In Situ Metabolic Rates of Alkane‐Degrading Sulphate‐Reducing Bacteria in Hydrocarbon Seep Sediments Revealed by Combining CARD‐FISH, NanoSIMS, and Mathematical Modelling

Environmental Microbiology, Volume 27, Issue 8, August 2025.
Sulphate‐reducing bacteria affiliated with clades SCA1, SCA2, and LCA2 were investigated using stable‐isotope incubations and in situ analysis at several hydrocarbon seep sites. Extrapolated rates of sulphate reduction and alkane degradation suggest that these clades play an important role at hydrocarbon seeps, contributing substantially to sulphur and

Toxicological analyses of the bone matrix: Successes and challenges

Archaeometry, Volume 67, Issue 4, Page 1001-1021, August 2025.
Abstract This study aimed to conduct an in‐depth and systematic literature review dealing with toxicological analyses on human bone tissue and focusing on the forensic toxicological and archaeotoxicological field. Several studies have focused their research on medical drugs, drugs of abuse, and trace elements on both human cadavers and skeletal remains,

Soil Respiration Responses to Prolonged Warming Vary Seasonally in a Subarctic Grassland

Global Change Biology, Volume 31, Issue 8, August 2025.
Warming has been suggested to critically affect soil carbon dynamics in northern ecosystems, but there are large uncertainties regarding the seasonality of warming effects on soil respiration, the main terrestrial source of atmospheric CO2. In our study, conducted in a subarctic grassland in Iceland, we found that decadal soil warming increased total ...

Symplastic and apoplastic pathways for local distribution of silicon in rice leaves

New Phytologist, Volume 247, Issue 3, Page 1280-1289, August 2025.
Summary Silicon (Si) is highly accumulated in both the leaf blade and sheath of rice, but the transporter mediating the local distribution of Si between these two tissues remains unidentified. We investigated the role of an aquaporin, OsLsi6, in the local distribution of Si in rice leaves.

Biogeochemical characterization of micritized carbonate grains in the shallow‐marine Al‐Kharrar Lagoon (Red Sea, Saudi Arabia)

Sedimentology, Volume 72, Issue 5, Page 1593-1619, August 2025.
ABSTRACT Micritization of marine carbonate grains is an early diagenetic process involving the alteration of the original carbonate fabric and the formation of cryptocrystalline textures through cycles of dissolution and reprecipitation. Microorganisms play a significant role in this process, actively contributing to the formation of constructive and ...
