Prism substructures in the shell of Pinna nobilis (Linnaeus, 1758), Mollusca – Evidence for a three-dimensional pulsed-growth model
(Elsevier, 2020-07-20)
In the shells of the Pelecypods belonging to the Pinnidae family, the calcareous prismatic units of the outer layer are long-standing references for biomineralization studies. To elucidate how the ...
Recruitment disruption and the role of unaffected populations for potential recovery after the Pinna nobilis mass mortality event
(Frontiers Media, 2020-10-29)
A devastating mass mortality event (MME) very likely caused by the protozoan Haplosporidium pinnae first detected in 2016 in the Western Mediterranean Sea, is pushing the endemic bivalve Pinna nobilis ...
Toxicity characterisation of Gambierdiscus species from the Canary Islands
(MDPI, 2020-02-21)
In the last decade, several outbreaks of ciguatera fish poisoning (CFP) have been reported in the Canary Islands (central northeast Atlantic Ocean), confirming ciguatera as an emerging alimentary risk ...
Ripe for reassessment: a synthesis of available molecular data for the speciose diatom family Bacillariaceae
(Elsevier, 2020-10-13)
The Bacillariaceae is a very species-rich family of raphid diatoms and includes the large and taxonomically difficult genus Nitzschia, whose species are often small-celled and finely structured and have ...
Growth of juvenile Pinna nobilis in captivity conditions: Dietary and pathological constraints
(Elsevier, 2020-02-25)
The fan mussel, Pinna nobilis, is an endemic Mediterranean species, whose populations have been seriously affected by infectious diseases. The effect of diet composition on growth and survival rates, ...
Environmental typology of rivers from the Brazilian semiarid as a first step for the application of the index of biotic integrity: The case of the Chapada Diamantina
(Wiley, 2020-03-02)
