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 ...

Precipitation and Temperature‐Dependent Locomotor Performance Drive the Abundance of a Neotropical Lizard

Biotropica, Volume 57, Issue 6, November 2025.
We investigated how climate and ecophysiology affect the demography of the lizard Tropidurus oreadicus in the Brazilian Cerrado. While lizards were more frequently captured in the dry season, their abundance peaked during the rainy season when their locomotor performance was highest.

Mapping Resilient Landscapes to Climate Change in a Megadiverse Country

Global Change Biology, Volume 31, Issue 10, October 2025.
Our mapping of terrestrial climate‐resilient sites for biodiversity across Brazil identifies sites with greater chances of providing suitable conditions for species to persist under regional climate change. Landscape resilience information has the potential to be used to effectively guide decision‐making and public policy on strategies for conservation,

Microquasar models for 3EG J1828+0142 and 3EG J1735-1500 [PDF]

, 2004
Microquasars are promising candidates to emit high-energy gamma-rays. Moreover, statistical studies show that variable EGRET sources at low galactic latitudes could be associated with the inner spiral arms.
