Filling Biodiversity Knowledge Gaps: Sponges (Porifera: Demospongiae) Recorded off San Jorge Gulf (Argentina), SW Atlantic Ocean

open access: yesBiology and Life Sciences Forum, 2022
The invertebrate by-catch of the Argentinean squid Illex argentinus collected by bottom trawls off San Jorge Gulf during an expedition performed in December 2020 was employed to characterize the bottom assemblages of the area, with special emphasis on ...

Spatial distribution of Illex argentinus in San Matias Gulf (Northern Patagonia, Argentina) in relation to environmental variables: A contribution to the new interpretation of the population structuring [PDF]

open access: yes, 2013
Traditionally, it was assumed that major spawning activity of Illex argentinus occurs in discrete pulses along the outer-shelf/slope off Argentina/southern Brazil during late-fall/winter and that early life stages develop near the Brazil–Malvinas ...

Modelling the selective effects of fishing on reproductive potential and population structure of squid [PDF]

open access: yes, 1994
Artificial selection processes associated with harvesting may operate over relatively short time scales in short-lived semelparous species. The ommastrephid squid Illex argentinus on the Patagonian Shelf is the target of a major fishery.

Distribution and abundance of early life stages of squid (Illex argentinus) in the south-west Atlantic [PDF]

open access: yes, 1992
A joint research cruise (Japan-Argentina-Uruguay) was carried out in the South-western Atlantic during August-September 1989 in order to study the winter-spawning and hatchery areas of Illex argentinus, and also the migration pattern of the juveniles ...

Dietary Shifts and Risks of Artifact Ingestion for Argentine Shortfin Squid Illex argentinus in the Southwest Atlantic

open access: yesFrontiers in Marine Science, 2021
Cephalopods play an important role in both ecology and fisheries. Variations in the dietary compositions of squids with large populations further promote interactions between different trophic levels in marine ecosystems.

The palaeobiology of belemnites – foundation for the interpretation of rostrum geochemistry

open access: yesBiological Reviews, Volume 95, Issue 1, Page 94-123, February 2020., 2020
ABSTRACT Belemnites are an extinct group of Mesozoic coleoid cephalopods with a fossil record ranging from the early Late Triassic [about 240 million years ago (Mya)] to the Cretaceous/Palaeogene boundary (65 Mya). Belemnites were widely distributed, highly abundant and diverse, and an important component of Mesozoic marine food webs.

Cephalopods in the north-eastern Atlantic: Species, biogeography, ecology, exploitation and conservation [PDF]

open access: yes, 1977
Cephalopods play a significant role in coastal and oceanic ecosystems, both as consumers of invertebrates and small fish and as the prey of some fish, seabirds and marine mammals and other large predators. Approximately 30 species of cephalopod have been
