Climate Change Stressors, Phosphate Limitation, and High Irradiation Interact to Increase Alexandrium minutum Toxicity and Modulate Encystment Rates [PDF]

Microorganisms
The changes in the cell physiology (growth rate, cell size, and cell DNA content), photosynthetic efficiency, toxicity, and sexuality under variable light and nutrient (phosphates) conditions were evaluated in cultures of the dinoflagellate Alexandrium ...

The embryo-oil drop assembly: the timing and morphology of a critical event for fish early-life history survival [PDF]

Scientific Reports
Egg specific gravity is of relevance for fish recruitment since the ability to float influences egg and larvae development, dispersal and connectivity between fishing grounds.

Breaking Boundaries: First Observation of Intertidal Emergence During Mating in Octopuses [PDF]

Ecology and Evolution
Reproductive behaviour in octopuses is diverse, yet field observations remain limited for nocturnal species such as Callistoctopus macropus. We report the first documented case of intertidal emergence during copulation in an octopus.

Growth and survival of Octopus vulgaris (Cuvier 1797) paralarvae fed on three Artemia-based diets complemented with frozen fish flakes, crushed zooplankton and marine microalgae

Scientia Marina, 2011
During one month, paralarvae of common octopus (Octopus vulgaris) were fed 3 different diets: (1) Artemia sp. enriched with Isochrysis galbana (AI) complemented with sand eel (Hyperoplus lanceolatus) flakes (AH); (2) Artemia sp.

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 ...

Spatial variability of life-history parameters of the Atlantic chub mackerel (Scomber colias), an expanding species in the northeast Atlantic

Scientia Marina, 2022
Atlantic chub mackerel is a pelagic species present in the Atlantic Ocean that in recent decades has expanded northwards in the eastern Atlantic. Fish samples were collected in scientific surveys and commercial catches between 2011 and 2019. We analysed

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.
