Short summary

The Southwest Pacific has one of the highest N₂ fixation rates in the global ocean, yet information is scarce on the bacterioplankton interrelationships. We detected high microbial diversity in the New Caledonia lagoon and inside a 50 000 L experimental enclosure of the same water mass over 3 weeks and give evidence for previously unknown niche partitioning. Phosphate fertilization promoted the growth of efficient N₂ fixing cyanobacteria triggering the growth of most heterotrophic bacteria.
