Drivers of plant phenolic concentration across global drylands

open access: yesJournal of Ecology, Volume 114, Issue 1, January 2026.
This study advances the understanding of how biotic and abiotic stressors shape plant defence strategies in global drylands. The findings shed novel insights about how plant secondary metabolites and their associated functions shift in response to changes in climate and grazing pressure, two key global change drivers with significant implications for ...

Gut Microbiota Differences in Down Syndrome Are Most Pronounced in Childhood and Diminish With Age

open access: yesInternational Journal of Microbiology, Volume 2026, Issue 1, 2026.
Introduction Down syndrome (DS) is linked to increased risks of metabolic, gastrointestinal, and neurodegenerative disorders. Early alterations in the gut microbiota have potential long‐term health impacts. This report appears to be the first study to stratify DS participants by age to explore early‐life microbiota changes.

Microcanonical Rate Constants With Rice–Ramsperger–Kassel–Marcus in Eyringpy

open access: yesJournal of Computational Chemistry, Volume 46, Issue 30, 15 November 2025.
The new implementation of the Rice‐Ramsperger‐Kassel‐Marcus theory in Eyringpy accurately calculates both the density of states (DOS) for reactants and transition states, as well as the microcanonical rate constants kE$$ k(E) $$ for unimolecular chemical reactions, incorporating tunneling corrections using the Eckart model.

Plant Trait Matching Occurs in Facilitative Interactions Across Global Drylands

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 11, November 2025.
ABSTRACT Aim Plant functional traits can influence interaction outcomes between nurse and target plants through a “functional trait match”, which occurs when the traits of nurse plants ameliorate their environment, and target plants possess traits that allow them to benefit from this ameliorated environment.
