(MDPI, 2021-08-20)
The Selvagens Islands, which are a marine protected area located at the southernmost point of the Portuguese maritime zone, have been associated with fish harboring ciguatoxins (CTX) and linked to ...
Can we save a marine species affected by a highly infective, highly lethal, waterborne disease from extinction?
(Elsevier, 2020-03-18)
Anthropogenic drivers and global warming are altering the occurrence of infectious marine diseases, some of which produce mass mortalities with considerable ecosystemic and economic costs. The Mediterranean ...
Reproduction of the endangered fan mussel Pinna nobilis under natural and captivity conditions
(Wiley, 2023-09-05)
1. A mass mortality event that started in 2016 has put the fan mussel Pinna nobilis close to the brink of extinction, leading to the species being classified as Critically Endangered in the Red List of ...
A smartphone-controlled amperometric immunosensor for the detection of Pacific ciguatoxins in fish
(Elsevier, 2021-12-02)
Ciguatoxins (CTXs) are marine neurotoxins produced by microalgae of the genera Gambierdiscus and Fukuyoa. CTXs may reach humans through food webs and cause ciguatera fish poisoning (CFP). An immunosensor ...

Nitzschia captiva sp. nov. (Bacillariophyta), the essential prey diatom of the kleptoplastic dinoflagellate Durinskia capensis, compared with N. agnita, N. kuetzingioides and other species
(Taylor & Francis Group, 2023-03-13)
Durinskia capensis is a kleptoplastic dinoflagellate species from high intertidal marine rock pools, which can use a variety of diatoms for photosynthesis. However, very few of the diatoms permit ...
Greenhouse gas emissions and mitigation in rice agriculture
