How Does Climate Change Influence the Regional Ecological-Social Risks of Harmful Dinoflagellates? A Predictive Study of China's Coastal Waters. [PDF]

Glob Chang Biol
Climate change is expected to shift the risks posed by harmful dinoflagellates in China's coastal waters. In this study, the ecological–social risk is assessed by considering both the potential presence of these algae and their overlap with coastal populations and mariculture areas.

Twenty-Five Years of PSP Toxicity in Galician (NW Spain) Bivalves: Spatial, Temporal, and Interspecific Variations [PDF]

Toxins, 2022
Twenty-five years of paralytic shellfish poisoning (PSP) toxicity in Galician bivalves have been studied. PSP was detected in 4785 out of 73,740 samples of the commercially important bivalve species analyzed from 1995 to 2020.

Widespread presence of hydrophobic paralytic shellfish toxins in Gymnodinium catenatum

Harmful Algae, 2007
The toxic dinoflagellate Gymnodinium catenatum Graham produces a newly discovered sub-class of paralytic shellfish toxins (PSTs, saxitoxins) that contain a hydroxybenzoate moiety in place of the carbamoyl group (GC toxins: GC1–GC3). GC toxins bind strongly to sodium channels and their lipophilic nature may increase their potential to bioaccumulate in ...

Efecto de la comunidad bacteriana en el crecimiento, pigmentos y toxinas paralizantes en el dinoflagelado Gymnodinium catenatum (Graham)

Ciencias Marinas
Gymnodinium catenatum, un dinoflagelado productor de toxinas paralizantes, es una de las especies de dinoflagelados más estudiadas, sin embargo, poco se conoce sobre sus interacciones con bacterias.

Removal and Temporary Cyst Formation of Gymnodinium catenatum (Dinophyceae) Using Calcium Bentonite Clay and Zeolite

Phycology
Clay minerals and other flocculants are used to mitigate the effects of some species that produce harmful algal blooms due to their physical and chemical characteristics.

Algal-bacterial interactions: a study of Gymnodinium catenatum and its associated bacteria

, 2011
Over the last decades, harmful algal blooms (HABs) have increased globally in both frequency and extent, leading to intensified efforts to determine the primary factors that are controlling the population and toxin dynamics of bloom-forming algal species. One poorly understood factor in HAB ecology, yet shown to be of great importance, is that of algal-

Three Novel Hydroxybenzoate Saxitoxin Analogues Isolated from the Dinoflagellate Gymnodinium catenatum

Chemical Research in Toxicology, 2003
In a recent survey of paralytic shellfish poisoning (PSP) toxins in Gymnodinium catenatum Graham extracts, using LC with postcolumn oxidation and fluorescence detection, three novel saxitoxin analogues were revealed in isolates from several locations, including Australian waters. We have named them as G. catenatum toxins, GC1 (1), GC2 (2), and GC3 (3).

Seeding of Gymnodinium catenatum blooms in Iberian shelf waters

, 2014
No abstracts are to be cited without prior reference to the author. Gymnodinium catenatum blooms in the Iberian upwelling system are highly variable at the decadal, annual and event scales. Species-specific life-cycle transitions are probably one of the key factors determining this variability. We investigated the presence of G.

Bacterial Associates Modify Growth Dynamics of the Dinoflagellate Gymnodinium catenatum. [PDF]

Front Microbiol, 2017
Marine phytoplankton cells grow in close association with a complex microbial associate community known to affect the growth, behavior, and physiology of the algal host. The relative scale and importance these effects compared to other major factors governing algal cell growth remain unclear.
