In this study, Fanny Monteiro, Stephanie Dutkiewicz and Mick Follows, interpret the environmental controls on the global ocean diazotroph biogeography in the context of a three-dimensional global model with a self-organizing phytoplankton community.

Iron is an essential nutrient for living things, but is scarce in the ocean. Darwin Project researchers Stephanie Dutkiewisz, Mick Follows and Fanny Monteiro, collaborating with a team from WHOI led by Mak Saito are reporting they have found that a key marine bacterium, Crocosphaera watsonii, may have evolved a remarkable biochemical way to recycle iron for dual metabolic activities. You can read more about this work in the following WHOI News Office release or in Saito et al (2011), a recent paper in PNAS.
