- •
Streams are affected by many simultaneously operating anthropogenic stressors.
- •
Both diffuse pollution and hydromorphological alteration may affect stream biota.
- •
Assemblages responded to diffuse pollution but not to low morphological alteration.
- •
No stressor interactions were detected across the studied stressor gradients.
- •
Mitigation of diffuse pollution should be prioritized over in-stream restoration.
