The earthworm, as a soil engineer, plays highly important roles in the soil ecosystem for shaping soil structure, promoting soil fertility, regulating microbial community composition and activities and decomposing soil pollutants. However, the research progresses on this important soil fauna have rarely been reviewed so far. Therefore, we conducted...

Response of growth rate and antioxidative system of ten Bacillus strains to acid stresses was assayed. Strong acid treatment significantly decreased the growth rate of the strains. Acid stresses increased the GPX activity and GSSG content of the tested strains. Divergent changes occurred in ROS and antioxidative system (SOD, CAT, GR, MDA and GSH)....

As a global pollution, acid rain can significantly alter soil physicochemical and biochemical processes, but our knowledge of how acid rain affects soil enzyme activity is still limited. To quantify the overall magnitude and direction of the response of soil enzyme activity to acid rain, we conducted a linear mixed model–based meta-analysis of 40 a...

BACKGROUND Fragrant rice is increasingly popular with the public owing to its fresh aroma, and 2‐acetyl‐1‐pyrroline (2‐AP) is the main characteristic component of the aroma in fragrant rice. Rice–fish co‐culture is an environmentally friendly practice in sustainable agriculture. However, the effect of rice–fish co‐culture on 2‐AP in grains has rece...

Acid rain threatens the function and structure of terrestrial ecosystems; however, the mechanisms by which acid rain affects the photosynthesized carbon (C) fluxes and soil microbial communities are far less understood, thus impeding accurate projections of regional C flux in plant-soil-atmosphere systems. In this study, we performed an isotopic 13...

Emerging microplastics (MPs) pollution and continuing acid rain (AR) co-exist in terrestrial ecosystems, and are considered as threats to ecosystems health. However, few data are available on MPs-AR interactions in plant-microbe-soil systems. Here, a microcosm experiment was manipulated to elucidate the co-exposure of polyethylene MPs (PE MPs; 1%,...

Antibiotic contamination in water has been an increasing global concern, and how to effectively remove antibiotics (e.g., oxytetracycline [OTC] hydrochloride) from wastewater becomes imperative. In this study, the biochar derived from an invasive plant (Mikania micrantha Kunth) was synthesized with Zn/Fe- layered double hydroxide (LDH) by co-precip...

Soil acidification is a global environmental issue that decreases soil functions, and it has been significantly accelerated by anthropogenic activities in recent decades. Soils can resist acidification upon receiving acid inputs due to the resistance or/and resilience capacity of soils, which is termed the acid buffering capacity of soils, and it i...

The increasing microplastics (MPs) pollution and continuous acid rain coincide in many areas of the world. However, if and how MPs interact with acid rain are still unclear. Herein, we conducted a microcosm experiment to decipher the combined effect of polyethylene (PE) MPs (1%, 5%, and 10%) and acid rain (pH 4.0) on the agricultural soil ecosystem...

Soil microbial community drives the terrestrial carbon (C) cycling by C sources metabolism (i.e., organic C decomposition), however, the microbial response to changing acid rain frequency remains less studied, thus hampering global warming projection. Here, we manipulated a simulated experiment to decipher the impact of acid rain frequency (0, 30%,...

Contamination of microplastics (MPs) is a global environmental issue that has received much attention from the scientific and public communities due to ecological concerns in recent decades. Comparing with aquatic ecosystems, soil systems, regardless of the high importance and complexity, have been less studied under widely existing and increasing...

Acid rain, as one of the global environmental issues, alters the biogeochemistry of terrestrial ecosystems. However, the responses of soil greenhouse gases (GHGs) emissions to acid rain remain unclear, thus creating large uncertainties in the prediction of global climate change. Here, we conducted a meta-analysis based on existing 42 studies to ass...

Acid rain alters soil carbon (C) cycling by influencing the soil microbial community structure and functions. However, the response of soil microbial communities to acid rain with time and underlying mechanisms are still poorly understood. Herein, we conducted a one-year intact soil core experiment to investigate the temporal changes of soil microb...

Acid rain (AR), as a global environmental threat, has profoundly adverse effects on natural soil ecosystems. Microorganisms involved in the nitrogen (N) cycle regulate the global N balance and climate stabilization, but little is known whether and how AR influences the structure and complexity of these microbial communities. Herein, we conducted an...

The level of acidity in rainfall can alter soil nutrient cycling (e.g., carbon [C] cycle), while the effect of changing acid rain frequency on soil C cycling and involved microbial communities remains largely understudied. Here, we manipulated a laboratory intact soil core experiment to test the effect of acid rain frequency (0, 30% and 100%) on so...

Litter decomposition is of utmost importance to elemental cycling in terrestrial ecosystems, with litter quality being frequently considered to predominantly control litter decomposition. However, how acid rain (AR) would affect litter decomposition and its elements release remains inconclusive, although AR has widely occurred in Europe, North Amer...

Acid rain has been one of the major environmental problems in industrial countries. While it may affect the litter decomposition, a highly important microbial-driven biogeochemical process, knowledge about the impact of acid rain on litter-decomposing microbial communities and their functions remains unclear. Therefore, this experiment was conducte...

With the continuation of industrialization and urbanization, acid rain (AR) has aroused extensive concern because of its potential negative effects on ecosystems. However, analysis of the current status and development trends in AR research area has seldom been systematically studied. Therefore, we motivated to conduct a bibliometric analysis of AR...

Objective: To investigate responses of litterfall carbon (C) and nitrogen (N) fractions to atmospheric N deposition in a monsoon evergreen broad-leaved forest. Method: Three levels of N addition, including low N (LN, 35 kg•hm⁻²), medium N (MN, 70 kg•hm⁻²) and high N (HN, 105 kg•hm⁻²), were conducted for two years, with a control without extra N add...

Cadmium (Cd) is one of the mostly hazardous soil pollutants and has threatened human health by accumulating in grains of crops. Phytoremediation is a promising technique to remedy soil Cd contamination, but reported Cd hyperaccumulators remain limited. In this study, we explored potential applicability of three invasive plant species (Chromolaena o...
