  abstract = {{F}reshwater ecosystems are among the most endangered ecosystem in the world. {U}nderstanding how human activities affect these ecosystems requires disentangling and quantifying the contribution of the factors driving community assembly. {W}hile it has been largely studied in temperate freshwaters, tropical ecosystems remain challenging to study due to the high species richness and the lack of knowledge on species distribution. {H}ere, the use of e{DNA}-based fish inventories combined to a community-level modelling approach allowed depicting of assembly rules and quantifying the relative contribution of geographic, environmental and anthropic factors to fish assembly. {W}e then used the model predictions to map spatial biodiversity and assess the representativity of sites surveyed in {F}rench {G}uiana within the {EU} {W}ater {F}ramework {D}irective ({WFD}) and highlighted areas that should host unique freshwater fish assemblages. {W}e demonstrated a mismatch between the taxonomic and functional diversity. {T}axonomic assemblages between but also within basins were mainly the results of dispersal limitation resulting from basin isolation and natural river barriers. {C}ontrastingly, functional assemblages were ruled by environmental and anthropic factors. {T}he regional mapping of fish diversity indicated that the sites surveyed within the {EU} {WFD} had a better representativity of the regional functional diversity than taxonomic diversity. {I}mportantly, we also showed that the assemblages expected to be the most altered by anthropic factors were the most poorly represented in terms of functional diversity in the surveyed sites. {T}he predictions of unique functional and taxonomic assemblages could, therefore, guide the establishment of new survey sites to increase fish diversity representativity and improve this monitoring program.},
