Soil moisture is connected to atmospheric through direct evaporation and vegetation transpiration. This a complex process that in focus of numerous hydrological studies. We used the long-term measurements from typical farming-pastoral ecotone northern Hebei Province China study relationship between daytime nighttime fluctuations grassland surface soil evapotranspiration. The results show above 60 cm main water consumption area, while below storage area. 80–100 layer responds precipitation...

Changes in forest cover can affect not only the total runoff from a watershed, but also components (e.g., surface runoff, interflow, groundwater flow). In this study, based on WetSpa model simulation method and recursive digital filtering (RDF) method, Banchengzi watershed mountainous region of Beijing, China, was selected to investigate how changes type percentage flow through scenario settings. Our results show that difference between RDF for separating is small, with 4.7% 0.4% calibration...

Thermoplasmatota have been widely reported in a variety of ecosystems, but their distribution and ecological role marine sediments are still elusive. Here, we obtained four draft genomes affiliated with the former RBG-16-68-12 clade, which is now considered new order, "Candidatus Yaplasmales," phylum from South China Sea. The phylogenetic trees based on 16S rRNA genes showed that "Ca. Yaplasmales" archaea composed three clades: A, B, C. Among them, clades A B abundantly distributed (up to...

Abstract Background Accurate estimation of potential evapotranspiration (PET) is the key for studying land-air interaction hydrological processes. Several models are used to estimate PET based on standardized meteorological data. Although combination-based have highest level performance PET, they require more data and may therefore be difficult apply in areas lacking observation Results The results showed significant differences spatial trends calculated by different China,...

A significant but challenging task is the development of a rechargeable Zn–air battery bifunctional catalyst. Here, supramolecular self-assembly poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol) (P123) was designed to construct Co2P nanoparticles encapsulated in N-doped carbon nanotubes (Co2P@NCNT-x). The results show that P123 an important factor formation coated with nanoparticles. Co2P@NCNT-4 catalyst exhibits maximum limiting diffusion current density (5.2...

The aim of the present study was to investigate application 3D printing (3DP) rapid prototyping (RP) technique‑assisted percutaneous fixation in treatment femoral intertrochanteric fracture (ITF) using proximal nail anti‑rotation (PFNA). A total 39 patients with unstable ITF were included current study. Patients divided into two groups: 19 examined computed tomography scanning and underwent PFNA SDP‑RP whereas other 20 conventional treatment. Anatomical data converted from Digital Imaging...

Global climate change, characterized by changes in precipitation, prolonged growing seasons, and warming-induced water deficits, is putting increased pressure on forest ecosystems globally. Understanding the impact of change drought-prone forests a key objective assessing responses to change. In this study, we assessed tree growth trends physiological activity under based measurements ring stable isotopes. Additionally, structural equation models were used identify drivers influencing for...

The deep-sea hydrothermal vents (DSHVs) in the Southwest Indian Ridge (SWIR) are formed by specific geological settings. However, community structure and ecological function of microbial inhabitants on sulfide chimneys active remain largely unknown. In this study, our analyses 16S rRNA gene amplicons metagenomic reads showed dominance sulfur-oxidizing Ectothiorhodospiraceae, Thiomicrorhabdus , Sulfurimonas Sulfurovum wall two chimneys. Compared with inactive sediments SWIR, lacked...

It is desirable to prepare low-cost non-noble metal catalysts using a simple and efficient method. Herein, we display for the first time that nitrogen-doped hierarchical porous carbon-supported vanadium nitride (VN/NC/C-x) can be regulated by dicyandiamide (DCDA). The introduction of DCDA not only effectively controls pore structure, but also plays an important role in adjusting oxygen vacancies d-electrons. In addition, significant raw material N-doped carbon, nitrogen source preparation...

Marine Synechococcus are an ecologically important picocyanobacterial group widely distributed in various oceanic environments. Little is known about the dynamics and distribution of abundance genotypes during seasonal hypoxia coastal zones. In this study, investigation was conducted a marine ranch along two transects Muping, Yantai, where hypoxic events (defined here as dissolved oxygen concentration &lt;3 mg L−1) occurred summer 2015. The bottom waters from late July persisted until...

Candidate phylum KSB1 is composed of uncultured bacteria and has been reported across various environments. However, the phylogeny metabolic potential have not studied comprehensively. In this study, phylogenomic analysis genomes from public databases eleven metagenome-assembled (MAGs) marine hydrothermal sediments revealed that those were clustered into four clades. Isolation source relative abundance showed clade I was particularly abundant in bioreactor sludge. Genes related to...
