Abstract

fetched live from OpenAlex

Premise of the Study Identifying roots to species is challenging, but is a common problem in ecology. Fluorescent amplified fragment length polymorphisms ( FAFLP s) can distinguish species within a mixed sample, are high throughput, and are inexpensive. To broaden the use of this tool across ecosystems, unique size profiles must be established for species, and its limits identified. Methods Fragments of three noncoding cp DNA regions were used to create size profiles for 193 species common to the western Canadian boreal forest. We compared detection success among congeners using FAFLP s and Sanger sequencing of the trnL intron. We also simulated and experimentally created communities to test the influence of species richness, cp DNA regions used, and extraction/amplification biases on detection success. Results Of the 193 species, 54% had unique size profiles. This value decreased when fewer cp DNA regions were used. In simulated communities, ambiguous species identifications were positively related to the species richness of the community. In mock communities, some species evaded detection owing to poor extraction or amplification. Sequencing did not increase detection success compared to FAFLP s for a subset of 24 species across nine genera. Discussion We recommend FAFLPs are best suited to confirm rather than discover species occurring belowground.

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.
