Abstract:

The sinking of phytoplankton derived particulate organic matter to the deep ocean constitutes an important removal process of atmospheric CO₂ , and is termed the biological carbon pump. Understanding the taxon specific connection between phytoplankton communities in the euphotic zone and their contribution to particle flux is a high priority in current oceanographic research. I will present results from DNA-based molecular studies that investigate the taxonomic composition of cyanobacterial and protist communities retrieved from particle traps in comparison to those living in the euphotic zone. I will show what sometimes surprising insights we can gain from this approach, and how fingerprints of prey DNA recovered from guts and fecal pellets of dominant zooplankton grazers can provide a link between water column communities and those recovered from sinking particles.
