We examined inter-habitat variation in benthic macroinvertebrate assemblages in the 180-km Garrison Reach of the Upper Missouri River, North Dakota (USA) in 2001–2003. The Garrison Reach is unchannelized with a mostly rural setting. Flows are regulated by Garrison Dam.We sampled benthos from three habitats defined a priori: channel, shoreline, and backwater. Benthic assemblages were different i...

Even under current sea level conditions, many communities are working to protect their coastlines against flooding and shoreline erosion. Coastal often shorelines excessive erosion by using armoring techniques (e.g., bulkheads, riprap). Yet hardened structures reduce of the natural adaptive mechanisms present in coastal ecosystems sustainability system. In contrast, nature-based features living...

Bank habitats provide important functions for riverine fish. Yet, they have been heavily modified by land use, technical flood protection measures, and hydropower installations. Fish species requiring specific to complete their life cycle strongly declined therefore become target of river restoration measures. This study compared abiotic conditions fish community composition three bank habitat ...
