Abstract The interaction between xylem phenology and climate assesses forest growth productivity carbon storage across biomes under changing environmental conditions. We tested the hypothesis that patterns of wood formation are maintained unaltered despite temperature changes cold ecosystems. Wood microcores were collected weekly or biweekly throughout growing season for periods varying 1 13 years during 1998–2014 cut in transverse sections assessing onset ending phases differentiation. data...
Abstract The growth of past, present, and future forests was, is will be affected by climate variability. This multifaceted relationship has been assessed in several regional studies, but spatially resolved, large-scale analyses are largely missing so far. Here we estimate recent changes 5800 beech trees ( Fagus sylvatica L.) from 324 sites, representing the full geographic climatic range species. Future trends were predicted considering state-of-the-art scenarios. validated models indicate...
Significance Forest trees can live for hundreds to thousands of years, and they play a critical role in mitigating global warming by fixing approximately 15% anthropogenic CO 2 emissions annually wood formation. However, the environmental factors triggering formation onset springtime cellular mechanisms underlying this remain poorly understood, since forms beneath bark is difficult monitor. We report that Northern Hemisphere conifers driven primarily photoperiod mean annual temperature....
An age effect on growth trends and climate/growth relationships of trees can possibly be discovered by analysing the seasonal dynamics xylem development. The aims this study, therefore, were to compare formation young (43 ± 4 years) old (162 26 Smith fir (Abies georgei var. smithii (Viguie & Gaussen) W. C. Cheng L. K. Fu) in Sygera Mountains, south-eastern Tibetan Plateau and, identify association between wood climate. radial was monitored microcores collected at weekly intervals during two...
Abstract The phenology of wood formation is a critical process to consider for predicting how trees from the temperate and boreal zones may react climate change. Compared leaf phenology, however, determinism still poorly known. Here, we compared first time three alternative ecophysiological model classes ( threshold models, heat‐sum models chilling‐influenced models) an empirical in their ability predict starting date xylem cell enlargement spring, four major Northern Hemisphere conifers...
Climate change is predicted to affect tree growth due increased frequency and intensity of extreme events such as ice storms, droughts heatwaves. Yet, there still a lot uncertainty on how trees respond an increase in events. Use both ground-based wood increment (i.e. ring width) remotely sensed data vegetation indices) can be used scale-up ground measurements, where link between the two, but this has only been demonstrated few studies. We tree-ring together with crown features derived from...
European beech Fagus sylvatica and Sessile oak Quercus petraea are reaching the north-eastern limits of their natural ranges in northern Poland. According to projected changes potential this region, climatic conditions for both species until 2080 will remain stable. On other hand, a decrease vitality mature trees reduction radial growth currently observed. To understand these contradictory findings, we monitored cambial activity during two vegetation seasons. 2015 was characterized by...
Despite its major economic importance and the vulnerability of Picea abies (L.) H. Karst. to climate change, how radial growth at intra-annual resolution is influenced by weather conditions in forest stands with a high production capacity has scarcely been explored. Between 2009 2011, phenological variation seasonal cambial cell (CP) was analysed adult P. trees from three contrasting sites, differing altitude latitude. The results indicate that timing CP highly synchronic process within...
There is limited information on intra-annual plasticity of secondary tissues tree species growing under different environmental conditions. To increase the knowledge about growth, which allows trees to adapt specific local climatic regimes, we examined climate–radial growth relationships Norway spruce (Picea abies (L.) H. Karst.) from three contrasting locations in temperate zone by analyzing tree-ring widths for period 1932–2010, and cell characteristics xylem phloem increments formed years...
Wood formation in European beech (Fagus sylvatica L.) and Scots pine (Pinus sylvestris was intra-annually monitored to examine plastic responses of the xylem phenology according altitude one southernmost areas their distribution range, i.e., Moncayo Natural Park, Spain. The monitoring done from 2011 2013 at 1180 1580 m a.s.l., corresponding lower upper limits forest this region.

We explored the inter-individual variability in bud-burst and its potential drivers, homogeneous mature stands of temperate deciduous trees. Phenological observations leaves wood formation were performed weekly from summer 2017 to 2018 for pedunculate oak, European beech silver birch Belgium. The was correlated previous' year autumn phenology (i.e. onset leaf senescence cessation formation) tree size but with important differences among species. In fact, primarily related senescence, height...
To understand better the adaptation strategies of intra-annual radial growth in Pinus halepensis and sylvestris to local environmental conditions, we examined seasonal rhythm cambial activity cell differentiation at tissue cellular levels. Two contrasting sites differing temperature amount precipitation were selected for each species, one typical their other represented border climatic where two species coexisted. Mature P. trees from Mediterranean (Spain) sub-Mediterranean (Slovenia) sites,...
Cessation of xylem formation or wood growth (CWG) and onset foliar senescence (OFS) are key autumn phenological events in temperate deciduous trees. Their timing is fundamental for the development survival trees, ecosystem nutrient cycling seasonal exchange matter energy between biosphere atmosphere, affects impact feedback forests to global change. A large-scale experimental effort improved observational methods have allowed us compare CWG OFS different tree species Western Europe,...
Abstract The effects of short‐term extreme events on tree functioning and physiology are still rather elusive. European beech is one the most sensitive species to late frost water shortage. We investigated intra‐annual C dynamics in stems under such conditions. Wood formation stem CO 2 efflux were monitored a Mediterranean forest for 3 years (2015–2017), including (2016) summer drought (2017). reduced radial growth and, consequently, amount carbon fixed biomass by 80%. Stem dioxide 2016 was...
European beech ( Fagus sylvatica L.) adapts to local growing conditions enhance its performance. In response variations in climatic conditions, trees adjust leaf phenology, cambial and wood formation patterns, which result different tree-ring widths (TRWs) anatomy. Chronologies of tree ring width vessel features [i.e., mean area (MVA), density (VD), relative conductive (RCTA)] were produced for the 1960–2016 period three sites that differ regimes spring phenology (two early- one...
