Unknown Extracellular and Bioactive Metabolites of the Genus Alexandrium: A Review of Overlooked Toxins

Toxins, 2021
Various species of Alexandrium can produce a number of bioactive compounds, e.g., paralytic shellfish toxins (PSTs), spirolides, gymnodimines, goniodomins, and also uncharacterised bioactive extracellular compounds (BECs).

Stable Bacterial Cores and Patchy Eukaryotic Communities Shape the Summer Microbiomes of Patagonian Fjord Ecosystems Across Spatial, Functional and Temporal Gradients [PDF]

Environ Microbiol Rep
Our study shows that microbial community diversity in Patagonian fjords varies with glacial influence and salinity, with a widespread bacterial core but a patchier eukaryotic core. Distinct co‐occurrence networks and marked short‐term community shifts occur in water‑ versus land‐terminating glacier fjords, underscoring meltwater influence in this ...

Biogeochemical, sedimentological and dinoflagellate‐based reconstruction of the Holocene palaeoenvironment of the east Limfjord, Denmark

Boreas, EarlyView.
To assess how the eastern part of the Limfjord system has changed over the Holocene, relative to the wider Limfjord and western Baltic region, a sedimentary succession spanning c. 9600–150 cal. a BP was collected from Nibe Bredning, near Sebbersund, from a shallow coastal inlet along the eastern connection between the Limfjord and the Kattegat (north ...

Morphology of Hobagella saltata n. gen. and n. sp. (Syndiniophyceae, Miozoa) infecting the marine dinoflagellate Cucumeridinium coeruleum (Dinophyceae, Miozoa) and its potential onshore advection

Frontiers in Marine Science
Over the past decade, molecular phylogenies have placed endoparasites of the genus Euduboscquella in a distinct subclade within clade 4 of the Marine Alveolate (MALV) Group I.

Pejerrey (Odontesthes bonariensis) Under Siege: Main Infectious Diseases and Their Role in Aquaculture and Wild Populations Amidst Environmental Change

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.

Overlooked components of lipid metabolism: Odd‐chain polyunsaturated fatty acids in photosynthetic microorganisms

Journal of Phycology, EarlyView.
Abstract This mini‐review examines odd‐carbon polyunsaturated fatty acids (odd‐PUFAs), a rare but biologically significant group of fatty acids in photosynthetic microorganisms. Odd‐PUFAs are straight‐chain fatty acids containing an odd number of carbon atoms and two or more methylene‐interrupted double bonds. They typically account for less than 1% of

The Distribution and Diversity of Dinoflagellate Cysts in Sediments of Gwatar Bay (Northeast Gulf of Oman)

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2015
Most dinoflagellate produce resting cysts during their sexual lifecycle as well as under unfavorable environmental conditions and from water column settle in the sediments substratum. The evaluation of diversity and distribution of dinoflagellate cysts

Earlier spring may explain dominance of the slow‐growing dinoflagellate Naiadinium polonicum over the cyanobacterium Microcystis during a heatwave

Journal of Phycology, EarlyView.
Abstract Global warming and extreme weather events have been linked to a rise in cyanobacterial blooms, which threaten water quality and ecosystem services. However, during an extreme hot and dry summer, Microcystis was outcompeted by a dinoflagellate, Naiadinium polonicum, in a drinking water lake in southern Sweden.

Improved primary production and gross respiration measurements using the H218O technique with membrane inlet mass spectrometry and introduction of a small volume–uniform irradiance incubation chamber

Journal of Phycology, EarlyView.
Abstract An improvement in the H218O technique for phytoplankton gross primary productivity (GPP), net primary productivity (NPP), and gross respiration (GR) is described that reduces cost, labor, and time over the traditional isotope ratio mass spectrometer (IRMS) method.

Analysis of Dinoflagellate Species Distribution in the Puget Sound and their Environmental Conditions from 2015-2022

, 2022
Marine dinoflagellates live in conditions that if changed, can create dangerous environments promoting harmful algae blooms (HABs). This study investigates the drivers of species distribution and bloom peaks using data from the Puget Sound Marine ...
