Biogeography of N2 Fixation in the Surface Ocean
Diazotrophs and N 2 fixation are not homogenously distributed across the oceans, but have
distinct patterns of rates, abundances and species composition. These patterns reflect the …

Crocosphaera as a major consumer of fixed nitrogen despite its capability of nitrogen fixation
Crocosphaera watsonii (hereafter Crocosphaera) is a key nitrogen (N) fixer in the ocean, but
its ability to consume combined N sources is still unclear. Using in situ microcosm …
