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...

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...

Grid4Earth: An Open-Source Python Ecosystem for Geospatial Data Integration Using an Ellipsoidal HEALPix DGGS

Abstract. The rapid growth in Earth observation (EO) and Digital Twin Earth data volumes creates a need for global, reproducible, and cloudnative spatial representations. Conventional latitude–longitude grids and projected tiling systems remain useful, but they introduce projecti...

Policy Consequentiality in Tourism Discrete Choice Experiments

Stated preference methods are widely applied in tourism research, yet their validity depends on respondents perceiving surveys as policy consequential. This paper examines how such perceptions shape willingness-to-pay (WTP) estimates for redesigned tourism supply. Using a discret...

Thermohaline gradients and frontal regimes in the northwestern Tropical Atlantic

Abstract. At the edge of the Amazon River plume, stirring by the North Brazil Current (NBC) and its eddies creates sharp surface thermohaline gradients on scales of O(1–100) km. This study provides a comprehensive picture of these gradients and fronts associated with the region's...

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...
