Diagenetic isotope exchange in biocalcites for paleoclimate reconstruction

The oxygen isotope compositions of fossil biocalcites, such as foraminifera, bivalves, brachiopods, and belemnites have allowed for reconstructions of sea surface and deep ocean temperatures throughout the Phanerozoic and constitute the most important reco ...

Fate and effects of microplastic particles in a periphyton-grazer system

Kristin Schirmer, Ahmed Tlili, Renata Behra

In the aquatic environment, microplastic particles (MP) can accumulate in microbial communities that cover submerged substrata, i.e. in periphyton. Despite periphyton being the essential food source for grazers in the benthic zones, MP transfer from periph ...

Responses of reef bioindicators to recent temperature anomalies in distinct areas of the North Ari and Rasdhoo atolls (Maldives)

Arthur Adams, Aurélie Angéloz, Anaël Lehmann

Assessments of reef sediments in the North Ari Atoll (Maldives) were conducted in 2015 and 2018 on reefs of three islands with different management strategies: community, resort, and uninhabited. Indices applied were the Foraminifera in Reef Assessment and ...

Effect thresholds of metals in stream sediments based on in situ oligochaete communities

Benoît Jean Dominique Ferrari, Régis Lionel Vivien

Aquatic oligochaetes, comprising a large number of species showing various degrees of resistance to chemical pollution, are recognized as valuable bioindicators of sediments’ quality. In the Geneva area (Switzerland), oligochaete tools were previously test ...

Simultaneous preservation of the DNA quality, the community composition and the density of freshwater oligochaetes for the development of genetically based biological indices

Régis Lionel Vivien

Introduction. Oligochaetes are recognized as valuable bioindicators of sediment quality in streams and lakes. The development of an oligochaete index based on the identification of specimens using DNA barcodes requires a method for simultaneously preservin ...

Convergent evolution of complex regulatory landscapes and pleiotropy at Hox loci

Denis Duboule, Fabrice Daniel Darbellay, Nicolas Lonfat

Hox genes are required during the morphogenesis of both vertebrate digits and external genitals. We investigated whether transcription in such distinct contexts involves a shared enhancer-containing landscape. We show that the same regulatory topology is u ...

Towards Estimation of Frontcrawl Energy Expenditure Using the Wearable Aquatic Movement Analysis System (WAMAS)

Kamiar Aminian, Grégoire Millet, Farzin Dadashi, Florent Crettenand

Inertial measurement unit (IMU) is a promising tool in the quantification of energy expenditure for human on-land activities, though has never been deployed before to calculate the aquatic activities energy expenditure. Investigating the factors that influ ...

A Layered Structure in the Organic Envelopes of the Prismatic Layer of the Shell of the Pearl Oyster Pinctada margaritifera (Mollusca, Bivalvia)

Anders Meibom

The organic interprismatic layers of the mollusc Pinctada margaritifera are Studied using a variety of highly spatially-resolved techniques to establish their composition and structure. Our results show that both the interlamellar sheets of the nacre and i ...

Structure and composition of the nacre-prisms transition in the shell of Pinctada margaritifera (Mollusca, Bivalvia)

Anders Meibom

A microstructural, mineralogical, and chemical study of the nacre-prisms boundary in the shells of Pinctada margaritifera shows that this boundary is not an abrupt transition, but that there exists a distinct fibrous layer with clear topographic structures ...
