abstract = {The bed of fluvial ecosystems plays a major role in global biogeochemical cycles.
All fluvial sediments migrate and although responses of aquatic organisms to
such movements have been recorded there is no theoretical framework on how
the frequency of sediment movement affects streambed ecology and biogeochemistry.
We here developed a theoretical framework describing how the
moving-resting frequencies of fine-grained sediments constrain streambed communities
across spatial scales. Specifically, we suggest that the most drastic
impact on benthic and hyporheic communities will exist when ecological and
biogeochemical processes are at the same temporal scale as the sediment
moving-resting frequency. Moreover, we propose that the simultaneous occurrence
of streambed patches differing in morphodynamics should be considered
as an important driver of metacommunity dynamics. We surmise that the frequency
of patch transition will add new dimensions to the understanding of biogeochemical
cycling and metacommunities from micro-habitat to segment
scales. This theoretical framework is important for fluvial ecosystems with frequent
sediment movement, yet it could be applied to any other dynamic habitat.},
