“…Maximum growth rates of 5 species of pico-eukaryotes were reported in the range of 0.23-0.91 d À1 (Jacquet et al, 2001). Similarly, maximum growth rates in the range of 0.8-2.0 d À1 were reported for different classes of pico-eukaryotes (Glover et al, 1987). The maximum growth rates for the three species used in our study were lower than those reported in the field studies.…”

“…The fact that Synechococcus sp. had the highest K m values in our experiments confirms the apparent advantage of oceanic eukaryotic ultraplankton in low light conditions, possible due to their efficient use of dim blueviolet light (Glover et al, 1987). During our experi- (Table 5).…”

Our experimental findings once more demonstrate that the pico-phytoplankton growth rates will only be decreased at low irradiances (b10 Amol photons m À2 s À1 ).…”

Physiological responses of three species of marine pico-phytoplankton to ammonium, phosphate, iron and light limitation Timmermans, K.R.; Wagt, B. van der; Veldhuis, M.J.W.; Maatman, A.; de Baar, Henricus Take-down policy If you believe that this document breaches copyright please contact us providing details, and we will remove access to the work immediately and investigate your claim.Downloaded from the University of Groningen/UMCG research database (Pure): http://www.rug.nl/research/portal. For technical reasons the number of authors shown on this cover page is limited to 10 maximum. AbstractExperiments were conducted with three species of marine pico-phytoplankton: Synechococcus sp. (CCMP 839), Pelagomonas calceolata (CCMP 1756) and Prasinomonas capsulatus (CCMP 1617) in order to collect physiological parameters for pico-phytoplankton to be utilised in Ocean Biogeochemical Climate Models. The main parameters to follow the effects of ammonium, phosphate, iron and light limitation were cell growth rates (A), half saturation constants for growth (K m ), N, P and Fe quota (per cell or per mol C), and photochemical quantum efficiency (F v /F m ).The nitrate and phosphate limitation experiments demonstrated that the small phytoplankton species could grow at low N and P concentrations. K m values were in the micro-molar (NH 4 + ) and sub-micro-molar (PO 4 3À ) range. N and P quota were in the femto-molar range per cell and varied from nutrient-deplete to nutrient-replete conditions. F v /F m values were only adversely affected at the lowest N and P concentrations in these experiments. In the Fe limitation experiments, it was shown that all three species were adversely affected only at extremely low Fe concentrations. Iron chelating agents had to be added to force the species in Fe limitation till ultimately growth stopped. K m values with respect to dissolved Fe were in the femto-molar range. Fe quota were in the low zepto-molar (10 À21 M) range per cell, and varied considerably from Fe limiting to Fe replete growth conditions. F v /F m values diminished only at the lowest iron concentrations. In the light limitation experiments, growth rates and photochemical quantum efficiencies were adversely affected only at irradiance levels below 10 Amol photons m À2 s À1 . These results indicate that the pico-phytoplankton species will hardly ever be completely stopped in their growth by NH 4 + , PO 4 3À, Fe or light (separately) under natural conditions. D

“…Suspended particular matter entail also a different underwater light quality. Several authors have shown, that this is a controlling factor for phytoplankton growth as well (Glover et al 1987;Talling 1971). Hence, the presence of suspended particles may also be a determinant for the phytoplankton community structure in the two Jöri lakes III and VII.…”

“…The lakes containing and those lacking suspended particles showed similar phytoplankton diversity but different dominance of the algal species. According to the findings of Cuker et al (1990), this could be due to the presence of the particles but also due to different light quality caused by the particles (Glover et al 1987;Talling 1971).…”
