Fossil Plankton Shells Show Reduced Nitrogen Fixation in Warmer Oceans 3 Million Years Ago

This research reveals that nitrogen fixation, a crucial process supporting plankton growth and the marine food web, was reduced in warmer ocean conditions 3 million years ago. The study highlights the balance between nitrogen fixation and denitrification in the global nitrogen cycle and its sensitivity to climate changes.
