Abstract Climate is predicted to change over the 21st century. However, little known about how climate can affect soil phosphorus (P) cycle and availability in global terrestrial ecosystems, where P a key limiting nutrient. With database of Hedley fractions key‐associated physiochemical properties 760 (seminatural) natural soils compiled from 96 published studies, this study evaluated pattern affected ecosystems. Overall, available P, indexed by labile inorganic fraction, significantly...
Abstract Phosphorus limitation on terrestrial plant growth is being incorporated into Earth system models. The global pattern of phosphorus limitation, however, remains unstudied. Here, we examined the global‐scale latitudinal by analysing a total 1068 observations aboveground production response to additions at 351 forest, grassland or tundra sites that are distributed globally. observed phosphorus‐addition effect varied greatly (either positive negative), depending significantly upon...
Abstract The soil nitrogen (N) and phosphorus (P) availability often constrains carbon (C) pool, elevated N deposition could further intensify P limitation, which may affect C cycling in these N‐rich P‐poor ecosystems. Soil microbial residues not only organic (SOC) pool but also impact SOC stability through aggregation. However, how nutrient aggregate fractions the residue contribution to is still well understood. We took advantage of a 10‐year field fertilization experiment investigate...
Abstract Increasing atmospheric nitrogen (N) deposition could profoundly impact community structure and ecosystem functions in forests. However, conventional experiments with understory addition of N (UAN) largely neglect canopy-associated biota processes therefore may not realistically simulate to generate reliable impacts on forest ecosystems. Here we, for the first time, designed a novel experiment canopy (CAN) vs. UAN reviewed merits pitfalls two approaches. The following hypotheses will...
Summary Plant elemental properties are fundamentally important for physiology and biogeochemical cycling in ecosystems. No study has examined foliar elements their interaction with soil climate conditions at large geographic scales Karst areas of China, a biodiversity hotspot the world. Yet such information is understanding functional diversity nutrient strategies physiological adaptations plants to climatic edaphic heterogeneity. We assessed influence phylogeny, type on leaf element...
Abstract Understanding the soil phosphorus (P) cycle is a prerequisite for predicting how environmental changes may influence dynamics and availability of P in soil. We compiled database fractions sequentially extracted by Hedley procedure its modification 626 unfertilized uncultivated soils worldwide. With this database, we applied structural equation modeling to test hypothetical transformation models quantify importance different pools pathways shaping at global scale. Our revealed that...
In the severe pollution area of nanoplastics (NPs) and cadmium ions (Cd2+), joint effects their high environmental concentrations on primary producers may differ from those low doses. Thus, we investigated physiological changes, cell morphology, molecular dynamic simulation, phenotypic interactions, metabolomics responses C. pyrenoidosa to NPs Cd2+ after 12-d acclimation. After cultivation, mono-NPs mono-Cd2+ reduced density triggered antioxidant enzymes, extracellular polymeric substances...
Abstract Globally increased nitrogen (N) to phosphorus (P) ratios (N/P) affect the structure and functioning of terrestrial ecosystems, but few studies have addressed variation foliar N/P over time in subtropical forests. Foliar indicates N versus P limitation ecosystems. Quantifying long‐term dynamics their potential drivers is crucial for predicting nutrient status forest ecosystems under global change. We detected temporal trends N/P, quantitatively estimated interaction between plant...
The upper layer of forest soils (0-20 cm depth) were collected from urban, suburban, and rural areas in the Pearl River Delta Southern China to estimate distribution possible sources polycyclic aromatic hydrocarbons (PAHs). Total concentrations PAHs decreased significantly along urban-suburban-rural gradient, indicating influence anthropogenic emissions on PAH soils. High low molecular weight dominated urban soils, respectively, implying difference emission between areas. values isomeric...
Soil extractable nitrate, ammonium, and organic nitrogen (N) are essential N sources supporting primary productivity regulating species composition of terrestrial plants. However, it remains unclear how plants utilize these surface-earth environments regulate plant utilization. Here, we establish a framework to analyze observational data natural isotopes in soils globally, quantify fractional contributions soil nitrate (f
The burrow microhabitats created by burrowing mammals, as a hotspot for biodiversity distribution in ecosystems, provide multiple critical resources many other sympatric species. However, the cascading effects of on animal community assemblages and interspecific interactions are largely unknown. During 2020-2023, we monitored 184 Chinese pangolin (Manis pentadactyla) burrows using camera traps to reveal utilization patterns commensal We totally recorded up 57 species, with 19 mammal 32 bird...
It is well-known that drought has considerable effects on plant traits from leaf to ecosystem scales; however, little known about the relative contributions of various within or between tree species in determining plant's sensitivity tolerance under field conditions. We conducted a throughfall exclusion experiment simulate short-term (~67% during dry season October March) and prolonged prolonging May) understand two dominant (Michelia macclurei Schima superba) subtropical forests southern...
Abstract Impacts of nitrogen (N) enrichment on soil carbon (C) budgets in terrestrial ecosystems have been well documented by numerous field experiments and syntheses. Although previous studies largely attributed this phenomenon to the increased organic C inputs, potential mechanisms how N increases (SOC) remain contentious. In study, we conducted a meta‐analysis comprising 234 published N‐addition from multiple across China evaluate impacts SOC budget. revealed that significantly enhanced...
Abstract Atmospheric nitrogen (N) deposition has substantial effects on forest ecosystems. The of N understorey plants have been simulated by spraying the floor. Such addition (UAN) might simulate atmospheric in a biased manner, because it bypasses canopy. We compared UAN and canopy (CAN) at 0, 25 50 kg ha −1 year –1 SLA, leaf construction costs (CC), concentrations carbon ([C]), ([N]), phosphorus ([P]), minerals ([Mineral]), nitrate ([ ]), lignin ([Lignin]), lipids ([Lipid]), organic acids...
Abstract Molybdenum (Mo) is a key cofactor in enzymes used for nitrogen (N) fixation and nitrate reduction, the low availability of Mo can constrain N inputs, affecting ecosystem productivity. Natural atmospheric aerosolization deposition from sources such as desert dust, sea‐salt spray, volcanoes affect function across long timescales, but anthropogenic activities combustion, motor vehicles, agricultural dust have accelerated natural cycle. Here we combined synthesis global concentration...
