Multiple marker parallel tag environmental DNA sequencing reveals a highly complex eukaryotic community in marine anoxic water
TLDR
It is suggested that current understanding of the ecological complexity of protist communities, genetic diversity, and global species richness are severely limited by the sequence data hitherto available, and long‐tailed rank abundance curves suggest that the 454 sequencing approach provides improved access to rare genotypes.
Microeukaryote Community Patterns along an O2/H2S Gradient in a Supersulfidic Anoxic Fjord (Framvaren, Norway)
TLDR
A cultivation-independent 18S rRNA survey in the superanoxic Framvaren Fjord in Norway revealed the fine-scale architecture of anoxic protistan communities, which may exhibit adaptation to different environmental conditions along the steep O2/H2S gradient.
Microbial eukaryotes in the hypersaline anoxic L'Atalante deep-sea basin.
TLDR
It is hypothesized that extreme environments may exert a high selection pressure possibly resulting in the evolution of an exceptional and distinctive assemblage of protists in the deep hypersaline anoxic basins in the Mediterranean Sea.
Microbial eukaryote life in the new hypersaline deep-sea basin Thetis
TLDR
Several distinct morphotypes in brine samples suggest that the rRNA sequences detected in Thetis brine can be linked to indigenous polyextremophile protists, contradicting previous assumptions that such extremely high salt concentrations are anathema to eukaryotic life.
A Molecular Approach to Identify Active Microbes in Environmental Eukaryote Clone Libraries
TLDR
A comparison of the two libraries identified phototrophic dinoflagellates, “uncultured marine alveolates group I,” and different parasites, which were exclusively detected with the rDNA-derived library, as nonindigenous members of the anoxic microeukaryote community under study.
A morphogenetic survey on ciliate plankton from a mountain lake pinpoints the necessity of lineage-specific barcode markers in microbial ecology
TLDR
This study makes evident that taxon abundance distributions inferred from amplicon data are highly biased and do not mirror actual morphotype abundances at all and underline the necessity of barcoding initiatives for eukaryotic microbes to better and fully exploit environmental ampliconData sets.
High diversity of protistan plankton communities in remote high mountain lakes in the European Alps and the Himalayan mountains
TLDR
The genetic diversity (V4 region of the 18S rRNA) of planktonic microbial eukaryotes in four high mountain lakes including two remote biogeographic regions (the Himalayan mountains and the European Alps) and distinct habitat types was far beyond what is described from high mountain lake plankton.
Diversity and endemism of ciliates inhabiting Neotropical phytotelmata
TLDR
The data show the number of potential Neotropical phytotelmata-endemic ciliate species increasing as more phytolmata are sampled, and the supposed endemics are mainly recruited from moss and ephemeral limnetic habitats, which shows that the bromeliad ciliate fauna is quite distinct from those of otherLimnetic habitats.
Morphological and Molecular Characterization of Some Peritrichs (Ciliophora: Peritrichida) from Tank Bromeliads, Including Two New Genera: Orborhabdostyla and Vorticellides.
TLDR
Using standard methods, the morphology and 18S rDNA sequence of some peritrich ciliates from tank bromeliads of Costa Rica, Jamaica, and Ecuador are studied and Vorticella gracilis is neotypified with the Austrian population studied by Foissner (1979).
Evidence for isolated evolution of deep-sea ciliate communities through geological separation and environmental selection
TLDR
It is concluded that community assembly in DHABs is a mixture of isolated evolution (as evidenced by small changes in V4 primary structure in some taxa) and species sorting (as indicated by the regional absence/presence of individual taxon groups on high levels in taxonomic hierarchy).
