Gene Expression Associated With Behaviour Manipulation in Wood Ants Infected With Larval Lancet Fluke, Dicrocoelium dendriticum

open access: yesMolecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT Many ant species show dramatic shifts in behaviour when infected with parasites, but the molecular basis of these behavioural changes is not well understood. An example is the wood ant, Formica aserva, which serves as an intermediate host for the lancet liver fluke, Dicrocoelium dendriticum.

Notable seasonal variation observed in the morphology of the reindeer rumen fluke (Paramphistomum leydeni) in Finland

open access: yesRangifer, 2009
Although numerous Paramphistomum species have been described from the rumen and reticulum of domestic and wild ruminants, information about rumen flukes in reindeer is sparse and their nomenclature is somewhat conflicting.

Dead or Alive? Challenges in Discriminating Dietary From Host‐Associated Community via RNA and DNA Metabarcoding in a Filter Feeder

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
The present manuscript uses time series of highly standardized samples of a freshwater and a marine mussel from Germany to explore chances and challenges of identifying their associated community composition by a parallel DNA and RNA metabarcoding approach.

Postglacial Echoes: Parasite Genomics Uncover Environmental Changes in Postglacial European Lakes

open access: yesMolecular 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
