Triplet Acetone Generation by Pseudoperoxidase Activity of Myoglobin: Structural Damage and Quenching

Luminescence, Volume 41, Issue 9, September 2026.
Ferrimyoglobin pseudoperoxidase activity was demonstrated during isobutyraldehyde oxidation, yielding electronically excited triplet acetone and inducing structural damage. Sorbates and 9,10‐dibromoanthracene‐2‐sulfonate exhibited protective effects.

Sedimentology and geochemistry of the recent sediments of the river system on Hurd Peninsula, Livingston Island, Antarctica

The Depositional Record, Volume 12, Issue 4, September 2026.
This study investigates the sedimentology and geochemistry of recent sediments from ephemeral river systems on Hurd Peninsula, Livingston Island, Antarctica. These systems are important for understanding sedimentary and geochemical processes in unique polar environments.

Microfabric controls on the preservation and erosion of Late Pleistocene freshwater microbialites in northwestern Patagonia, Argentina

The Depositional Record, Volume 12, Issue 4, September 2026.
Microfabric distribution controls porosity, preservation and erosion in Late Pleistocene microbialites from the Maquinchao Basin (Argentina). Differential preservation of laminated and shrub fabrics shapes the present morphology of the carbonate build‐ups and influences their palaeoenvironmental interpretation.

Mitogenomic and Ecological Perspectives on the Wide‐Ridged Indo‐Pacific Finless Porpoise Neophocaena phocaenoides: Toward Emerging Conservation Strategies

Ecology and Evolution, Volume 16, Issue 9, September 2026.
IUCN‐defined extant distribution of the Indo‐Pacific finless porpoise (Neophocaena phocaenoides), overlaid with occurrence records, global Marine Protected Areas (MPAs), and Important Marine Mammal Areas (IMMAs). ABSTRACT Prior to this study, the narrow‐ridged finless porpoise (Neophocaena asiaeorientalis) had been extensively studied across East Asia,

Genetic (Genomic) and Morphological Evidence Suggest That the Korean Endemic Fat Minnow (Rhynchocypris kumgangensis) and the Deogyu Population Represent Distinct Species

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Clear genetic and morphological divergence were revealed between the two Korean endemic 'putative' species Rhynchocypris kumgangensis and the Deogyu population (R. deogyuensis) using an integrated analysis of molecular markers, mitogenomes, and geometric and morphometrics on body shape.
