Differential processing of dissolved and particulate organic matter by deep-sea sponges and their microbial symbionts
Deep-sea sponges create hotspots of biodiversity and biological activity in the otherwise barren deep-sea. However, it remains elusive how sponge hosts and their microbial symbionts acquire and process food in these food-limited environments. Therefore, we traced the processing (i.e. assimilation an...

Deep-sea sponges create hotspots of biodiversity and biological activity in the otherwise barren deep-sea.
