Recent change in spatial distribution of the European flat oyster (Ostrea edulis) inferred from field data and empirical models of living oysters and empty shells

Ecology and Evolution, 2022
Marine coastal areas are increasingly affected by human activities resulting in changes in species and habitat distributions. Understanding these patterns and its causes and consequences is important for conservation and restoration of such changing ...

Ten priority questions for increasing the consistency and success in hatchery production of the European flat oyster for habitat restoration

Aquatic Living Resources, 2023
The European flat oyster, Ostrea edulis, once formed extensive reef habitats throughout European seas and estuaries. These reefs are now largely functionally extinct, yet interest and support for their restoration is rapidly growing.

‘The big chunky belemnite’: a new relict megateuthidid from the Oxfordian (Late Jurassic) of Wyoming, USA, and its place in the evolutionary history of the group

Papers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract We describe and discuss two finds of large and untypical belemnite rostra originating from the upper part of the Sundance Formation (Oxfordian) of Wyoming, USA. With a diameter reaching c. 60 mm at the anterior end, these rostra are the thickest known for belemnites so far.

Detection of Bonamia ostreae and B. exitiosa (Haplosporidia) in Ostrea edulis from the Adriatic Sea (Italy) [PDF]

Diseases of Aquatic Organisms, 2010
The flat oyster Ostrea edulis L. is widespread along the Italian coasts. In particular, the Manfredonia Gulf (Adriatic Sea) represents an important site where natural beds subsist. Previous monitoring conducted in 1990 by light microscopy and ultrastructural studies revealed the presence of Bonamia-like microcell parasites in some flat oysters ...

Temperature, but not acidification, influences the growth and lipid profile of juvenile sand whiting, Sillago ciliata (Cuvier 1829)

Journal of Fish Biology, Volume 109, Issue 3, Page 1507-1516, September 2026.
Abstract Seafood provides an essential source of macro‐ and micronutrients for coastal communities worldwide. Climate change is a key threat to seafood security, altering the sizes, abundances, distributions, physiology and ecological interactions of fisheries species, and increasingly, there is evidence of impacts to seafood nutritional quality.

Can the protozoan parasite Bonamia ostreae infect larvae of flat oysters Ostrea edulis? [PDF]

Veterinary Parasitology, 2011
Bonamia ostreae is an intracellular protistan parasite affecting flat oysters Ostrea edulis. It can be detected in juveniles but mortalities mainly affect oysters which are more than 2 years old. The parasite is usually observed inside haemocytes and sometimes free, notably in gill epithelia suggesting a parasite release through this organ.

Salinity stress cross-tolerance of Ostrea lurida after exposure to acidified ocean conditions in a simulated freshet discharge

, 2023
Ocean acidification is widely regarded as a serious danger to marine organisms, especially calcifying invertebrates, but how this might interact with other abiotic stressors in realistic environmental events is less well modeled.

Changes to the benthic assemblage associated with mollusc and seaweed cultivation in the Quempillén estuary, north patagonia, Chile Cambios bentónicos asociados a los cultivos de moluscos y de algas del estuario Quempillén en la patagonia norte de Chile

Gayana, 2010
The main aquaculture activities in the Quempillen estuary involve cultures of oysters, Ostrea chilensis and algae Gracilaria chilensis. Anthropogenic intervention inside the estuary generates significant changes in sediments and organic matter content ...

Spatiotemporal variation of some metal concentrations in oysters from the Mali Ston Bay, south-eastern Adriatic, Croatia - potential safety hazard aspect

Veterinární Medicína, 2007
The concentrations of cadmium, lead and zinc were determined in the soft tissue of oysters (Ostrea edulis L.) from three locations in the Mali Ston Bay on the south-eastern coast of the Adriatic Sea.
