  abstract = {{D}espite small freshwater ecosystems being biodiversity reservoirs and contributing significantly to greenhouse fluxes, their microbial communities remain largely understudied. {Y}et, microorganisms intervene in biogeochemical cycling and impact water quality. {B}ecause of their small size, these ecosystems are in principle more sensitive to disturbances, seasonal variation and pluri-annual climate change. {H}owever, how microbial community composition varies over space and time, and whether archaeal, bacterial and microbial eukaryote communities behave similarly remain unanswered. {H}ere, we aim to unravel the composition and intra/interannual temporal dynamic patterns for archaea, bacteria and microbial eukaryotes in a set of small freshwater ecosystems. {W}e monitored archaeal and bacterial community composition during 24 consecutive months in four ponds and one brook from northwestern {F}rance by 16{S} r{RNA} gene amplicon sequencing (microbial eukaryotes were previously investigated for the same systems). {U}nexpectedly for oxic environments, bacterial {C}andidate {P}hyla {R}adiation ({CPR}) were highly diverse and locally abundant. {O}ur results suggest that microbial community structure is mainly driven by environmental conditions acting over space (ecosystems) and time (seasons). {A} low proportion of operational taxonomic units ({OTU}s) (<1%) was shared by the five ecosystems despite their geographical proximity (2-9 km away), making microbial communities almost unique in each ecosystem and highlighting the strong selective influence of local environmental conditions. {M}arked and similar seasonality patterns were observed for archaea, bacteria and microbial eukaryotes in all ecosystems despite strong turnovers of rare {OTU}s. {O}ver the 2-year survey, microbial community composition varied despite relatively stable environmental parameters. {T}his suggests that biotic associations play an important role in interannual community assembly.},
