Abstract
Cold tolerance is important in defining the distribution of insects. Here, we review the principal physiological mechanisms underlying homeostatic failure during cold exposure in this diverse group of ectotherms. When insects are cooled sufficiently, they suffer an initial loss of neuromuscular function (chill coma) that is caused by decreased membrane potential and reduced excitability of the neuromuscular system. For chill-susceptible insects, chronic or severe chilling causes a disruption of ion and water homeostasis across membranes and epithelia that exacerbate the initial effects of chilling on membrane potential and cellular function, and these perturbations are tightly associated with the development of chill injury and mortality. The adaptation and acclimation responses that allow some insects to tolerate low temperatures are multifactorial and involve several physiological systems and biochemical adjustments. In this review, we outline a physiological model that integrates several of these responses and discuss how they collectively help to preserve cellular, organ, and organismal homeostasis at low temperature.

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
