The expansion of the oil palm industry in Indonesia has improved livelihoods rural communities, but comes at cost biodiversity and ecosystem degradation. Here, we investigated ways to balance ecological economic outcomes cultivation. We compared a wide range production systems, including smallholder plantations, industrialized company estates, estates with agronomic management, native tree enrichment. Across all management types, assessed multiple indicators biodiversity, functions,...
Worldwide, forests are increasingly exposed to extreme droughts causing tree mortality. Because of the complex nature mechanisms involved, various traits have been linked drought responses with contrasting results. This may be due species-specific strategies in regulating water potential, a process that unfolds two distinct phases: first phase until stomatal closure, and second reaching lethal xylem hydraulic thresholds. We conducted dry-down experiments five broadleaved temperate species...
Plant transpiration is a key element in the hydrological cycle. Widely used methods for its assessment comprise sap flux techniques whole-plant and porometry leaf stomatal conductance. Recently emerging approaches based on surface temperatures wide range of machine learning offer new possibilities to quantify transpiration. The focus this study was predict conductance drone-recorded meteorological data compare these predictions with in-situ measured To build prediction models, we applied...
The efficiency of the water transport system in trees sets physical limits to their productivity and use. Although coordination carbon assimilation hydraulic functions has long been documented, mutual inter-relationships between wood anatomy, use have not yet jointly addressed comprehensive field studies. Based on observational data from 99 Indonesian rainforest tree species 37 families across 22 plots, we analyzed how anatomy sap flux density relate size density, tested combined influence...
Water-use efficiency (WUE) is affected by multiple leaf traits, including stomatal morphology. However, the impact of morphology on WUE across different ontogenetic stages tree species not well-documented. Here, we investigated relationship between morphology, intrinsic water-use (iWUE) and carbon isotope ratio (δ
With the prospect of climate change and more frequent El Niño-related dry spells, drought tolerance oil palm (Elaeis guineensis Jacq.), one most important tropical crop species, is major concern. We studied influence soil water availability height on plasticity xylem anatomy fronds their embolism resistance at well-drained seasonally flooded riparian sites in lowland Sumatra, Indonesia. found overall mean P12 P50 values, i.e., pressures 12% or 50% loss hydraulic conductance, -1.05 - 1.86...
Water-use efficiency (WUE) is affected by multiple leaf traits, including stomatal morphology. However, the impact of morphology on WUE across different ontogenetic stages tree species not well-documented. Here, we investigated relationship between intrinsic water-use (iWUE=A/gs) and carbon isotope ratio (δ13C). We sampled 190 individuals juvenile mature trees belonging to 18 temperate broadleaved 9 genera. measured guard cell length (GCL), density (SD), specific area (SLA), gas-exchange,...
Abstract The predicted increase of drought intensity in South-East Asia has raised concern about the sustainability rubber (Hevea brasiliensis Müll. Arg.) cultivation. In order to quantify degree phenotypic plasticity this important tree crop species, we analysed a set wood and leaf traits related hydraulic safety efficiency PB260 clones from eight small-holder plantations Jambi province, Indonesia, representing gradient local microclimatic edaphic conditions. Across plots, branch embolism...
The evolution of the internal water transport system was a prerequisite for high plant productivity. In times climate change, understanding dependency juvenile growth on xylem hydraulic physiology is therefore importance. Here, we explored various wood anatomical, hydraulic, and leaf morphological traits related to safety efficiency in three temperate broadleaved tree species (Acer pseudoplatanus, Betula pendula, Sorbus aucuparia). We took advantage severe natural heat wave that resulted...
Abstract Vessel diameter variation along the hydraulic pathway determines how much water can be moved against force of gravity from roots to leaves. While it is well-documented that tree size scales with vessel at stem base due effect basipetal widening, less known whether this likewise applies terminal sun-exposed twigs. To analyze height on twig xylem anatomy, we compiled data for 279 tropical rainforest species belonging 56 families in lowlands Jambi Province, Indonesia. Terminal...
