The elemental stoichiometry of aquatic and terrestrial ecosystems and its relationships with organismic lifestyle and ecosystem structure and function: a review and perspectives (2011, background): “The buffer effect of N2 fixers around Redfield’s ratio is dependent on the availability of elements other than N and P such as Fe and Mo, which are necessary for the enzymatic fixation of N2 (Howarth et al. 1988; Wu et al. 2000; Lenton and Watson 2000).”
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, background): “However, phosphorus has received increasing attention over the last few years as a potentially limiting nutrient for Trichodesmium (Wu et al. 2000; Sañudo-Wilhelmy et al. 2001), since a lack of P has been long known to limit freshwater diazotrophs in Fe-rich lakes.”
Iron, phosphorus, and nitrogen supply ratios define the biogeography of nitrogen fixation (2013, background): “The system is controlled by wP:N only in limited regions, such as the North Atlantic (Wu et al. 2000; Moore et al. 2009; Palter et al. 2011), where wFe:N exceeds the demands of the diazotrophs.”
A microbial source of phosphonates in oligotrophic marine systems (2009, background): “Phosphorus (P) has a key role in constraining the growth of marine primary producers over both modern and geologic timescale”
Effect of nutrient amendments on bacterioplankton production, community structure, and DOC utilization in the northwestern Sargasso Sea (2002, background): “Extremely low inorganic phosphorus concentrations in the surface waters (Wu et al. 2000) would appear to support this hypothesis.”
Phosphorus availability, phytoplankton community dynamics, and taxon‐specific phosphorus status in the Gulf of Aqaba, Red Sea (2006, background): “In the Sargasso Sea, orthophosphate (Pi) is suspected to play an important role in limiting production (Wu et al. 2000; Ammerman et al. 2003).”
The Marine Nitrogen Cycle: Overview and Challenges (2008, background): “, 2005; Carpenter and Romans, 1991), yet these waters have extremely low PO 4 concentrations (Wu et al., 2000).”
Diel variation of molybdenum and iron in marine diazotrophic cyanobacteria (2004, background): “Field measurements of C : N ratios in Trichodesmium from the North Atlantic and North Pacific are generally low, ranging from 4.7 to 7.3 (Letelier and Karl 1998; Berman-Frank et al. 2001a; Kustka et al. 2002).”
Does competition for nanomolar phosphate supply explain the predominance of the cyanobacterium Synechococcus? (2002, methodology): “It has been proposed that primary production (Karl et al. 1997; Wu et al. 2000; Sañudo-Wilhelmy et al. 2001) as well as bacterial production (Thingstad and Rassoulzadegan 1999; Van Wambeke et al. 2002) are controlled by the availability of phosphate.”
Rapid biologically mediated oxygen isotope exchange between water and phosphate (2002, background): “[2] Phosphorus (P) is considered to be a limiting nutrient in some oceanic systems [Karl et al., 1995; Cotner et al., 1997; Wu et al., 2000] and is possibly the ultimate limiting macronutrient for marine productivity over long timescales [Delaney, 1998; Tyrrell, 1999].”
Iron and phosphorus co-limit nitrogen fixation in the eastern tropical North Atlantic (2004, result): “Oceanographic observations have been interpreted both to confirm and refute this hypothesi”
Dynamics of Dissolved Organic Phosphorus (2015, methodology): “This method has been used to reliably detect subnanomolar concentrations of Pi in seawater (Wu et al., 2000).”
Taxonomic variability of phosphorus stress in Sargasso Sea phytoplankton (2004, background): “…studies (Fanning 1992; Michaels et al. 1996) noted dissolved inorganic N : P ratios that were substantially greater than the canonical Redfield (1958) ratio, and that have recently been confirmed by high-sensitivity nutrient analytical methods (Wu et al. 2000; Cavender-Bares et al. 2001).”
