This study uses environmental DNA metabarcoding to assess how pumping stations affect European eel distribution and fish species richness in wetland catchments.

The paper shows that genetic variation, not morphology, predicts migration success in Atlantic salmon, with distinct SNP sets associated with success in different rivers.

This study compares spatial ecology and population dynamics of brown trout in reservoirs with and without fish movement barriers, finding that fish passes improve connectivity but have limited overall effectiveness.

The paper uses genetic tools to assess the impact of a fishway on brown trout population connectivity, finding increased genetic differentiation after fishway installation.
