Raman Study of the Slobodka Ordinary Chondrite

open access: yesJournal of Raman Spectroscopy, EarlyView.
The texture and mineral chemistry of Slobodka are most consistent with L4 chondrites, exhibiting strong shock metamorphism characteristic of shock stage S4, including irregular and planar fractures, undulatory extinction, and mosaicism in olivine, pyroxene, and plagioclase.

Study of Garnets in Hellenistic–Roman Jewellery From the Collections of the Archaeological Museum of Thessaloniki, Greece

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study presents the gemological analysis of 25 garnets from Hellenistic and Roman jewellery in the Archaeological Museum of Thessaloniki using mobile Raman spectroscopy and micro‐EDXRF. The garnets are classified into three geochemical clusters, with notable differences in distribution between Thessaloniki and Pydna, suggesting distinct trading ...

The Pace di Siena and its Gems

open access: yesJournal of Raman Spectroscopy, EarlyView.
For the first time, the gems of the Pace di Siena, a rare en ronde bosse enamel preserved in Arezzo (Italy), have been analyzed using a transdisciplinary approach. The combination of gemmology and Raman spectroscopy has led to the identification of blue sapphires and pink spinels, contradicting previous historical classifications.

The role of light quality and species richness in shaping phytoplankton communities

open access: yesLimnology and Oceanography, EarlyView.
Abstract In natural water bodies, the light spectrum changes with depth, often toward a higher proportion of blue light. While spectral niche partitioning and functional redundancy are important concepts, our understanding of how light spectrum changes affect phytoplankton communities is limited.

Impact of glacial cycles and ocean currents on radiation events in the Japanese turban snail Lunella coreensis

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract The Japanese turban snail Lunella coreensis is sensitive to ocean currents due to its short pelagic larval stage and moderate dispersal ability, making it an ideal model for studying genetic diversity shaped by paleoclimatic shifts. In this study, we analyzed the mitochondrial genes COI and 12S of museum samples collected from various coasts ...

Culturing the solitary ascidian Phallusia nigra in closed and open water systems for tropical environmental research

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Marine and coastal ecosystems have been undergoing dramatic shifts due to global environmental changes. The rise in seawater temperature, ocean acidification, hypoxia, eutrophication, and anthropogenic pollution severely affects marine organisms.
