A widespread picornavirus affects the hemocytes of the noble pen shell (Pinna nobilis), leading to its immunosuppression
(Frontiers, 2023-12-13)
Introduction: The widespread mass mortality of the noble pen shell (Pinna nobilis) has occurred in several Mediterranean countries in the past 7 years. Single-stranded RNA viruses affecting immune cells ...
Nitzschia fenestralis: A new diatom species abundant in the Holocene sediments of an eastern African crater lake
(Czech Phycological Society, 2020-02-18)
Nitzschia is common in the phytoplankton of several East African lakes. A new species, Nitzschia fenestralis, sp. nov. D. Grady, D.G. Mann et Trobajo was encountered at numerous depths in a 16 m sediment ...
Ciguatoxin-like toxicity distribution in flesh of amberjack (Seriola spp.) and dusky grouper (Epinephelus marginatus)
(Elsevier, 2023-04-10)
Ciguatoxins (CTXs) are marine neurotoxins that cause ciguatera poisoning (CP), mainly through the consumption of fish. The distribution of CTXs in fish is known to be unequal. Studies have shown that ...
Suspended culture of Pinna rudis enhances survival and allows the development of a seasonal growth model for Mediterranean Pinnids
(Elsevier, 2021-05-25)
A two-year growth study of 80 Pinna rudis individuals was conducted in offshore cages in the western Mediterranean Sea. A Von Bertalanffy growth model was fitted to monthly measured data of 40 individuals ...
Short-Term Response of Chlorophyll a Concentration Due to Intense Wind and Freshwater Peak Episodes in Estuaries: The Case of Fangar Bay (Ebro Delta)
(MDPI, 2021-03-05)
Estuaries and coastal bays are areas of large spatio-temporal variability in physical and biological variables due to environmental factors such as local wind, light availability, freshwater inputs or ...
Inheritance of spheroid body and plastid in the raphid diatom Epithemia (Bacillariophyta) during sexual reproduction
(Taylor and Francis, 2021-04-21)
Diatoms belonging to the family Epithemiaceae have endosymbiont ‘spheroid bodies’, which have received attention as a model to provide new insights into the early stages of organelle evolution. Uniparental ...
Diversity and regional distribution of harmful algal events along the Atlantic margin of Europe
(Elsevier, 2021-02-12)
The IOC-ICES-PICES Harmful Algal Event Database (HAEDAT) was used to describe the diversity and spatiotemporal distribution of harmful algal events along the Atlantic margin of Europe from 1987 - 2018. ...
Sellaphora mayrii (Bacillariophyceae), a new diatom from the Argentinean Patagonia
(Magnolia Press, 2020-03-26)
A new species of Sellaphora was found in modern and fossil sediments from shallow-lake Laguna Gemelas Este, Santa Cruz, Argentina. The new taxon was studied with light microscopy and scanning electron ...
Planktic diatom responses to spatiotemporal environmental variation in high-mountain tropical lakes
(Wiley, 2024-01-18)
1. Tropical lakes harbour high levels of biodiversity, but the temporal and spatial variability of biological communities are still inadequately characterised, making it difficult to predict the impact ...
Identification of New CTX Analogues in Fish from the Madeira and Selvagens Archipelagos by Neuro-2a CBA and LC-HRMS
(MDPI, 2022-03-29)
Ciguatera Poisoning (CP) is caused by consumption of fish or invertebrates contaminated with ciguatoxins (CTXs). Presently CP is a public concern in some temperate regions, such as Macaronesia (North-Eastern ...
