Structural framework and evolution of the Golfo San Jorge Basin: a synthesis

open access: yesLatin American Journal of Sedimentology and Basin Analysis
The Golfo San Jorge Basin evolved through a complex multiphase structural history from the Middle Jurassic to the Neogene. Its stratigraphic record captures key tectonic events in central extra-Andean Patagonia during Gondwana fragmentation and the ...

Compost legacy effects in active roadside restoration: Medium‐term shifts in plant succession

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Roadside restoration experiment established on volcanic tephra following road construction in Andean Patagonia. A single application of municipal (MC) or biosolids (BC) compost rapidly increased plant cover compared with untreated controls (C) but led to distinct, exotic‐dominated plant communities over 6 years.

Growth and reworking of freshwater microbially‐mediated carbonates in wind‐stressed lake margins (Lago Sarmiento, Southern Patagonia)

open access: yesSedimentology, Volume 73, Issue 3, Page 706-741, April 2026.
ABSTRACT Understanding the biotic and abiotic influences on the deposition and diagenesis of recent microbial carbonates is crucial for addressing the environmental and ecological significance of ancient organosedimentary structures. This study investigates these factors and their expression in the microstructure of Holocene tufa thrombolites from a ...

Urbanization and Seasonality Increase Introduced Plant Consumption by the World's Southernmost Parrot 城市化与季节性增加了全球最南端鹦鹉对引入植物的取食

open access: yesIntegrative Conservation, Volume 5, Issue 1, Page 86-103, March 2026.
Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...

Slab Gap‐Related Intraplate Magmatism as a Proxy of Maximum Flat Slab Extent in Patagonia

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Establishing the frontal extent of ancient flat subduction events from the geologic record can be challenging. This difficulty arises because magmatic activity in the arc typically ceases during complete slab flattening, and other meaningful proxies are usually absent. To address this issue, we examine early Paleocene intraplate magmatic units

Along the Silenced Footsteps of Latin American Pastoralists: From Mexico to Argentina, a Journey Through Pastoral Systems in Latin America

open access: yesThe Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 1, March 2026.
ABSTRACT Pastoralism worldwide faces a complex landscape of increased pressures and exclusion. Beyond ecological and economic challenges, pastoralists suffer eroding cultural identity, limited generational renewal, and political marginalization. Yet pastoral livelihoods are increasingly recognized as stewards of sustainable futures and amongst the best
