Body temperatures of leatherback turtles (Dermochelys coriacea) in temperate waters off Nova
Bibliographic record
Abstract
Abstract: The leatherback sea turtle, Dermochelys coriacea (Vandelli, 1761), has the most extensive range of any rep-tile, migrating from tropical and subtropical nesting areas to distant foraging habitats, including those in temperate and even boreal waters. This implies flexible thermal functioning. It has been inferred that leatherbacks support active for-aging by keeping warm in cold water, rather than becoming lethargic as other marine turtles do. However, data consis-tent with this view have come from captive turtles in unnatural and stressful conditions. In the present case, foraging leatherbacks were captured at sea off Nova Scotia and their body temperature recorded within 10 min, before such large animals could change their body temperatures appreciably. Mean excess temperature over that of the sea surface (15.0–16.7 °C) averaged 8.2 °C. These results attest to, but underestimate, the capacity of free-swimming leatherbacks to keep warm in northern waters, as data from another turtle that was instrumented to record ocean temperature while diving revealed that leatherbacks foraging in this area at the same time of year may spend 40 % of their time diving to waters cooler than the surface. Résumé: La tortue luth, Dermochelys coriacea (Vandelli, 1761), possède l’aire de répartition la plus étendue de tous les reptiles, car elle migre de son aire de nidification tropicale ou subtropicale vers ses habitats lointains de recherche de nourriture qui incluent les eaux tempérées et même les eaux boréales. Un tel comportement suppose un fonctionne-ment thermique flexible. On en a déduit que les tortues luths maintiennent leur recherche active de nourriture en de-

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
