Methods

All points were sampled with net of 0.8x1.2 m with 2mm. The web was released at least 40 times at each collection point or until no new species were sampled at that place after 10 consecutive realising. Dragging nets (1.5x5m with 2mm) were used at bigger rivers. Waiting nets 1.5x10 m (with 15 20 430 40 and 50 mm between opposite knots) were exposed for 15 to 18 hours (from the evening until the next morning) ? at the points E2 E3 and E4. Tadpole sampling was performed using a wire mesh dipnet (3 mm2 mesh size) for 6 years (1989-1995). Unit of abundance = IndCountInt, Unit of biomass = NA
