Biochemical Polymorphism in the Pacific Oyster-III

NIPPON SUISAN GAKKAISHI, 1978
Genetic variations have previously been described in the myogen, est erases, tetrazolium oxidase, and leucine arninopeptidases in the Pacific oyster, Crassostrea gigas. Some 900 specimens (35 lots) of the Pacific oyster, sampled from the wild populations off the Pacific and the Japan Sea coasts of Hokkaido, and off Iwate and Akita Prefectures, as well ...

Entering the Era of Directly Supporting Society With Observation‐Based Ocean Acidification Data

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Ocean acidification is a growing concern for many nations around the world. However, our capacity to monitor changes in carbonate chemistry with sufficient spatial and temporal resolution, has until now, been limited, which has impeded effective action and decision‐making at international, national, and regional levels.

Macroalgae and Bivalve Interactions: A Review of Trophic and Feeding Studies to Assess the Contribution of Macroalgal Detritus to Bivalves

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT There is growing interest in the co‐culture of macroalgae and filter‐feeding bivalves due to anticipated trophic benefits that may enhance the productivity of both organisms. Detritus from cultured macroalgae has the potential to supplement bivalve diets, yet few studies have directly examined this relationship in co‐culture systems.

Monitoring the Colonisation Dynamics of Rugulopteryx okamurae on Algal Communities in the Northwestern Mediterranean Sea

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT Biological invasions are a major driver of biodiversity loss, causing profound and often irreversible ecological changes. Among these invaders, the brown alga Rugulopteryx okamurae provides a striking example. Since its arrival in 2016 in Calanques National Park (Marseille, southern France), it has drastically transformed underwater landscapes

Altered by Gold: A Comparative Zooarchaeological Analysis of 19th to 20th Century Chinese and British Migrants in Ravenswood, a Northern Queensland Gold Mining Town

Archaeology in Oceania, Volume 61, Issue 2, Page 312-333, July 2026.
ABSTRACT Gold discoveries transformed the 19th century British colony of Queensland, Australia, driving migration, a second wave of pastoral expansion northwards, and an increasingly diverse population. This study presents a comparative and contextual zooarchaeological analysis of British and southern Chinese food waste—globally significant migrant ...

Functional Analysis on Shelk2 of Pacific Oyster [PDF]

, 2018
Shelk2, a novel shell matrix protein from the Pacific oyster, Crassostrea gigas, is reported to be involved in shell biosynthesis of the prismatic layer. Results of RNAi experiment on shelk2 showed that Shelk2 has a key role in shell regeneration. When dsRNA of shelk2 was injected into the adductor muscle of Pacific oyster, the prismatic layer did not ...

Wild populations of Pacific oysters (Magallana gigas) emerge during the blob heatwave in south Puget Sound, Washington USA

Frontiers in Marine Science
Marine heatwaves have altered ecosystems globally, including changing community composition and facilitating the spread of invasive species. In south Puget Sound, Washington (USA), non-native Pacific oysters (Magallana gigas) have been farmed extensively

Warming but not Food Limitation Alters Metabolism During Larval Development in Crown‐of‐Thorns Sea Stars (Acanthaster cf. Solaris)

Ecology and Evolution, Volume 16, Issue 7, July 2026.
This work investigates how two factors (food and temperature) affect the metabolic rates of the larval stages of ecologically important coral‐eating crown‐of‐thorns sea star (Acanthaster sp.). Warming increased metabolic rates, with oxygen consumption at raised temperatures compared to control. After accounting for larval size, feeding had no effect on

Temperature Alters Specificity in a Host–Parasite Interaction

Ecology and Evolution, Volume 16, Issue 7, July 2026.
The Red Queen Hypothesis predicts that host–parasite coevolution maintains genetic variation through strong genetic specificity, but this specificity may be sensitive to environmental conditions. Using Meloidogyne arenaria and its parasite Pasteuria penetrans, we tested host–parasite interactions across three temperatures and found specificity at two ...

Revealing genetic diversity, population structure, and selection signatures of the Pacific oyster in Dalian by whole-genome resequencing

Frontiers in Ecology and Evolution
IntroductionThe Pacific oyster (Crassostrea gigas), one of the major aquaculture shellfish worldwide, has strong environmental adaptability. However, genetic diversity and population structure of the Pacific oysters in Dalian Sea, the major natural and ...
