Microeukaryotic Diversity and Habitat Structuring in a Desiccating Alkaline Maar Lake (Central Mexico)

Journal of Eukaryotic Microbiology, Volume 73, Issue 6, November/December 2026.
ABSTRACT Microeukaryotes are important components of microbial food webs in saline and alkaline lakes, yet their diversity and distribution across distinct microhabitats remain poorly understood. We characterized microeukaryotic communities associated with microbialites, microbial mats, hypersaline waters, and sediments in the desiccating maar lake ...

Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

Journal of Anatomy, Volume 249, Issue 5, Page 1181-1207, November 2026.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...

Seasonal Variations of the Martian Middle‐Atmosphere CO2/Ar Ratio Inferred From MAVEN/NGIMS Observations

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The carbon dioxide (CO2)/argon (Ar) ratio is a useful tracer of atmospheric circulation on Mars, but it remains observationally poorly constrained in the middle atmosphere, where large‐scale circulation occurs. In this study, we infer the CO2/Ar ratio at the homopause, which marks the upper boundary of the well‐mixed Martian middle atmosphere,

A Radio Science Experiment for Dragonfly to Investigate Titan's Rotation and Interior Structure

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract NASA's mission Dragonfly to Titan is scheduled for launch in 2028 with arrival in 2034 to study Titan's prebiotic chemistry and habitability. We propose a radio science experiment for Dragonfly, in which radiometric tracking of the rotorcraft from the Deep Space Network, already baselined for communications and navigation, is used as a ...
