Marine plankton support global biological and geochemical processes. Surveys of their biodiversity have hitherto been geographically restricted and have not accounted for the full range of plankton size. We assessed eukaryotic diversity from 334 size-fractionated photic-zone plankton communities collected across tropical and temperate oceans during the circumglobal Tara Oceans expedition. We analyzed 18S ribosomal DNA sequences across the intermediate plankton-size spectrum from the smallest… 

Global drivers of eukaryotic plankton biogeography in the sunlit ocean

This study uses Tara Oceans metabarcoding data covering all the major ocean basins combined with a probabilistic model of taxon co-occurrence to compare the biogeography of 70 major groups of eukaryotic plankton, revealing two main axes of biogeographic variation.

Diversity of Pico- to Mesoplankton along the 2000 km Salinity Gradient of the Baltic Sea

This study provides the first ultra-deep sequencing-based survey on eukaryotic and bacterial plankton biogeography in the Baltic Sea with results highlighting the importance of salinity for structuring the biodiversity within this ecosystem.

Functional repertoire convergence of distantly related eukaryotic plankton lineages abundant in the sunlit ocean

The first, to the authors' knowledge, comprehensive genome-wide functional classification of abundant unicellular eukaryotic plankton, revealing four major groups connecting distantly related lineages.

Specific eukaryotic plankton are good predictors of net community production in the Western Antarctic Peninsula

The results indicate that defining plankton communities at a deeper taxonomic resolution than by functional groups and accounting for the differences in size and coupling between groups can substantially improve organic carbon flux predictions.

Patterns of eukaryotic diversity from the surface to the deep-ocean sediment

Remote deep-ocean sediment (DOS) ecosystems are among the least explored biomes on Earth. Genomic assessments of their biodiversity have failed to separate indigenous benthic organisms from sinking

Seasonal dynamics of marine protist communities in tidally mixed coastal waters

Major seasonal community reorganizations and associated biomass variations are landmarks of plankton ecology. However, the processes of plankton community turnover rates have not been fully

Unexpected biodiversity of ciliates in marine samples from below the photic zone

High‐throughput sequencing is used to analyse the spatial distribution of planktonic ciliate diversity from shallow waters to beyond the continental shelf along a 163 km transect off the coast of New England, USA, and it is observed that the ciliate communities assessed by HTS cluster by depth layer and degree of water column stratification, suggesting that community assembly is driven by environmental factors.



Unexpected diversity of small eukaryotes in deep-sea Antarctic plankton

Using ribosomal RNA genes from marine picoplankton, several new groups of bacteria and archaea have been identified, some of which are abundant and related to dinoflagellates that are found at all studied depths and suggest a radiation early in the evolution of alveolates.

Oceanic 18S rDNA sequences from picoplankton reveal unsuspected eukaryotic diversity

35 full sequences of the small-subunit (18S) ribosomal RNA gene derived from a picoplanktonic assemblage collected at a depth of 75 m in the equatorial Pacific Ocean are analysed and show that there is a high diversity of picoeukaryotes.

Molecular surveys of picoeukaryotes have unveiled a large phylogenetic diversity and new lineages, and it is critical to understand the ecological and evolutionary significance of this large and novel diversity.

Extreme diversity in noncalcifying haptophytes explains a major pigment paradox in open oceans

Estimates of depth-integrated relative abundance of 19-Hex indicate that haptophytes dominate the chlorophyll a-normalized phytoplankton standing stock in modern oceans, adding to the growing evidence that the evolution of complex microbial eukaryotic cells is a critical force in the functioning of the biosphere.

Molecular evidence of cryptic speciation in planktonic foraminifers and their relation to oceanic provinces.

The genetic data reveal the presence of three cryptic species, whose distribution is clearly correlated to hydrographic provinces, and particularly to sea-surface total chlorophyll a concentration, and suggest that a considerable part of the diversity among planktonic foraminifers has been overlooked in morphological taxonomies.

Study of Genetic Diversity of Eukaryotic Picoplankton in Different Oceanic Regions by Small-Subunit rRNA Gene Cloning and Sequencing

The diversity of marine picoeukaryotes was determined by sequencing cloned 18S rRNA genes in five genetic libraries from North Atlantic, Southern Ocean, and Mediterranean Sea surface waters, and the phylogenetic diversity in each library was rather great, and each library included many different OTUs and members of very distantly related phylogenetic groups.

Paleobiological perspectives on early eukaryotic evolution.

Protists continued to diversify along with animals in the more pervasively oxygenated oceans of the Phanerozoic Eon, and the Mid-Neoproterozoic establishment or expansion of eukaryophagy provides a possible mechanism for accelerating eUKaryotic diversification long after the origin of the domain.

Marine protistan diversity.

Studies of protistan diversity provide insight regarding how species richness and community composition contribute to ecosystem function and support the development of predictive models that describe how microbial communities will respond to natural or anthropogenically mediated changes in environmental conditions.

High Cryptic Diversity across the Global Range of the Migratory Planktonic Copepods Pleuromamma piseki and P. gracilis

It is hypothesize that these mtDNA lineages are distinct species and suggest that resolving their systematic status is important, given the ecological significance of the genus Pleuromamma in subtropical-tropical waters worldwide.

An original mode of symbiosis in open ocean plankton

A widespread symbiotic association between Acantharia biomineralizing microorganisms that are abundant grazers in plankton communities, and members of the haptophyte genus Phaeocystis that are cosmopolitan bloom-forming microalgae is described.
