Variation of hind-wing colour and length in <i>Sympetrum internum</i> (Odonata: Libellulidae) from the Canadian prairie provinces
Bibliographic record
Abstract
Abstract Amber coloration, called saffroning, extends from 1 to 15 mm across the hind-wing base in females of Sympetrum internum Montgomery from the prairie provinces but extends only from 2 to 3 mm in males. There are no substantial differences in hind-wing length between the sexes. A significant correlation was found between hind-wing length and the extent of saffroning for both males and females. Regressions of these characters against latitude and longitude revealed that (1) there is a significant decrease in hind-wing length northward for both sexes; (2) there is a significant decrease in saffroning northward that is more significant for females; (3) there is no significant effect of longitude on hind-wing length; and (4) saffroning in females significantly increases westward but there is no similar effect in males, and the trend in females is much less significant than the latitudinal trend. Within the prairie provinces, extensive saffroning is confined to the Prairie Ecozone and moderate saffroning occurs around the edges of this ecozone. The surrounding Boreal Plains Ecozone is characterized by females with very limited saffroning. There is generally extensive variation in the extent of saffroning within some Prairie Ecozone locations, ranging from limited to moderate or extensive, but limited and moderate saffroning were more frequent at most locations in the Prairie Ecozone. Various explanations for saffroning are considered. Since limited, moderate, and extensive saffroning occur together throughout an extensive area, and occur within many populations and within a group emerging at the same time, formal taxonomic recognition of individuals with moderate or extensive saffroning seems unwarranted.

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.
