摘要: The upstream effects of reservoirs on stream fish assemblages were highly localized in 3rd- through 5th-order streams the Great Plains, USA. Streams that differed connectivity to sampled at their confluences with a river or reservoir and between confluence stream's origin. Sites had higher total, nonnative, species richness than middle sites. Variability assemblage structure was influenced by catchment area, size, gradient, connectivity. Confluence sites connected correctly classified based presence red shiners (Cyprinella lutrensis) bluntnose minnows (Pimephales notatus) absence sand (Notropis stramineus); redfin (Lythrurus umbratilis). Intensive sampling across pool habitats within two isolated indicated abundance common spe...
