Different reactions of Southern Ocean phytoplankton size classes to iron fertilization (2006, methodology): “With iron fertilization, the growth rates of large diatoms increase in culture experiments (Timmermans et al. 2004) and in situ fertilization experiments.”
Adaptive strategies by Southern Ocean phytoplankton to lessen iron limitation: Uptake of organically complexed iron and reduced cellular iron requirements (2011, background): “An even greater range in Km values (0.0006–1.14 nmol L21 Fediss) has been reported for lab-cultured Southern Ocean diatoms by Timmermans et al. (2001, 2004), who suggested that Km values increase with increasing cell size.”
Fe and Zn effects on the Si cycle and diatom community structure in two contrasting high and low-silicate HNLC areas (2005, background): “For instance, Fe can induce significant alterations of diatom Si:N and Si:C stoichiometric ratios (Hutchins and Bruland, 1998; Takeda, 1998; De La Rocha et al., 2000; Firme et al., 2003; Brzezinski et al., 2003; Leynaert et al., 2004; Timmermans et al., 2004).”
Co-limitation of diatoms by iron and silicic acid in the equatorial Pacific (2011, background): “The rarity of the larger (440 mm) diatoms under ambient conditions combined with their dramatic increase in abundance in response to Fe addition suggests that their growth is strongly Fe-limited in situ consistent with the greater Fe requirement of larger diatoms (Timmermans et al., 2004).”
Late summer diatom biomass and community structure on and around the naturally iron-fertilised Kerguelen Plateau in the Southern Ocean (2008, background): “Timmermans et al. (2004) put such increased responses in F. kerguelensis down to the lower requirement of Fe to stimulate this diatom species growth in comparison to other larger species.”
Trait-Based Community Ecology of Phytoplankton (2008, background): “…trade-offs in such cases: Marine diatoms, especially large-celled species, appear to be poor competitors for another essential nutrient, iron (Litchman et al. 2006, Sarthou et al. 2005, Timmermans et al. 2004), so a trade-off may exist between maximum growth rate and iron competitive ability.”
Coupled changes in the cell morphology and elemental (C, N, and Si) composition of the pennate diatom Pseudo‐nitzschia due to iron deficiency (2007, background): “2005), a combination of increased silicic acid (Si[OH]4) and decreased nitrate (NO3) consumption (Timmermans et al. 2004), or a reduction in NO3 uptake capacity (Franck et al.”
Transformation of iodate to iodide in marine phytoplankton driven by cell senescence (2010, background): “Measured chl a and cell densities appeared similar to untreated samples, and species showed normal growth rates of µ = 0.11 to 0.31 cell doublings d–1 (Timmermans et al. 2004) through- 6 Bluhm et al.: Iodide production by marine phytoplankton out the experiments, suggesting that the added iodate…”
