The Role of Nurse Trees in the Plant Community of Park Grassland: A Case Study in Southern Brazil

Applied Vegetation Science, Volume 28, Issue 2, April/June 2025.
Tree species facilitate the assembly of park grassland plant communities by altering environmental conditions and promoting woody and herbaceous species under their canopies. They support biodiversity and have potential for ecological restoration but may contribute to woody nucleation.

A 300 kyr record of past hydroclimate change from alluvial fans in the southern Central Andes

Earth Surface Processes and Landforms, Volume 50, Issue 1, January 2025.
We dated alluvial‐fan deposits at the Sierra de Aconquija in northwestern Argentina. The alluvial fans aggraded and incised in phase with known hydroclimate changes throughout the last ~300 kyr. Abstract Alluvial fans are hypothesised to record signals of past hydroclimate changes in their depositional chronologies and slopes.

Continuities and ruptures in Argentine's regional discourse: The process of conceptual construction of the Pampa Continuidades y rupturas en el discurso regional argentino: El proceso de construcción conceptual de la Pampa

Mundo Agrario, 2012
The present article aims to compare the main proposals of regionalization of the argentine territory seeking to establish -from its survey, analysis and comparison- continuities and ruptures around the conceptual construction of the Pampa.

Creep on the Argentine Precordillera Décollement Following the 2015 Illapel, Chile, Earthquake: Implications for Andean Seismotectonics

Geophysical Research Letters, Volume 51, Issue 19, 16 October 2024.
Abstract The Central and South‐Central Andes form a “two‐sided” mountain belt bounded by distinct zones of convergence in the forearc and backarc flanks. Previous geodetic interseismic deformation studies found that the forearc to backarc velocity field is better explained when elastic models allow reverse aseismic slip on the Andes eastern‐flank ...

Structural Inheritance in the Eastern Cordillera, NW Argentina: Low‐Temperature Thermochronology of the Cianzo Basin

Tectonics, Volume 43, Issue 6, June 2024.
Abstract The present‐day deformation style of the Eastern Cordillera in NW Argentina is strongly influenced by the inversion of pre‐existing Paleozoic and Mesozoic structures. In particular, the extensional faults and lithological contrasts resulting from the Cretaceous–Paleogene Salta Rift phase form heterogeneities that were preferentially ...

Kinematic Evolution of the Santa Bárbara System in the Foreland of the Central Andes of Northwestern Argentina (26°S)

Tectonics, Volume 43, Issue 6, June 2024.
Abstract Compared to the thin‐skinned Subandean foreland fold‐and‐thrust belt of northern Argentina and Bolivia, the tectonically active morphotectonic province of the Santa Bárbara System in the Andean broken foreland of northwestern Argentina is characterized by a temporally and spatially disparate deformation style. Although there is no well‐defined

Sedimentation tempo in an Early Jurassic erg system: Refined chronostratigraphy and provenance of the Clarens Formation of southern Africa

Basin Research, Volume 36, Issue 3, May–June 2024.
Maximum depositional ages of the Early Jurassic Clarens Formation of southern Africa. Abstract The Clarens Formation is a widespread aeolianite deposited over southern Gondwana and represents the final phase of erg evolution in the main Karoo Basin during the Early Jurassic.

Implications of Flat‐Slab Subduction on Hydration, Slab Seismicity, and Arc Volcanism in the Pampean Region of Chile and Argentina

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 3, March 2024.
Abstract The Pampean flat slab in central Chile and Argentina is characterized by the inland migration and subsequent cessation of arc volcanism since the mid‐Miocene. Slab flattening also affects the distribution and number of intermediate‐depth earthquakes and the evolution of the overlying continental thermal structure.

Late Holocene Dust Deposition Fluxes Over the Entire South Atlantic Ocean

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 1, January 2024.
Abstract Mineral dust accumulated on the ocean floor is an important archive for reconstructing past atmospheric circulation changes and climatological conditions in the source areas. Dust emitted from Southern Hemisphere dust sources is widely deposited over the oceans. However, there are few records of dust deposition over the open ocean, and a large
