An Improved Chemical Extraction Procedure for the Sr Isotope Analysis of Liquid Agrifood Samples Applied to Authenticating the Origin of Maple Syrups in Quebec (Canada)

Rapid Communications in Mass Spectrometry, Volume 39, Issue 16, 30 August 2025.
ABSTRACT Rationale We describe a new simplified sample preparation technique, based on dual chromatography for the analysis of 87Sr/86Sr in liquid agri‐food samples. We applied this approach for authenticating the origin of maple syrup products in Quebec, characterizing the 87Sr/86Sr of soil profiles from geologically distinct maple groves, including ...

DNA Metabarcoding Focusing on Eukaryote Communities on Langhovde Glacier, East Antarctica

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Based on comprehensive 18S rRNA gene analysis, this study characterises the eukaryotic communities inhabiting the supraglacial environments of Langhovde Glacier, East Antarctica, in relation to the associated aquatic chemistry. Genetic differences between organisms found in the surrounding ice‐free areas and those in distant snow and ice fields are ...

The Distribution of Major and Trace Elements Across a Garnet Population From the Kalak Nappe Complex (Finnmark, Scandinavian Caledonides): Evidence for Size‐Dependent Growth and Compositional Equilibration in the Garnet Zone

Journal of Metamorphic Geology, Volume 43, Issue 6, Page 613-640, August 2025.
ABSTRACT A garnet population from the lower Kalak Nappe Complex in Finnmark (Arctic Norway) was characterized using high‐resolution X‐ray micro‐computed tomography, electron probe micro‐analysis and laser ablation inductively coupled plasma mass spectrometry mapping to assess the extent of compositional equilibration and the controlling crystallization
