Abstract Ecological stoichiometry is an important approach to understand plant nutrient cycling and balance in the forest ecosystem. However, understanding of stoichiometric patterns through leaf‐litter‐soil system Mongolian pine among different stand origins still scarce. Therefore, reveal variations carbon (C), nitrogen (N), phosphorus (P) homeostasis origins, we measured C, N, P concentrations leaves, litter, soil, analyzed resorption efficiencies leaves differently aged plantations...

Due to their simple layout and adaptability various environments, straw checkerboards are widely used control windblown sand in China. To fully understand the wind proofing sand-fixing benefits of different board specifications, determine restorative effects checkerboard, we tested sizes determined performance as a windbreak trapping shifting sand, constructed models based on tunnel tests, enabling speed flow field be analysed. We also sampled soil areas where had been established for...

Climate change has intensified the frequency of extreme drought events in desert ecosystems, accompanied by uneven distribution annual precipitation. Whether precipitation at different phenophases have equivalent impacts on plants is an unverified topic, yet it crucial for understanding mechanisms vegetation adaptation to changes This study focuses typical plant Artemisia ordosica and employs situ control experiments using rain shelters simulate (30 consecutive days removal) three...

China, home to over 250 million children, has witnessed remarkable economic development in recent decades, successfully addressing many issues related basic hygiene and sanitation thereby altering the childhood disease spectrum. However, emergence of environment-related disorders among children become a significant concern. Despite rapid accumulation scientific knowledge on adverse effects environmental pollution child health, availability children-specific protective strategies actions...

Background Biological soil crusts are common components of desert ecosystem; they cover ground surface and interact with topsoil that contribute to desertification control degraded land restoration in arid semiarid regions. Methodology/Principal Findings To distinguish the changes affected by biological crusts, we compared properties across three types successional (algae, lichens, mosses crust), as well referenced sandland Mu Us Desert, Northern China. Relationships between fractal...

Abstract Root‐associated fungi (RAF) are an important factor affecting the host's growth, and their contribution to Pinus sylvestris var. mongolica plantation decline is substantial. Therefore, we selected three age groups of P. plantations (26, 33, 43 years), in Mu Us Desert, characterize community structure functional RAF, identified by Illumina high‐throughput sequencing FUNGuild platform, respectively. The effects soil properties enzyme activities on fungal diversity were also examined....

Plant temperature is an indicator of stomatal conductance, which reflects soil moisture stresses. We explored the relationship between plant and to optimize irrigation schedules in a water-stress experiment using Firmiana platanifolia (L. f.) Marsili incubator. Canopy temperature, leaf conductance were measured thermal imaging porometer. The results indicated that (1) decreased with declines moisture, reflected average canopy temperature; (2) variation distribution was reliable stress,...

We explored the process of urbanization in a mountainous area to seek sustainable strategy. Previous research has mainly focused on flat terrain and coastal areas, areas remains poorly understood. This study integrated geographic information systems, remote sensing, statistical analysis quantify landscape patterns dynamics response urbanization, with case Mentougou District Beijing, China from 1985 2014. found that total built-up increased along population economic indicators. The by...

Soil bacteria have been widely investigated and their roles in terrestrial ecosystems are relatively well understood. The soil bacterial community potential function controlled by vegetation factors indicating changes microenvironment. However, there is a knowledge gap regarding microbial influence use to predict the change metabolic after afforestation desert ecosystem. Pinus sylvestris var. mongolica most important evergreen species desertified northern China. Therefore, we used 16S rRNA...

Abstract This study assessed the influence of rhizocompartment types (i.e., root, rhizosphere soil, root‐zone and intershrub bulk soil) on diversity soil microbial communities under desert leguminous plant shrubs. Moreover, variations physicochemical factors in interactions among plants, microbes were investigated. Both 16S rRNA high‐throughput genome sequencing conventional index determination used to characterize both bacterial properties rhizocompartments two Hedysarum species (...

Revegetation is regarded as an effective means to improve the ecological environment in deserts and profoundly influences potential functions of soil fungal community. Therefore, Illumina high-throughput sequencing was performed characterize diversity community composition at two depths (0–10 cm 10–20 cm) with four revegetation durations (natural grassland, half-mature, nearly mature, mature Pinus. sylvestris var. mongolica plantations) Mu Us Sandy Land, China. The effects properties on...

Hedysarum scoparium is an important, fast-growing and drought-resistant shrub that has been extensively used for grassland restoration preventing desertification in semiarid regions of northwestern China. The primary objective this study was to investigate the diurnal seasonal variations stem sap flow (Js) its relation environmental factors. heat balance method applied plants were approximately 17 years old (with diameters 25, 16, 13, 9 mm at ground level heights 3.1, 1.8, 1.7 1.4 m) growing...

By assessing diversity variations of bacterial communities under different rhizocompartment types (i.e., roots, rhizosphere soil, root zone and inter-shrub bulk soil), we explore the structural difference in microenvironments desert leguminous plant shrubs. Results will enable influence niche differentiation roots soil on stability three shrubs to be examined. High-throughput 16S rRNA genome sequencing was used characterize differences microbes rhizocompartments xeric plants. from this study...

Structure-based forest management is a scientific and easy-to-operate method for sustainable management. We analyzed the stand spatial structure of Larix principis-rupprechtii plantation under five reserve densities. The results indicated that with decrease densities after thinning, average mingling degree uniform angle index had an increasing tendency, but amplitude was small. Most trees were in zero mix, few them moderate, strong, relatively strong mix; horizontal distribution patterns or...
