Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress

open access: yesEcological Research, Volume 41, Issue 5, September 2026.
This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

Variation in soil nitrous oxide emission with nitrogen application rates under reclaimed water irrigation

open access: yesFrontiers in Environmental Science
Nitrous oxide (N2O) is a potent greenhouse gas primarily emitted from agricultural soils through microbial nitrogen transformation processes. Different nitrogen application rates and fertilizer types influence soil nitrogen transformation pathways ...

Can Organic Amendments Override Environmental Filtering of Soil Microbiomes? Evidence From 20 Years Old Agricultural Field Trials in Contrasting Tropical Sites

open access: yesGlobal Change Biology, Volume 32, Issue 9, September 2026.
Across four long‐term Kenyan maize trials, site was the dominant driver of microbial community composition and N‐cycling gene abundance. Among organic amendments, farmyard manure most strongly enriched copiotrophic taxa and raised prokaryotic diversity.

Abalone Gut Microbiome Regulators: A Review Synthesizing Gut Physiology, Microorganisms, Diet and the Environment

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Abalone are economically, ecologically and culturally significant marine molluscs, with both wild and farmed populations under pressure due to intrinsic and extrinsic stressors. Abalone performance and health are centred on a highly specialized digestive system supported by a diverse gut microbiome, which enables nutrient assimilation ...

Comparative Microbial Nitrogen Functional Gene Abundances in the Topsoil vs. Subsoil of Three Grassland Habitats in Northern China

open access: yesFrontiers in Plant Science, 2022
The microbial groups of nitrogen fixers, ammonia oxidizers, and denitrifiers play vital roles in driving the nitrogen cycle in grassland ecosystems. However, the understanding of the abundance and distribution of these functional microorganisms as well ...

Nutritional Composition of African Catfish (Clarias gariepinus) in Ghana: Effects of Culture Conditions, Feed and Processing

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
This review synthesizes current evidence on the nutritional composition of African catfish (Clarias gariepinus), with emphasis on Ghanaian aquaculture. The species is a valuable source of high‐quality protein, essential amino acids, minerals and vitamins, although lipid composition varies widely.

Association of the CCR5 gene with juvenile idiopathic arthritis [PDF]

open access: yes, 2010
The CC chemokine receptor 5 (CCR5) has been shown to be important in the recruitment of T-helper cells to the synovium, where they accumulate, drive the inflammatory process and the consequent synovitis and joint destruction.

Comparison of water availability effect on ammonia-oxidizing bacteria and archaea in microcosms of a Chilean semiarid soil

open access: yesFrontiers in Microbiology, 2012
Water availability is the main limiting factor in arid soils; however few studies have examined the effects of drying and rewetting on nitrifiers from these environments.

Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary

open access: yesEnvironmental Microbiology, Volume 28, Issue 8, August 2026.
Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...

Impacts of Cu and sulfadiazine on soil potential nitrification and diversity of ammonia-oxidizing archaea and bacteria

open access: yesEnvironmental Pollutants & Bioavailability, 2019
Soil potential nitrification rate (PNR) and diversity of ammonia-oxidizing microbes were investigated in spiked soils with Cu and Sulfadiazine (SDZ). An obvious decrease of PNR was observed with the increase of Cu and SDZ concentrations in the soil. Real-
