Sociability Under Anthropogenic Change: From Individual Behaviour to Population‐Level Consequences

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Our review synthesises empirical and theoretical research on how anthropogenic environmental change reshapes animal social behaviour from individuals to populations. We use sociability as an individual‐level lens, distinguishing context‐dependent expression from repeatable interindividual differences and linking both to social relationships, network ...

Genomic Investigation of Population Structure in a Secretive, Semi‐Fossorial Snake (Colubridae: Tropidoclonion lineatum) Across the Great Plains

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Here we provide the first examination of population structure and genetic variation within a secretive semi‐fossorial snake (Tropidoclonion lineatum), widely distributed across the Great Plains. In our evaluation, we assess the validity of the four historically described subspecies and identify a new potentially isolated population. Our findings reveal

Characteristics of Microbiota in Different Segments of the Digestive Tract of Orange‐Collared Keelback (Rhabdophis himalayanus)

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Using shotgun metagenomic sequencing and untargeted metabolomics, we characterized the microbial communities and metabolic profiles across the stomach, small intestine, and large intestine of Rhabdophis himalayanus. Although overall microbial diversity was similar among digestive tract segments, distinct taxonomic, functional, and metabolic differences

Flavonoids as Modulators of Lipid Mediator Signaling: A Narrative Review on Mechanisms, Current Evidence, and Gaps in the Literature

Molecular Nutrition &Food Research, Volume 70, Issue 20, 28 October 2026.
Flavonoid consumption may modulate phospholipase activity and COX‐, LOX‐, and CYP450‐dependent oxylipin biosynthesis, reshaping lipid mediator networks. Emerging evidence suggests these shifts may favor inflammatory resolution over propagation, with implications for metabolic, cardiovascular, and neuroinflammatory disease risk.
