Short summary
Microbial assemblages on host plants and animals are an increasingly recognized biological phenomenon. We present evidence that microbes in association with mussels and seaweeds are contributing greatly to nitrogen cycling in coastal marine areas, often many times that of the microbes that are simply free-living in seawater. The addition of dissolved organic carbon increased nutrient uptake by microbes, suggesting that coastal species enhance microbial metabolism through resource provisioning.
