Species and river specific effects of river fragmentation on European anadromous fish species (2018, background): “Therefore, dam removal is preferred above fish passages as a measure to improve connectivity (Bednarek, 2001; J. E. O'Connor et al., 2015).”
Potential impacts of global climate change on freshwater fisheries (2007, background): “Worldwide, streams and lake chains have been fragmented by man-made barriers, such as dams, water diversions, and flood control structures (Porto et al. 1999; Clarkson and Childs 2000; Bednarek 2001; Lodge 2001; Winter and Van Densen 2001; Gehrke et al. 2002; Morita and Yamamoto 2002).”
Availability of and access to critical habitats in regulated rivers: effects of low‐head barriers on threatened lampreys (2009, background): “River channel barriers or levees within temperate regions are often decades or centuries old and progressive catchment management needs to consider the spatial distribution of small, but key habitat fragments in order to assess how best to reconnect these in longitudinal or lateral dimensions, as ha”
Chapter Three - From Natural to Degraded Rivers and Back Again: A Test of Restoration Ecology Theory and Practice (2011, background): “This effect depends largely on the quantity of sediments accumulated above the barrier, water velocity, the gradient of the riverbed, and also on the specific technique of weir (dam) removal (Bednarek, 2001).”
Connectivity as an emergent property of geomorphic systems (2018, positive): “After the pace of dam building increased to a peak in the mid-20th century in the US and western Europe, subsequent recognition of the detrimental effects of altered connectivity within river corridors drove efforts to remove dams or modify their operating regime (Bednarek, 2001).”
Unintended consequences and trade-offs of fish passage (2013, background): “Lastly, enthusiasm for fish passage has arisen, in part, from case studies demonstrating that enhancing fish movement via fishways or dam removal can help restore key fish populations and the ecosystem services they provide (Kanehl et al. 1997; Bednarek 2001; Graf 2003).”
THE PACIFIC SALMON WARS: What Science Brings to the Challenge of Recovering Species (2002, background): “Even passable dams can be devastating to salmon—they convert rivers into reservoirs, change aquatic communities (Bednarek 2001), and also present passage challenges to down- and upstream migrants.”
The effects of modern war and military activities on biodiversity and the environment (2015, background): “, abrasion, suffocation, habitat loss), and produce lasting physical, chemical, and biological legacies (Bednarek 2001; Stanley and Doyle 2003).”
Dispersal distance and the pool of taxa, but not barriers, determine the colonisation of restored river reaches by benthic invertebrates (2014, background): “Indeed, barrier removal and reconnecting fragmented rivers have been a strong focus of research for some time (Bednarek, 2001; Doyle et al., 2005; DeGraff & Evans, 2013).”
