Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

open access: yesJournal of Animal Ecology, Volume 95, Issue 9, Page 1629-1641, September 2026.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Proline‐Derived N‐Heterocyclic Carbene Gold(I) Complexes With Dual DNA Binding and Thioredoxin Reductase Inhibition

open access: yesChemMedChem, Volume 21, Issue 16, 27 August 2026.
Proline‐derived Au(I)–NHC complexes display potent anticancer activity against lung and triple‐negative breast cancer cells. The cationic complexes promote DNA intercalation, thioredoxin reductase inhibition, ROS overproduction, and mitochondrial membrane depolarization, ultimately triggering apoptotic cell death through a multimodal mechanism of ...
