Ecossistema costeiro de Aveiro (Portugal): Proliferações de Gymnodinium catenatum e detecção de toxinas PSP [PDF]

, 2008
[POR] As proliferações de Gymnodinium catenatum detectadas na Baía de Lisboa em Agosto de 2005, permitiram confirmar esta zona como epicentro para o início destes blooms, relacionados com a pluma de afloramento do Cabo da Roca.

Rapid sexual reproduction intensifies blooms of a mixotrophic dinoflagellate

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Sexual reproduction is fundamental to the ecology and evolution of eukaryotes, yet its dynamics in microbial eukaryotes are often cryptic. Dinophysis are specialist mixotrophs that must balance prey capture, cell division, and sexual recombination during blooms, but relatively little is known about the occurrence and role of sex in their ...

Environmental governance in the face of collapse: The case of Acapulco, Mexico, between tourist splendour and ecological risk

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Underwater clean‐up efforts in Acapulco Bay reveal the visible consequences of chronic coastal pollution. This study shows how Environmental Risk Assessments (ERAs) can integrate scientific evidence, regulatory frameworks and practitioner experience to identify pollution sources and guide more effective coastal governance in cities of the Global South.

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 ...

Influence of solar and geomagnetic activity in Gymnodinium catenatum (Dinophyceae) cultures

General physiology and biophysics, 2017
Laboratory cultures of the paralytic shellfish poisoning producing microalga Gymnodinium catenatum were subjected to a hypo-osmotic shock and changes in cell concentration were observed in two separate experiments of 8 and 24 hours duration, respectively.

Revealing Seasonal Patterns and Metabolism of Microbial Plankton in a Productive Coastal Upwelling System

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Increasing our knowledge about the structure and metabolism of the microbial plankton community in coastal upwelling systems is essential for efficiently managing the resources of these highly productive ecosystems. Here we explore seasonal variations of this community in the NW Iberian coastal upwelling system by measuring variables informing

Grazer‐induced bioluminescence and toxicity in marine dinoflagellates

Limnology and Oceanography, Volume 70, Issue 12, Page 3769-3783, December 2025.
Abstract Marine copepods are the most abundant multicellular zooplankton in the global oceans. They imprint their surrounding waters with a unique bouquet of chemical compounds, including polar lipids such as copepodamides. Prey organisms can detect copepodamides and respond by inducing defensive traits including bioluminescence, toxin production ...

Comparative paralytic shellfish toxin accumulation in three important Aotearoa New Zealand marine invertebrate species: kina (Evechinus chloroticus), pāua (Haliotis iris) and hohehohe (Panopea zelandica)

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1252-1264, December 2025.
ABSTRACT This study investigated the potential for paralytic shellfish toxin (PST) accumulation in three of Aotearoa New Zealand's (NZ) taonga seafood species: kina (urchin; Evechinus chloroticus), pāua (abalone; Haliotis iris) and hohehohe (geoduck; Panopea zelandica) in laboratory exposures to the dinoflagellate Alexandrium pacificum.
