Description
Bundy and nine co-authors report ocean experiments on how microbes cope with scarce iron, published in two thousand twenty-six. In the Southern Ocean, iron limits plant plankton growth, and bacteria release special molecules called siderophores to grab what iron there is.
In shipboard tank experiments, the team varied iron supply and tracked which siderophores appeared. The bacteria community stayed much the same, but the molecules changed: water-shy types dominated when iron was scarce, and water-friendly types when iron was added. Siderophores peaked when both plankton and bacteria were iron-starved, and plankton growth itself seemed to spur their release. The findings clarify how ocean life shares a scarce nutrient and how that sharing may respond to iron inputs.
