Temporal Dynamics of a Fish Parasite (Tetracapsuloides bryosalmonae) and Its Two Main Hosts in Pyrenean Streams: An Environmental DNA‐Based Approach

Environmental DNA, Volume 7, Issue 3, May–June 2025.
This study used eDNA and digital PCR to track the parasite T. bryosalmonae and its hosts over a year in the Pyrenees. Results showed seasonal and spatial synchrony, especially in summer, with stronger alignment in nearby sites and where fish infection rates were high.
