Abstract

fetched live from OpenAlex

Abstract. Advances in sequencing technology and the environmental genomic approaches have brought attention to the vastness of protist biodiversity. While over much of the world’s oceans the species and phylotypes making up this diversity are assumed to be something previously hidden and now revealed, the recent rapid changes in the Arctic mean that such assumptions may be a simplification. Historical morphological species data can be used to validate new records provided that more of these species are identified using standard molecular markers. Environmental surveys can also go further by identifying species over regions, seasons and depths. High throughput sequencing and bioinformatics tools provide a means of monitoring and eventually predicting the consequences of change. We give an example of how microbial eukaryote communities differ over pan-arctic scales, emphasizing the need for additional sampling and the need for caution in extrapolating the results of one region to the entire Arctic.

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.

Not 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.
