Abstract

<em>Abstract</em>.—There are 11 lamprey species in Canada: Vancouver lamprey <em>Entosphenus macrostomus</em> (formerly <em>Lampetra macrostoma</em>), Pacific lamprey <em>Entosphenus tridentatus</em> (formerly <em>Lampetra tridentata</em>), chestnut lamprey <em>Ichthyomyzon castaneus</em>, northern brook lamprey <em>Ichthyomyzon fossor</em>, silver lamprey <em>Ichthtyomyzon unicuspis</em>, river lamprey <em>Lampetra ayresii</em>, western brook lamprey <em>Lampetra richardsoni</em>, Alaskan brook lamprey <em>Lethenteron alaskense</em>, American brook lamprey <em>Lethenteron appendix</em> (formerly <em>Lampetra appendix</em>), Arctic lamprey <em>Lethenteron camtschaticum</em> (formerly <em>Lampetra camtschatica</em>), and sea lamprey <em>Petromyzon marinus</em>. <em>Entosphenus</em> and <em>Lethenteron</em> were previously synonymized with <em>Lampetra</em>, but Nelson (2006) recognized these as three distinct genera. Conservation status has been assessed in only five species and in two of these (western brook lamprey and chestnut lamprey), only for portions of their Canadian population. The 2007 Committee on the Status of Endangered Wildlife in Canada list indicates that the enigmatic population of western brook lamprey in Morrison Creek, British Columbia, is endangered; the Vancouver lamprey in British Columbia is threatened; the chestnut lamprey in Saskatchewan and Manitoba is special concern; the northern brook lamprey in Manitoba, Ontario, and Quebec is of special concern in the latter two provinces and data deficient in the former; and the Alaskan brook lamprey in the Northwest Territories is data deficient. The threats to the four species at risk were collectively related to habitat degradation and loss, sensitivity to a catastrophic event, and sensitivity to lampricide used to control the invasive sea lamprey in the Great Lakes basin. Despite much lamprey work being conducted in the past decade, there still remain a number of knowledge gaps. These gaps include unequivocal evidence as to whether parasitic and nonparasitic members of a paired species should be considered distinct species and information on the distribution and population sizes and trends of the native lamprey species.

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.
