Grazing by Karenia brevis on Synechococcus enhances its growth rate and may help to sustain blooms (2009, background): “Blooms have been hypothesized to initiate in response to organic N that becomes available following outbreaks of the cyanobacterium Trichodesmium (e.g. Walsh & Steidinger 2001, Mulholland et al. 2006).”
CO2 control of Trichodesmium N2 fixation, photosynthesis, growth rates, and elemental ratios: Implications for past, present, and future ocean biogeochemistry (2007, background): “Although the ultimate biogeochemical fate of Trichodesmium-fixed elements is not fully understood (Mahaffey et al. 2005; Mulholland et al. 2006; Mulholland 2007), any fraction of this enhanced primary productivity that is exported to underlying waters will contribute to sequestration of atmospheric…”
Carbon acquisition by Trichodesmium: the effect of pCO2 and diurnal changes (2009, background): “Elevated N2 fixation in a future ocean will likely influence phytoplankton in terms of productivity and species composition, and thereby alter the microbial food web (Mulholland et al. 2006).”
Latitudinal distribution of Trichodesmium spp. and N 2 fixation in the Atlantic Ocean (2010, background): “The use of the continuous water supply to obtain samples for Trichodesmium counts was motivated by our interest in obtaining relatively high-resolution data on Trichodesmium latitudinal distribution.”
Diazotroph derived nitrogen supports diatom growth in the South West Pacific: A quantitative study using nanoSIMS (2016, background): “In the natural environment, Trichodesmium spp. releases on average 10–50% of recently fixed N2 as dissolved organic N (DON) and NH14 (Glibert and Bronk 1994; Mulholland et al. 2006; Meador et al. 2007.”
The fate of nitrogen fixed by diazotrophs in the ocean (2007, methodology): “Based on direct estimates of N2 fixation, N release, and in situ water column N uptake rates,Trichodesmium produced ample dissolved N to fuelK. brevis growth in the Gulf of Mexico (Mulholland et al., 2006).”
Competition and facilitation between unicellular nitrogen‐fixing cyanobacteria and non—nitrogen‐fixing phytoplankton species (2007, background): “Third, nitrogen fixers can excrete fixed nitrogen (Capone et al. 1994; Mulholland and Bernhardt 2005) and may thereby facilitate growth of non-fixing species (Karl et al. 1995; Mulholland et al. 2006).”
Harmful algal blooms and eutrophication: Examining linkages from selected coastal regions of the United States (2008, methodology): “They estimated that N 2 fixation could supply up to 0.16 mM L À1 day À1 based on Trichodesmium biomass and N excretion rates measured over a 3-year period (Mulholland et al., 2006).”
Nitrogen fixation in the western English Channel (NE Atlantic Ocean) (2009, unknown): “Nitrogen fixation by Trichodesmium spp. provides a direct supply of fixed nitrogen and has been shown to support the growth of Karenia brevis in the Gulf of Mexico (Mulholland et al. 2006 ).”
