  abstract = {{L}ittle is known about the ability of phages to successfully colonize contrasting aquatic niches. {W}e conducted experimental cross-infections between viruses and prokaryotes from three tropical sites of {W}est {A}frica, with distinct salinities: a freshwater reservoir, a marine coastal station and a hypersaline lake. {A} cellular poison-based method (potassium cyanide) revealed that the addition of native viruses (regardless of the water type) consistently stimulated viral production. {C}onversely, in all incubations conducted with allochtonous (non-native) viruses, their overall production was not promoted, which suggests a lytic failure. {P}rokaryotic heterotrophic production increased in fresh and marine water supplemented with native viruses, but not in the hypersaline water. {T}hese results point to the role of the viral shunt in low-salinity environments, where the release of bioavailable lysis products might be of high nutritional value for the noninfected prokaryotes. {I}n contrast, in hypersaline water where glycerol is a major carbon and energy source for the heterotrophic community, dissolved organic matter ({DOM}) of lytic origin may represent a less important {DOM} source for prokaryotes. {F}inally, our results suggest that cosmopolitan phages capable of moving between biomes are probably rare in aquatic habitats, supporting the common idea that most wild phages are relatively limited in their host range.},
