Si and C interactions in the world ocean: Importance of ecological processes and implications for the role of diatoms in the biological pump (2006, background): “Iron limitation, on the other hand, may affect the silicon metabolism by influencing the silicon uptake kinetics [Leynaert et al., 2004].”
Pseudo-nitzschia (Bacillariophyceae) species, domoic acid and amnesic shellfish poisoning: revisiting previous paradigms (2012, unknown): “Similar to other pennate diatoms (Leynaert et al. 2004), iron depletion in Pseudo-nitzschia spp. leads to a decrease in cell volume (by decreasing the cell width), cellular chlorophyll a, carbon, nitrogen and silicon cell quotas, maximum photochemical yield and growth rate (Marchetti & Harrison…”
Growth physiology and fate of diatoms in the ocean: a review (2005, background): “Similarly, very recently, Leynaert et al. (2004) observed a strong relationship between S/V ratios and Ks(Si) for one diatom species, whose size was reduced by Fe limitation: KsðSiÞ ¼ 0:64ðS=VÞ 3:66 ð6Þ with Ks(Si) in AM and S/V in Am 1, r2 = 0.9, n = 5.”
