Background and AimsMany notorious alien invasive plants are clonal, but little is known about some roles aspects of clonal integration. Here, the hypothesis tested that integration affects growth, photosynthetic efficiency, biomass allocation competitive ability exotic weed Alternanthera philoxeroides (Amaranthaceae).

Land degradation and agricultural pollution have been of great concern around the world in recent years, especially developing countries. It is necessary to expand some eco-friendly soil-management practices address serious environmental issues. Using data from 646 small-farm households Shandong, China, perceptions land degradation, adoption attitudes final decisions are all evaluated, factors affecting farmers' estimated by applying a logit model. The results show that perception levels...

Cisplatin resistance remains a major clinical obstacle to the successful treatment of non-small cell lung cancer (NSCLC). Scribble contributes ROS-induced inflammation and cisplatin-elevated toxic reactive oxygen species (ROS) promotes death. However, it is unknown whether how involved in cisplatin-related death underlying mechanism response chemotherapies process oxidative stress NSCLC.We used two independent cohorts NSCLC samples derived from patients treated with platinum-containing...

In North Korea, reliable and timely information on crop acreage spatial distribution is hard to obtain. this study, we developed a fast robust method estimate in Korea using time-series normalized difference vegetation index (NDVI) derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) data. We proposed identify type based NDVI phenology features data collected other areas with similar agri-environmental conditions mitigate shortage of ground truth Eventually classification...

Food waste (FW) biodegradation by microbial augmentation is an emerging approach for FW treatment. In this study, agent composed of six dominant thermophilic aerobic bacteria identified as Geobacillus lituanicus, kaustophilus, thermoparaffinivorans, caldoxylosilyticus, Bacillus smithii and Acinetobacter pittii was used to enhance the degradation organic matter in during process. The results showed that volatile solid removal (VSR) 58.42% experimental group inoculated with agent, while it...

Abstract Regional warming and atmospheric ozone (O 3 ) pollution are two of the most important environmental issues, commonly coexist in many areas. Both factors have an intense impact on plants. However, little information is available combined interactive effects air elevated O concentrations physiological characteristics To explore this issue, we studied variations growth, photosynthesis leaves Acer ginnala seedlings exposed to control (ambient temperature ), increasing + 2 °C),...

According to the spatial structure characteristics of road curbs and surfaces, a robust method for automatic extraction boundaries, surfaces was proposed using mobile laser scanning (MLS) point cloud data. Firstly, ground filtering performed separate points non-ground according angle between normal vector direction z-axis. Secondly, based on vertical linear features curb, MLS trajectory were used extract curb boundary points. Then, Euclidean clustering fitting segments. Adjacent clusters...

Abstract Climate warming and management will likely affect carbon (C) fluxes of montane grassland ecosystems. In this study, we assessed the effect simultaneous (+2°C) decreased precipitation (−25%) on exchange grasslands in S‐Germany by translocating large intact plant‐soil cores from a high altitude to low site. Cores received two common regimes: intensive (4–5 cuts slurry application) extensive (1–2 application). Diurnal patterns net ecosystem (NEE) total respiration (Reco) were measured...

Recently, the increasing shrub-encroached grassland in Mongolian Plateau partly indicates quality decline and degradation. Accurate shrub identification regional difference analysis are significant for ecological degradation research. Object-oriented filter (OOF) digital surface model (DSM)-digital terrain (DTM) analyses were combined to establish a high-accuracy automatic algorithm (CODA), which made full use of remote sensing products by unmanned aircraft systems (UASs). The results show...

A novel bis(indolyl)methane-modified silica reinforced with multiwalled carbon nanotubes sorbent for solid-phase extraction was designed and synthesized by chemical immobilization of nitro-substituted 3,3'-bis(indolyl)methane on modified nanotubes. Coupled high-performance liquid chromatography analysis, the properties were evaluated flavonoids aromatic organic acid compounds. Under optimum conditions, can simultaneously extract five two preservatives in aqueous solutions a single-step...

In traditional industrialization, manufacturing industries are clustering with a large amount of carbon dioxide (CO2) emissions which has been polluting the environment heavily and directly caused global climate change. Industry CO2 reduction is key point for change mitigation. The authors in this paper introduce new concept industry efficiency relatively design an coefficient to measure it. With sample analysis Chongqing China, find that 11 18 sectors have their great potentials comparing...

This paper proposes an effective and practical method for self-calibration of traffic surveillance cameras. Based on analyzing multiple moving vehicles across frames, the Canny edge detector Hough transform are first adopted to obtain orthogonal horizontal vanishing points pairs, from which corresponding vertical derived. Next, mean shift clustering Laplace linear regression employed deal with noise outliers during estimation points. To overcome unreliable issues we further utilize...

This paper develops a China urban-rural input-output model and applies the price to evaluate impact of rise in energy on fluctuations agricultural products prices income expenses. The results show that rises may lead agiricultural by 26-47%. With price, net profit agriculture hurts those coastal provinces some central who have higher intensification, while benefits western regions with lower intensification. consumer surplus both urban rural residents is reduced rise. While influence greater...

Climate warming has significantly alerted the terrestrial carbon dynamics, resulting in enhanced vegetation productivity, especially northern hemisphere.However, most of prior modeling studies have neglected effects nutrient availability, such as phosphorus limitation, on processes, which potentially leads to an overestimation capacity ecosystems sequester additional carbon.Here, we reviewed recent progress limitation and its interactions with dynamics context climate change, a focus...

This study aimed to enhance the ultrasonic-assisted extraction (UAE) yield of seawater Arthrospira platensis polysaccharides (APPs) and investigate its structural characteristics bioactivities. The optimization UAE achieved a maximum crude 14.78%. optimal conditions were liquid–solid ratio 30.00 mL/g, temperature 81 °C, ultrasonic power at 92 W time 30 min. After purification through cellulose DEAE-52 Sephadex G-100 columns, two polysaccharide elutions (APP-1 APP-2) obtained. APP-2 had...

Phosphorus (P) is a fundamental component of plant organisms. Most the Earth System Models (ESMs) project increases in future Net Primary Productivity (NPP) due to climate warming. However, large uncertainty exists projected NPP P limitation. Subtropical China region with high vegetation NPP, but its forests are mostly limited. In this study, we used simulations Atmospheric-Vegetation Interaction Model 2 (AVIM2) diagnose limitation region, and found that warming period 1951–2010 had enhanced...
