UPLC–MS/MS Identification of Sterol Sulfates in Marine Diatoms

open access: yesMarine Drugs, 2018
Diatoms are unicellular eukaryotic organisms that play a key ecological and biogeochemical role in oceans as major primary producers. Recently, these microalgae have also attracted interest as a promising source of functional products with widespread ...

Industrial Applications of Dinoflagellate Phycotoxins Based on Their Modes of Action: A Review

open access: yesToxins, 2020
Dinoflagellates are an important group of phytoplanktons, characterized by two dissimilar flagella and distinctive features of both plants and animals. Dinoflagellate-generated harmful algal blooms (HABs) and associated damage frequently occur in coastal

Palynology of the Dalichai Formation in the Guydagh section, southeastern Maragheh, according to dinoflagellate [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2018
Introduction The Dalichai Formation is represented by greenish-grey color shales, calcareous shales, marls, and richly ammonitiferous limestones (Steiger, 1966), being widely distributed in the Alborz Mountain, northern Iran.

Bioavailability of Organic Phosphorus Compounds to the Harmful Dinoflagellate Karenia mikimotoi

open access: yesMicroorganisms, 2021
Karenia mikimotoi is one of the most well-known harmful bloom species in temperate coastal waters. The present study investigated the characteristics of alkaline phosphatase (APase) and phosphodiesterase (PDEase) activities in hydrolysis of two ...

A turbulent diatom vs dinoflagellate phytoplankton biomass model [PDF]

open access: yes, 2013
Phytoplankton blooms play an important role in global primary productivity and the dynamics of blooms are of interest to modellers. Diatom dominated phytoplankton blooms followed by dinoflagellate blooms are common in the Southern Benguela, and are often

A critical revision of the fossil record, stratigraphy and diversity of the Neogene seal genus Monotherium (Carnivora, Phocidae) [PDF]

open access: yes, 2018
Historically, Monotherium had been one of the few genera of extinct Phocidae (true seals) that served as a wastebin taxon. Consequently, it did neither aid in understanding phylogenetic relationships of extinct Phocidae, nor in understanding seal ...

Seasonal succession and niche differentiation in Skeletonema species driven by temperature and salinity in inner Tokyo Bay

open access: yesJournal of Phycology, EarlyView.
Abstract The genus Skeletonema is a dominant diatom in coastal waters worldwide, frequently causing blooms, and it includes several cryptic species. To elucidate the occurrence patterns and niche differentiation among Skeletonema species in Tokyo Bay, Japan, sampling was conducted between June 2021 and February 2023.

Simultaneous Effect of Temperature and Irradiance on Growth and Okadaic Acid Production from the Marine Dinoflagellate Prorocentrum belizeanum

open access: yesToxins, 2014
Benthic marine dioflagellate microalgae belonging to the genus Prorocentrum are a major source of okadaic acid (OA), OA analogues and polyketides. However, dinoflagellates produce these valuable toxins and bioactives in tiny quantities, and they grow ...

LC-MS/MS Method Development for the Discovery and Identification of Amphidinols Produced by Amphidinium

open access: yesMarine Drugs, 2020
Amphidinols are polyketides produced by dinoflagellates suspected of causing fish kills. Here, we demonstrate a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the identification and quantification of amphidinols (AM).

Asynchrony of Gambierdiscus spp. Abundance and Toxicity in the U.S. Virgin Islands: Implications for Monitoring and Management of Ciguatera

open access: yesToxins, 2021
Ciguatera poisoning (CP) poses a significant threat to ecosystem services and fishery resources in coastal communities. The CP-causative ciguatoxins (CTXs) are produced by benthic dinoflagellates including Gambierdiscus and Fukuyoa spp., and enter reef ...
