Abstract
Abstract Sea lampreys, Petromyzon marinus, are invasive to the Laurentian Great Lakes where they have decimated native fishes. Great Lakes sea lampreys have been subjected to control measures for several decades, and the drive to control them has led to major advances in understanding their biology and in informing management. In contrast, anadromous sea and Pacific (Entosphenus tridentatus) lampreys have co-evolved with their oceanic prey. Both of these anadromous lampreys are in decline, and a limited amount of information on their biology has stymied conservation. The tendency has been to make biological inferences about anadromous lampreys based on the Great Lakes sea lamprey without justifiable evidence. We identify areas in which key information is missing for the juvenile (parasitic feeding) phase and adult freshwater spawning migrations, and compare and contrast information for these lampreys. Our comparisons reveal major differences, some intriguing similarities, and key unknowns that will require empirical testing. Resumen la lamprea marina, Petromyzon marinus, es una especie invasiva de la región de los grandes lagos de los Estados Unidos de Norteamérica, en los cuales han diezmado las poblaciones de peces nativos. La lamprea marina de los grandes lagos ha sido sujeto de medidas de control por varias décadas y esta necesidad ha dado lugar a importantes avances en el entendimiento de su biología y manejo. En contraste, la lamprea anádroma y la del Pacífico (Entosphenus tridentatus) han co-evolucionado con sus presas oceánicas. Actualmente las poblaciones de ambas lampreas se encuentran en declive y la escasez de información sobre su biología ha interferido con su conservación. La tendencia ha sido hacer, sin evidencia que lo justifique, inferencias acerca de la lamprea del Pacífico sobre la base de lo que se conoce de la lamprea de los grandes lagos. Se identificaron áreas en las que se carece de información crítica de la fase juvenil (alimentación parasitaria) y de las migraciones reproductivas de los adultos y se comparó y contrastó información para estas lampreas. La comparación reveló diferencias significativas, algunas similitudes interesantes e interrogantes clave que demandarán de comprobación empírica.

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 it
