The phylum Ciliophora plays important roles in a wide range of biological studies. However,
the evolutionary relationships of many groups remain unclear due to a lack of sufficient …

Aquatic microbes, like all organisms, have biogeographies, but this subject has attracted
relatively little attention. In this review, recent results exploiting techniques of molecular …

Oligotrichids and choreotrichids are ciliate taxa contributing to the multi-step microbial food
web and episodically dominating the marine microzooplankton. The global diversity and …

Abstract About 4,500 free-living ciliate morphospecies have been described, applying an
average synonymy rate of 20%. We estimate that 83–89% of the ciliate diversity is still …

Deep-sequencing technologies are becoming nearly routine to describe microbial
community composition in environmental samples. The 18S ribosomal DNA (rDNA) …

An accurate reconstruction of the eukaryotic tree of life is essential to identify the innovations
underlying the diversity of microbial and macroscopic (eg, plants and animals) eukaryotes …

Background Our understanding of the eukaryotic tree of life and the tremendous diversity of
microbial eukaryotes is in flux as additional genes and diverse taxa are sampled for …

Tintinnid ciliates, characterized by the possession of a lorica into which the ciliate cell can
contract, are a common component of the marine microzooplankton. Lorica architecture and …

Assessment of the distribution and diversity of free-living protists is currently hampered by a
limited taxonomic resolution of major phyla and by neglecting the significance of spatial and …

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 …
