Phenols are ubiquitous environmental pollutants, whose biotransformation involving phenol coupling catalyzed by cytochromes P450 may produce more lipophilic and toxic metabolites. Density functional theory (DFT) computations were performed to explore the debated phenol-coupling mechanisms, taking triclosan as a model substrate. We find that diradical pathway facilitated compound I protonated II of is favored vs alternative radical addition or electron-transfer mechanisms. The identified...
Abstract Hydraulic failure caused by severe drought contributes to aboveground dieback and whole‐plant death. The extent which or death can be predicted plant hydraulic traits has rarely been tested among species with different leaf habits and/or growth forms. We investigated 19 in 40 woody a tropical savanna their potential correlations response during an extreme event the El Niño–Southern Oscillation 2015. Plant trait variation was partitioned substantially habit but not form along...
Vulnerability segmentation, the condition under which plant leaves are more vulnerable to drought-induced cavitation than stems, may act as a "safety valve" protect stems from hydraulic failure. Evergreen, winter-deciduous, and drought-deciduous tree species co-occur in tropical savannas, but there have been no direct studies on role of vulnerability segmentation stomatal regulation maintaining safety trees with these three leaf phenologies. To this end, we selected Anacardiaceae...
Abstract Savanna ecosystems play a crucial role in the global carbon cycle. However, there is gap our understanding of fluxes savanna Southeast Asia. In this study, eddy covariance technique (EC) and biometric-based method (BM) were used to determine exchange ecosystem Southwest China. The BM-based net production (NEP) was 0.96 tC ha −1 yr . EC-based estimates average annual gross primary productivity (GPP), respiration (R eco ), (NEE) 6.84, 5.54, −1.30 , respectively, from May 2013 December...
Abstract Legumes account for a significant proportion of plants in the terrestrial ecosystems. Nitrogen (N)-fixing capability certain legumes is pivotal trait that contributes to their ecological dominance. Yet, functional traits and relationships between N-fixer non-N-fixer are poorly understood. Here, we investigated 27 associated with morphology, nutrients, hydraulic conductance photosynthesis 42 woody (19 N-fixers 23 non-N-fixers) common garden. Our results showed had higher specific...
Summary The decomposition of wood inside living tree hollows influences forest structure and processes. Although the rate controls formation hollows, it has not previously been measured. In an old‐growth subtropical montane evergreen broad‐leaved in south‐west China, we measured respiration rates decaying logs (downed trunks) snags (standing dead trees) using infrared CO 2 analysis. We compared stem radial growth to horizontal expansion hollows. also estimated proportion total volume time...
Pesticide biotransformation, especially by cytochrome P450 enzymes (CYPs), may produce metabolites with substantially altered toxicological and physicochemical profiles, which has drawn great attention as a basis for environmental risk assessment. CYPs are active in the metabolism of various reactions pesticides, there potentially different short-lived oxidant species (Compound I vs Compound 0), make elucidating their biotransformation mechanism challenging. To facilitate this task, we...
Abstract Evergreen and deciduous species coexist in tropical dry forests savannas, but differ physiological mechanisms life-history strategies. Hydraulic conductivity mechanical support are two major functions of the xylems woody plant related to growth survival. In this study, we measured sapwood-specific hydraulic (Ks), leaf-specific (KL), modulus rupture (MOR) elasticity (MOE), xylem anatomical traits fiber contents 20 with contrasting leaf phenology (evergreen vs deciduous) a Chinese...
Abstract Ecosystem light use efficiency (LUE) is a critical parameter in estimating CO 2 uptake by vegetation from climatological and satellite data. However, the spatiotemporal dynamics biophysical regulations of ecosystem‐level LUE are not well understood, resulting large uncertainties estimation gross primary productivity (GPP) using LUE‐based models. In this study, we used eddy covariance to explore variations controls four contrasting forest ecosystems (savanna, tropical rainforest,...
Abstract The geographical variation and domestication of tree species are an important part the theory forest introduction, tracing germplasm is theoretical basis for establishment high‐quality plantations. Chinese pine ( Pinus tabuliformis Carr . ) native timber widely distributed in northern China, but it unclear exactly where main plantation populations originated. Here, using two mtDNA markers, we analyzed 796 individuals representing 35 (matR marker), 873 38 (nad5‐1 marker) major...
Soil microorganisms play important roles in nutrient mobilization and uptake of mineral nutrition plants. Agricultural management, such as soil sterilization, can have adverse effects on plant growth because the elimination indigenous microorganisms. Arbuscular mycorrhizal (AM) fungi are one most beneficial for growth. However, whether AM compensate loss microbial communities to support metabolism is largely unknown. In this study, a pot experiment was conducted investigate secondary...
Abstract Water stored in trunk sapwood is vital for the canopy to maintain its physiological function under high transpiration demands. Little known regarding anatomical properties that contribute hydraulic capacitance of tree trunks and whether correlated with gas exchange traits branches. We examined capacitance, xylem characteristics trunks, embolism resistance, minimal water potential branches, leaf photosynthesis stomatal conductance 22 species from a tropical seasonal rainforest...
Abstract Liana abundance and biomass are increasing in neotropical Asian tropical seasonal forests over the past decades. Stem mechanical properties hydraulic traits influence growth survival of plants, yet differences stem performance between congeneric lianas trees remain poorly understood. Here, we measured 11 for 10 liana species tree from Bauhinia grown a common garden. Our results showed that possessed lower strength as indicated by both modulus elasticity rupture, higher potential...
Leaf nutrient resorption and drought resistance are crucial for the growth survival of plants. However, our understanding relationships between leaf plant is still limited. In this study, we investigated nitrogen phosphorus efficiencies (NRE PRE), structural traits, osmotic potential at full hydration (Ψosm), xylem water 50% loss xylem-specific hydraulic conductivity (P50) seasonal minimum (Ψmin) 18 shrub tree species in a semiarid savanna ecosystem, Southwest China. Our results showed that...
Vulnerability segmentation (VS) has been widely suggested to protect stems and trunks from hydraulic failure during drought events. In many ecosystems, some species have shown be non-segmented (NS species). However, it is unclear whether drought-induced mortality related VS. To understand this, we surveyed the recruitment rate measured traits of leaves as well photosynthesis six tree over five years (2012–2017) in a savanna ecosystem Southwest China. Our results showed that NS exhibited...
We examined the relationship between density of cavity trees and forest structure characteristics explored occurrence among different tree species diameter breast height (DBH) size in a subtropical evergreen broad-leaved Ailao Mountains southwestern China. Cavity accounted for 7.9% living 16.3% dead trees. Average (86.3 trees·ha –1 ) was 6.9 times that Density positively correlated with showed skewed distribution DBH classes peaked at DBHs 20–40 cm. Moreover, probability cavity-bearing...
To determine the invasiveness of invasive plants, many studies have compared photosynthetic traits or strategies between and native species. However, few dynamics species during light fluctuations. We induction, relaxation leaf species,
