Temporal dynamics of trace metals and arsenic in holopelagic Sargassum spp. during their retention in coastal waters

Tristan Gobert, Benjamin Châtelain, Solène Connan, Charlotte Renoul et autres

Since 2011, massive blooms of holopelagic Sargassum spp. have increasingly impacted tropical Atlantic and Caribbean coastlines, prompting research into biomass valorisation and the environmental risks associated with metal contamination. This study investigates the accumulation dynamics of trace elements—including total arsenic (As), inorganic …

Potential of Marine Sponge Metabolites against Prions: Bromotyrosine Derivatives, a Family of Interest

Maha Sinane, Colin Grunberger, Lucile Gentile, Céline Moriou et autres

The screening of 166 extracts from tropical marine organisms (invertebrates, macroalgae) and 3 cyclolipopeptides from microorganisms against yeast prions highlighted the potential of Verongiida sponges to prevent the propagation of prions. We isolated the known compounds purealidin Q (1), aplysamine-2 (2), pseudoceratinine …

Climate change and diminishing seasonality in Arctic benthic processes

Nathalie Morata, Emma Michaud, Marie-Aude Poullaouec, Jérémy Devesa et autres

The iconic picture of Arctic marine ecosystems shows an intense pulse of biological productivity around the spring bloom that is sustained while fresh organic matter (OM) is available, after which ecosystem activity declines to basal levels in autumn and winter. We investigated …
