The archaeology of shellfishing practices on Ua Huka, Marquesas Archipelago (French Polynesia)

open access: yesArchaeology in Oceania, Volume 59, Issue 2, Page 251-274, July 2024.
Abstract Shellfish remains are ubiquitous to coastal archaeological sites in the Marquesas but have seldom been the focus of dedicated investigations into their contribution to past diet and daily life. On the island of Ua Huka, in the northern group of the archipelago, people have consumed a variety of shellfish since their arrival on the island ...

Challenging trophic position assessments in complex ecosystems: Calculation method, choice of baseline, trophic enrichment factors, season and feeding guild do matter: A case study from Marquesas Islands coral reefs

open access: yesEcology and Evolution, Volume 14, Issue 7, July 2024.
Abstract Assessments of ecosystem functioning are a fundamental ecological challenge and an essential foundation for ecosystem‐based management. Species trophic position (TP) is essential to characterize food web architecture. However, despite the intuitive nature of the concept, empirically estimating TP is a challenging task due to the complexity of ...

Exploring the Mineral Composition, Structure, and Function of a Freshwater Bivalve Adhesive

open access: yesAdvanced Materials Interfaces, Volume 11, Issue 17, June 17, 2024.
The freshwater oyster, Etheria elliptica, produces a mineralized adhesive consisting of aragonite nanoparticles that are less dense and more crystallographically disordered at the exterior than at the interior of the adhesive. The resulting material has a gradient in hardness and elasticity with the adhesive closest to the exterior being softer and ...

Genetic Effects of Pearl Culture Practices and Recruitment of the Black-Lipped Pearl Oyster (Pinctada margaritifera) in French Polynesia

open access: yes, 2011
French Polynesia relies solely on the collection of wild Pinctada margaritifera spat for pearl oyster culture. This was developed to help protect the wild populations from overexploitation, but it is feared that massive spat collection could lead to ...

Substantial gene expression shifts during larval transitions in the pearl oyster Pinctada margaritifera

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 342, Issue 2, Page 76-84, March 2024.
Larval transition is associated with large shifts in gene expression in Pinctada margaritifera. Abstract Early development stages in marine bivalve are critical periods where larvae transition from pelagic free‐life to sessile mature individuals. The successive metamorphosis requires the expression of key genes, the functions of which might be under ...
