      abstract     = {Iron limitation often results in increased cellular silica
                      contents of diatoms, suggesting that diatoms grow thicker
                      and possibly mechanically stronger frustules when limited.
                      We performed stability measurements for six diatom species
                      grown under iron-limitation and iron-sufficient conditions.
                      Frustule strength increased in all species when grown under
                      iron limitation, with this effect being statistically
                      significant for four of them. Valve morphology and silica
                      content of the pennate Fragilariopsis kerguelensis and the
                      centric Coscinodiscus wailesii changed under iron limitation
                      but only valve morphology changes were significant; F.
                      kerguelensis grew thicker costae while C. wailesii had
                      smaller pores, especially in the outer part of the valves.
                      These morphological changes are clearly in agreement with
                      increased mechanical strength. Increased cellular silica
                      concentrations in diatoms grown under iron limitation do
                      result in increased frustule strength, most likely improving
                      their protection against grazers.},
