Rapid isotopic exchange in mineralogically unaltered coral skeletons
Published 2025-07-01“…Simulated diagenesis experiments using modern coral skeletons immersed in 18O-enriched artificial seawater revealed that microstructural complexity – specifically, the phylogenetically controlled arrangement of rapid accretion and thickening deposits – strongly influences isotopic exchange. Organic-rich regions within the skeleton facilitate water penetration, leading to heterogeneous isotopic alteration correlated with skeletal architecture. …”

Methylmercury carbon isotope fractionation during biotic methylation by the bacterial BerOc1 strain
Published 2025-07-01“…The maximum methylation yield observed in our samples was around 15% of the available iHg and a constant C isotope fractionation was detected over time. We propose that the methyl group is metabolically transferred from the carbon sources to cobalamin in the HgcA protein and subsequently to inorganic mercury (iHg), leading to consistent light C isotope enriched CH3Hg signatures.…”

Spatiotemporal variability in the feeding habits of anchovy and sardine: a comparison of upwelling and river-runoff driven ecosystems
Published 2025-08-01“…Moreover, the greater number of cases showing wider isotopic niches and higher isotopic overlap between species—and between life stages—in the Tyrrhenian Sea than in the Strait of Sicily suggests higher variability in feeding behaviour and access to more diversified food sources. …”

First evidence of bronze production in the Iron Age I southern Levant: A direct link to the Arabah copper polity.
Published 2025-01-01“…Microstructural features indicate that primary alloying of copper and tin-rather than the re-melting of scrap-was practiced at the site. Lead isotope analysis, chemical composition, and microstructure link some of the metal specifically to the Faynan ores, and other finds to the Timna ores, suggesting that both ores, possibly controlled by a joint polity, supplied copper to el-Ahwat. …”
