abundance and distribution of major groups of diazotrophic cyanobacteria and their potential contribution to n₂ fixation in the tropical atlantic ocean. | the abundances of six n₂-fixing cyanobacterial phylotypes were profiled at 22 stations across the tropical atlantic ocean during june 2006, and used to model the contribution of the diazotrophs to n₂ fixation. diazotroph abundances were measured by targeting the nifh gene of trichodesmium, unicellular groups a, b, c (ucyn-a, ucyn-b and ucyn-c), and diatom-cyanobiont symbioses hemiaulus-richelia, rhizosolenia-richelia and chaetoceros-calothrix. west to east gradients in temperature, salinity and ... | 2010 | 20678117 |
nitrogen fixation and nitrogenase (nifh) expression in tropical waters of the eastern north atlantic. | expression of nifh in 28 surface water samples collected during fall 2007 from six stations in the vicinity of the cape verde islands (north-east atlantic) was examined using reverse transcription-polymerase chain reaction (rt-pcr)-based clone libraries and quantitative rt-pcr (rt-qpcr) analysis of seven diazotrophic phylotypes. biological nitrogen fixation (bnf) rates and nutrient concentrations were determined for these stations, which were selected based on a range in surface chlorophyll conc ... | 2011 | 21228888 |
