Seabird Prey in Space and Time: Combining Multiple Datasets to Model the Distribution of Sandeel (Ammodytes marinus) and Sprat (Sprattus sprattus) in the North Sea

Ecology and Evolution, Volume 16, Issue 11, November 2026.
Forage fish are key prey and commercial species in the North Sea ecosystem, but estimates of their biomass over detailed spatial and temporal scales is currently limited. To fill this vital research gap we employ Hierarchical Bayesian spatiotemporal models of sandeel (Ammodytes marinus) and sprat (Sprattus sprattus) in the North Sea, providing fine ...

UHPLC‐DAD‐HRMS2 Characterization of Novel Dihydrochalcone Conjugates From the Antiviral Mansoa hirsuta Extracts: Diagnostic Fragmentation Pathways and Dereplication of Oligomeric Polyphenols

Journal of Mass Spectrometry, Volume 61, Issue 11, November 2026.
ABSTRACT High‐resolution mass spectrometry (HRMS) coupled with ultra‐high‐performance liquid chromatography (UHPLC) enables rapid characterization of complex polyphenolic constituents in medicinal plants. Mansoa hirsuta (Bignoniaceae), a neotropical liana traditionally used to treat infectious diseases, remains poorly characterized chemically.

Systematic Optimization of an SLE‐DAPTAD LC–MS/MS Workflow for Simultaneous Quantification of Low‐Abundance Vitamin D3 Metabolites in Plasma

Rapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis of vitamin D3 metabolites is analytically challenging because these compounds are structurally similar, strongly matrix‐associated, and have poor ionization efficiency.
