Spatial and Temporal Variability of Microbial Nitrogen Cycling Genes in Arctic Streams

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The Arctic is undergoing rapid climate change, with thawing permafrost and shifts in vegetation altering nitrogen (N) delivery into streams. These changes can significantly affect microbial biofilm diversity and functional roles, yet knowledge of streambed microbial biofilms remains scarce across the Arctic.

Plant Identity Impacts the Soil Microbiome More Than Interspecific Interactions in Intensively Managed Grasslands

European Journal of Soil Science, Volume 77, Issue 1, January–February 2026.
The impact of plant identity and interspecific interactions on the soil microbiome in intensively managaged grasslands. ABSTRACT Plants and soil microbes are intricately linked, and agricultural production relies heavily on microbially mediated ecosystem services. However, the effects of plant diversity (richness, relative abundance and composition) on

Growth of comammox Nitrospira is inhibited by nitrification inhibitors in agricultural soils [PDF]

Journal of Soils and Sediments, 2019
Purpose: The discovery of comammox Nitrospira being capable of complete oxidising ammonia to nitrate radically challenged the conventional concept of two-step nitrification. However, the response of comammox Nitrospira to nitrification inhibitors (NIs) and their role in soil nitrification remain largely unknown, which has hindered our ability to ...

Soil pH modulates microbial nitrogen allocation in soil via compositional and metabolic shifts across forests in Japan

iMetaOmics, Volume 2, Issue 4, December 2025.
This study reveals how soil pH regulates microbial N allocation in forest soils across Japan. We show that microbial abundance controls the overall rate of N cycling, while microbial composition and metabolic potential determine whether ammonium is released or retained.

Comprehensive evaluation of primer pairs targeting the ammonia monooxygenase subunit A gene of complete ammonia-oxidizing Nitrospira

Microbiology Spectrum
Since the discovery of complete ammonia oxidizers (comammox) within the genus Nitrospira, their distribution and abundance across habitats have been intensively studied to better understand their ecological significance.

Evaluating Performance of Bouteloua gracilis Cultivars After Drought: The Role of the Soil Microbiome

Grass and Forage Science, Volume 80, Issue 4, December 2025.
ABSTRACT After the Dust Bowl in the 1930s, it was common to reseed native grasses in areas impacted by the drought to help restore grassland ecosystem structure and function. Given the forecasts of intensified drought events, reseeding may need to be employed more frequently to enhance post‐drought recovery. For such reseeding efforts, it is imperative

Heterotrophic ammonia oxidation by Alcaligenes balances ROS generation and terminal electron transport

mLife, Volume 4, Issue 5, Page 527-538, October 2025.
Abstract Heterotrophic nitrifiers are bacteria that aerobically oxidize ammonia in the presence of organic carbon sources, which differs from autotrophic nitrifiers that extract energy from ammonia oxidation for cell metabolism and growth. The physiological significance of heterotrophic ammonia oxidation remains unclear, even though this process has ...

DNA- and RNA-SIP Reveal Nitrospira spp. as Key Drivers of Nitrification in Groundwater-Fed Biofilters

mBio, 2019
Nitrification, the oxidative process converting ammonia to nitrite and nitrate, is driven by microbes and plays a central role in the global nitrogen cycle.

Substrate Effect on the Contribution of Ammonium and Urea to Marine Nitrification and Nitrous Oxide Production

Environmental Microbiology, Volume 27, Issue 10, October 2025.
The urea to ammonium concentration ratio is a good predictor of the relative importance of urea and ammonium to nitrite and N2O production in the ocean. In addition, the urea to ammonium ratio may be a key factor in shaping the genetic capability of marine ammonia‐oxidising archaea for urea utilisation.

Subsoiling Combined With Winter Active Italian Ryegrass Can Reduce Nitrous Oxide Emissions Without Increasing Nitrate Leaching: Evidence From Lysimeter and Field Plot Trials

Soil Use and Management, Volume 41, Issue 4, October‐December 2025.
ABSTRACT Subsoiling is a common practice for improving soil structure and has recently been recognised for its potential to reduce nitrous oxide (N2O) emissions. However, its impact on nitrate (NO3−–N) leaching must also be considered if it is to be used as a mitigation strategy. This study investigated N2O emissions, NO3−–N leaching and grass yield in
