Dynamics and impacts of toxic Alexandrium catenella blooms in the Pacific Arctic
… Of particular concern is the dinoflagellate Alexandrium catenella, a cystforming species that produces a potent suite of paralytic shellfish toxins (PSTs). In this thesis, Pacific Arctic bloom dynamics are explored in the context of the meroplanktonic life cycle of Alexandrium, revealing the …

Alexandrium catenella cyst dynamics in a coastal embayment : temperature dependence of dormancy, germination, and bloom Initiation
Blooms of the dinoflagellate Alexandrium catenella cause paralytic shellfish poisoning syndrome and present an expanding public health threat. They are inoculated through the germination of benthic cysts, a process regulated by internal and environmental factors, most importantly temperature. Less …

Comparative laboratory study of photoacclimation in selected dinoflagellate and diatom species of the Benguela ecosystem
… responses in five species of dinoflagellates (Alexandrium catenella, Protoceratium reticulatum, Prorocentrum micans, Prorocentrum triestinum, Gymnodinium zeta) and three diatom species (Chaetoceros sp., C. capense, C. cf. pendulus) were investigated with respect to parameters of P versus E …

An Evaluation of the risks to food safety and shellfish farming in Great Britain,posed by marine biotoxins from, current and future emerging, marine microalgal species
… the current extent of a harmful species, Alexandrium minutum, globally and in the South of GB. This shows that A. minutum occurs widely across the globe with different populations possessing varying toxin profiles. Populations from GB geographically neighbouring areas share similar toxin …

Nitrogen nutrition of harmful algal blooms in upwelling systems
… with ƒratios dropping from 0.79 to 0.12. Alexandrium catenella bloomed during a period of upwelling, displaying high (NO3-) and ƒ-ratios up to 0.87. Dinophysis acuminata dominated when NO3<br/>- concentrations were <0.5 ?mol l-1 and ƒ-ratios <0.1 in 2007, although in 2008 it formed a …
