The aims of this study were firstly, to determine if the removal of heads and storage in a modified atmosphere (MA) extended the sensory shelf-life of chilled shell-on cooked Northern shrimp (Pandalus borealis). Secondly, the safe shelf-life of products was determined in regard to Listeria monocytogenes. Shrimp were kept whole or as tails (head region removed) at 5°C in laminar-film-bags with or without MA (40% CO2/60% N2) for 21 days. Analyses i [...]

Soil and the threats it faces nowadays are often underestimated by citizens. This is rather due to a lack of awareness than to a lack of interest. In France, the surface covered by private gardens is not negligible, as it represents 2% of the territory, which is four times larger than the area of natural reserves in the country. Therefore, ensuring the protection and preservation of healthy soils in these areas is of great importance. Citizen sci [...]

Ce travail est réalisé dans le cadre du projet de recherche et développement GELATINE (« GELATinous plankton INdicators for Ecological status assessment » 2021-2023 – Projet R&D entre l’OFB, Sorbonne Université - BOREA et Ifremer ; OFB.21.0105) dont un des objectifs est d’analyser et d’évaluer la pertinence des données de zooplancton gélatineux issues des campagnes halieutiques optimisées pour la DCSMM pour alimenter les indicateurs du bon état é [...]

The taxonomy of majid spider crabs collected from recent southwest Indian Ocean cruises belonging to Eurynome Leach, 1814, and allied genera is treated. Eurynome longimana Stimpson, 1857, long synonymised with the European E. aspera (Pennant, 1777), is here recognised as a distinct species. Stimpson's (1857) species can be distinguished by the armature of granules on the third maxilliped, proportions and armature of the ambulatory merus, relative [...]

A new alpheid shrimp genus, Crosnierocaris gen. nov., is established for Crosnierocaris athanasoides sp. nov., a very peculiar shrimp possibly associated with decomposing sea grass accumulations in deeper water. The type series of C. athanasoides sp. nov. was collected in the Mozambique Channel, north of Grande Glorieuse Island, at a depth of 240-255 m. The new genus presents a unique combination of morphological features, including the very long [...]

Echinoids are key components of modern marine ecosystems. Despite a remarkable fossil record, the emergence of their crown group is documented by few specimens of unclear affinities, rendering their early history uncertain. The origin of sand dollars, one of its most distinctive clades, is also unclear due to an unstable phylogenetic context. We employ 18 novel genomes and transcriptomes to build a phylogenomic dataset with a near-complete sampli [...]

Depuis sa fondation en 1793 le Muséum national d'Histoire naturelle de Paris a intégré les spécimens types de 441 espèces et sous-espèces d'astéries. Le catalogue commenté de tous ces taxons est dressé ici, y compris les espèces dont le matériel type n'a pu être retrouvé dans la collection. Aujourd'hui le muséum de Paris conserve 1011 spécimens types d'astéries représentant 398 espèces et sous-espèces nominales. Décrites principalement par Lamarc [...]

The spiny spider crab, Samadinia pulchra (Miers in Tizard, Moseley, Buchanan & Murray, 1885) (type locality: Bohol Sea, Philippines) has long been considered to be widespread in the western Pacific and Indian Ocean, with Anamathia livermorii Wood-Mason in Wood-Mason & Alcock, 1891, described from the Andaman Sea, in its synonymy. Reassessment of Samadinia pulchra from throughout its purported range indicates that it comprises a complex of three s [...]

Based on molecular and conchological features, a new genus, Bouchetaria, is proposed for the Cypraeidae species Nesiocypraea aenigma Lorenz 2002. Molecular analysis of cox1 and 16S genes places Bouchetaria within a monophyletic group-composed of the genera Propustularia, Nesiocypraea, Ipsa, Perisserosa, Cryptocypraea, and Nucleolaria- appearing as the sister group to all other living Cypraeidae. This group corresponds to the Erosariinae (sensu Lo [...]

Introduction: Since its introduction about a decade ago, target enrichment sequencing of ultraconserved elements (UCEs) has proven to be an invaluable tool for studies across evolutionary scales, and thus employed from population genetics, to historical biogeography as well as deep-time phylogenetics. Here, we present the first probe set targeting UCEs in crustaceans, specifically designed for decapods and tested beyond decapods in other malacost [...]

Unravelling the evolutionary history of taxa requires solid delimitation of the traits characterising these. This can be challenging especially in groups with a highly complex taxonomy. The squat lobster family Munididae contains more than 450 species distributed among 21 genera, Munida being the most speciose (similar to 300 species). Previous phylogenetic studies, based on a small part of the diversity of the group, have suggested polyphyletic [...]

Background Caryophylliidae is one of the most diverse scleractinian families, however it was recovered as polyphyletic in multiple molecular studies. Recently, the mitochondrial gene order was proposed as a character for a taxonomic revision of the family. Here we describe the first mitogenome of the caryophylliid genus Crispatotrochus, whose phylogenetic position remains uncertain. Methods and results The complete mitochondrial genomes of Crispa [...]

Chelarctus Holthuis, 2002 is widely distributed throughout the Indo-West Pacific, but its biogeographic patterns are unknown because Southern Hemisphere areas, such as the Coral Sea, remained poorly explored. Recent cruises organized by the Museum national d'Histoire naturelle of Paris and the Australian Institute of Marine Science allowed the molecular identification of Crenarctus crenatus (Whitelegge, 1900), Chelarctus aureus (Holthuis, 1963) a [...]

The present work reviews the deep-water cone fauna of New Caledonia and its Economic Exclusive Zone. It is based on the material collected for more than 40 years by oceanographic expeditions in the deep waters surrounding New Caledonia, organized by the Museum national d'histoire naturelle-Paris/ORSTOM, then Institut de Recherche pour le Developpement, in the framework of the Tropical Deep-Sea Benthos programme. A total of 2377 lots containing 51 [...]

Two new perchlet species (Perciformes: Serranidae), Chelidoperca pulchella [3 specimens, 58.8-70.4 mm standard length (SL)] and Chelidoperca pollux (3 specimens, 68.1-72.3 mm SL), are described from Okinawa Island, Ryukyu Islands, Japan and Nha Trang Bay, Vietnam, respectively. Both new species are morphologically similar to Chelidoperca flavimacula Psomadakis, Gon and Htut 2021, described from the northern Andaman Sea, but can be readily disting [...]

Once considered the most speciose mostly azooxanthellate scleractinian group, the family Caryophylliidae is found to be highly polyphyletic based on molecular data and is undergoing a process of systematic revision. High-throughput sequencing methods coupled with morphological analyses have facilitated revision of several scleractinian lineages, including the aforementioned family. In previous studies that relied on few mitochondrial and nuclear [...]

All species of Umboniinae known to occur in New Caledonia are discussed (19 species, 8 new, belonging to 10 genera, 2 new) and a key to genera is provided. An additional new species is described from the Bismarck Sea. Nine species are perhaps endemic to New Caledonia. The diversity of the fauna is comparable to that of Japan and Australia, both regions of much greater extent and spanning a much broader latitudinal range. Ethalia lampra (Watson, 1 [...]

Eight new species, including one new genus, Armaster chondros n. gen. sp., Atheraster luma n. sp., Atheraster phaeos n. sp., Atheraster umbo n. sp., Circeaster dux n. sp., Evoplosoma besseyae n. sp., Evoplosoma mystrion n. sp. and Evoplosoma pharos n. sp. are newly described from Australian waters. Atheraster, Circeaster and Evoplosoma have been reported previously as predators on deep-sea octocorals. Evoplosoma, Gilbertaster and Hippasteria are [...]
