Functional Organization of Stream Fish Assemblages in Relation to Hydrological Variability
The strong hydrological—assemblage relations found in the 34 midwestern sites suggest thatHydrological factors are significant environmental variables influencing fish assemblage structure, and that hydrology alterations induced by climate change (or other anthropogenic disturbances) could modify stream fishassemblages structure in this region.
