Aeolian Dust Provenance in Central East Antarctica During the Holocene: Environmental Constraints From Single‐Grain Raman Spectroscopy

open access: yesGeophysical Research Letters, 2019
We analyzed the single‐grain mineralogical composition of aeolian dust transported to central East Antarctica for provenance purposes. Comparison with data from the last glacial period shows for the first time disappearance of carbonates during the ...

Carbon dynamics in high‐Andean tropical cushion peatlands: A review of geographic patterns and potential drivers

open access: yesEcological Monographs, Volume 94, Issue 3, August 2024.
Abstract Peatlands store large amounts of carbon (C), a function potentially threatened by climate change. Peatlands composed of vascular cushion plants are widespread in the northern and central high Andes (páramo, wet and dry puna), but their C dynamics are hardly known.

Ancestry and genetic structure of resident and anadromous rainbow trout (Oncorhynchus mykiss) in Argentina

open access: yesJournal of Fish Biology, Volume 104, Issue 6, Page 1972-1989, June 2024.
Abstract Since the first introduction from North America more than a century ago, rainbow trout (Oncorhynchus mykiss) have rapidly established self‐sustaining populations in major river basins of Patagonia. Many generations later, only the freshwater resident life history is expressed in the Chubut and Negro rivers of northern Argentinian Patagonia ...

Km‐Scale Simulations of Mesoscale Convective Systems Over South America—A Feature Tracker Intercomparison

open access: yesJournal of Geophysical Research: Atmospheres, Volume 129, Issue 8, 28 April 2024.
Abstract Mesoscale convective systems (MCSs) are clusters of thunderstorms that are important in Earth's water and energy cycle. Additionally, they are responsible for extreme events such as large hail, strong winds, and extreme precipitation. Automated object‐based analyses that track MCSs have become popular since they allow us to identify and follow

Reconstruction of the pelvic girdle and hindlimb musculature of the early tetanurans Piatnitzkysauridae (Theropoda, Megalosauroidea)

open access: yesJournal of Anatomy, Volume 244, Issue 4, Page 557-593, April 2024.
Piatnitzkysauridae were Jurassic theropods that represented one of the earliest lineages to have evolved moderate body size. Here, we reconstructed the hindlimb musculature of this clade, allowing a more complete understanding of myological evolution in theropod pelvic appendages. Abstract Piatnitzkysauridae were Jurassic theropods that represented the

Partial migration in Magellanic penguins

open access: yesJournal of Avian Biology, Volume 2024, Issue 3-4, March/April 2024.
We studied the migration of Magellanic penguins near the southern tip of the breeding distribution, and for the first time found evidence of partial migration for this species within the same colony. Forty‐three percent of the penguins studied stayed within ~ 290 km of the colony (residents), while others went northwards as far as 2000 km. All penguins

Tectonostratigraphic significance of the Neogene sedimentary record of northwestern Austral-Magallanes Basin, Argentinean Patagonia

open access: yesLatin American Journal of Sedimentology and Basin Analysis, 2021
Despite their geodynamic significance, the stratigraphy and paleoenvironments of the lower-middle Miocene clastic deposits, genetically related to subduction-driven lithospheric processes at the latitude of the Chile Triple Junction are poorly known ...
