  abstract = {{D}iazotrophs provide a significant reactive nitrogen source in the ocean. {I}ncreased warming and stratification may decrease nutrient availability in the future, forcing microbial communities toward using dissolved organic matter ({DOM}). {N}ot depending on reactive nitrogen availability, diazotrophs may be "winners" in a nutrient-depleted ocean. {H}owever, their ability to exploit {DOM} may influence this success. {W}e exposed cultures of the widespread {C}rocosphaera to low (26 degrees {C}, p{H} 8.1), moderate (28 degrees {C}, p{H} 8.0), and extreme (30 degrees {C}, p{H} 7.9) climate change scenarios, under control or {DOM}-amended conditions. {G}rowth was suboptimal in the low and extreme treatments and favored in the moderate treatment. {DOM} was preferred as a carbon source regardless of the treatment and promoted {N}-2 fixation in extreme conditions. {T}his was reflected in the increased expression of photosynthesis genes to obtain energy. {DOM} provides {C}rocosphaera with a key ecological advantage, possibly dictating diazotroph-derived nitrogen inputs in the future ocean.},
