Results of recent modelling efforts imply denitrification-influenced waters, such as those in the Eastern Tropical South Pacific (ETSP), may support high rates of biological nitrogen fixation (BNF), yet little is known about the N2 -fixing microbial community in this region. Our characterization of the ETSP diazotrophic community along a gradient from upwelling-influenced to oligotrophic waters did not detect cyanobacterial diazotrophs commonly found in other open ocean regions. Most of the… CONTINUE READING
