Short summary
It is increasingly recognized that marine animals host microbes relevant to nitrogen cycling. Rocky shore tidepools host a phylogenetically diverse biota that inspired us to experimentally isolate their effects on microbial nitrogen processing. We found that mussels promote high rates and diverse types of microbial nitrogen metabolisms. We further developed a novel mathematical model that quantified these diverse processes and showed their significance to nitrogen processing.
