Thermal constraints and the influence of reproduction on thermoregulation in a high‐altitude gecko (<i>Quedenfeldtia trachyblepharus</i>)
Bibliographic record
Abstract
Abstract Temperature plays a crucial role for ectotherm performance and thus for fitness. Terrestrial ectotherms, including reptiles, regulate their body temperature mainly by behavioural means. At high altitude, however, thermal constraints make precise thermoregulation costly. The cost–benefit model of lizard thermoregulation predicts that thermally challenging environments should favour the evolution of thermoconformity. Yet, several species maintain high and stable body temperatures even in cool environments. We studied the Atlas Day Gecko, Quedenfeldtia trachyblepharus, a cold‐adapted lizard endemic to the High Atlas Mountains of Morocco. We quantified thermoregulation in gravid females, non‐gravid adult females, and adult males during the active season. Geckos thermoregulated during their active season, and thermoregulated with more effectiveness early in the season than late in the season. In the laboratory, the preferred body temperature ranges of gravid females, non‐gravid females, and males were not significantly different. In the field, however, gravid females had smaller deviations from the preferred body temperature and maintained higher body temperatures than males and non‐gravid females. Our study suggests that cold‐adapted reptiles adjust their thermoregulatory behaviour in response to thermal constraints and reproductive status.

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.
