Reconstructing Late Pleistocene to Prehistorical Holocene Geomagnetic Field Variations From La Palma Lava Flows (Canary Islands, Spain): Unraveling Viscous Components

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract We present new vector paleomagnetic data from 13 radiometrically dated lava‐flows in southern La Palma (Canary Islands) spanning from 1 to 56 ka, which covers most of the Late Pleistocene to prehistoric Holocene volcanic record in the island.

Imaging of Magma Intrusion Below La Palma During a Strong Effusive Eruption in 2021 Inferred From Repeated Seismic Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The 2021 eruption of Cumbre Vieja on La Palma, Canary Islands, provided a unique opportunity to investigate the dynamics of magma migration and storage during a large effusive eruption. In this study, we employ repeated seismic tomography to image temporal changes in the subsurface structure beneath La Palma, using body‐wave travel times from ...

Understanding the Risks Associated With Recirculating Aquaculture Systems: Identification of Enterococcus Species, Persistence, and Antimicrobial Resistance Phenotypes

Aquaculture Research, Volume 2026, Issue 1, 2026.
Enterococci are considered indicators of fecal contamination from mammals and birds and of antimicrobial resistance (AMR) from the environment. This longitudinal observational study assessed the persistence of Enterococcus spp. in a recirculating aquaculture system (RAS), determined AMR phenotypes and compared them with isolates recovered from human ...

Volcanic soils alleviate the allelopathic capacity of Empetrum nigrum in degraded tundra ecosystems

Oikos, Volume 2025, Issue 10, October 2025.
Land degradation due to unsustainable land use is of major concern worldwide and recovery is often slow. A potential mechanism behind slow recovery of degraded ecosystems is the retarding impacts of allelopathic plant species on the establishment of species that might facilitate the recovery process.
