On traits matching and the modular organization of food web and occurrence networks

open access: yesJournal of Animal Ecology, Volume 95, Issue 5, Page 837-850, May 2026.
What mechanisms shape ecological networks? In Paraná River piscivores, species traits and abundance scaling promote modular structures. Our findings reveal how communities self‐organize and highlight the conditions needed to sustain them. Abstract Modularity and nestedness have been observed recurrently across different ecological networks, including ...

Modulatory Effects of Cirsimarin on Lung Cancer A549 Cells Migration in 2D and 3D Cultures Involves Transcriptional Regulation of Metalloproteinases

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 3, March 2026.
In 2D culture, the cirsimarin (i) decreased cell viability in both assays, (ii) induced apoptosis, (iii) reduced clonogenicity, (iv) prevented cell migration, (v) induced DNA damage, and (vi) negatively modulated gene expression. In the 3D model, reductions in spheroid viability, area, and cell migration were also observed.

From Local Biodiversity to Global Food Security: Antioxidant Evidence of Unconventional Edible Plants (2020–2025)

open access: yesJournal of Food Process Engineering, Volume 49, Issue 2, February 2026.
This scoping review (2020–2025) compiles validated evidence on the antioxidant potential of unconventional edible plants (PANCs). Thirty species showed high phenolic content and strong radical‐scavenging activity, reinforcing their role as natural antioxidants and sustainable alternatives to synthetic additives within biodiversity‐based food systems ...
