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
