Novel kingdom-level eukaryotic diversity in anoxic environments
Open accessAbstract
Molecular evolutionary studies of eukaryotes have relied on a sparse collection of gene sequences that do not represent the full range of eukaryotic diversity in nature. Anaerobic microbes, particularly, have had little representation in phylogenetic studies. Such organisms are the least known of eukaryotes and probably are the most phylogenetically diverse. To provide fresh perspective on the natural diversity of eukaryotes in anoxic environments and also to discover novel sequences for evolutionary studies, we conducted a cultivation-independent, molecular phylogenetic survey of three anoxic sediments, including both freshwater and marine samples. Many previously unrecognized eukaryotes were identified, including representatives of seven lineages that are not specifically related to any known organisms at the kingdom-level and branch below the eukaryotic “crown” radiation of animals, plants, fungi, stramenopiles, etc. The survey additionally identified new sequences characteristic of known ecologically important eukaryotic groups with anaerobic members. Phylogenetic analyses with the new sequences enhance our understanding of the diversity and pattern of eukaryotic evolution.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
