• Regional distributions of nitrogen‐fixing bacteria in the Pacific Ocean (2008, background): “Laboratory studies with Trichodesmium spp. indicate that could account for a substantial fraction of the total nitrogen demands of actively growing populations and that Trichodesmium spp. assimilation of NO {3 inhibits N2 fixation (Mulholland and Capone 2000; Holl and Montoya 2005).”
• Iron availability limits the ocean nitrogen inventory stabilizing feedbacks between marine denitrification and nitrogen fixation (2007, background): “Trichodesmium sharply reduces N fixation when nitrate is available [Holl and Montoya, 2005] as in the equatorial Pacific.”
• Nitrogenase genes in non-cyanobacterial plankton: prevalence, diversity and regulation in marine waters (2010, result): “…of Trichodesmium was not suppressed after addition of 2 mM nitrate or 0.02 mM ammonium (Ohki et al. 1991), although other studies have reported inhibition of N2 fixation in Trichodesmium by nitrate (Holl & Montoya 2005), ammonium (Capone et al. 1990) and other N sources (Mulholland & Capone 2000).”
• Burrowing deeper into benthic nitrogen cycling: the impact of bioturbation on nitrogen fixation coupled to sulfate reduction (2010, background): “Alternatively, diazotrophs may continue to fix N2 in the presence of fixed N (e.g. Holl & Montoya 2005), the reasons for which are not understood.”
• Interconnection of nitrogen fixers and iron in the Pacific Ocean: Theory and numerical simulations (2012, background): “[61] There is evidence that diazotrophs do not have to fix all the nitrogen they consume [see, e.g., Holl and Montoya, 2005]: We show here how this would affect the theoretical framework discussed in section 2.”
• Competition and facilitation between unicellular nitrogen‐fixing cyanobacteria and non—nitrogen‐fixing phytoplankton species (2007, background): “As a result, the activity of nitrogen fixation is often sensitive to the concentration of nitrate (Mulholland et al. 2001; Holl and Montoya 2005).”
• Evidence of active dinitrogen fixation in surface waters of the eastern tropical South Pacific during El Niño and La Niña events and evaluation of its potential nutrient controls (2013, background): “Moreover, NO3 is recognized to inhibit N2 fixation activity of Trichodesmium [Mulholland and Capone, 2001], although even 10 μmol L 1 NO3 did not fully inhibit nitrogenase activity in Trichodesmium [Holl and Montoya, 2005].”
