  abstract = {{B}ackground {D}eforestation is a widespread disturbance for neotropical freshwater ecosystems. {W}hile biodiversity declines have been associated with deforestation, its functional consequences for stream and river fish faunas remain poorly understood. {I}n this study, we explored how deforestation affects the different facets of the functional structure of fish communities inventoried using environmental {DNA} metabarcoding in 64 river and 35 stream sites of {F}rench {G}uiana. {S}pecifically, we investigated how functional richness, divergence, evenness and identity of fish faunas are affected by deforestation.{R}esults{W}e showed that anthropogenic disturbances in {F}rench {G}uiana are modifying the functional diversity of freshwater fish communities. {T}hese disturbances not only affected the amount of functional traits held by the communities but also the identity of the traits and the internal structure of the functional space. {C}onsequently, different facets of the functional diversity supported by fish assemblages were altered. {I}n streams, deforestation did not affect the overall diversity of traits but reduced functional redundancy, underlined by a shift in functional identity towards assemblages dominated by pelagic detritivores. {I}n contrast, river fish faunas experienced a decline in functional richness, paired with shifts in functional identity and a loss of fish species with extreme functions.{C}onclusions{T}he response to deforestation differed between streams and rivers, but it supports the hypothesis that deforestation is linked to functional changes in fish assemblages. {B}y diminishing the range of the functions in rivers or by jeopardizing the redundancy of functions in streams, deforestation could severely hamper the functioning and stability of neotropical freshwater ecosystems.},
