Soil Microbial Communities Changes Along Depth and Contrasting Facing Slopes at the Parque Nacional La Campana, Chile

Microorganisms
The Parque Nacional La Campana (PNLC) was recently recognized for its high soil surface microbial richness. Here, we explored the microbial community structure in soil profiles from contrasting facing slopes where sclerophyllous forest (SF) and ...

Temperate Forest Floors: Ecosystem Hubs in Transition?

Global Change Biology, Volume 32, Issue 8, August 2026.
The forest floor (FF) is a key component of carbon, nutrient, and water cycling and represents the most biologically active part of forest soils. Despite its importance, its response to environmental change and forest management remains insufficiently studied.

Three Decades of Soil N2O Research—Insights and Gaps

Global Change Biology, Volume 32, Issue 8, August 2026.
Progress in N2O Research and Key Breakthroughs and Transitions from 1990 to 2025 across three domains: (A) process understanding, (B) microbial ecology, and (C) modelling of soil N2O emissions. ABSTRACT Nitrous oxide (N2O) is a potent greenhouse gas (GHG) whose atmospheric concentration continues to rise, largely driven by nitrogen (N) inputs to ...

Substrate‐driven enrichment and eDNA metabarcoding reveal indigenous microbiomes in mangrove sediments with potential for ammonia and nitrite transformation

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Effective management of ammonia and nitrite remains a major challenge in intensive shrimp aquaculture, where excessive nitrogen loading compromises water quality and animal health. Indigenous microbial communities inhabiting mangrove sediments are widely considered potential sources of ammonia‐ and nitrite‐transforming microorganisms; however,

Subsurface Production of Marine Derived Bacterial Tetraether Lipids: Implications for Paleoceanographic Reconstruction

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are widely used as paleoclimate proxies on land, yet their origin in marine environments remains incompletely constrained. Here, we analyze suspended particulate matter collected from five depths at an open‐ocean station in the northern South China Sea and provide depth‐resolved evidence

Hydroxylamine released by nitrifying microorganisms is a precursor for HONO emission from drying soils

Scientific Reports, 2018
Nitrous acid (HONO) is an important precursor of the hydroxyl radical (OH), the atmosphere´s primary oxidant. An unknown strong daytime source of HONO is required to explain measurements in ambient air.

Vertical segregation and phylogenetic characterization of ammonia-oxidizing bacteria and archaea in the sediment of a freshwater aquaculture pond

Frontiers in Microbiology, 2016
Pond aquaculture is the major freshwater aquaculture method in China. Ammonia-oxidizing communities inhabiting pond sediments play an important role in controlling culture water quality.

Benthic Ammonia Oxidizers Differ in Community Structure and Biogeochemical Potential Across a Riverine Delta

Frontiers in Microbiology, 2015
Nitrogen pollution in coastal zones is a widespread issue, particularly in ecosystems with urban or agricultural watersheds. California’s Sacramento-San Joaquin Delta, at the landward reaches of San Francisco Bay, is highly impacted by both agricultural ...

Communities of ammonia-oxidizing bacteria, ammonia-oxidizing archaea and nitrite-oxidizing bacteria in shrimp ponds

Annals of Microbiology, 2014
The communities of nitrifying microorganisms were identified in samples taken from six shrimp ponds in Thailand (five outdoor-earthen ponds and one indoor pond). The sequences of ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA), and nitrite-oxidizing bacteria (NOB) were analyzed after specific PCR amplification of the 16S rRNA or amoA ...
