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

Journal 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

Ecology 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

Journal 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 ...
