Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

The Czech Republic lies in the centre of Europe and from the point of view of hydrology its territory belongs to three drainage areas – those of the North Sea, Black Sea and Baltic Sea. This fact has an important influence on abundant species diversity of its ichthyofauna. The occurrence of 94 species of lampreys and fish of 13 orders and 23 families was historically confirmed here both in natural waters and fish cultures. Some of them are already extinct. Another 24 species face various levels of endangerment. The Czech-Canadian project within the iBOL initiative analyzed about 1,500 individuals from about 200 locations. Using a comprehensive approach (morphology, DNA barcoding, nDNA analysis) the haplotype variability was identified and pure species from hybrids were differentiated. At least in 5 genera, higher species variability than that described in literature was identified. DNA barcodes for about 72 recent indigenous and non-indigenous species were prepared. A new reference collection of all fish species of the Czech Republic for the National Museum was assembled. Efficiency of a new identification method, S7indel diagnostics, for taxonomic and biodiversity purposes was evaluated.

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.
