Challenges and opportunities in mitigating sarcoptic mange in wild South American camelids

The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
Wild South American camelids—vicuña and guanaco—face threats from sarcoptic mange, a contagious skin disease linked to severe population declines. Despite its impact, major gaps remain in understanding disease dynamics. This review summarizes current knowledge, identifies key data and management gaps, and outlines urgent actions for effective ...

Effects of salmon lice on numbers and size distributions of Atlantic salmon returning to spawn in Norwegian rivers

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
This study presents a quantitative relationship between infestations of post‐smolt recruits and size‐structured returns of mature salmon to Norwegian rivers, suggesting that louse infestation from farms may reduce returns of spawners and re‐structure the size distribution of mature river populations of Atlantic salmon.

Welfare Indicators for Aquaculture Research: Toolboxes for Five Farmed European Fish Species

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Refining approaches to measuring, monitoring and appraising animal welfare in aquaculture research is key to (i) protecting and optimizing it, (ii) documenting the severity of how and when it deviates, and (iii) ensuring good scientific quality, reliable results and reproducibility, amongst other factors.

Parasite spill-back from domestic hosts may induce an Allee effect in wildlife hosts [PDF]

, 2012
The exchange of native pathogens between wild and domesticated animals can lead to novel disease dynamics. A simple model reveals that the spill-back of native parasites\ud from domestic to wild hosts may cause a demographic Allee effect.
