Estudios sociales y socioecológicos sobre restauración ecológica: Una revisión de la literatura a escala global e iberoamericana

open access: yesEcología Austral, 2020
La restauración ecológica (RE) se ha consolidado como campo académico y política pública. No obstante, podría presentar sesgos que obstaculicen el abordaje integral de sus causas y consecuencias naturales y sociales.

Harnessing the benefits of herbarium specimen digitisation for inferring recent and ongoing plant extinctions

open access: yesNew Phytologist, Volume 251, Issue 2, Page 677-688, July 2026.
Summary Evidence for the ongoing biodiversity crisis rests on assessment of a small fraction of described species, with major knowledge gaps for most organisms, including plants. Here, we highlight how digitised herbarium specimens can be used to accelerate and improve estimates of recent and ongoing plant extinctions.

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

open access: yesGeophysical 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

open access: yesJournal 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

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

open access: yesEcology 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 ...

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

open access: yesPaleoceanography 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.
