Cosmic Ray Counting Variability From Water‐Cherenkov Detectors as a Proxy of Stratospheric Conditions in Antarctica

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract This work examines atmospheric effects on cosmic ray counts observed by a Water‐Cherenkov detector at the Argentine Antarctic Marambio Station. We analyze the influence of ground‐level barometric pressure and geopotential height at various pressure levels on daily particle rates, finding the strongest association at 100 hPa, linked to ...

When African and European Lineages Meet: The Genetic Landscape of Honey Bees in Argentina

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Using a 272‐SNP panel, we explored how Africanized (AHB) and European (EHB) honeybee populations interact across Argentina's diverse landscapes. A clear latitudinal pattern in Africanization, with an interesting inverse relationship between African (A) and European (C) ancestry.

Culturable bacteria associated with Anastrepha fraterculus sp. 1: in search of nitrogen‐fixing symbionts with biotechnological potential

Insect Science, Volume 32, Issue 5, Page 1621-1640, October 2025.
Anastrepha fraterculus, a major fruit fly pest in South America, benefits from gut bacteria for nutrient assimilation and nitrogen fixation. This study examined culturable gut bacteria in A. fraterculus males from wild, lab‐reared, and lab‐colony groups, focusing on diazotrophs.
