Different reactions of Southern Ocean phytoplankton size classes to iron fertilization (2006, background): “The small diatom Chaetoceros brevis did not change its growth rates under different iron concentrations in laboratory experiments, leading to the assumption that this species is not iron limited under natural conditions (Timmermans et al. 2001).”
Growth physiology and fate of diatoms in the ocean: a review (2005, background): “The corres- ponding FeV is then far too low for sustaining growth of even the small phytoplankton species (Timmermans et al., 2001b), and some Fe organic complexes may be a source of available Fe for phytoplankton growth (Soria-Dengg and Horstmann, 1995; Hutchins et al., 1999; Maldonado and…”
Mesoscale distribution of dominant diatom species relative to the hydrographical field along the Antarctic Polar Front (2002, background): “Further, Timmermans et al. (2001) have shown that the small-celled Antarctic Chaetoceros brevis can grow at much lower iron levels than the very much larger, chain-forming C. dichaeta, which belongs to the C. atlanticus complex.”
Co-limitation by iron and light of Chaetoceros brevis, C. dichaeta and C. calcitrans (Bacillariophyceae) (2001, background): “The shipboard experiments described in this paper are the first experiments ever done with unialgal phytoplankton cultures under natural conditions (no EDTA) and confirm previous findings of shipboard experiments (Timmermans et al. 2001).”
Physiological responses of three species of marine pico-phytoplankton to ammonium, phosphate, iron and light limitation (2005, methodology): “It is generally assumed that the smaller sized phytoplankton species, due to a large surface to volume ratio, possess an ecological advantage in terms of having a smaller nutrient (iron) requirement or a more efficient uptake of iron compared to larger species (Boyd et al., 2000; Timmermans et al., ”
Effects of iron limitation on photosynthesis and carbohydrate metabolism in the Antarctic diatom Chaetoceros brevis (Bacillariophyceae) (2004, background): “A possible explanation for the small impact of iron limitation on growth rate is that C. brevis has lower iron requirements for growth than larger diatoms such as C. dichaeta (Timmermans et al., 2001).”
NUTRIENT LIMITATION AND HIGH IRRADIANCE ACCLIMATION REDUCE PAR AND UV‐INDUCED VIABILITY LOSS IN THE ANTARCTIC DIATOM CHAETOCEROS BREVIS (BACILLARIOPHYCEAE) 1 (2005, background): “Increased antioxidant capacity was found in Chlamydomonas reinhardtii, benthic diatoms, dinoflagellates, and macroalgae in response to high irradiance and chronic UV exposure (Lesser et al. 1996, Rijstenbil et al. 2000, Rossa et al. 2002, Trebst et al. 2002).”
Adaptive strategies by Southern Ocean phytoplankton to lessen iron limitation: Uptake of organically complexed iron and reduced cellular iron requirements (2011, background): “In contrast, Timmermans et al. (2001) have suggested that the cellular Fe demands of some Southern Ocean diatoms exceed those of both oceanic and coastal diatoms from temperate regions, with low and high Fe requirements respectively, and that cellular Fe requirements increase with 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): “Fe limitation also controls community structure in these regions, preventing the growth of larger species with high half-saturation constants for Fe uptake (Gall et al., 2001; Sedwick et al., 2000; Timmermans et al., 2001).”
