Environmental DNA, Volume 8, Issue 2, March/April 2026.This study uncovers key multifunctional genes in the rhizosphere of Allium ampeloprasum under varying fertilization systems. This highlights their roles in nutrient cycling, plant growth promotion, and soil health, thereby offering insight for sustainable agricultural sustainability.

Ribosomal RNA operon copy number: A trait‐informed framework to close the microbial cultivation gap
iMetaOmics, Volume 3, Issue 1, March 2026.The vast majority of microbes remain uncultured, constraining functional validation and limiting microbiome‐based applications. We show that ribosomal RNA operon (rrn) copy number—a stable, phylogenetically conserved genomic trait—is strongly correlated with cultivation outcomes across ecosystems.

Annual Variability in Marine Particulate Trace Elements During the Hawaii Aerosol Time‐Series
Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.Abstract The Hawaii Aerosol Time‐Series (HATS) was a coordinated effort to simultaneously monitor atmospheric and water column dust dynamics in the North Pacific Subtropical Gyre. Throughout 2022 and 2023, HATS measured the composition of water column particles and made complementary measurements of aerosol chemistry and deposition fluxes.

Frontiers in Microbiology, 2016 The human environment is predominantly not aqueous, and microbes are ubiquitous at the surface-air interfaces with which we interact. Yet microbial studies at surface-air interfaces are largely survival-oriented, whilst microbial metabolism has ...

In-depth characterization of diazotroph activity across the western tropical South Pacific hotspot of N2 fixation (OUTPACE cruise) [PDF]
Biogeosciences, 2018 Here we report N2 fixation rates from a ∼ 4000 km transect in the western and central tropical South Pacific, a particularly undersampled region in the world ocean.

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.Abstract With ca. 700 Pg C, dissolved organic carbon (DOC) represents the largest organic carbon reservoir in the ocean, serving both as a carbon storage and the base for the heterotrophic microbial food web. Despite its significance in the marine ecosystem, the mechanisms driving its spatial variability remain poorly understood.

High sensitivity of ultra-oligotrophic marine ecosystems to atmospheric nitrogen deposition [PDF]
, 2012 Using a model of plankton and organic-matter cycling we demonstrate that variable stoichiometric ratios can lead to a more than 5-fold higher sensitivity of simulated carbon export to atmospheric N deposition in the ultra-oligotrophic eastern part of the

Oligotrophy and pelagic marine bacteria
Aquatic Microbial Ecology, 1997 Oligotrophy, or the inability of bacterial cells to propagate at elevated nutrient concentrations, is a controversial phenomenon in microbiology. The exact cause of the unculturability of many indigenous marine bacteria on standard laboratory media has still not been resolved.

The UW National Parks Service Research Station Annual Reports, 1983 Our research attempts to characterize the recent historical events in Yellowstone Lake, especially with regard to the hypothesis that the lake has become more oligotrophic.
