Seasonal and Geologic Controls on Submarine Groundwater Discharge‐Derived Nutrient Fluxes to Two Coastal Embayments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Submarine groundwater discharge and porewater exchange are critical but often overlooked sources of nutrients to coastal systems. This study investigates how sediment permeability and summer‐winter seasonal dynamics influence the magnitude and biogeochemistry of nutrient fluxes from submarine groundwater discharge and porewater exchange ...

Next generation sequencing–driven genomic and transcriptomic profiling of Karenia spp. in Gulf and Middle Eastern environments: diversity, toxin potential, and management

Frontiers in Marine Science
Harmful Algal Blooms (HABs) of the Karenia spp. present an escalating threat to the desalination infrastructure and aquaculture sectors of the Arabian Gulf (AG) and Middle East.

Tracking via Coccolith Assemblages the East Asian Monsoon and Carbonate Production in the South China Sea During Termination II and Marine Isotope Stage 5e

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Coccolith assemblages from the last 158 kyr, encompassing Marine Isotope Stage (MIS) 5e (130–116 kyr) and preceding deglaciation (Termination II; T‐II), offer important insights about current and future climate changes. The South China Sea (SCS) represents a perfect area for reconstructing past East Asian Monsoon (EAM) dynamics thanks to its ...

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.

Deciphering the Neurotoxic Effects of Karenia selliformis

Toxins
Karenia selliformis is a globally recognized dinoflagellate associated with harmful algal blooms and massive fish kills along southern Chilean coasts. Its toxicity varies with environmental factors and genetic diversity. While K.

Morphology of Hobagella saltata n. gen. and n. sp. (Syndiniophyceae, Miozoa) infecting the marine dinoflagellate Cucumeridinium coeruleum (Dinophyceae, Miozoa) and its potential onshore advection

Frontiers in Marine Science
Over the past decade, molecular phylogenies have placed endoparasites of the genus Euduboscquella in a distinct subclade within clade 4 of the Marine Alveolate (MALV) Group I.

Tracing the early development of harmful algal blooms with the aid of Lagrangian coherent structures

, 2007
Several theories have been proposed to explain the development of harmful algal blooms (HABs) produced by the toxic dinoflagellate \emph{Karenia brevis} on the West Florida Shelf.

Coexistence of Photosynthetic Marine Microorganisms, Viruses and Grazers: Towards Integration in Ocean Ecosystem Models

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Our study explores coexistence regimes of a virus and a zooplankton with a single phytoplankton for different model structures (left panel). The inclusion of an infected class and a resistant class is sufficient to generate coexistence regimes (middle panel). Using algebraic solutions, we optimise our model emphasising the importance of including viral

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.

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

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
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 ...
