Abstract

fetched live from OpenAlex

A total of 59 plants from 30 populations of 15 species of Carex sect. Phacocystis (including Carex bicolor as outgroup) from eastern Canada and northern Europe were investigated for genetic differentiation of taxa using AFLP. Seven species were studied with material from both Europe and America, three species were investigated with North American material only and five species with European material only. The neighbour joining analysis (NJ) indicates that Carex bicolor may not belong to section Phacocystis , while all other investigated species clearly belong to this section. The sorting of the species according to NJ and UPGMA is mostly in accordance with accepted taxonomy, but with the exceptions that the American C. bigelowii ssp. bigelowii may be specifically distinct from European C. bigelowii ssp. rigida , and C. stans should perhaps not be considered a subspecies or variety of C. aquatilis , but either as a separate species or as a hybrid between C. aquatilis and C. bigelowii . North American C. aquatilis is heterogenic and may contain more than one species.

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.

Full frame distilled prediction

Teacher imitation

Not 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.
