How many cows are in the desert? Molecular phylogeny and species delimitation of the genus Gyriosomus (Coleoptera: Tenebrionidae: Pimeliinae) from the Atacama Desert

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
The newly systematic rearrangement of Gyriosomus recognizes 9 clades, validates 21 taxonomical species and suggests 12 synonyms and 12 species candidates. Three taxonomical species were not evaluated. Polymorphisms, convergences and crypsis have been detected, and therefore morphology‐based taxonomy should be approached with caution. Ecological drivers

Integrated Magnetic and Energy Storage Properties of Nickel Cobaltite/Graphene/Iron Oxide Hybrid Nanomaterials

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Hybrid nanostructures combining metal oxides with carbon‐based materials offer significant promise for multifunctional applications such as energy storage and magnetism. In this study, a magnetic ternary nanocomposite consisting of NiCo2O4/Fe3O4/rGO was synthesized via a modified chemical oxidation method for supercapacitor applications.

Revisiting the taxonomy and nomenclature of Phyla, a small genus of Verbenaceae

Nordic Journal of Botany, Volume 2025, Issue 12, December 2025.
Phyla is unique within Verbenaceae due to the presence of malpighiaceous hairs. Its taxonomy has long been marked by difficulties in defining species boundaries. The most recent revision of the genus recognized five species and three varieties. In this study, however, we recognize only two species and no varieties: P.

Fault‐Induced Hydration and Serpentinization of the Incoming Lithosphere Enhances Intra‐Slab Seismicity Offshore Taltal (∼25°S), Northern Chile

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The northern Chilean margin is one of the most seismically active subduction zones, with a high potential for future megathrust earthquakes. The tectonic structure and the state of hydration of the incoming Nazca Plate, and their control on seismogenesis are poorly known, as the offshore domain remains largely unexplored. Here, we present high‐
