Climate‐driven hydrological variability determines inter‐annual changes in stream invertebrate community assembly

Although flow regime is one of the major drivers of riverine communities, not much is known about how inter‐annual variability and extremes of flow influence community assembly mechanisms. We used data on benthic macroinvertebrates and modelled flow regimes in 23 near‐pristine boreal streams to assess how community assembly mechanisms and species occupancy varied in response to inter‐annual variability in flow conditions across 11 successive...
