Do shortfin mako Isurus oxyrinchus hunt dolphins actively? [PDF]

J Fish Biol
Abstract Direct evidence of shark predation on cetaceans is scarce, making it difficult to differentiate between stomach contents that have been scavenged and actively hunted. This study reports the presence of dolphin (Tursiops aduncus and Stenella clymene) remains in the stomachs of three large shortfin makos Isurus oxyrinchus.

Integrative taxonomy suggests hidden diversity within the fish genus Cyttopsis (Zeiformes, Parazenidae). [PDF]

J Fish Biol
Abstract Nine specimens of Cyttopsis rosea (Zeiformes: Parazenidae) were collected during scientific surveys at three different locations in the northeast Atlantic. All nine specimens were included in the molecular analysis, adding new cytochrome c oxidase subunit I sequences to public databases.

Methods to estimate marine functional connectivity: A primer. [PDF]

Ecol Appl
Abstract Organism movement is a key process in the transfer of individuals, genes, functional traits, matter, and energy among habitat patches, at sea and across the land–sea interface. The resulting fluxes, collectively termed marine functional connectivity (MFC), underpin planetary health and an array of ecosystem services.

Bivalve Shell Utilization by Juvenile <i>Octopus vulgaris</i> in Sandy Substrates. [PDF]

Ecol Evol
This study investigates how juvenile Octopus vulgaris adapt to sandy environments with limited shelter and high predation risk by using empty bivalve shells for protection. Through four SCUBA expeditions in NW Spain, nine juveniles were observed using shells that fit their body size, strategically positioning themselves for surveillance and employing ...

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.

Complementarity and sensitivity of benthic state indicators to bottom-trawl fishing disturbance. [PDF]

Ecol Appl
Abstract Many indicators have been developed to assess the state of benthic communities and identify seabed habitats most at risk from bottom trawling disturbance. However, the large variety of indicators and their development and application under specific geographic areas and management contexts has made it difficult to evaluate their wider utility ...

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 ...
