Forensic palynology and ethnobotany of <i>Salicornia</i> species (Chenopodiaceae) in northwest Canada and Alaska
Bibliographic record
Abstract
Pollen grains from bodies of ancient people provide clues to their diet and domicile. To learn more about Kwädāy Dän Ts'ìnchí (Long Ago Person Found), who died on a British Columbia glacier 550 years ago, we studied the Chenopodiaceae pollen found in his stomach and robe. Environmental scanning electron microscopy was used to distinguish pollen of the native chenopod genera Atriplex, Chenopodium, Eurotia, Suaeda, and Salicornia (here including Sarcocornia). All chenopod pollen grains in one stomach sample were from Salicornia (Tourn.) L. (glasswort), which grows only in saline soils and has been used for food and medicine. Elders from the Champagne and Aishihik, Tagish, Gwitch'in, and Tlingit First Nations report their ethnobotanical and historical knowledge about inland and coastal Salicornia species. There is no common use for the small inland annual glasswort, Salicornia rubra A. Nelson, although other species were used for grain further south; however, Pacific Northwest coastal people have eaten the succulent perennial glasswort, Salicornia perennis Miller, since at least the 1880s. Pollen grains of this perennial salt marsh species are most similar to the chenopod pollen grains in the stomach of Kwädāy Dän Ts'ìnchí and suggest the ancient man's last meal came from the coast rather than from inland.Key words: Chenopodiaceae, Salicornia, Sarcocornia, forensic palynology, frozen body, ethnobotany.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
