The Marine Microbial Eukaryote Transcriptome Sequencing Project (MMETSP): Illuminating the Functional Diversity of Eukaryotic Life in the Oceans through Transcriptome Sequencing
TLDR
This Community Page describes a resource of 700 transcriptomes from marine microbial eukaryotes to help understand their role in the world's oceans.
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
Trophic transfer of fatty acids, sterols, and a triterpenoid alcohol between bacteria, a ciliate, and the copepod Acartia tonsa
TLDR
The results suggest that bacterivorous ciliates may not provide copepod with adequate nutritional requirements for long-term survival, but that lipids unique to bacteria and ciliate can be assimilated by and may provide useful tracers of consumption by copepods.
Insights into the diversity of choreotrich and oligotrich ciliates (Class: Spirotrichea) based on genealogical analyses of multiple loci.
TLDR
Analysis of multi-locus sequence analyses indicate that, at least for some ciliate lineages, DNA polymorphisms vary temporally, and that genetic heterogeneity underlies some very similar morphological types.
Planktonic community structure determines the fate of bacterial production in a temperate lake
TLDR
Large populations of Daphnia effectively “break” the microbial loop and funnel bacterial production to higher consumers in Upton Lake, New York, and most bacterial communities appear to have turnover times substantially > 1 d.
Do Bacteria-Sized Marine Eukaryotes Consume Significant Bacterial Production?
TLDR
Evidence is presented that previously uncharacterized, small eukaryotes that are able to pass even 0.6-micrometer filters may be responsible for a large fraction of the total grazing in coastal waters.
Lipid Composition of the Marine Ciliates Pleuronema sp. and Fabrea salina: Shifts in Response to Changes in Diet 1
TLDR
Using a series of antibiotic treatments to alter the bacterial prey community, and thus fatty acids composition of the ciliate's diet, promoted changes in the fatty acid composition of Pleuronema sp.
Reframing the Everything is everywhere debate: evidence for high gene flow and diversity in ciliate morphospecies
TLDR
The analyses of genetic variation in ciliate mor- phospecies isolated from ephemeral environments (freshwater ponds and tide pools) redefine this debate and indicate that models of microbial diversity must test for ecologically driven patterns in the interactions of gene flow and species richness to account for observed patterns of high dispersal and high gene flow.
