  abstract = {{C}oral reefs are threatened by global warming, which disrupts the symbiosis between corals and their photosynthetic symbionts ({S}ymbiodiniaceae), leading to mass coral bleaching. {P}lanktonic diazotrophs or dinitrogen ({N}-2)-fixing prokaryotes are abundant in coral lagoon waters and could be an alternative nutrient source for corals. {H}ere we incubated untreated and bleached coral colonies of {S}tylophora pistillata with a {N}-15(2)-pre-labelled natural plankton assemblage containing diazotrophs. {N}-15(2) assimilation rates in {S}ymbiodiniaceae cells and tissues of bleached corals were 5- and 30-fold higher, respectively, than those measured in untreated corals, demonstrating that corals incorporate more nitrogen derived from planktonic diazotrophs under bleaching conditions. {B}leached corals also preferentially fed on {S}ynechococcus, nitrogen-rich picophytoplanktonic cells, instead of {P}rochlorococcus and picoeukaryotes, which have a lower cellular nitrogen content. {B}y providing an alternative source of bioavailable nitrogen, both the incorporation of nitrogen derived from planktonic diazotrophs and the ingestion of {S}ynechococcus may have profound consequences for coral bleaching recovery, especially for the many coral reef ecosystems characterized by high abundance and activity of planktonic diazotrophs.},
