How Do the Functional Resemblance Structure and Its Component‐Dependence Change Among the Successional Stages in Degraded Karst Forests?

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study was conducted in an extremely heterogeneous karst forest ecosystem. We found asynchronous changes in taxonomic and functional dissimilarities along the succession pathway and the functional redundancy dominated the functional resemblance structure.

Cladistic Relationships and Landscape Genetics of the Endangered Indian Peacock Softshell Turtle Nilssonia hurum (Gray, 1830): Implications for Strategic Conservation Planning

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study provides the first mitogenome of the endangered Peacock Softshell Turtle (Nilssonia hurum), revealing its evolutionary relationships and moderate genetic diversity across river basins. Species distribution modeling predicts up to 85% habitat loss under future climate scenarios, alongside severe declines in functional connectivity and rising ...

Modeling the Ages and Chemical Abundances of Elliptical Galaxies

The Astrophysical Journal
Spectroscopic studies of elliptical galaxies show that their stellar population ages, mean metallicity, and α enhancement traced by [Mg/Fe] all increase with galaxy stellar mass or velocity dispersion.

Investigation of Substructures of the Inner Halo Using the StarGO Algorithm with APOGEE DR17

The Astrophysical Journal
We applied the Stars’ Galactic Origin algorithm in 7D space (i.e., [Fe/H], [Mg/Fe], [Al/Fe], L _z ,  J _r ,  J _z ,  E ) to analyze stars in the inner halo with APOGEE DR17.

Characterization of Pilin A and Thioredoxin A Mutant Strains of Acinetobacter baumannii, From a Transposon Insertion Library, for Pili Production and Virulence‐Associated Properties

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Acinetobacter baumannii transposon insertion mutant strains ΔpilA and ΔtrxA display marked reductions of surface pili. The PilA (a major pilin protein) and TrxA (thioredoxin A) deficient bacteria also show attenuation in pathogenesis including the reduction of intestinal bacterial attachment, increased phagocytic uptake and decreased mortality from ...
