Abstract
We evaluated the basal metabolic rate (BMR), thermal conductance (Cm), and lower critical temperature (Tlc) of Leach’s Storm-petrel (Oceanodroma leucorhoa) using open-flow respirometry. Measurements were taken from six adults collected at their nests at Great Island, Witless Bay Ecological Reserve, Newfoundland, Canada. In order to establish Tlc and Cm, we determined rates of oxygen consumption after exposing birds to different ambient temperatures (10°C, 20°C, 26°C, and 30°C). Storm-petrels had a minimal Cm of 0.122 ± 0.019 ml O2/g·°C·h and Tlc was 24°C. The basal rate of oxygen consumption was 1.85 ± 0.24 ml O2/g·h. Incubating Leach’s Storm-petrels had a basal rate of metabolism lower than previously reported for this species. Possible explanations for this discrepancy include the use of different techniques to measure metabolic rates, and the physiological state of the birds being measured. In this respect, our results coupled with those from previous studies, suggest decreased metabolic rates in incubating Procellariformes compared to those of non-reproducing birds measured at the same temperature. This decline in metabolism is possibly related to metabolic depression due to fasting.

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
