• Networks are used to study the relationships within microbial communities. • Construction methods and experimental design influence conclusions. • Applying network analysis to soil microbial datasets holds specific challenges. • Soil heterogeneity and the nature of soil sequencing data has to be considered. • Network analysis can offer novel insi...
BACKGROUND: Peatlands are expected to experience sustained yet fluctuating higher temperatures due to climate change, leading to increased microbial activity and greenhouse gas emissions. Despite mounting evidence for viral contributions to these processes in peatlands underlain with permafrost, little is known about viruses in other peatlands. Mor...

Invasive plants often impact soil conditions, notably through changes in soil chemistry and microbial community composition, potentially leading to altered soil functionality. We determine the impacts of invasive nitrogen-fixing Australian Acacia trees on soil chemistry and function (carbon, nitrogen, and phosphorus cycling) in South Africa's Core ...

The rice-crayfish co-cropping pattern is a traditional method for the intensive utilization of rice fields. In recent years, this pattern has been over-developed in many countries and regions, especially in China, because of its simple agronomic technology and high economic benefits. However, little is known about the potential ecological problems ...

The long-term effects on soil microorganisms from 40 years of irrigating soil with reclaimed wastewater was investigated by determining the quantity, composition, and inter-species connection of microorganisms. No significant difference in microbial quantity and composition were identified in the reclaimed wastewater- and groundwater-irrigated soil...
Polycyclic aromatic hydrocarbons (PAHs) are a class of compounds of environmental and public health concern because of their toxicity and environmental ubiquity that will be further exacerbated by increasing anthropogenic pollution. In situ bioremediation is a common cleanup technique for PAH-contaminated soils because it is considered to be cost-e...

Warming may increase the extent and intensity of insect defoliations within Arctic ecosystems. A thorough understanding of the implications of this for litter decomposition is essential to make predictions of soil-atmosphere carbon (C) feedbacks. Soil nitrogen (N) and C cycles naturally are interlinked, but we lack a detailed understanding of how i...
There is increasing evidence that the soil microbial community produces a suite of volatile organic compounds that suppress plant pathogens. However, it remains unknown which soil properties and management practices influence volatile-mediated pathogen suppression. The aim of this study was to relate soil properties to growth suppression of three p...
