Zoologica Scripta, Volume 55, Issue 5, Page 681-692, September 2026.ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract Distributed Acoustic Sensing (DAS) provides dense, wide‐aperture observations potentially ideal for imaging earthquake rupture processes. By combining data from a ∼450 km‐long seafloor DAS array offshore Chile and a conventional seismic network, we image an Mw 6.0 intermediate‐depth earthquake ∼400 km away in Argentina, achieving km‐scale ...

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract The Ecuadorian margin is a forearc‐arc system shaped by oceanic terrane accretion and Carnegie Ridge subduction, yet the accretion mechanism and ridge subduction extent remain poorly constrained. Using teleseismic P‐wave receiver functions from dense seismic arrays, we image velocity discontinuities within the overriding plate and subducting ...

Tectonic Tremor Reveals Slow Deformation Along the Antarctic–South American Subduction Zone
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract The Antarctic–South American subduction zone is among the least explored convergent margins and lacks documented large interplate earthquakes despite ongoing convergence. Here we report the discovery of tectonic tremor along this plate boundary using continuous seismic data.

I'll Be Dammed: Efficiency and Cost‐Analysis of a Rehabilitated Prehispanic Dam in the Andes
Geoarchaeology, Volume 41, Issue 4, July/August 2026.ABSTRACT Within archaeology there is a growing shift away from the purely aesthetic towards making the past relevant to present and future needs and demands. The Past Water Futures project charts the impact of ancient dam rehabilitation on climate change‐induced water scarcity in the North Central Andes.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract Uplifted Pleistocene marine terraces in the Illapel area along the forearc of central Chile record spatially and temporally variable uplift rates on glacial‐cycle timescales. However, the underlying mechanisms for this uplift variability and its potential relationship with the megathrust‐earthquake cycle remain poorly understood.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract This study investigates the nature of plume‐ridge interactions near a tectonic microplate using mantle Bouguer anomaly (MBA) gravity calculations. The focus of this investigation is a comparison of the Easter and Juan Fernandez microplates, which are located in the eastern Pacific Ocean along the Pacific, Nazca, and Antarctic plate boundaries.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.Abstract We investigate shear‐wave splitting of SKS and SKKS phases from teleseismic earthquakes to study the anisotropic structure of the lithosphere and upper mantle beneath the Colombian Andes. This area is shaped by complex interactions between the subducting Nazca and Caribbean plates beneath the South American plate. A recent broadband deployment

Controls on Valley‐Floor Width in the Western Andes
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.Abstract River‐valley floors are low relief, confined parts of the landscape that store sediment en route from mountains to lowlands. Transient sediment storage influences sediment budgets, biogeochemical cycles, and the preservation of environmental signals. The controls on valley‐floor width remain poorly understood, limiting the ability to reproduce

Two‐Layer Anisotropy Beneath Subduction Zones: Bayesian Inversion
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.Abstract Shear‐wave splitting measurements have the potential to constrain multiple layers of anisotropy and thereby enhance depth resolution. Using the formulation of Silver and Savage (1994, https://doi.org/10.1111/j.1365‐246x.1994.tb04027.x), previous studies have employed deterministic grid‐search approaches to identify best‐fitting two‐layer ...
