One Bloom Is Not Like the Other—Distinct Environmental Drivers Result in Domoic Acid Events in Monterey Bay, California [PDF]

Toxins
Domoic acid (DA), produced by Pseudo-nitzschia diatoms, is the one of the major toxin threats from harmful algal blooms (HABs) on the west coast of the United States.

Comparative Analysis of Pseudo-nitzschia Chloroplast Genomes Revealed Extensive Inverted Region Variation and Pseudo-nitzschia Speciation

Frontiers in Marine Science, 2022
Pseudo-nitzschia is a species-rich genus where many species can induce harmful algae blooms (HABs) associated with the toxin domoic acid (DA) production.

A New Insight into the Taxonomy of Pseudo-nitzschia Genus from the Adriatic Sea: Description of P. brasiliana, P. galaxiae, P. hasleana, and P. linea

Journal of Marine Science and Engineering, 2023
Marine diatoms of the genus Pseudo-nitzschia are widespread and occur in various environments. About half of the species described today have been shown to be toxic, producing the potent neurotoxin, domoic acid.

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

Marine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

Long-Term Variations in Species Composition of Bloom-Forming Toxic Pseudo-nitzschia Diatoms in the North-Western Sea of Japan during 1992–2015

Journal of Marine Science and Engineering, 2021
This review aimed to summarize original and published data on the bloom events caused by toxic diatoms of the genus Pseudo-nitzschia and to assess long-term variations in the composition of bloom-forming species in the northwestern Sea of Japan during ...

Morphological, molecular and toxigenic characteristics of Namibian Pseudo-nitzschia species – including Pseudo-nitzschia bucculenta sp. nov. [PDF]

Harmful Algae, 2018
A field study was undertaken to investigate the occurrence and toxin production of species in the diatom genus Pseudo-nitzschia in Namibian waters, in the extremely productive Benguela upwelling system. From surveys conducted on the R/V Mirabilis and the R/V !Anichab, 52 strains were morphologically determined to species level, supported by nuclear ITS

Harmful algae diversity from a coastal upwelling system detected by high-throughput sequencing

Frontiers in Marine Science, 2023
IntroductionIn recent years, environmental DNA (eDNA) amplicon sequencing has been used to unveil plankton diversity in the field. Nevertheless, molecular methods, such as this, are rarely used in harmful algal bloom (HAB) monitoring programs, which ...

Stress Response in Toxic Diatoms: The Effects of Abiotic Factors on Growth and RNA Content in Pseudo-nitzschia calliantha and in Pseudo-nitzschia multistriata

Journal of Marine Science and Engineering, 2023
Pennate diatoms belonging to the genus Pseudo-nitzschia are important components of phytoplankton assemblages in aquatic environments. Among them, the bloom-forming species Pseudo-nitzschia calliantha and Pseudo-nitzschia multistriata are known as domoic

Pseudo-Nitzschia sp (Bacillariophyceae), seasonal distribution in the lagoon of Nador (Morroco) [PDF]

E3S Web of Conferences, 2021
The goal of this study is to look into the dominance of diatoms, specifically the genus “Pseudo-Nitzschia Sp” at the Nador lagoon level and how it relates to the physicochemical parameters of the environment.
