Six new marine species of the genus <i>Paulinella</i> (Rhizopoda: Filosea, or Rhizaria: Cercozoa)
Bibliographic record
Abstract
Six new marine species of the testate amoebid genus Paulinella are described using light and electron microscopic observations of material from Canada's Pacific Ocean coastal waters. In order of test (shell) size, from smallest to largest, the following new species are proposed: P. carsoni sp. nov., P. agassizi sp. nov., P. suzukii sp. nov., P. lauterborni sp. nov., P. multipora sp. nov. and P. gigantica sp. nov. Included in this survey are new observations on P. indentata Hannah, Rogerson & Anderson, from Canadian Pacific Ocean locations, but previously known only from Scottish coastal waters, and the common brackish/freshwater species P. chromatophora, from Ontario (Canada). These new discoveries more than double the number of previously known species of Paulinella, a genus significant for its role as a secondary producer in marine benthic ecosystems and for the possible role of its type species (P. chromatophora) as a model system for the endosymbiosis hypothesis of the evolution of chloroplast-bearing organisms.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
