Among phytoplankton the diatoms are strong competitors and contribute significantly to total global primary production. Aspects of their life history, notably their high sinking rates, make them important to the export flux of carbon into the ocean interior. Unlike the majority of other phytoplankton, they utilize silicic acid (=silicate) to construct their cell walls and are controlled by its availability and distribution. Here a simple model is developed to study the relationship between the… 
Physiological and biochemical responses of Thalassiosira punctigera to nitrate limitation
Marine diatoms play an important role in the global primary production and contribute significantly to carbon export in upwelling regions. However, their carbon fixation is frequently limited by
Diatom carbon export enhanced by silicate upwelling in the northeast Atlantic
It is shown that, with nitrate still available for new production, the diatom bloom is prolonged where there is a periodic supply of new silicate: specifically, diatoms thrive by ‘mining’ deep-water silicate brought to the surface by an unstable ocean front.
Selective silicate-directed motility in diatoms
It is shown that benthic diatoms selectively perceive and behaviourally react to gradients of dSi and the ability to exploit local and short-lived dSi hotspots using a specific search behaviour likely contributes to micro-scale patch dynamics in biofilm communities.
Quantifying the Cenozoic marine diatom deposition history: links to the C and Si cycles
Abstract. Marine planktonic diatoms are, today, among the world's main primary producers as well as the main organic carbon exporter to the deep sea despite the fact that they were a very minor
Influence of consumer-driven nutrient recycling on primary production and the distribution of N and P in the ocean
In this model, N deficit or N excess in the deep ocean resulted not only from the balance between N2-fixation and denitrification, but also from CNR, especially when the elemental composition of producers and consumers differed substantially.
Can Organisms Regulate Global Biogeochemical Cycles?
Global biogeochemical cycles are being profoundly affected by human activities; therefore, it is critical to understand the role played by organisms in their regulation. Autotrophic organisms can
Nutrient consumption and chain tuning in diatoms exposed to storm-like turbulence
This work shows that the chain-forming diatom Chaetoceros decipiens, continues to take up phosphorus and carbon even when silicon is depleted during turbulence, and partly corroborate Margalef's mandala.
Low efficiency of nutrient translocation for enhancing oceanic uptake of carbon dioxide
Anthropogenic emissions of carbon dioxide (CO2) are steadily increasing the concentration of this greenhouse gas in the Earth's atmosphere. The possible long-term consequences of this elevated
Genome-Wide Transcriptome Analyses of Silicon Metabolism in Phaeodactylum tricornutum Reveal the Multilevel Regulation of Silicic Acid Transporters
Global analyses revealed that about one fourth of the differentially expressed genes are organized in clusters, underlying a possible evolution of P. tricornutum genome, and perhaps other pennate diatoms, toward a better optimization of its response to variable environmental stimuli.


Influence of iron availability on nutrient consumption ratio of diatoms in oceanic waters
The major nutrients (nitrate, phosphate and silicate) needed for phytoplankton growth are abundant in the surface waters of the subarctic Pacific, equatorial Pacific and Southern oceans, but this
Iron-limited diatom growth and Si:N uptake ratios in a coastal upwelling regime
There is compelling evidence that phytoplankton growth is limited by iron availability in the subarctic Pacific, and equatorial Pacific and Southern oceans. A lack of iron prevents the complete
Temporal decoupling of carbon and nitrogen dynamics in a mesocosm diatom bloom
Flows of the major biogeochemical elements (C, N, P, Si) and of transparent exopolymer particles (TEP) were traced during a bloom of a natural assemblage of marine diatoms in a mesocosm (1 m3) to
Silica production and the contribution of diatoms to new and primary production in the central North Pacific
The silica cycle in the upper 200 m of the central North Pacific was examined to further assess the role of oligotrophic mid-ocean gyres in the global marine silica cycle and to evaluate the role of
Silicate regulation of new production in the equatorial Pacific upwelling
Surface waters of the eastern equatorial Pacific Ocean present the enigma of apparently high plant-nutrient concentrations but low phytoplankton biomass and productivity. One explanation for this
Role of sinking in diatom life-history cycles: ecological, evolutionary and geological significance
Rapid mass sinking of cells following diatom blooms is argued here to represent the transition from a growing to a resting stage in the life histories of these algae.
Architecture and material properties of diatom shells provide effective mechanical protection
It is concluded that diatom frustules have evolved as mechanical protection for the cells because exceptional force is required to break them.
A Proton Buffering Role for Silica in Diatoms
It is shown that the biosilica of diatoms is an effective pH buffer, enabling the enzymatic conversion of bicarbonate to CO2, an important step in inorganic carbon acquisition by these organisms.
The goal of this review is to present an overview of silicon metabolism in diatoms and to identify areas for future research.
