Lauderdale, Jonathan Maitland; Braakman, Rogier; Forget, Gaël; Dutkiewicz, Stephanie; Follows, Michael J. (2020): Microbial feedbacks optimize ocean iron availability. In Proceedings of the National Academy of Sciences of the United States of America. DOI: 10.1073/pnas.1917277117.
„Dissolved iron is quickly lost from the ocean, but its availability to marine microbes may be enhanced by binding with organic molecules which, in turn, are produced by microbes. We hypothesize this forms a reinforcing cycle between biological activity and iron cycling that locally matches the availability of iron and other nutrients, leading to global-scale resource colimitation between macronutrients and micronutrients, and maximizing biological productivity.“
