Case Study: A Dexamethasone Suppression Test in Koalas (Phascolarctos cinereus)

open access: yesVeterinary Medicine and Science, Volume 12, Issue 1, January 2026.
With a dexamethasone suppression test, we aimed at determining the ability of the feedback loop to decrease the concentration of plasma cortisol in koalas. No cortisol suppression was observed, rather an increase in plasma cortisol concentration in all koalas. This was also reflected in the increase of cortisol metabolites in faeces.

Acoustic Observations Unveil Seasonal Fluctuations and Regulation of Zooplankton Biomass and Its Vertical Distribution at a Mid‐Latitude Long‐Term Ocean Observatory

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract Zooplanktonic organisms are considered a key link between different trophic levels. The ecosystem structure and dynamics are affected by changes in their population and phenology. In this work, the causes and timing of changes within the seasonal cycle of zooplankton biomass vertical distribution in oceanic waters of the Bay of Biscay were ...

Characterization of a Lava Plain NW of Ascraeus Mons, Mars, Through Surface Morphometric Analyses and SHARAD Subsurface Detections

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract The Martian lava plains are characterized by their extensive, low‐relief surfaces, which are the result of numerous basaltic eruptions and feature a variety of volcanic landforms, including vents, cones, pits, and skylights. The combination of these features and impact craters yields a significant understanding of the planet's geological past ...

A branching process approach to lifetime reproductive success of structured populations: Variance–covariance and distribution

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 1, Page 137-157, January 2026.
Abstract Lifetime reproductive success (LRS) is a key metric in ecology and evolution. It measures the number of offspring produced by an individual during its lifetime. In epidemiology, it corresponds to the number of secondary cases generated by an infected individual.
