well adapted to the monsoon seasonality and is responding positively to atmospheric warming, thus suggesting the potential for this species to further expand in altitude under the forecasted climate change scenarios. Expand
Wood anatomical traits highlight complex temperature influence on Pinus cembra at high elevation in the Eastern Alps
TLDR
Analysis of xylem anatomical traits at intra-ring level and the use of daily temperature records proved to be useful for high resolution and detailed climate/growth association inferences in Pinus cembra. Expand
A 481-year chronology of oak earlywood vessels as an age-independent climatic proxy in NW Iberia
Abstract The earlywood vessels of ring-porous trees can be analyzed dendrochronologically and used as a proxy for environmental information. However, most works deal with the analysis of contemporaryExpand
Variability of ray anatomy of Larixgmelinii along a forest productivity gradient in Siberia
TLDR
This study quantifies how anatomical properties of rays—one of the main container for carbon reserves in tree stems—vary among sites, individuals, and annual rings of Larix gmelinii growing in contrasting sites in Siberia and suggests that the functional connection between the anatomy of rays and tracheid is unaffected by environment.

Assessing Conifer Ray Parenchyma for Ecological Studies: Pitfalls and Guidelines
TLDR
Evaluated rays in conifers and the presented guidelines regarding data accuracy as a function of measured wood surface and number of samples represent an important methodological reference for ray quantification, which will ultimately improve the understanding of the fundamental role of ray parenchyma tissue for the performance and survival of trees growing in stressed environments. Expand
Asynchronous leaf and cambial phenology in a tree species of the Congo Basin requires space-time conversion of wood traits.
TLDR
An integrated approach including high-resolution measurements of growth, stable isotopes and anatomical features allows exact dating of the formation of traits in the Congo Basin to explore the asynchrony of growth in a rainforest and contribute to understanding this aspect of forest resilience.

Wood Cellular Dendroclimatology: Testing New Proxies in Great Basin Bristlecone Pine
TLDR
Century-long time series of anatomical parameters developed for Great Basin bristlecone pine emerged as a reliable moisture indicator and was then used to reconstruct total March–August precipitation from 1870 to 2013, revealing a positive and temporally stable correlation of tracheid size with monthly precipitation.

Quantitative Tracheid Anatomy Reveals a Complex Environmental Control of Wood Structure in Continental Mediterranean Climate
TLDR
Tracheid anatomical variables improved the understanding of climate effects on tree growth and wood formation under harsh environmental conditions, as those experienced in continental Mediterranean climates, where limiting factors show multiple shifts across the year. Expand
Suitability of chestnut earlywood vessel chronologies for ecological studies.
TLDR
The work shows that the mean vessel size of the ring-porous chestnut contains ecophysiological information that can be used for research in dendrochronology. Expand
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
Distribution and vitality of xylem rays in relation to tree leaf area in douglas-fir
TLDR
There was a positive relationship between leaf area and the relative volume of ray in outer sapwood at breast height, supporting the hypothesis that Douglas-fir trees with larger leaf areas have higher ray volume than do trees with smaller leaf areas. Expand
The importance of early summer temperature and date of snow melt for tree growth in the Siberian Subarctic
Abstract. Wood material for at least 12 larch trees at six sites [Larix sibirica Ldb, Larix gmelinii (Rupr.) Rupr, Larix cajanderi Mayr] near the northern timberline in Siberia was analyzed toExpand
Sex-specific, age-dependent sensitivity of tree-ring growth to climate in the dioecious tree Juniperus thurifera.
TLDR
A significant interaction between age and sex is found in the climatic response of J. thurifera, with young females the most sensitive to summer water stress and that sex-related sensitivity to summer drought may be attributable to less efficient water use by females. Expand
Earlywood vessels of Castanea sativa record temperature before their formation.
TLDR
It is hypothesized that February and March temperatures affect cambial sensitivity to auxin, preconditioning tree responses later in the season, and April temperature is related to tree activation whereby new hormone production fosters vessel expansion. Expand
