Journal of Fish Biology, Volume 107, Issue 4, Page 1323-1334, October 2025.Abstract A natural parasitic infection with the external ciliate protozoan, Chilodonella hexasticha, was recorded 3 days post‐transportation (PT) in the gills and skin of African catfish (Clarias gariepinus). Infected fish displayed behavioural changes and typical signs of infection.

Postglacial Echoes: Parasite Genomics Uncover Environmental Changes in Postglacial European Lakes
Molecular Ecology, Volume 34, Issue 17, September 2025.ABSTRACT Postglacial environmental changes have influenced biodiversity and species evolution, yet the genomic and demographic responses of parasites remain underexplored. This study investigates the population genetics and demographic history of the flatworm Phyllodistomum umblae, a generalist trematode at the definitive host level infecting Coregonus

Antagonistic Rewiring and Turnover Patterns in a Neotropical Fish–Parasite Metanetwork
Freshwater Biology, Volume 70, Issue 7, July 2025.ABSTRACT Integrating beta‐diversity and network analyses is an emerging approach for understanding the spatial structure of species communities. For instance, although the presence of hosts affects parasite species distribution, environmental factors can either restrict or promote the occurrence of certain parasite species by changing the abundance of ...

Elevated fish growth yet postponed maturation during intense marine heatwaves
Ecological Applications, Volume 35, Issue 4, June 2025.Abstract In the last decade, the northeast Pacific Ocean has experienced new climatic extremes with the occurrence of several marine heatwaves (MHWs), prolonged periods of warmer‐than‐normal ocean temperatures, likely as a result of anthropogenic climate change.

Diversity and Distributions, Volume 31, Issue 6, June 2025.ABSTRACT Aim Copepods are the key secondary producers in marine ecosystems, yet their in situ diet and symbionts remain underexplored due to technical challenges, limiting our understanding of their population dynamics and ecological functions. Using DNA metabarcoding, we jointly characterised the natural diet and symbionts of copepods across Chinese ...

Slow Invaders Going Fast: New Data of Exotic Slugs (Gastropoda: Eupulmonata) From Spain
Ecology and Evolution, Volume 15, Issue 5, May 2025.Morphological and genetical confirmation of the occurrence of two non‐native terrestrial slugs in the Iberian Peninsula (northern Spain): Ambigolimax parvipenis and Boettgerilla pallens. ABSTRACT Invasive species are a major concern in the current scenario of biodiversity loss. Most studies focus on vertebrates and insects, while other groups have been
