Microbial diversity associated with a <i>Paralvinella sulfincola</i> tube and the adjacent substratum on an active deep‐sea vent chimney
Bibliographic record
Abstract
ABSTRACT An extensive survey of the bacterial and archaeal phylogenetic diversity associated with a Paralvinella sulfincola tube and the adjacent substratum was conducted. Phylogenetic groups characterized by anaerobic and/or microaerophilic mesophiles dominated the bacterial 16S rDNA libraries (ɛ‐group F, Sulfurospirillum‐group, δ‐Proteobacteria). The two libraries also contained groups with thermophilic lifestyles (ɛ‐group D, Caldithrix‐group), groups comprising species with various phenotypes (ɛ‐group B, green non‐sulfur bacteria), and a group without cultured representative (ɛ‐group C). Archaeal 16S rDNA libraries from both samples were dominated by the novel lineage DHVE 9, and contained members of the uncultured group DHVE 3, as well as anaerobic hyperthermophiles from the families Thermofilaceae and Thermococcaceae. These results suggest the presence of mostly mesophilic and low oxygen conditions on the chimney surface, which is in accordance with descriptions of P. sulfincola's habitat conditions. Although limited by the lack of replicates, our data on the P. sulfincola tube were compared to available data on the microbial communities associated with secretions from other deep‐sea vent polychaetes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
