This paper compares physical-habitat variables, taxonomic and functional-trait diversities, taxonomic composition, and functional-trait abundances between 24 pairs of upstream (control) and downstream reconfigured (restored) reaches in 3 catchment land uses (urban, agricultural, rural) across the North Carolina Piedmont. Our results highlight 2 important aspects of channel reconfiguration as a restoration practice: 1) responses differ between restored agricultural/rural and urban catchments and 2) channel reconfiguration disturbs food and habitat resources in stream ecosystems.
