Sponges and ascidians control removal of particulate organic nitrogen from coral reef water (2005, background): “, 192 fg C cell21 and 21 fg N cell21 (Heldal et al. 2003); for picoeukaryotes and nanoeukaryotes, 183 fg C mm23 and 26.”
Phosphorus availability, phytoplankton community dynamics, and taxon‐specific phosphorus status in the Gulf of Aqaba, Red Sea (2006, background): “This may be due to the greater cellular surface area to volume ratios, higher nutrient uptake efficiencies (Bertilsson et al. 2003; Heldal et al. 2003), and/or lower nutrient requirements of these organisms (Van Mooy et al. 2006).”
Elemental composition of marine Prochlorococcus and Synechococcus: Implications for the ecological stoichiometry of the sea (2003, methodology): “A recently completed study, conducted using X-ray microanalysis, also supported the result of low cellular P requirements in Prochlorococcus and Synechococcus (Table 3; Heldal et al. 2003).”
Are you what you eat? Physiological constraints on organismal stoichiometry in an elementally imbalanced world (2005, unknown): “X-ray microanalysis is a tool that may be especially useful for this question as it can identify specific storage bodies within cells (Heldal et al. 1985, 2003).”
Physiological Structure and Single‐Cell Activity in Marine Bacterioplankton (2008, background): “For example, bacteria typically have more nitrogen and phosphorus per unit carbon than algae, but unicellular cyanobacteria often have higher carbon in relation to heterotrophic microorganisms, and this has been interpreted as storage of carbon under nutrient deficiency (Heldal et al. 2003).”
Importance of a micro-diet for scleractinian corals (2004, background): “This planktonic contribution can be underestimated if the amount of nitrogen in the picoand nanoplankton is higher, as has recently been suggested (Gundersen et al. 2002, Heldal et al. 2003), but only for 1 or 2 groups of organisms.”
P-limited bacteria but N and P co-limited phytoplankton in the Eastern Mediterranean—a microcosm experiment (2005, background): “Heldal et al. (2003) have shown that N : P ratio of marine Synechococcus cultures may exceed the Redfield ratio and have argued that this capacity will be advantageous in oligotrophic, P-limited oceans.”
Environmental control of open‐ocean phytoplankton groups: Now and in the future (2010, result): “As a result of its Nrich phycobilisomes, Synechococcus also requires more N compared to Prochlorococcus (Moore et al. 2002; Heldal et al. 2003).”
CO2 concentrating mechanisms in algae: mechanisms, environmental modulation, and evolution. (2005, background): “Because the N cell quota (26, 66) is probably highly regulated in the Prochlorochoccus strains exclusively using NH4+ and organic N (213), there is less need for a modulation in DIC acquisition to maintain a (near) optimal C/N ratio.”
Picophytoplankton - a comparative study of their biochemical composition and photosynthetic properties (2005, unknown): “Synechococcus 65–293:7–36:1 Heldal et al. (2003)”
IS THE GROWTH RATE HYPOTHESIS APPLICABLE TO MICROALGAE? 1 (2010, methodology): “One option to address this issue would be to use microelemental analysis, which makes use of X-ray spectra from EM to allow for the elemental analysis of individual cells (Heldal et al. 2003, Twining et al. 2003).”
Regional variation in the particulate organic carbon to nitrogen ratio in the surface ocean (2013, result): “Thus, can differences in community composition also explain the regional variation we observe in the C:N ratio? Our taxon-specific elemental analyses show that the C:N ratio in all three small phytoplankton population are significantly higher than the canonical Redfield ratio which is consistent wit”
Photophysiology of the marine cyanobacterium Synechococcus sp. WH8102, a new model organism (2004, result): “…(279 ± 84 fg C cell–1) is not statistically different from that recently determined for WH8103 by Bertilsson et al. (2003) (213 ± 7 fg C cell–1) and Heldal et al. (2003) (220 ± 10 or 250 ± 20 fg C cell–1, depending on the culture medium) and also agrees well with that reported by Kana &…”
Physiological responses of three species of marine pico-phytoplankton to ammonium, phosphate, iron and light limitation (2005, background): “(Waterbury et al., 1979, 1986; Olson et al., 1990; Li, 1998; Bertilsson et al., 2003; Heldal et al., 2003) belong to the most thoroughly investigated algal species of the pico-phytoplankton community.”
