Marine Plug Flow Bioreactors Provide a High‐Throughput Assay of Potential DOC Bioavailability

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 11, November 2026.
Abstract Dissolved organic carbon (DOC) forms the largest reservoir of reduced carbon in the ocean, yet its bioavailability and the microbial processes governing its transformation remain poorly constrained. Traditional seawater batch cultures have been indispensable for measuring bioavailable DOC (BDOC), but their long incubation times and limited ...

Land use intensification results in abrupt transitions between extensively and intensively managed grasslands

open access: yesFunctional Ecology, Volume 40, Issue 11, Page 3577-3591, November 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding whether land use intensification causes regime shifts (i.e. persistent, large changes in ecosystem states) is of key importance for management, particularly if these shifts occur abruptly as thresholds in land use intensity are crossed.

Comparison of lipid biomarker and gene abundance characterizing the archaeal ammonia-oxidizing community in flooded soils

open access: yes, 2011
In the last years, archaea have been identified as key players in global N cycling, especially in nitrification. Ammonia-oxidizing archaea (AOA) are postulated to belong to the new phylum Thaumarchaeota for which the lipid crenarchaeol should be specific.

Biochar Mitigates N2O and NH3 Emissions for Organic and Inorganic Fertilizers in an Austrian Field Experiment

open access: yesEuropean Journal of Soil Science, Volume 77, Issue 6, November–December 2026.
ABSTRACT Biochar is a promising soil management strategy to reduce reactive nitrogen (Nr) losses from agricultural soils, and replacing mineral fertilizers with organic amendments (OAs) can improve soil health and enhance nutrient recycling. We conducted a three‐year field experiment with maize (Zea mays) in Lower Austria to compare organic waste ...

Impact Crater Hydrothermal Systems Support Rapid Microbial Enrichment and Diverse Metabolic Potential

open access: yesGeobiology, Volume 24, Issue 6, November/December 2026.
ABSTRACT Impact crater hydrothermal systems, formed after asteroid and comet impacts, have been proposed as promising habitats for life on early Earth and as key targets in the search for life on planetary bodies such as Mars, since they provide liquid water and active geochemical turnover.

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

open access: yesScientific 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.

Occurrence of ammonia-oxidizing archaea in wastewater treatment plant bioreactors

open access: yes, 2006
We report molecular evidence that ammonia-oxidizing archaea (AOA) occur in activated sludge bioreactors used to remove ammonia from wastewater. Using PCR primers targeting archaeal ammonia monooxygenase subunit A (amoA) genes, we retrieved and compared ...

Vinasse Processing Regulates N2O Emissions in Sugarcane Soils Through Water and Carbon Controls

open access: yesGCB Bioenergy, Volume 18, Issue 11, November 2026.
Alternative vinasse management strategies regulate N2O emissions in sugarcane soils through water and carbon controls. Processing vinasse can reduce N2O emissions while retaining its agronomic value. ABSTRACT Vinasse is a major residue of sugarcane‐based ethanol production and is widely applied to soils as an organic fertilizer.
