“…These flow-ecology relationships reflect a kind of "evolutionary" time scale, that is, the temporal pattern of flow variation that establishes the template on which some adaptations of species have been set (Lytle & Poff, 2004;Poff et al, 1997); this evolutionary history perspective provides theoretical expectations likely species' responses to particular kinds of flow alterations. Regime-based metrics also inform us about what type of general ecological patterns we should expect through species sorting, that is, particular patterns of flow variation act as a "filter" to favour species having attributes that match the temporal dynamics of that habitat, and disfavour those that do not, as has been shown for riparian vegetation (Merritt, Scott, Poff, Auble, & Lytle, 2010), fish (Mims & Olden, 2012;Poff & Allan, 1995) and invertebrates (Chadd et al, 2017;Kakouei, Kiese, Kails, Pusch, & J€ anig, 2017;Monk et al, 2006;Zuellig & Schmidt, 2012).…”
