The fate of nitrogen fixed by diazotrophs in the ocean (2007, methodology): “At BATS, Sheridan et al. (2002) report that bacteria were enriched on average 401 and 1709 times onTrichodesmium puffs and tufts, respectively.”
Modeling the distribution of Trichodesmium and nitrogen fixation in the Atlantic Ocean (2004, background): “Trichodesmium appears to have a very flexible phosphorus requirement [Krauk, 2001], and readily grows [Carpenter and Romans, 1991; Orcutt et al., 2001] in waters where the ambient phosphorus concentrations are extremely low (e.g., in the Sargasso Sea [Wu et al., 2000]).”
Burrowing deeper into benthic nitrogen cycling: the impact of bioturbation on nitrogen fixation coupled to sulfate reduction (2010, unknown): “For instance, the marine cyanobacteria Trichodesmium spp. exhibit ratios closer to 3:1 as determined by direct 15N2 comparisons (Orcutt et al. 2001, Capone et al. 2005) and with particulate organic nitrogen (PON) accumulation in cultures of Trichodesmium spp. (Mulholland & Capone 2001).”
Occurrence of benthic microbial nitrogen fixation coupled to sulfate reduction in the seasonally hypoxic Eckernförde Bay, Baltic Sea (2012, background): “N2 fixation rates were calculated from the linear portion of the NA results using a conversion factor of 3 C2H4 : 1 N2, which is based on previous direct15N2 comparisons in seagrass habitats (Patriquin and Knowles, 1972; O’Donohue et al., 1991) and with the marine cyanobacteria Trichodesmium(Orcutt ”
A REVISED ESTIMATE OF THE IRON USE EFFICIENCY OF NITROGEN FIXATION, WITH SPECIAL REFERENCE TO THE MARINE CYANOBACTERIUM TRICHODESMIUM SPP. (CYANOPHYTA) 1 (2003, background): “However, in Trichodesmium field and laboratory populations (Mulholland and Capone 2001, Orcutt et al. 2001) 1 mol N2 fixation requires a net investment of only 6 mol reducing equivalents, as evidenced by a mean 15N2 fixation:C2H2 reduction ratio of about 3.”
Iron requirements for dinitrogen‐ and ammonium‐supported growth in cultures of Trichodesmium (IMS 101): Comparison with nitrogen fixation rates and iron: carbon ratios of field populations (2003, unknown): “An acetylene reduction : N2 fixation ratio of 3 : 1 was assumed, based on mean ratios of 15N2 fixation : C2H2 reduction from both field and lab populations of Trichodesmium (Mulholland and Capone 2001; Orcutt et al. 2001).”
Nitrogen fixation by Trichodesmium spp.: An important source of new nitrogen to the tropical and subtropical North Atlantic Ocean (2005, unknown): “Hood et al. [2001] exploited the BATS data set, including observations of Trichodesmium abundance [Orcutt et al., 2001] in a one-dimensional model.”
Distribution of diverse nitrogen fixers in the global ocean (2010, background): “Trichodesmium biomass varies between about 2 × 10−5 mmolP l−1 in the late Spring to about 13 × 10−5 mmolP l−1 in the late summer, consistent with time‐series observations [Orcutt et al., 2001].”
Nitrogen fixation and release of fixed nitrogen by Trichodesmium spp. in the Gulf of Mexico (2006, methodology): “Rates of uptake were calculated based on the equations of Montoya et al. (1996) and Orcutt et al. (2001) using a mixing model N uptake ~ atom % PONð Þfinal { atom % PONð Þinitial atom % enrichment N source pool { atom % PONð Þinitial | time | PON½ ð1Þ C uptake ~ atom % POCð Þfinal{ atom % POCð…”
Biomass and primary productivity of the cyanobacterium Trichodesmium spp. in the tropical N Atlantic ocean (2004, background): “Orcutt et al. (2001) recently reported on the distribution of Trichodesmium biomass at the Bermuda Atlantic Time Series (BATS) station, finding an average of 16% of trichomes in colonies.”
The effect of growth rate, phosphorus concentration, and temperature on N2 fixation, carbon fixation, and nitrogen release in continuous cultures of Trichodesmium IMS101 (2005, methodology): “Similarly, Orcutt et al. (2001) reported an average ratio of about 3 : 1, with considerable variance around that mean, for a multiyear study at the Bermuda Atlantic Time Series (BATS) station.”
Polyphosphate in Trichodesmium from the low‐phosphorus Sargasso Sea (2010, background): “…this could result in elevated polyP, the phosphocline ranged from 160 to 300 m on this transect, which is deeper than Trichodesmium is likely to migrate (White et al. 2006a), and is deeper than Trichodesmium is typically observed in this region (Orcutt et al. 2001; Davis and McGillicuddy 2006).”
Dissolved inorganic and organic phosphorus uptake in Trichodesmium and the microbial community: The importance of phosphorus ester in the Sargasso Sea (2010, background): “Phosphorus (P) has increasingly been identified as a limiting nutrient in the ocean gyres, particularly in the Sargasso Sea region of the North Atlantic (Wu et al. 2000; Maranon et al. 2003).”
Phosphate availability and the ultimate control of new nitrogen input by nitrogen fixation in the tropical Pacific Ocean (2007, background): “Atmospheric input of dust, which is highly enriched in Fe relative to other nutrients, plays a significant role in the distribution of Trichodesmium (Orcutt et al., 2001) and on the decoupling between N-P-Fe-Si biogeochemical cycles in the ocean (Karl, 2002).”
