“…The development of habitat selection models, in combination with hydraulic models and integrated into water management software, has contributed to understand the variations in habitat suitability (often for fish and macroinvertebrates) as a function of flow alteration (e.g., Conallin, Boegh, & Jensen, 2010;Garbe & Beeyers, 2017;Hayes, Hughes, & Kelly, 2007;Lamouroux, Mérigoux, Dolédec, & Snelder, 2013;Poff et al, 2010;Rosenfeld, 2017;Tomsic, Granata, Murphy, & Livchak, 2007). Probably due to the strong variations in local hydraulics within rivers and their strong dependence on discharge, many fish habitat selection models were developed at the microhabitat scale (e.g., Booker & Graynoth, 2013;Lamouroux, Capra, Pouilly, & Souchon, 1999;Mouton et al, 2012), which represent the immediate and daily habitat occupied by fish (Odum, 1953), or at the mesohabitat scale (e.g., Booker & Graynoth, 2013;Gosselin, Maddock, & Petts, 2012;Vezza, Parasiewicz, Calles, Spairani, & Comoglio, 2014), which represent the functional habitat for fish activities (Kemp et al, 1999). Thus, microhabitat and mesohabitat models allow studying local processes involved in fish ecology, considering fish sensitivity to local hydraulic variations.…”
