Abstract

fetched live from OpenAlex

Species of the Chironomus group from Lake Winnipeg, Manitoba, Canada are listed and taxonomic and ecological notesgiven. Chironomus (C.) entis Shobanov and C. (C.) bifurcatus dominates the bottom fauna with minor occurrence of fourother larval types. Fourteen species of Chironomus Meigen, one Chaetolabis Townes, and one Lobochironomus Ryser,Wülker et Scholl; one species of Benthalia Lipina, and one Einfeldia Kieffer are present in the light traps. Chironomus(Lobochironomus) sp. and Benthalia brunneipennis (Johannsen) are described on adult male. A key to the Nearctic malesof Einfeldia, Benthalia and Chironomus subgen. Lobochironomus is presented. The significance of the different Chi-ronomus species as indicators of trophic levels is demonstrated by their distribution in Lake Winnipeg. The separation of larval instars is shown approximately to follow Dyar’s rule.

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.
