Biocrust alone can be a stable state besides bare soil and vascular plant in global drylands.
Drought and salinity are major environmental stresses that impair crop growth productivity worldwide. Improving drought salt tolerance of crops with microbial mutualists is an effective environmentally sound strategy to meet the demands ever-growing world population. In present study, we found Streptomyces albidoflavus OsiLf-2, a moderately salt-tolerant endophytic actinomycete, produced abundant osmolytes, including proline, polysaccharides, ectoine. Inoculation OsiLf-2 increased...
<title>Abstract</title> Soil salinization poses a threat to global food security by deteriorating soil biodiversity and especially various functions. However, how affects the biodiversity-multifunctionality relationship remains largely unknown in agro-ecosystems. Here, we conducted standardized survey of agro-ecosystems across typical gradient at 115 representative agricultural sites, aiming investigate relationships between (encompassing diversity bacteria, fungi, archaea, protists,...
Abstract Although long‐term agricultural activity frequently decreases biodiversity, it remains unclear whether such biodiversity losses are readily reversible. There is no doubt that the important ecological function of seed bank memory, but few researchers have explored role banks in grassland ecosystem resilience and threshold theory. We used a space‐for‐time subrogation method, i.e., natural meadow (never farmed for moderate gazing) meadows 30 yr then abandoned 1, 10, 20 yr, to determine...
Climate change critically affects the carbon cycle of terrestrial ecosystems and thereafter climate-carbon feedback. Previous studies have addressed changes in temporal spatial distribution precipitation, termed as altered precipitation regimes. However, response to remain unclear. In this study, we used three process-based models investigate effect regimes on interannual variability (IAV) gross primary productivity (GPP), net ecosystem (NEP) respiration (RE). Annual sum (PRE) its monthly...
Under disease stress, activation of defense response in plants often comes with the cost a reduction growth and yield, which is referred as growth-defense trade-off. The microorganisms can be recruited by to mitigate trade-off are great value crop breeding.
Abstract Dryland ecosystems exist in various vegetation landscapes with contrasting compositions of vascular plants and biocrusts (surface‐soil mats comprised soil particles, cyanobacteria, lichens, mosses fungi), they are very vulnerable to ongoing global change. However, compared plants, the responses their coexistence change remain elusive. We conducted a 5‐year experiment involving multi‐level precipitation nitrogen addition desert shrubland northern China examine these responses. found...
This study determined the effect of temperament on antioxidant capacity and relationship between contents amino acids (AA) fatty (FA) in muscle Hu sheep. Organ samples five calm nervous sheep were collected to determine AA FA tissue. The concentrations malondialdehyde (MDA) superoxide excretion enzyme (SOD) intestinal tissue lower than those (p < 0.01), activity glutathione peroxidase (GSH-Px) liver was significantly higher that = 0.050). content sheep, especially reductive acids, which...
Wild-type p53-induced phosphatase 1 (Wip1), also termed PPM1D, is a member of the protein 2C family, which characterized by distinctive oncogenic properties. Overexpression Wip1 observed in certain types human tumors that are associated with significantly poor prognosis. The present study aimed to detect expression non‑small cell lung cancer (NSCLC) and analyze its prognostic value such patients. level was compared between NSCLC normal tissue specimens using immunohistochemistry, it found...
The Bayan Har Group in Quanshuigou area of the northern Tibetan Plateau is regionally subdivided into three litho‐stratigraphic units, namely, upper, middle, and lower formations. In this study, we report geochemical data for fine‐grained sandstones from upper formation aiming to constrain their source weathering, provenance, palaeoenvironment, tectonic setting. exhibit similar contents SiO 2 Al O 3 relative continental crust (UCC) Post‐Archean Australian Shale classified as wacke on log...
Abstract. Biological soil crusts (biocrusts hereafter) cover a substantial proportion of the dryland ecosystem and play crucial roles in ecological processes such as biogeochemical cycles, water distribution, erosion. Consequently, studying spatial distribution biocrusts holds great significance for drylands, especially on global scale, but it remains limited. This study aimed to simulate global-scale investigations biocrust by introducing three major approaches, namely spectral...
Abstract Intensified anthropogenic activities have drastically altered many ecosystems, motivating the use of restoration to regain key ecosystem functions and services stem biodiversity losses. Restoration is particularly difficult when human pushed an area into a new state with self‐reinforcing feedbacks. This study investigated long‐term project in dryland Tengger Desert northwestern China, initiated 1956. We analyzed shrub grass cover for 49 yr after installation infrastructure that...
In this study, gibberellic acid 3 (GA3) and uniconazole were applied as the means of improving cadmium (Cd) polluted site phytoremediation using maize (Zea mays L.).The results showed that GA3 (40 mg/L), (800 mg/L) could increase biomass, plant height, stem diameter, leaf area, root parameters plants under Cd stress (0.4 by foliar spraying.GA3 SPAD value leaves 23.45% net photosynthetic rate 645.93%.Both regulators alleviate oxidative damage activity SOD POD up to 11.44~58.41%and...
In the past few decades, industrialization has caused a large number of pollutants to be released into atmosphere. Forest ecosystems play an important function in regulating biogeochemistry and circulation metal ions pollutants. affect absorption dissolution nutrients from atmosphere vegetation canopy, thereby influencing content composition forest floor leachate soil solution. This study examined changes acid anions (NO3−, SO42−, Cl−) cations (K+, Ca2+, Na2+, Mg2+, Fe3+, Pb2+, Cu2+, Cd2+)...
Ecosystems may exhibit transient (the period toward stable state) and alternative states, where positive feedback(s) generally plays important roles. However, the outline between states blur when involving multiple feedbacks, which shift dominance along environmental gradient. Therefore, a common theoretical framework considering feedbacks is needed. Specifically, this study employed mechanic model to explain long state of dryland ecosystem after restoration under effects two feedbacks. We...
Ecosystems can exhibit rich equilibrium behaviors, including alternative stable states (ASS), for which ecosystems dramatically differ in structure and functions. Therefore, it is critical to understand system behavior. Positive feedback has been recognized as a process induce ASS. However, largely unclear whether extent increasing number of positive feedbacks will be easier produce Using generalized Lotka-Volterra model two functional forms feedback, this study found that was necessary ASS,...
Precipitation regime has been dramatically shifted under global warming, and will especially reshape the water-limited dryland ecosystems, biomes therein. Among biological organisms, biocrust (complex communities consisting of soil particles, photoautotrophic (algae, cyanobacteria, lichens, mosses), heterotrophic (e.g., bacteria, fungi, archaea) organisms) is a critical component, tends to be fragile relative vascular plants. However, it remains largely unclear how do different types respond...
The extensive afforestation efforts on the Loess Plateau, incurring hundreds of billions CNY, trigger heightened vegetation cover, depleting soil water, and imperiling ecosystem sustainability. Widespread debate persists over feasibility optimal locations for afforestation. However, what has been overlooked is potential presence alternative stable states within ecosystems, a captivating system equilibrium behavior. This study integrates remote sensing, minimal model, environmental data to...
