Distribution of microreticulate dinoflagellate cysts from the Galician and Portuguese coast

Scientia Marina, 1999
In May 1993, surface sediment samples from the west coast of the Iberian Peninsula were collected with the aim of studying the geographic distribution of G. catenatum resting cysts. The sampling area ranged from 40º 39´ N (Portugal) to 42º 38´ N (Galicia,

Microplastics in wild mussels (Mytilus spp.) from the north coast of Spain

Scientia Marina, 2019
Microplastic content (MPs) in mussels (Mytilus spp.) from two areas of the north coast of Spain was measured for the first time. Additionally, a comparison of microplastic levels observed in mussels digested with nitric acid and with potassium hydroxide ...

Notes on the Cultivation of Two Mixotrophic Dinophysis Species and Their Ciliate Prey Mesodinium rubrum

Toxins, 2018
Kleptoplastic mixotrophic species of the genus Dinophysis are cultured by feeding with the ciliate Mesodinium rubrum, itself a kleptoplastic mixotroph, that in turn feeds on cryptophytes of the Teleaulax/Plagioselmis/Geminigera (TPG) clade.

Discards of Spanish trawler fleets operating in the Bay of Biscay in 2000

Scientia Marina, 2006
A stratified sampling programme by gear and port was carried out by observers on board vessels in 2000 to study the discard behaviour of trawler fleets operating off Spanish North Atlantic coasts. No relationship between discards in weight or numbers and

Ciguatera-Causing Dinoflagellate Gambierdiscus spp. (Dinophyceae) in a Subtropical Region of North Atlantic Ocean (Canary Islands): Morphological Characterization and Biogeography

Toxins, 2019
Dinoflagellates belonging to the genus Gambierdiscus produce ciguatoxins (CTXs), which are metabolized in fish to more toxic forms and subsequently cause ciguatera fish poisoning (CFP) in humans. Five species of Gambierdiscus have been described from the

Culture viability of Sardina pilchardus (Fish, Teleost): Preliminary results of growth in captivity up to 18 months

Scientia Marina, 2014
Larvae of Sardina pilchardus were obtained in captivity from fertilized eggs captured in the wild and grown in a 10000-L tank. Isochrysis galbana, Artemia franciscana nauplii and live zooplankton were used as prey during the first two weeks; afterwards ...

Empirical leucine-to-carbon conversion factors in north-eastern Atlantic waters (50–2000 m) shaped by bacterial community composition and optical signature of DOM

Scientific Reports, 2021
Microbial heterotrophic activity is a major process regulating the flux of dissolved organic matter (DOM) in the ocean, while the characteristics of this DOM strongly influence its microbial utilization and fate in the ocean.
