The Marine Microbial Eukaryote Transcriptome Sequencing Project (MMETSP): Illuminating the Functional Diversity of Eukaryotic Life in the Oceans through Transcriptome Sequencing
Current sampling of genomic sequence data from eukaryotes is relatively poor, biased, and inadequate to address important questions about their biology, evolution, and ecology; this Community Page… Expand

Trophic transfer of fatty acids, sterols, and a triterpenoid alcohol between bacteria, a ciliate, and the copepod Acartia tonsa
The incorporation of lipids into the copepod Acartia tonsa and its eggs was measured when it was fed either a bacterivorous ciliate (Pleuronema sp.) or a diatom (Thalassiosira weissflogii). Egg… Expand

Insights into the diversity of choreotrich and oligotrich ciliates (Class: Spirotrichea) based on genealogical analyses of multiple loci.
To examine relationships among spirotrich ciliates using multi-locus sequence analyses and to provide preliminary insights into molecular diversity within species, we sequenced the small subunit rDNA… Expand

Picophytoplankton biomass distribution in the global ocean
Abstract. The smallest marine phytoplankton, collectively termed picophytoplankton, have been routinely enumerated by flow cytometry since the late 1980s during cruises throughout most of the world… Expand

The nearshore zone during coastal upwelling: Daily variability and coupling between primary and secondary production off central Chile
The nearshore region of central Chile is important for spawning of sardine (Sardinops sagax) anchovy (Engraulis ringens) and jack mackerel (Trachurus murphyii) and the importance of fisheries for… Expand

Marine ciliates as a widespread source of tetrahymanol and hopan-3β-ol in sediments
We observed tetrahymanol (gammaceran-3β-ol) as a principal neutral lipid in eight marine ciliate species, most of which were scuticociliates, a group of ciliates that feeds mainly on bacteria.… Expand

Lipid Composition of the Marine Ciliates Pleuronema sp. and Fabrea salina: Shifts in Response to Changes in Diet 1
ABSTRACT. The composition and incorporation of lipids in two marine ciliates, Pleuronema sp. and Fabrea salina, was examined following growth on either an algal or bacterial diet. When allowed to… Expand

Reframing the Everything is everywhere debate: evidence for high gene flow and diversity in ciliate morphospecies
Current debate on microbial diversity contrasts the 'cosmopolitan' hypothesis, which argues for high gene flow and low diversity, with the 'endemism' hypothesis, which argues for high diversity and… Expand

Utility of genetic markers and morphology for species discrimination within the order Tintinnida (Ciliophora, Spirotrichea).
We evaluated the small- and large-subunit rDNA (SSU and LSU, respectively) for their ability to discriminate morphospecies of tintinnid ciliates. Multiple individuals from 29 morphospecies were… Expand

Do Bacteria-Sized Marine Eukaryotes Consume Significant Bacterial Production?
Up to 60 percent of the total marine primary production (or about one-fourth of the total global carbon dioxide fixation) passes through the free-living bacterioplankton. Grazing by bacteriovores is… Expand
