Diatom Transcriptional and Physiological Responses to Changes in Iron Bioavailability across Ocean Provinces
...Phylogeny and species delineation in the marine diatom Pseudo-nitzschia (Bacillariophyta) using cox1, LSU, and ITS2 rRNA...
...Published in Journal of phycology
Analyses of the mitochondrial cox1, the nuclear-encoded large subunit (LSU), and the internal transcribed spacer 2 (ITS2) RNA coding region of Pseudo-nitzschia revealed that the P. pseudodelicatissima complex can be phylogenetically grouped into three distinct clades (Groups I-III), while the P. delicatissima complex forms another distinct clade (G...
Environmental Factors Affecting the Distribution of Pseudo-nitzschia in Two Monsoonal Estuaries of Western India and Eff...
Published in Estuaries and Coasts
Species of the diatom genus Pseudo-nitzschia, some of which produce the neurotoxin domoic acid (DA), were studied to see how environmental factors affect their distribution in two tropical monsoonal estuaries and how salinity influences the growth and toxicity of P. pungens. Pseudo-nitzschia pungens, P. multistriata, and P. seriata were present in ...
Determination of Domoic Acid in Plankton Net Samples from Golden Horn Estuary, Turkey, Using HPLC with Fluorescence Dete...
Published in Bulletin of Environmental Contamination and Toxicology
This study focused on the fluctuations of domoic acid (DA) levels in plankton net samples collected from the Golden Horn Estuary (GHE), Turkey, between August 2011 and July 2012. DA concentrations were determined by high-performance liquid chromatography (HPLC), using a fluorenylmethoxycarbonyl (FMOC) derivatization technique. Monthly and biweekly ...
Can domoic acid affect escape response in copepods?
Copepods are important grazers on toxic phytoplankton and serve as vectors for algal toxins up the marine food web. Success of phytoplankton depends among other factors on protection against grazers like copepods, and same way copepod survival and population resilience relies on their ability to escape predators. Little is, however, known about the...
Pseudo-nitzschia sp. diversity and seasonality in the southern North Sea, domoic acid levels and associated phytoplankto...
The diversity, toxicity and seasonality of Pseudo-nitzschia sp. were investigated from February to November 2012 in the southern Bight of the North Sea (SBNS) along the French coast. The identification of Pseudo-nitzschia species in this area was addressed for the first time in this study. Our results revealed a low species richness (3 distinct spe...
Induction of domoic acid production in diatoms—Types of grazers and diatoms are important
...
Grazers can induce toxin (domoic acid, DA) production in diatoms. The toxic response has been observed in two species of Pseudo-nitzschia and was induced by Calanus copepods. In this study, interactions between diatoms and copepods were further explored using different species of diatoms and copepods. All herbivorous copepods induced toxin producti...
