Background information and definitions
Rising temperatures and changes in precipitation may substantially alter river flows and lead to desiccation and fragmentation of freshwater habitats (Arnell & Gosling 2013). Managing water levels and flow in rivers to maintain deep pools and connectivity may help to conserve freshwater mammal species that rely on these habitats, such as river dolphins (Choudhary et al. 2005). This may be particularly important in arid areas or during the dry season.
