  abstract = {{T}he effect of drying events on aquatic biodiversity is still overlooked in wet {N}eotropical systems. {Y}et, the responses of local communities and metacommunities in these biodiversity hotspots may differ from what is reported in other areas. {W}e addressed the effect of drying events on local and regional fish and macroinvertebrate communities in the headwaters of the {C}hipiriri {R}iver basin, in the wet {N}eotropical piedmont of {B}olivia. {A}ccording to current knowledge in intermittent rivers and ephemeral streams ({IRES}) ecology, we predicted that intermittent ({INT}) sites would harbour lower -diversity, but higher -diversity, than perennial ({PER}) sites, due to local, negative effect of drying combined with the existence of multiple recovery stages at the network scale. {A}lthough habitat variables were similar between {INT} and {PER} sites, local and regional diversity patterns differed. {L}ocal invertebrate communities were not different between site types as soon as 4-6weeks after flow resumption. {T}he proximity of colonist sources and frequent rainfall probably enhanced persistence through dry periods and high resilience. {I}n contrast, fish communities were still poorer at {INT} than {PER} sites, indicating they were still in the process of recolonising upstream {INT} reaches. -diversity analyses confirmed that invertebrate and fish metacommunities were not at the same recovery stage because (i) -diversity of invertebrates was best explained by physical and environmental distances at both {INT} and {PER} sites, whereas that of fish was explained only by physical distances at {INT} sites; (ii) fish -diversity was higher at {INT} than at {PER} sites, but invertebrate -diversity was similar; and (iii) physical distances were correlated with the turnover component of invertebrate -diversity but with the nestedness component for fish. {E}xploring regional community patterns in {IRES} and across biota with different dispersal abilities and modes can advance metacommunity theory and improve our ability to predict local community composition in dynamic ecosystems.},
