Modeling Upper Ocean Ecosystem Dynamics in Response to Interannual Sea‐Ice Variability in the Western Antarctic Peninsula

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract In the Western Antarctic Peninsula (WAP), marine plankton dynamics are tightly linked to the interannual variability in environmental conditions, including phenological shifts in sea‐ice seasonality. To explore these linkages, we use a 1‐dimensional vertical ocean‐ice‐ecosystem model (KPP‐Eco‐Ice, or KEI) that simulates physical and ecosystem ...

From Flames to the Ocean: Biomass Burning Aerosols Are Associated With Changes in Prokaryotic Communities in the Mediterranean Sea

Environmental Microbiology, Volume 28, Issue 4, April 2026.
The addition of wildfire fine ash particles (particle size < 20 μm) in Mediterranean summer seawater can increase prokaryotic growth and alter community composition over time, likely through the release of both inorganic and organic substrates by ash particles and by inducing changes in the composition of phytoplankton populations.

Disentangled Assembly Graphs Reveal Hidden Eukaryotic Diversity in eDNA Metagenomic Data

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Genome assembly graphs contain valuable yet frequently overlooked information that can enhance assembly completeness by revealing contig connectivity. Here, we demonstrate how leveraging these information‐rich structures enables the discovery of hidden microeukaryotic diversity in environmental DNA shotgun metagenomic datasets.

Differences in Prokaryotic Community Composition Between Two Climatically Contrasting Years in an Arctic Fjord Ecosystem

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Seasonal dynamics of prokaryotic communities in Kongsfjorden were driven by contrasting hydrographic conditions in 2019 and 2020. Atlantification enhanced prokaryotic diversity and interactions in 2019, while sea ice and glacial runoff in 2020 reduced surface diversity and network complexity, underscoring Arctic prokaryotic sensitivity to environmental

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions [PDF]

Environ Microbiol Rep
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...
