Metal Bioaccumulation Patterns Revealed in Gulf of California Fish
Arsenic dominated metal accumulation in Gulf of California fish, yet its toxicity is likely dampened by the prevalence of organic forms. The study, covering species from distinct feeding guilds near La Paz and Santa Rosalía, links variability to diet and metabolic capacity. Essential metals like cobalt and manganese stayed near natural ranges, though seasonal runoff drove manganese peaks at Santa Rosalía. Selenium's high bioaccumulation signals potential trophic transfer. Location and species both shaped patterns, with historical mining influencing pollution indices.
Black Sea Seafood Nutrition: Tracking Nitrogen's Impact on Ocean Yields
The Black Sea's small pelagic fish and bivalves deliver essential protein and omega-3s, yet the nitrogen pathways that shape their nutritional value remain poorly quantified. This systematic review, following PRISMA 2020, finds a stark imbalance: ecosystem-level nitrogen dynamics are well documented, but direct biochemical data for key species like anchovy and Mediterranean mussel are scarce, with sprat nearly unstudied. Eutrophication-driven shifts may already be altering seafood quality. The gap between marine biogeochemistry and nutrition science demands integrated monitoring.
Ocean Warming Reshapes Zooplankton, Impacting Marine Ecosystems Worldwide
Zooplankton are not drifting passively through this crisis; they are being actively reshaped by it. Ocean warming, stratification, and acidification are filtering species by their traits, reorganizing communities in ways that ripple from grazing rates to carbon export. What stands out is the variability: jellyfish and krill respond differently, and those differences will strengthen some pathways while weakening others. Predicting the ocean's future demands integrating long-term observations with mechanistic models, and this review makes that urgency clear.
