New Insights in Lifetime Migrations of Albacore Tuna (Thunnus alalunga, Bonnaterre, 1788) between the Southwest Indian and the Southeast Atlantic Oceans Using Otolith Microchemistry Open
To clarify potential trans-oceanic connectivity and variation in the natal origin of albacore tuna (Thunnus alalunga) from the southwest Indian Ocean (SWI) and the southeast Atlantic (SA), lifetime otolith elemental signatures were assesse…

Marine reservoir ages for coastal West Africa Open
We measured the 14C age of pre-bomb suspension-feeding bivalves of known age from coastal West Africa across a latitudinal transect extending from 33∘ N to 15∘ S. The specimens are from collections belonging to the Muséum National d'Histoi…

First survey of metallic distribution in zooplankton from a south Moroccan area Open
The Moroccan Southern Atlantic coast is mainly influenced by upwelling, Saharan dust and anthropogenic micropollutant input. These factors contribute to increasing the availability of metal elements in waters. To differentiate human impact…

Review: No C cycle role in MRA around 1900 AD Open
Abstract. We measured the 14C age of pre-bomb suspension-feeding bivalves of known-age from coastal West Africa (n = 30) across a latitudinal transect extending from 33° N to 15° S. The specimens are from the collections of the Muséum Nati…

Spatiotemporal structure of narrow-barred Spanish mackerel (<i>Scomberomorus commerson</i>) from the Red Sea and western Indian Ocean based on otolith micro-chemistry Open
Though the narrow-barred Spanish mackerel ( Scomberomorus commerson ) is considered to be migratory, the species is nevertheless thought to be locally overexploited in the northwest Indian Ocean. At the regional level, this local depletion…

Investigating natal origins and trans-oceanic migrations in albacore tuna (Thunnus alalunga) from the southwest Indian Ocean using otolith chemistry Open
Variation in otolith elemental fingerprints was investigated in albacore tunas (Thunnus alalunga) sampled in the southwest Indian Ocean (SWI) and along the Atlantic coast of South Africa (SA). A total of 72 otoliths were selected, from 46 …

Habitat use and nursery evaluation for the longnose stingray <i>Hypanus guttatus</i> (Bloch & Schneider, 1801) using vertebral microchemistry Open
Here, we use vertebral microchemistry to investigate the habitat use patterns of the longnose stingray Hypanus guttatus in the northern and northeastern regions of Brazil, and to evaluate the existence of potential nurseries of the species…
View article: Natal origin and migration pathways of Mekong catfish (Pangasius krempfi) using strontium isotopes and trace element concentrations in environmental water and otoliths
Natal origin and migration pathways of Mekong catfish (Pangasius krempfi) using strontium isotopes and trace element concentrations in environmental water and otoliths Open
To improve our knowledge of the migration pathway of a highly threatened fish species along the Mekong River, strontium isotope ratios ( 87 Sr/ 86 Sr) and 18 trace element concentrations were measured in the water and in the otoliths of an…

Age and growth of the bull shark (<span><i>Carcharhinus leucas</i></span>) around Reunion Island, South West Indian Ocean Open
Sharks exhibit varied demographic strategies depending on both the species and the population location, which make them more or less vulnerable to fishing. Accurate evaluation of local age and growth parameters is therefore fundamental for…

Otolith microchemistry suggests probable population structuring in the Indian Ocean for the broadbill swordfish Xiphias gladius Open
Variation in otolith elemental fingerprints was investigated in the broadbill swordfish (Xiphias gladius) to complement genetic data obtained by next generation sequencing in the framework of a collaborative project on population stock str…

Changes in environmental salinity during the life of Pangasius krempfi in the Mekong Delta (Vietnam) estimated from otolith Sr : Ca ratios Open
Pangasius krempfi is a commercially important catfish in the Mekong River and is believed to migrate along the Mekong River basin. To verify this migration, elemental concentrations were measured in the water and in otoliths to infer the s…

Partial migration and early size of southern hake Merluccius australis: a journey between estuarine and oceanic habitats off Northwest Patagonia Open
Partial migration is a key adaptive strategy, increasingly observed across multiple taxa. To investigate partial migration and life-cycle diversity of Merluccius australis in northwestern Patagonia, we analysed isotopic (δ13C, δ18O) and el…

Discrimination of Solea solea nurseries along the French Atlantic coast using otolith elemental signatures Open
The common sole Solea solea (L.) is a commercially important and widely distributed flatfish of the North-East Atlantic. Like most demersal marine fishes around the world, sole stocks suffer from overexploitation. For the Bay of Biscay sto…
