Landscape of exposure: Metapopulation dynamics and local environment structure pathogen exposure in desert bighorn sheep

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Dynamics of infectious disease in natural populations result from processes across scales, from host characteristics shaping exposure risk and susceptibility, to local environmental conditions driving vector populations, to the structure of metapopulation networks shaping transmission of pathogens across the landscape.

A Focus on Natural Autophagy Modulators as Potential Host‐Directed Weapons Against Emerging and Re‐Emerging Viruses

open access: yesMedicinal Research Reviews, Volume 45, Issue 6, Page 1850-1882, November 2025.
ABSTRACT Autophagy is a highly conserved intracellular process involved in maintaining homeostasis and in the degradation of damaged organelles and external pathogens. Nature provides complex and varied reservoirs of scaffolds and chemical entities that may have a pivotal role in the search for new therapeutic leads.
