Seasonal Variations in Aerosol Trace Element Source Contributions and Deposition Fluxes to the North Pacific Subtropical Gyre

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Trace elements deposited in the marine environment affect ocean biogeochemistry in numerous, complex ways. This study quantifies seasonal aerosol trace element (TE) fluxes and evaluates their variability and potential sources over a 2‐year period in the North Pacific subtropical gyre (NPSG). We established the Hawaii Aerosol Time Series (HATS),

Diazotrophic abundance and community structure associated with three meadow plants on the Qinghai-Tibet Plateau

Frontiers in Microbiology
Symbiotic diazotrophs form associations with legumes and substantially fix nitrogen into soils. However, grasslands on the Qinghai-Tibet Plateau are dominated by non-legume plants, such as Kobresia tibetica.

Cross-Bioaugmentation Among Four Remote Soil Samples Contaminated With Oil Exerted Just Inconsistent Effects on Oil-Bioremediation

Frontiers in Microbiology, 2019
Soil samples were collected from Kuwait, Lebanon, Egypt, and Germany, and artificially polluted with 3% (w/w) crude oil. Cross-bioaugmentation was done among them, and the oil-consumption and the constituent communities of hydrocarbonoclastic bacteria ...

Amazon River Plume Control on Carbonate Chemistry in the Western Tropical Atlantic

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract The Amazon River Plume (ARP) modulates the carbonate system of the western Tropical Atlantic (WTA) through physical and biological processes, including freshwater dilution, biological carbon uptake, and circulation‐driven transport; however, its basin‐scale impact has not been quantitatively assessed.

Long-Term Warming in Alaska Enlarges the Diazotrophic Community in Deep Soils

mBio, 2019
Tundra ecosystems are typically carbon (C) rich but nitrogen (N) limited. Since biological N2 fixation is the major source of biologically available N, the soil N2-fixing (i.e., diazotrophic) community serves as an essential N supplier to the tundra ...

Dissolved Organic Matter Impacts Nitrogen Fixation in the Arctic Ocean

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Climate change‐driven sea ice loss, increased primary production, and nitrogen depletion are reshaping biogeochemistry in the Arctic Ocean (AO). These changes potentially increase the importance of nitrogen fixation, the conversion of dinitrogen gas into bioavailable ammonium, carried out by microorganisms called diazotrophs.

The Chaetocerosphere: Chaetoceros Species and Associated Prokaryotes in a Coastal Area

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Chaetoceros species maintain recurrent distinct prokaryotic assemblages in their phycosphere. Alphaproteobacteria, Bacteroidetes and Archaea Thermoplasmata and Marine Group II are the most represented in the phycosphere. Bipartite networks highlight strong links between the diatom and specific prokaryotic taxa, especially the chain‐forming species ...

Multispecies Pasture Reshapes Subsoil Bacterial and Fungal Communities Compared to Ryegrass Monoculture

Grass and Forage Science, Volume 81, Issue 4, October/December 2026.
ABSTRACT Perennial ryegrass (Lolium perenne L.) underpins the pasture‐based dairy industry in Australia, yet its shallow root system limits adaptation to drought conditions. Multispecies pastures, consisting of grasses, legumes and herbs, are increasingly adopted to improve ecosystem resilience, but their interactions with soil microorganisms ...

Ca. Nitrososphaera and Bradyrhizobium are inversely correlated and related to agricultural practices in long-term field experiments

Frontiers in Microbiology, 2013
Agricultural land management, such as fertilization, liming, and tillage affects soil properties, including pH, organic matter content, nitrification rates, and the microbial community.

Microbiome‐mediated plant‐soil feedbacks as a tool for resilient agriculture

iMetaOmics, Volume 3, Issue 3, September 2026.
Translating plant‐soil feedbacks (PSFs) into reliable agricultural management requires shifting from input‐dependent practices toward endogenous, process‐driven crop resilience. To bridge this gap, we propose a predictive framework centered on three strategic interventions: engineering the crop holobiont, diversifying the soil habitat, and deploying ...
