Article
Full-text available
Pearl-farming is the second most important source of income in French Polynesia. However, tropical lagoons are fragile ecosystems with regard to anthropogenic pressures like plastic pollution, which threaten marine life and the pearl oyster-related economy. Here, we investigated the spatial distribution of microplastics (MP) and concentrations in s...
Article
Full-text available
A combined approach integrating bioenergetics and major biological activities is essential to properly understand the impact of microplastics (MP) on marine organisms. Following experimental exposure of polystyrene microbeads (micro-PS of 6 and 10 μm) at 0.25, 2.5, and 25 μg L⁻¹, which demonstrated a dose-dependent decrease of energy balance in the...
Article
Full-text available
Pearl-farming leads to significant plastic pollution in French Polynesia (FP) as the end of life of most farming gear is currently poorly managed. Plastic debris released into the aquatic environment accumulates, with potentially detrimental effects on the lagoon ecosystem and pearl oyster Pinctada margaritifera, a species of ecological, commercial...
Article
Full-text available
Plastic pollution in the environment is increasing at global scale. Microplastics (MP) are derived from degradation of larger plastic items or directly produced in microparticles form (<5 mm). Plastics, widely used in structures and equipments of pearl farming, are a source of pollution to the detriment of the lagoon ecosystem. In order to evaluate...

Project
The goal of this project is to study the spatial and seasonal variations in the microbiome of recifal species (A. millepora, D. aruanus, P. margaritifera) according to an anthropogenic activity gradient in the pearl-farming atoll lagoon of Ahe (French Polynesia).
Project
The goals of this project were to assess microplastic contamination in pearl-farming lagoons of French Polynesia and to investigate their effects on the pearl oyster (Pinctada margaritifera) in laboratory conditions.
