Biogeochemical Response to Mesoscale Eddies and Tehuano Wind Events in the Oxygen Minimum Zone off the Gulf of Tehuantepec

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract In the oxygen minimum zone of the eastern tropical North Pacific off the Gulf of Tehuantepec, mesoscale eddies and offshore jets often develop in response to Tehuano wind events. These dynamic features play crucial roles in modulating the vertical distribution of nutrients, dissolved oxygen, biogeochemical cycling, and regional primary ...

Correlation between anammox activity and microscale distribution of nitrite in a subtropical mangrove sediment [PDF]

, 2005
The distribution of anaerobic ammonium oxidation (anammox) in nature has been addressed by only a few environmental studies, and our understanding of how anammox bacteria compete for substrates in natural environments is therefore limited. In this study,

Development of a Mesoscale‐ and Tide‐Resolving Ocean–Biogeochemistry Model for the Pacific: Tidal Enhancement of the Biological Carbon Pump

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract This study presents a new physical‐biogeochemical simulation of the Pacific Ocean that resolves mesoscale dynamics and explicitly includes tidal forcing. The primary objective is to develop and document a modeling framework that serves both as a detailed record of model configuration and forcing preparation, and as a reference for future ...

Fate of dissolved organic nitrogen during the Anammox process using ultra-high resolution mass spectrometry

Environment International, 2019
Anaerobic ammonium oxidation (Anammox) is a cost-effective process for treating highly nitrogenous wastewater. However, the fate of organic nitrogen during Anammox treatment is still unclear, which limits its practical application.

Below‐ground drivers of rhizosphere functional gene assembly during Moso bamboo expansion

Functional Ecology, Volume 40, Issue 4, Page 1001-1020, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Moso bamboo (Phyllostachys edulis) expansion threatens subtropical forest biodiversity, yet how intraspecific root trait variation shapes rhizosphere microbial functional potential remains unclear.

Gut Microbiomes of Marine Zooplankton: Consequences for Host Performance, the Biological Carbon Pump, and Prokaryote Biogeography

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Expected effects of zooplankton microbiota on the host and on the ecosystem. Stylized mesozooplankton holobiont (center) with arrows indicating respiration within the gut and export of faecal pellets and associated microbes. Orange bubbles summarise microbiome‐mediated consequences for host performance (digestive help, detoxification, vitamin ...

Hi‐C Links Reveal Viral Activity and Infection Within the Free‐Living Microbial Community of a Secondary Chlorophyll Maximum in the Eastern Tropical North Pacific

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Hi‐C sequencing was used to link viral sequences with microbial metagenome assembled genomes in the largely uncultivated waters of an oxygen‐deficient zone's secondary chlorophyll maximum within the Eastern Tropical North Pacific Ocean. ABSTRACT Oxygen‐deficient zones (ODZs) influence global nitrogen cycling as key sites for the removal of bioavailable
