Coupling Relationship Between Soil Properties and Plant Diversity Under Different Ecological Restoration Patterns in the Abandoned Coal Mine Area of Southern China.

Understanding the effects of ecological restoration in abandoned coal mines on soil and plant is important to improve the knowledge of ecosystems evolution and facilitate taking appropriate ecological restoration management practices. This study aims to evaluate the coupling relationship between plant diversity and soil properties after ecological restoration in abandoned coal mine area. The plant diversity such as Margalef index (), Simpson index (), Shannon-Wiener index (), and Pielou index (), and soil properties such as soil pH, soil water content (SWC), soil bulk density (SBD), soil organic matter (SOM), available nitrogen (AN), and microbial biomass carbon (MBC) were investigated in four sites of different ecological restoration patterns, T and study the coupling relationship between them.

Combined application of microbial inoculant and kelp-soaking wastewater promotes wheat seedlings growth and improves structural diversity of rhizosphere microbial community.

Industrial processing of kelp generates large amounts of kelp-soaking wastewater (KSW), which contains a large amount of nutrient-containing substances. The plant growth-promoting effect might be further improved by combined application of growth-promoting bacteria and the nutrient-containing KSW. Here, a greenhouse experiment was conducted to determine the effect of the mixture of KSW and Bacillus methylotrophicus M4-1 (MS) vs.

Isolation and identification of antagonistic HSE-12 and its effects on peanut growth and rhizosphere microbial community.

The HSE-12 strain isolated from peanut rhizosphere soil was identified as by observation of phenotypic characteristics, physiological and biochemical tests, 16S rDNA and gyrB gene sequencing. experiments showed that the strain possessed biocontrol activity against a variety of pathogens including . The strain has the ability to produce hydrolytic enzymes, as well as volatile organic compounds with antagonistic and probiotic effects such as ethyleneglycol and 2,3-butanediol.

HG-15, a Halotolerant Rhizoplane Bacterium, Promotes Growth and Salinity Tolerance in Wheat ().

Certain plant growth-promoting bacteria (PGPB) reduce salt stress damage in plants. HG-15 is a halotolerant bacterium (able to withstand NaCl concentrations as high as 30%) isolated from the wheat rhizoplane in the Yellow River delta. A qualitative and quantitative investigation of the plant growth-promoting characteristics of this strain confirmed nitrogen fixation, potassium dissolution, ammonia, plant hormone, ACC deaminase, and proline production abilities.

JF-22 to Control and Its Effect on Tomato Rhizosphere Microbial Community.

is one of the most destructive soil pests, causing serious economic losses in tomato production. Here, experiments demonstrated that the strain JF-22 has the potential to prevent infection. A pot experiment confirmed that strain JF-22 isolated from the tomato rhizosphere soil and planted in the tomato root-knot nematode disease area effectively prevented and controlled , reducing its negative effect on tomato growth.

Impacts of continuous and rotational cropping practices on soil chemical properties and microbial communities during peanut cultivation.

Long-term monocultures have severely inhibited the cultivation of Chinese peanut (Arachis hypogaea L.). In this study, the effects of continuous cropping on soil chemical properties and microbial communities were investigated in peanut fields that had been in crop rotation for 10 years and in monoculture for 10 years.

Impact of COVID-19 travel-restriction policies on road traffic accident patterns with emphasis on cyclists: A case study of New York City.

Since the COVID-19 outbreak, travel-restriction policies widely adopted by cities across the world played a profound role in reshaping urban travel patterns. At the same time, there has been an increase in both cycling trips and traffic accidents involving cyclists. This paper aims to provide new insights and policy guidance regarding the effect of COVID-19 related travel-restriction policies on the road traffic accident patterns, with an emphasis on cyclists' safety.

Effect of JC-K3 on Endophytic Bacterial and Fungal Diversity in Wheat Under Salt Stress.

Plant growth-promoting bacteria (PGPB) can effectively reduce salt damage in plants. Currently, there are many studies on the effects of PGPB on the microbial community structure of rhizosphere soil under salt stress, but fewer studies on the community structure of endophytic bacteria and fungi. We propose that inoculation of endophytic bacteria into the rhizosphere of plants can significantly affect the microbial community structure of the plant's above-ground and underground parts, which may be the cause of the plant's "Induced Systemic Tolerance.

The Effect of Salt-Tolerant Antagonistic Bacteria CZ-6 on the Rhizosphere Microbial Community of Winter Jujube ( Mill. "Dongzao") in Saline-Alkali Land.

As the main economic crop cultivated in the Yellow River Delta, winter jujube contains various nutrients. However, soil salinization and fungal diseases have affected the yield and quality of winter jujube. In order to use plant growth-promoting rhizobacteria (PGPR) to reduce these damages, the antagonistic bacteria CZ-6 isolated from the rhizosphere of wheat in saline soil was selected for experiment.

Cloud Formation From a Localized Water Release in the Upper Mesosphere: Indication of Rapid Cooling.

Polar mesospheric clouds (PMCs) occur in the summer near 82 -85km altitude due to seasonal changes of temperature and humidity. However, water vapor and associated PMCs have also been observed associated with rocket exhaust. The effects of this rocket exhaust on the temperature of the upper mesosphere are not well understood.

Observations of Reduced Turbulence and Wave Activity in the Arctic Middle Atmosphere Following the January 2015 Sudden Stratospheric Warming.

Measurements of turbulence and waves were made as part of the Mesosphere-Lower Thermosphere Turbulence Experiment (MTeX) on the night of 25-26 January 2015 at Poker Flat Research Range, Chatanika, Alaska (65°N, 147°W). Rocket-borne ionization gauge measurements revealed turbulence in the 70- to 88-km altitude region with energy dissipation rates between 0.1 and 24 mW/kg with an average value of 2.

[Study on the role of autophagy in heme oxygenase 1 preventing hepatic ischemia/reperfusion injury in rats].

Objective: To identify the role of autopahgy in the protective mechanism of heme oxygenase 1 (HO-1) against hepatic ischemia/reperfusion (I/R) injury.

Methods: Forty healthy male Sprague-Dawley (SD) rats were randomly (random number table) divided into five groups (n = 8 in each group), namely sham group, model group, cobalt protoporphyrin (CoPP) group, zinc protoporphyrin (ZnPP) group and 6-amino-3-methylpurine (3-MA) group. Partial hepatic I/R model was established by clamping the pedicles of left and median lobes for 1 hour and reopening for 6 hours in rats, and the rats in sham group were only received celiotomp without hepatic I/R.
