The Evolution and Ecology of Host Manipulation in Helminth Parasites: A Phylogenetic Meta‐Analysis

Ecology Letters, Volume 29, Issue 2, February 2026.
Host manipulation by parasites is wide spread but the conditions shaping it remain unclear. In a phylogenetic meta‐analysis on trophically transmitted helminths, manipulation reliably increased host predation susceptibility to predation in mature parasites, while the effect of immature parasites remained unclear.

Hepatic Morphological Lesions and Blood Biochemical Evidence of Impaired Metabolism in Wild European Moose (Alces alces) Naturally Infected With Parafasciolopsis fasciolaemorpha

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
Liver flukes may cause significant pathological changes in domestic and wild ruminants. One such parasite, Parafasciolopsis fasciolaemorpha, reported in European moose (Alces alces), still requires detailed investigation to better understand its pathogenesis and impact on host health.

Report ofNeospirorchis schistosomatoides Price 1934 (Digenea: Spirorchiidae) infecting a Green Turtle, Chelonia mydas Linnaeus, 1758 (Testudines, Cheloniidae), from Brazil

Helminthologia, 2016
We report the occurrence of Neospirorchis schistosomatoidesPrice 1934 in a juvenile green turtle (Chelonia mydas L.1758) from the Brazilian coast. This species has been reported only in green turtles from the USA, Bermuda and Australia.

Diversity and parasitological assessment of Digenea species in Trachurus trachurus (Teleostei, Carangidae) from the Algerian coast, Western Mediterranean

Helminthologia
A total of 820 specimens of Trachurus trachurus (Linnaeus, 1758) were collected from various locations along the Algerian coast between July 2023 and July 2024 and examined for digenean parasites. Among them, 27.68% were found to be infected. In total, 1,

From Mud to Meat: Comparative Metabarcoding Reveals Two Different Evolutionary Paths to Carnivory in a Group of Meiofaunal Annelids

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Evolutionary transitions to carnivory represent profound shifts in feeding mode that are often accompanied by widespread changes in organismal function, behaviour and ecology. Such transitions have evolved numerous times among animals, and predator–prey interactions have been major drivers of animal evolution.

Insights into mucosal and systemic immune responses of African catfish, Clarias gariepinus, to chilodonellosis: A natural infection study

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
