Biodiversity of traits and species both show weak responses to hydromorphological alteration in lowland river macroinvertebrates (2014, background): “Among these multiple impacts, almost all large rivers worldwide, with only a few exceptions, are fragmented by dams that alter natural flows (Poff et al., 2007) and reduce the connectivity between upstream and downstream parts of entire catchments (see also Tockner, Robinson & Uehlinger,”
Consequences of propagule dispersal and river fragmentation for riparian plant community diversity and turnover (2010, background): “The rate of extinction in freshwater ecosystems is high and increasing, and riverine and aquatic ecosystems are becoming simplified through homogenization of physical processes (Poff et al. 2007) and fragmented by impoundments (Merritt and Wohl 2006, Brown and Chenoweth 2008).”
Synchronization and portfolio performance of threatened salmon (2010, background): “In addition, dams homogenize habitats and flow regimes (Poff et al. 2007), leading to the loss of habitat variability that maintains salmonid population diversity (e.g., Beechie et al. 2006).”
Conservation from the bottom up: forecasting effects of global change on dynamics of organic matter and management needs for river networks (2011, background): “Losses of consumers are not only a consequence of stressed ecosystems, but also contribute to changes in ecosystem functioning (Dudgeon et al. 2006, Poff et al. 2007, Estes et al. 2011).”
Biodiversity, climate change, and ecosystem services (2009, background): “The modification of flow regimes over such large parts of our rivers has resulted in biotic homogenization of the fish biota of the world, fostered by the introduction of fish species favored by the thermal and flow conditions induced by dams [31].”
Safe and just Earth system boundaries (2023, positive): “In addition to direct impacts on native biodiversity, flow alteration has also been shown to favour invasive species, most often as a result of environmental homogenisation, which can lead to further biodiversity losses (Marchetti and Moyle 2001; Poff et al. 2007).”
The future of hydrology: An evolving science for a changing world (2010, background): “, 2009], in significantly distorted river flow regimes due to the building of dams [Poff et al., 2007], and in altered groundwater recharge due to changes in land use [Scanlon et al.”
Effects of connectivity, dispersal directionality and functional traits on the metacommunity structure of river benthic diatoms (2013, background): “Many studies have addressed the impact of dams on the hydrology, geomorphology and limnology of rivers (Nilsson et al., 2005; Poff et al., 2007).”
State of the world's freshwater ecosystems: physical, chemical, and biological changes. (2011, background): “Dams often stabilize discharge patterns by reducing the magnitude and duration of high flows and by supplementing low flows (71).”
