A framework to bridge scales in distribution modeling of soil microbiota
This paper introduces a nested framework to bridge the gap between local drivers of soil microbial distributions and the global scale at which most spatial environmental data are available.

Regional and oyster microenvironmental scale heterogeneity in the Pacific oyster bacterial community
This study is a comprehensive analysis of four C. gigas tissue bacterial communities across six discrete estuaries spanning 470 km with an emphasis on identifying ‛core’ elements of the oyster bacterial community.
Genome reconstruction reveals distinct assemblages of Gallionellaceae in surface and subsurface redox transition zones
Genome reconstruction of Gallionellaceae dwelling in groundwater of a fractured aquifer suggests niche partitioning linked to the physical nature of the oxic-anoxic interface developing belowground and at the surface.
Straw decreased N2O emissions from flooded paddy soils via altering denitrifying bacterial community compositions and soil organic carbon fractions
This study revealed straw return suppressed N2O emission via altering denitrifying bacterial community compositions and highlighted the importance of EOC in controlling denitrifying bacterial communities.
Soil microbial diversity in adjacent forest systems – contrasting native, old growth kauri (Agathis australis) forest with exotic pine (Pinus radiata) plantation forest
Shifts in soil microbial communities surrounding fragmented kauri forests due to pine plantation establishment may impact forest health already under threat from the spread of an invasive pathogen.
Comparative analysis of the total and active bacterial communities in the surface sediment of Lake Taihu
From the quantitative and qualitative results, we demonstrated that the analysis of the sediment bacterial communities at the RNA level was more informative than that at the DNA level.
Endophytic microbial assemblage in grapevine
This study investigates the origin and assembly of the microbial endophytes inhabiting grapevine, and highlights bacteria and fungi that may play a role in the host environmental fitness.
Metagenome-assembled genome distribution and key functionality highlight importance of aerobic metabolism in Svalbard permafrost
Two novel computational methods were developed to conduct a deep metagenomic analysis of Svalbard permafrost samples, resulting in previously unreported trends in permafrost, especially the importance of aerobic metabolisms.
Insights into the community structure and lifestyle of the fungal root endophytes of tomato by combining amplicon sequencing and isolation approaches with phytohormone profiling
This article provides novel insights into the role of plant hormones and host genotype in the structure of the fungal communities inhabiting tomato roots, while also exploring the fungal lifestyle.
Aggregate size-dependence of bacterial community separation in a full-scale membrane bioreactor plant
Co-occurrence of rhizobacteria with nitrogen fixation and/or 1-aminocyclopropane-1-carboxylate deamination abilities in the maize rhizosphere
The co-selection of different microbial functional groups reinforces the hypothesis that functions are more important than the taxonomic composition of the microbiota.
Intestinal Enterococcus abundance correlates inversely with excessive weight gain and increased plasma leptin in breastfed infants
The reported findings suggest that lack of seeding with Enterococci from breastmilk into the infant gut influences the unusual development of excessive weight gain in breastfed infants.
Long-term effects of stump removal and tree species composition on the diversity and structure of soil fungal communities
Stump removal leads to an increase in ectomycorrhizal fungal associations, thus stumping can be considered a good management practice for mitigating root disease and promoting tree regeneration.
Abiotic factors influence patterns of bacterial diversity and community composition in the Dry Valleys of Antarctica
A landscape scale study of microbial community composition and structure in a biologically simple, microbially dominated cold desert system.
Structure and distribution of nitrite-dependent anaerobic methane oxidation bacteria vary with water tables in Zoige peatlands
Communities of nitrite-dependent anaerobic methane oxidizers vary with water table depth in Chinese peatlands.
Investigating bifidobacteria and human milk oligosaccharide composition of lactating mothers
In the current study, we quantified the abundance of members of the Bifidobacterium genus in 163 human milk samples using a combination of metagenomic and flow cytometry approaches.
Ecogenomics reveals community interactions in a long-term methanogenic bioreactor and a rapid switch to sulfate-reducing conditions
Metabolic reconstruction of core organisms in a methanogenic bioreactor and their responses to sulfate.
The roles of environmental variation and spatial distance in explaining diversity and biogeography of soil denitrifying communities in remote Tibetan wetlands
Both environmental filtering and spatial distance are important in explaining diversity and biogeography of soil denitrifying communities in remote and less disturbed wetlands.
Increased temperatures alter viable microbial biomass, ammonia oxidizing bacteria and extracellular enzymatic activities in Antarctic soils
Using an experimental manipulation, we show the effects of temperature increases on Antarctic soil ammonia oxidising bacteria.
Response of aquatic microbial communities and bioindicator modelling of hydraulic fracturing flowback and produced water
The first study to examine the effect of field-collected flowback and produced water, generated by hydraulic fracturing of shale gas wells, on the microbial ecology of freshwater systems.
