Abstract:
Eight different cyanobacterial diazotrophs (Trichodesmium spp., UCYN-A1, UCYN-A2, UCYN-B, UCYN-C, het-1, het-2 and het-3), and two phytoplankton hosts (UCYN-A1 and A2 hosts), were quantified by their nifH genes (18S rRNA for the hosts) in the western tropical South Pacific in spring 2015. The qPCR data was generated at 18 stations along a west to east transect from New Caledonia to Tahiti, covering oligotrophic to ultra-oligotrophic waters.
