1 Introduction Dispersal plays an important role in driving species' distributions, providing access to different habitats that support recruitment and promoting gene flow between subpopulations (Hanski 1998; Heggenes et al. 2006; Radinger and Wolter 2014). The construction of dams and weirs to regulate rivers has caused major losses of lotic habitats, reduced longitudinal connectivity, altered floodplain function and has ultimately resulted in biodiversity declines globally (Grill et al. 2019).
