Mechanisms of the QBO Influence on the Tropical Troposphere: Modulation by ENSO Conditions

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) is the dominant mode of tropical stratospheric variability that can influence tropospheric circulation and convection. El Niño‐Southern Oscillation (ENSO), which is the primary source of interannual variability in the tropical troposphere, can modulate both the QBO and its impact on the tropical troposphere.

Nectar Robbery by Native and Invasive Bumblebees Reduces Floral Rewards but Not Seed Production in Desfontainia fulgens

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
We evaluated nectar robbery by native and invasive bumblebees in the hummingbird‐pollinated shrub Desfontainia fulgens in southern Chile. Nectar robbery strongly reduced nectar standing crop and altered floral visitation patterns, but these proximate effects did not translate into reduced seed production under natural pollination conditions.

Contrasting CO2‐response strategies in Pardina lentils: Yield maximization in a commercial cultivar and seed composition adjustment in a landrace

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 9, Page 5422-5436, July 2026.
Abstract BACKGROUND Assessing crop's responses to elevated carbon dioxide (eCO2) is crucial for global food security. This study examines the impact of eCO2 (700 μmol mol−1) on the cultivars of lentil (Lens culinaris), local Pardina Verde Rayada lentil (PVRL), and commercial Pardina lentil (PL) in terms of the productivity and nutritional composition ...

Vulnerability to Global Environmental Change? Isotopic Inference of a Resident Population of Common Bottlenose Dolphins, Tursiops truncatus, in a Coastal Lagoon in the Southern Gulf of Mexico

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Through the isotopic composition of 211 samples of six different tissues (muscle, liver, heart, kidney, spleen, and lung) obtained from 51 Tursiops truncatus strandings over nearly a decade (2013–2022), this study evaluated the impact of environmental variations on a resident population in a coastal lagoon in the southern Gulf of Mexico ...

Tierra firme

open access: yes, 2019
Una mujer ingresa en el espacio escénico. Camina lento hacia el centro portando, cual Medusa, una serie de cabezas. Pronto el público descubre que esas cabezas pertenecen a otros cuerpos que ella sostiene y que, a partir de una sucesión de empujes y de impulsos, empiezan a «volar» por el aire, rebotando sobre su cuerpo, viajando de un hombro a una ...

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

Pedro Tierra

open access: yesRemate de Males
Pedro Tierra transformou a luta política contra a Ditadura Militar e as consequentes torturas sofridas em necessidades para a poesia que, por sua vez, com ele, estendia o combate em sua dimensão simbólica. Nele, como em outros poetas que foram presos políticos, a articulação entre poesia e vida se coloca mais do que necessária.
