Alteration of hydrologic variability is considered a key pathway by which urbanization affects stream assemblages; however, understanding the mechanisms of alteration remains a challenge.

One approach is to identify biological metrics that show distinct responses to flows, which can be used to assess effectiveness of flow management strategies (e.g., stormflow abstraction and infiltration).

In each of six suburban, headwater streams (0.26?1.8 km2) in Cincinnati, OH (USA), we sampled continuous stream discharge, monthly baseflow water quality, and seasonal macroinvertebrate assemblages (5...
