Bibliographic record
Abstract
This dataset contains the digitized treatments in Plazi based on the original journal article Alibert, Marie, Hamilton, Paul B., Pienitz, Reinhard, Antoniades, Dermot (2023): Small naviculoid species of Kobayasiella Lange-Bertalot, Adlafia Moser, Lange-Bertalot & Metzeltin, Nupela Vyverman & Compère and Sellaphora Mereschowsky from Tursujuq National Park, Hudson Bay region, Nunavik, Québec. Cryptogamie, Algologie 20 (9): 157-187, DOI: 10.5252/cryptogamie-algologie2023v44a9, URL: https://sciencepress.mnhn.fr/sites/default/files/articles/pdf/algologie2023v44a9.pdfABSTRACTSeven species from the genera Kobayasiella (K. madumensis JØrgensen, K. micropunctata Germain, K. parasubtilissima Kobayasi & Nagumo, K. pseudostauron Lange-Bertalot, K. subtilissima P.T.Cleve), Adlafia (A. bryophila Petersen) and Nupela (N. tenuicephala Hustedt) from oligotrophic lakes of the subarctic boreal zone in Tursujuq National Park in Nunavik (northern Québec, Canada), were studied by light and scanning electron microscopy and linked with environmental conditions. In addition, four new species, Kobayasiella tursujuqensis sp. nov., Adlafia umiujaqensis sp. nov., Adlafia ossiformis sp. nov., and Sellaphora vincentiana sp. nov., were observed and described. The new species are similar in light microscope observations to other species in their associated genera, but can be identified based on independent character traits under a combined LM and SEM analysis. Morphological structures of particular interest include valve outline, position of the central and terminal raphe fissures, orientation of the striae, and the structural formation of the areolae within the striae. Due to low taxon abundances, distribution patterns of these species in the park were difficult to identify. Kobayasiella parasubtilissima, K. subtilissima, K. tursujuqensis sp. nov. and N. tenuicephala were associated with acidic conditions while K. pseudostauron, A. bryophila and S. vincentiana sp. nov. were found in circumneutral waters. A better knowledge of small naviculoid species is necessary to document the circumpolar biogeography and ecology of diatoms for a better understanding of the dynamic of those organisms in changing environmental conditions within the context of rapid climate change in northern regions.

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.
