Diatoms (Bacillariophyta) constitute one of the most diverse and ecologically important groups of phytoplankton. [] Key Result We provide a new estimate of diversity of marine planktonic diatoms at 4,748 operational taxonomic units (OTUs).

Exploring diatoms functional and taxonomic diversity on a global scale through an integrative approach

The first assessment of diatom taxonomic richness at a global scale together with its statistical modeling using a machine-learning approach is described, and a completely new approach to characterize the functional diversity is provided.

Diatoms structure the plankton community based on selective segregation in the world’s ocean

It is shown that only 13% of diatom pairwise associations are driven by environmental conditions, whereas the vast majority are independent of abiotic factors, which indicates that their biogeography is constrained by top down pressure.

The evolution of diatoms and their biogeochemical functions

The current review aims to synthesize current information about the evolution and biogeochemical functions of diatoms as they rose to prominence in the global ocean.

Contrasting biogeography and diversity patterns between diatoms and haptophytes in the central Pacific Ocean

Examination of basin-scale variability of the abundance and taxonomic composition of these two phytoplankton groups across 35 sites in the Pacific Ocean using DNA metabarcoding supports the notion that their distinct ecological strategies underlie the emergence of contrasting diversity patterns of these phy toplankston groups in the central Pacific at a basin scale.

Extreme Diversity of Diplonemid Eukaryotes in the Ocean

PhytoBase: A global synthesis of open-ocean phytoplankton occurrences

Abstract. Marine phytoplankton are responsible for half of the global net primary production and perform multiple other ecological functions and services of the global ocean. These photosynthetic

Nanoplanktonic diatoms are globally overlooked but play a role in spring blooms and carbon export

A massive spring bloom of the smallest known diatom (Minidiscus) in the northwestern Mediterranean Sea is described, implying the need to revise the classical binary vision of pico- and nanoplanktonic cells fueling the microbial loop, while only microphytoplankton sustain secondary trophic levels and carbon export.

Diatoms shape the biogeography of heterotrophic prokaryotes in early spring in the Southern Ocean

This work investigates the relationship between assemblages of diatoms and of heterotrophic prokaryotes in surface waters of the Indian sector of the Southern Ocean in early spring and identifies a large number of highly significant correlations between abundant diatom species and proKaryotic taxa.

Chemotaxonomic characterization of the key genera of diatoms in the Northern Antarctic Peninsula.

Diatoms are successful in occupying a wide range of ecological niches and biomes along the global ocean. Although there is a recognized importance of diatoms for the Southern Ocean ecosystems and

Molecular biogeography of planktonic and benthic diatoms in the Yangtze River

It is revealed that benthic diatoms are of particular significance in characterizing motile guild in riverine environments, which provides insights into diatom biogeography and biogeochemical cycles in large river ecosystems.

Controls on Diatom Biogeography in the Ocean

Fossil records show that the dispersal of diatoms from ocean plankton has not been constrained by geographical barriers, suggesting that the biodiversity at the microbial level fundamentally differs from that of macroscopic animals and plants for which geographic isolation is a common component of speciation.

Eukaryotic plankton diversity in the sunlit ocean

Diversity emerged at all taxonomic levels, both within the groups comprising the ~11,200 cataloged morphospecies of eukaryotic plankton and among twice as many other deep-branching lineages of unappreciated importance in plankton ecology studies.

A global diatom database – abundance, biovolume and biomass in the world ocean

This first attempt to compile the largest possible body of data available from different databases as well as from individual published or unpublished datasets regarding diatom distribution in the world ocean using a single standardized method is compiled.

Patterns of Diversity in Marine Phytoplankton

A global ocean circulation, biogeochemistry, and ecosystem model indicated a decrease in phytoplankton diversity with increasing latitude, consistent with observations of many marine and terrestrial taxa.

Oceanographic and biogeochemical insights from diatom genomes.

It is shown how genome-enabled approaches are being leveraged to explore major phenomena of oceanographic and biogeochemical relevance, such as nutrient assimilation and life histories in diatoms.

The diversity and distribution of diatoms: from cosmopolitanism to narrow endemism

Evidence that challenges the ubiquity hypothesis for the most speciose group of microbial eukaryotes, the diatoms, and underscores the pressing need to continue research into diatom biology, ecology and the factors driving diatom species diversity and geographic distributions is reviewed is reviewed.

A latitudinal diversity gradient in planktonic marine bacteria

The latitudinal gradient in marine bacteria supports the hypothesis that the kinetics of metabolism, setting the pace for life, has strong influence on diversity.

Historical processes constrain patterns in global diatom diversity.

Using a global freshwater diatom data set, it is shown that latitudinal gradients in local and regional genus richness are present and highly asymmetric between both hemispheres, stressing the importance of dispersal and migration in structuring diatom communities at regional to global scales.

Response of diatoms distribution to global warming and potential implications: A global model study

Using a global model of ocean biogeochemistry coupled to a climate model, we explore the effect of climate change on the distribution of diatoms, a key phytoplankton functional group. Our model

Making sense of ocean biota: How evolution and biodiversity of land organisms differ from that of the plankton

It is argued that organism interactions, in particular co-evolution between predators and prey (the arms race), play a central role in driving evolution in the pelagic realm and contrast it with the better-known terrestrial realm.
