Protocol for integrative transcriptomic/metabolomic analysis: A case study on factors influencing the oyster-POMS disease

Deciphering the molecular mechanisms underlying complex biological interactions requires comprehensive approaches that capture these interactions across multiple regulatory and functional levels. Here, we present a protocol applied to the host-pathogen-environment interactions un...

Monitoring and assessment of elasmobranch bycatches in artisanal maritime fishing in southern Gabon, Central Africa

Elasmobranchs (sharks and rays) are particularly vulnerable to fishing pressure owing to their life-history traits, making them a major conservation concern in coastal ecosystems. To assess the composition and temporal dynamics of elasmobranch captures in southern Gabon, this stu...

Shipping noise may trigger valve closure responses in exploited scallop beds of the Gulf of St. Lawrence

Shipping noise is a pervasive form of underwater noise pollution, yet its effects on benthic invertebrates remain poorly integrated into spatial risk assessments. The Atlantic sea scallop (Placopecten magellanicus), a benthic bivalve supporting the world's largest wild pectinid f...

Valorization of Beach-Cast Biomass from the Invasive Seaweed Rugulopteryx okamurae on the Moroccan Coast: A Comparative Assessment of Extraction Conditions for Sodium Alginate Recovery

Rugulopteryx okamurae is an aggressively invasive seaweed whose proliferation along the Moroccan coastline represents both an ecological problem and an underexploited source of biomass. This work highlights the isolation of sodium alginate from R. okamurae under four combinations...

Multi-omics effect of contaminants exposure during embryogenesis on metamorphosis of blue mussel Mytilus edulis submitted to maritime traffic noise

Anthropogenic underwater noise is now considered one of the ‘emerging threats and ongoing challenges to biodiversity conservation’. Physiological changes have been observed in sessile invertebrates such as bivalves. Bivalve mollusks are of particular interest because of their sen...
