Efecto del fuego sobre la estructura y densidad de leñosas del bosque de Prosopis caldenia (Burkart) en La Pampa, Argentina

Semiárida, 2023
La mayor parte del bosque de caldén (Prosopis caldenia) se encuentra en estado degradado producto del incremento de leñosas arbustivas y la reducción del estrato arbóreo.

Windblown Diatoms for Reconstructing Westerly Wind Variability in the South Atlantic Sector of the Southern Ocean

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Southern Hemisphere westerly winds are important drivers of Antarctic and sub‐Antarctic environmental change. Short observational wind records prevent us from fully understanding the scope of their variability. Proxy records provide valuable tools to extend environmental records. Here we present a novel wind study based on the use of windblown

Atmospheric Dust Transport to High‐Elevation Dronning Maud Land, Antarctica, Modulated by Cyclonic Circulation, the Pacific Decadal Oscillation, and Source Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract The dependence of aeolian dust transport on atmospheric circulation patterns allows dust preserved in Antarctic ice cores to serve as a proxy for past circulation variability. Here, we investigate dust transport to high‐elevation Dronning Maud Land (DML) in Antarctica through analysis of the 1300‐year‐old ISOL‐ICE ice core dust record together

Sobre "todos los fuegos el fuego"

Letras (Lima), 1968
Cada texto literario impone un modo específico de conocimiento, tanto porque es único e incomparable, como querían Croce, Vossler, Spitzer o los Alonso, quienes incluso exageraban el concepto de unicidad de la obra al no ver o minimizar las categorías genéricas que en ella se actualizan, cuanto, sobre todo, porque es única la relación lector-obra ...

Complex History of Organellar Introgression in Nothofagus Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Field photograph of an ancient Nothofagus tree covered with epiphytic lichens in the Patagonian temperate rainforest. This genus serves as a key model for investigating organellar introgression and evolutionary genomics in South America. ABSTRACT Hybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of ...

Entre los bordes. Hacia una nueva tipología de las series cortas

Ñawi: Arte, Diseño y Comunicación
Las series web, o series cortas, se caracterizan por su inestabilidad, incluso en su denominación. No son cine, tampoco TV. ¿Cómo podemos definirlas?

Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 1. Reconstruction of the Dynamics of the 11 September 1930 Event

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.

Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 2. Probabilistic Invasion Maps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract This study presents a new method to assess the hazard of deposit‐derived pyroclastic density currents (PDC), a critical threat on volcanic islands and on populated slopes of active volcanoes, considering the exemplary case study of Stromboli (Italy).

A 13,000‐Year Record of the Southern Hemisphere Westerlies Inferred From Pollen and Plant Wax Isotopes From the South Atlantic

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract We compare a new pollen record with pre‐existing plant‐wax isotope data from lacustrine sediments retrieved from Mt. Usborne, East Falkland. These records document variations in plant productivity, wind intensity, and moisture availability, to measure the influence of the Southern Hemisphere Westerlies (SHW) over the last 13,000 years.
