Terrestrial carbon stock mapping is important for the successful implementation of climate change mitigation policies. Its accuracy depends on availability reliable allometric models to infer oven-dry aboveground biomass trees from census data. The degree uncertainty associated with previously published pantropical allometries large. We analyzed a global database directly harvested at 58 sites, spanning wide range climatic conditions and vegetation types (4004 ≥ 5 cm trunk diameter). When...
A review of stem volume and biomass equations for tree species growing in Europe is presented. The mathematical forms the empirical models, associated statistical parameters information about size trees country origin were collated from scientific articles technical reports. total number compiled estimation was 607 prediction it 230. analysis indicated that most developed aboveground components. relatively small southern Europe. Most based on a few sampled sites with very limited trees....
Summary The evolution of lignified xylem allowed for the efficient transport water under tension, but also exposed vascular network to risk gas emboli and spread between conduits, thus impeding sap leaves. A well‐known hypothesis proposes that safety (its ability resist embolism formation spread) should trade off against efficiency capacity water). We tested this safety–efficiency in branch across 335 angiosperm 89 gymnosperm species. Safety was considered at three levels: potentials where...
Summary Plant function requires effective mechanisms to regulate water transport at a variety of scales. Here, we develop new theoretical framework describing plant responses drying soil, based on the relationship between midday and predawn leaf potentials. The intercept (Λ) characterizes maximum transpiration rate per unit hydraulic capacity, whereas slope (σ) measures relative sensitivity conductance declining availability. This was applied newly compiled global database potentials...
Stomatal regulation presumably evolved to optimize CO2 for H2 O exchange in response changing conditions. If the optimization criterion can be readily measured or calculated, then stomatal responses efficiently modelled without recourse empirical models underlying mechanism. Previous efforts have been challenged by lack of a transparent index cost losing water. Yet it is accepted that stomata control water loss avoid excessive hydraulic conductance from cavitation and soil drying. Proximity...

Abstract. Forest ecosystem models based on heuristic water stress functions poorly predict tropical forest response to drought partly because they do not capture the diversity of hydraulic traits (including variation in tree size) observed forests. We developed a continuous porous media approach modeling plant hydraulics which all parameters constitutive equations are biologically interpretable and measurable (e.g., turgor loss point πtlp, bulk elastic modulus ε, capacitance Cft, xylem...
Trait variability in space and time allows plants to adjust changing environmental conditions. However, we know little about how this is distributed coordinated at different organizational levels. For six dominant tree species northeastern Spain (three Fagaceae three Pinaceae) quantified the inter- intraspecific of a set traits along water availability gradient. We measured leaf mass per area (LMA), nitrogen (N) concentration, carbon isotope composition leaves (δ13 C), stem wood density,...
Land surface models (LSMs) typically use empirical functions to represent vegetation responses soil drought. These largely neglect recent advances in plant ecophysiology that link xylem hydraulic functioning with stomatal climate. We developed an analytical optimization model based on hydraulics (SOX) predict Coupling SOX the Joint UK Environment Simulator (JULES) LSM, we conducted a global evaluation of against leaf- and ecosystem-level observations. simulates leaf conductance climate for...
Abstract Heatwaves exert disproportionately strong and sometimes irreversible impacts on forest ecosystems. These remain poorly understood at the tree species level across large spatial scales. Here, we investigate effects of record-breaking 2018 European heatwave growth water status using a collection high-temporal resolution dendrometer data from 21 53 sites. Relative to two preceding years, annual stem was not consistently reduced by but stems experienced twice temporary shrinkage due...
Abstract Non-structural carbohydrates (NSC) are major substrates for plant metabolism and have been implicated in mediating drought-induced tree mortality. Despite their significance, NSC dynamics tropical forests remain little studied. We present leaf branch data 82 Amazon canopy species six sites spanning a broad precipitation gradient. During the wet season, total (NSC T ) concentrations both organs were remarkably similar across communities. However, its soluble sugar (SS) starch...
Tree species display a wide variety of water-use strategies, growth rates and capacity to tolerate drought. However, if we want forecast cope with increasing aridity drought, need identify which measurable traits confer resilience drought across species. Here, use global tree ring network (65 species; 1931 site series ring-width indices-RWI) evaluate the relationship long-term growth-drought sensitivity (RWI-SPEI index relationship) short-term response extreme episodes (resistance, recovery...
