Dinoflagellates are common to abundant in both marine and freshwater environments. They are particularly diverse in the marine plankton where some cause “red tides” and other harmful blooms. More than 2,000 extant species have been described, only half of which are photosynthetic. They include autotrophs, mixotrophs and grazers. They are biochemically diverse, varying in photosynthetic pigments and toxin production ability. Some are important sources of bioluminescence in the ocean. They can… 

Genomes of the dinoflagellate Polarella glacialis encode tandemly repeated single-exon genes with adaptive functions

Because most dinoflagellate genes are constitutively expressed, Polarella glacialis has enhanced transcriptional responses via unidirectional, tandem duplication of single-exon genes that encode functions critical to survival in cold, low-light polar environments.

Pigment compositions are linked to the habitat types in dinoflagellates

Results clarify that far greater diversity of pigments are produced by the dinoflagellates living in sand regardless of chloroplast types relative to those of planktonic and tidal pool forms.

Diversity and Ecology of Eukaryotic Marine Phytoplankton

The composition and new records of micro- and mesophytoplankton near the Vitória-Trindade Seamount Chain

The high species diversity, especially among dinoflagellates can be considered typical of tropical oligotrophic waters, and the gap in knowledge of phytoplankton biodiversity in Brazil is demonstrated.

A Review on the Biodiversity and Biogeography of Toxigenic Benthic Marine Dinoflagellates of the Coasts of Latin America

Many benthic dinoflagellates are known or suspected producers of lipophilic polyether phycotoxins, particularly in tropical and subtropical coastal zones. These toxins are responsible for diverse

Global Diversity of Aloricate Oligotrichea (Protista, Ciliophora, Spirotricha) in Marine and Brackish Sea Water

The ecophysiological diversity is considerably larger than the morphological, and even tops the richness of SSrRNA and ITS haplotypes, indicating that probably more than 83–89% of the diversity in aloricate Oligotrichea are unknown.

A quantitative review of the lifestyle, habitat and trophic diversity of dinoflagellates (Dinoflagellata, Alveolata)

The continental waters are highly dominated by plastid-containing species, while in marine environments there is a slight dominance of heterotrophic species (58%).

Species diversity of dinophysoid dinoflagellates in the Clarion–Clipperton Fracture Zone, eastern Pacific

Almost half the number of species recorded before in the eastern Pacific (including coastal samples) was observed, corresponding to about one-fifth of the known dinophysoid diversity.

Polar Marine Microbiology

This chapter presents a brief overview of pelagic microbes and their diversity, vertical distribution, and influences on biogeochemistry and upper food webs following the application of molecular biological techniques to polar marine systems.



Bipolar distribution of the cyst-forming dinoflagellate Polarella glacialis

Morphological and molecular data support the assignment of the Arctic strain to P. glacialis, which up to now was known only from Antarctic sea ice.

An introduction to the biogeography of aquatic microbes

In this review, recent results exploiting techniques of molecular biology are summarized to place in perspective the studies of this Theme Section, which concern large-scale patterns of spatial distribution among heterotrophic planktonic prokary- otic and eukaryotic microbes.

An Ice-Bound Planktonic Dinoflagellate Peridiniella catenata (Levander) Balech: Morphology, Ecology and Distribution

It is concluded that Peridiniella catenata is one of a few Arctic-boreal dinoflagellates, and cold-water, euryhaline, brackish-water-marine, ice-bound planktonic species, which is able to develop in abundance in the sea ice.

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.

The evolution of dinoflagellates

This work postulates that dinoflagellates with two anterior flagella and a wall consisting of two large valves were successful through much of the Paleozoic, and the plate fragmentation model is proposed.

Transport of diatom and dinoflagellate resting spores in ships' ballast water: implications for plankton biogeography and aquaculture

The present work indicates that the most effective measure to prevent the spreading of toxic dinoflagellate cysts via ships' ballast water would be to avoid taking on ballast water during din oflageLLate blooms in the water column of the world's ports.

Physiological ecology of harmful algal blooms

Dinoflagellate Nuclear SSU rRNA Phylogeny Suggests Multiple Plastid Losses and Replacements

To trace the gain and loss of plastids in dinoflagellates, the nuclear small subunit rRNA gene is sequenced of 28 photosynthetic and four non-photosynthetic species, and phylogenetic trees with a total of 81 dinof lagellate sequences are produced.

The early Mesozoic radiation of dinoflagellates

Dinoflagellates are a major component of the marine microplankton and, from fossil evidence, appear to have been so for the past 200 million years. In contrast, the pre-Triassic record contains only
