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....
Wood density is a fundamental property related to tree biomechanics and hydraulic function while playing crucial role in assessing vegetation carbon stocks by linking volumetric retrieval mass estimate. This study provides high-resolution map of the global distribution wood at 0.01° (~1 km) spatial resolution, derived from four decision trees machine learning models using database 28,822 tree-level measurements. An ensemble top-performing combined with eight cross-validation strategies shows...
Tree rings are natural archives of climate and environmental information with a yearly resolution. Indeed, wood anatomical, chemical other properties tree synthesis several intrinsic, factors, interconnected processes acting during growth. In particular, Intra-Annual Density Fluctuations (IADFs) can be considered as tree-ring anomalies that used to better understand growth reconstruct past conditions intra-annual However, the ecophysiological behind IADF formation, well their functional...
Juniperus thurifera L. is an important tree endemic to the western Mediterranean basin that it able grow in semi-arid climates. It nowadays exhibits a disjunct distribution pattern, occurring North Africa, Spain, France and Italian Alps. The Strait of Gibraltar has acted as efficient barrier against gene flow between African European populations, which are considered different subspecies by some authors. We aimed at describing intraspecific genetic diversity J. populations from Iberian...
Intra-annual density fluctuations (IADFs) are anatomical features formed in response to changes the environmental conditions within growing season. These commonly observed Mediterranean pines, being more frequent younger and wider tree rings. However, process behind IADF formation is still unknown. Weekly monitoring of cambial activity wood would fill this void. Although studies describing have become frequent, knowledge fragmentary region. Here we present data from two diameter classes...
Tree rings provide information about the climatic conditions during growing season by recording them in different anatomical features, such as Intra-Annual Density Fluctuations (IADFs). IADFs are intra-annual changes of wood density appearing latewood-like cells within earlywood, or earlywood-like latewood. The occurrence is dependent on age and size tree, it triggered drivers. variations IADF frequency species their dependence climate across a wide geographical range have still to be...
Tree-ring width integrates the prevailing environmental conditions during whole growing season (annual resolution). Other wood anatomical traits, like intra-annual density fluctuations (IADFs), imprint within (sub-annual IADFs are anatomically characterized by latewood-like cells earlywood or earlywood-like latewood. Under climate change scenarios, it is increasingly important to understand which traits more relevant in adjustment of long-lived species. We established a latitudinal transect...
The formation of wood results from cambial activity and its anatomical properties reflect the variability environmental conditions during growing season. Recently, it was found that density variations in conifers under cold-limited environment result adjustment cell wall thickness (CWT) to temperature. Additionally, is known intra-annual fluctuations (IADFs) are formed response precipitation after summer drought. Although IADFs frequent Mediterranean no study has yet been conducted determine...
Despite growing interest in predicting plant phenological shifts, advanced spring phenology by global climate change remains debated. Evidence documenting either small or large advancement of to rising temperature over the spatio-temporal scales implies a potential existence thermal threshold responses forests warming. We collected unique data set xylem cell-wall-thickening onset dates 20 coniferous species covering broad mean annual (MAT) gradient (-3.05 22.9°C) across Northern Hemisphere...
