Leatherback turtles (Dermochelys coriacea) in Newfoundland and Labrador: distribution, diet, threats and the use of education in recovery efforts
Bibliographic record
Abstract
Leatherback turtles (Dermochelys coriacea) are critically endangered (IUCN) throughout their range which extends into waters off Newfoundland and Labrador (NL). Geo-referenced sightings, strandings and entrapments were used to map distribution in relation to bathymetry, and remotely-sensed sea surface temperature and chlorophyll density data. Coastal waters (< 50 m in depth) characterized by the warm seasonal layer and increased medusan abundance provide critical leatherback habitat. Caloric content of two jellyfish species (Aurelia aurita and Cyanea capillata) were determined using bomb calorimetry and used to extrapolate energy requirements of leatherbacks while foraging in northern waters. Daily food energy requirements (43-155% of body mass) confirm the need for high density jellyfish aggregations during their foraging season. While foraging off NL leatherbacks are at risk for entrapment in all types of fishing gear, with the number of entrapments greatest in August and September, and along the south coast. Necropsy results indicate ingestion of plastic debris is a definite threat, while injuries associated with stranding events suggest vessel collisions should also be considered a potential threat. Species at risk education initiatives were also considered. An objective of this study was to examine the current curricula in NL with regards to species at risk, and to evaluate an educational programme aimed at teaching school-aged children about the biology of, and threats to, leatherback turtles.

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.
